Wordcatcher Tales: kazari moufu, kissuisen

On my most recent trip to Japan, I had the chance to go aboard two museum ships in Yokohama harbor. One was the former Japanese naval sail training ship, the Nippon Maru, a four-masted barque with auxiliary diesel engines. The other was the NYK Hikawa Maru, a former luxury passenger liner built for North Pacific routes between Japan and Seattle/Vancouver. Both ships were built in Kobe and made their maiden voyages in 1930.

kazari moufu

Decorative blanket folding

飾り毛布 kazari-moufu ‘decoration-blanket’ — Last year, when we toured the Hakkoda train ferry museum in Aomori, we noticed some ornamentally folded blankets in some of the ship’s cabins. According to Japanese Wikipedia, the practice of folding blankets into decorative shapes—like origami in wool—originated in 1908 on the ships ferrying passengers across the Seikan Strait between Aomori on Honshu and Hakodate on Hokkaido. (There is no other Wikipedia article in any language on the decorative folding of blankets.) This year I noticed and photographed the same phenomenon in officers’ berths aboard the Nippon Maru and in first-class passengers’ berths aboard the Hikawa Maru. The Japanese Wikipedia article also links to the FAQ page of an OSK passenger liner named Nippon Maru, whose last entry addresses the question of kazari-moufu. The English version of an explanatory sign outside a passenger cabin on the Hikawa Maru follows.

Ornamentally folded blankets, called “decorative blankets (Kazari-mofu)”, were common during the age of passenger ships. The blankets were folded by stewards and placed with care on passengers’ beds. The designs included flowers (Hana-mofu), a sunrise, and even the helmet of a samurai warrior, generating anticipation among many passengers about the day’s creation. The designs of flowers were originally called “floral blankets (Hana-mofu)” but as stewards became more creative with their designs, the name changed to “decorative blankets (Kazari-mofu)” to better reflect their creations.

waterline labels

Waterline inside Hikawa Maru

喫水線 kissuisen ‘waterline’ — On the lowest deck of the engine room, there was a red line just over head-high on the inside of the ship’s hull that marked the normal waterline, labeled in katakana uotaarain (< ‘waterline’) and in kanji as 喫水線 kissuisen, which translates literally as ‘eat/drink-water-line’. The first kanji shows up in compounds such as 喫茶店 kissaten ‘drink-tea-shop (= teahouse, coffee shop)’ and 喫煙室 kitsuenshitsu ‘drink-smoke-room (smoking room)’. But 喫水 kissui also means the ‘draft (of a ship)’, so ‘eat/drink-water’ is probably better glossed here as ‘displace-water’.

Language Documentation Hiatus

My slow and erratic progress on documenting Numbami, the language I did fieldwork on in Papua New Guinea in 1976, suddenly gained traction on October 1, when I imported my old Numbami dictionary file into a new software package I had just been introduced to. Now dictionary work has taken precedence over blogging, photography, and other hobbies as I tediously clean up the many import errors and add many cross-references and reverse-entry keywords. After the cleanup, I’ll have a printable Numbami-English and English-Numbami lexicon and be ready to digitize the text, glosses, and translations of several wonderful narratives I transcribed (in pencil) 35 years ago.

Before I imported the dictionary data, I had begun to retranscribe one of my best narratives whose pencil transcription had gone missing many years ago. A couple years ago, a language documentation specialist at the University of Hawai‘i (my old alma mater) had converted my old cassette tapes to digital media (.WAV and .MP3 format), so I could use Transcriber to align the audio with the transcription.

While underemployed in 1991, I had first input all my manual Numbami wordlist cards into Shoebox. In 2006, a friend helped me convert the Shoebox database into SIL’s new and improved Toolbox. Now I have imported the Toolbox data into SIL’s latest language documentation software package, FLEx, and have begun cleaning and recoding it.

One of the best things I did during my fieldwork was to record and transcribe in the field a good range of narratives: two well-organized procedural texts about women’s work cooking food and about the communal work of processing sago palm starch; two personal tales about experiences being civilians on the front lines during World War Two; and a couple of traditional tales, including an origin myth that combines elements from both coastal and inland cultures. (I translated and blogged a passage from one of the war stories here.)

My host father (long deceased) was a retired schoolteacher and village kaunsil (elected representative to the local government council). He told me that a portion of the timber royalties from village land was allocated to help pay for the education of village youths, who had to leave the village even to attend elementary school. Timber royalties also helped pay for the small diesel vessel that carried people and goods back and forth along the mountainous coast, which lacked an overland highway.

It was not until the 1990s that a Tok Ples (Vernacular) Skul was established in the village to teach basic literacy in the local language, before children went away to elementary school, where Tok Pisin was the lingua franca. I made a tiny contribution to getting it started by sending enough linguistic materials on Numbami to show that it had a workable orthography, which was a prerequisite for any Tok Ples Skul. But my work on the language was otherwise aimed at other linguists, for whom I hope eventually (after I retire) to finish a reference grammar of the language.

But my priorities shifted over the past year from language description to language documentation, thanks to new technologies and new relationships. One factor was the new language documentation software mentioned above. The other was making new contacts via Facebook with well-educated grandchildren of my host father who have mastered English and Tok Pisin well, but know very little Numbami. They are my new target audience, not linguists and not people in the village who still speak the language (to the extent they do).

Numbami is the village language of only one village on the face of the earth. In the 1970s, that village had fewer than 300 people, and even there more people spoke Tok Pisin than Numbami. If the elders had to write, they wrote in Jabêm, the Lutheran mission lingua franca in which all but one old lady had been educated. My host father was educated in Jabêm schools, had taught in them, was an acknowledged authority on the language, and managed to get me interested enough to make Jabêm the standard of reference for much of my analysis of Numbami. (Many years later, I sidelined my Numbami reference grammar to translate Otto Dempwolff‘s grammar of Jabêm after I met by chance online a potential cotranslator in Romania whose German was much better than mine.)

The first paper I published after returning from my fieldwork in Papua New Guinea was on multilingualism and language mixture among the Numbami. If village residents want to find spouses they’re not related to, they generally have to marry someone from a different language group. Unless both spouse and children live in the village, they don’t learn more than the rudiments of the village language. The kids grow up speaking Tok Pisin, in any case. If they pursue education and job opportunities in town, they learn English, too.

Nothing I can do will affect language use in the Numbami village. If people end up abandoning that language in favor of others more useful, I can’t blame them. Villagers have been shifting language loyalties throughout the human history of New Guinea, for all sorts of reasons. The articles I’ve published so far are of little use to anyone except other linguists. But the dictionary I’m now editing may be useful both to a few linguists and to a few educated, town-dwelling people of partial Numbami heritage who want to learn more about their lost ancestral language, but who are accustomed to learning through the medium of English. Finally, the narrative texts may also be of at least historical interest to a third tiny audience of people who learned to speak Numbami in the village and to read it in the Tok Ples Skul.

Alien Encounter at Mercury Bay, 1769

From: Blue Latitudes: Boldly Going Where Captain Cook Has Gone Before, by Tony Horwitz (Picador, 2002), pp. 104-105:

Most scholars believe that sailing canoes set off from the Society Isles, or the nearby Cook Islands, between A.D. 800 and 1200, carrying pioneers as well as plants and animals. They landed on the unpopulated North Island and gradually spread out, making New Zealand the last major landmass on earth to be settled. Then, nothing—until Cook arrived, the first intruder on the North Island since roughly the time of the Crusades.

To me, this was the most extraordinary and enviable facet of Cook’s travels: the moment of first contact between the “discoverer” and the “discovered.” No matter how far a man traveled today, he couldn’t hope to reach a land and society as untouched by the West as the North Island was in 1769. Cook, at least, anticipated first contact; finding new lands and peoples was part of his job description. For those he encountered, the moment of European arrival must have been so strange as to defy modern comprehension. The only experience that might resemble it today would be to find an alien spacecraft touching down in your backyard—except that Hollywood has prepared us even for that. Pacific islanders had no basis for so much as imagining a tall-masted ship, much less one from the other end of the globe carrying white men speaking an unfamiliar tongue.

According to stories told long after Cook’s arrival in New Zealand, some natives thought the ship’s billowing sails were the wings of a giant bird. Others saw three trees sprouting from the vessel’s base and guessed it was a floating island. A much fuller account survives from Mercury Bay, up the coast from Cook’s first landfall, where the Endeavour visited a month later. A boy about the same age as Young Nick, named Te Horeta, stood watching the ship’s approach from shore and lived long enough to share his memory with colonists, several of whom recorded his words. Te Horeta’s vivid and poetic detail, corroborated by the journals of Cook and his men, makes his story one of the most remarkable accounts in the annals of exploration.

“In the days long past,” Te Horeta recalled, he went with his clan to gather oysters and cockles beside a calm bay known by the name Gentle as a Young Girl. One day, an apparition appeared on the water, a vessel much larger than any canoe Te Horeta had ever seen. Watching from the beach, the clan’s elders wondered if the ship had come from the spirit world. Then pale creatures climbed from the vessel and paddled small craft toward shore, with their backs to the land. At this, the clan’s aged men nodded and said, “Yes, it is so: these people are goblins; their eyes are at the back of their heads.” Te Horeta fled into the forest with the other children, leaving the clan’s warriors on the beach.

At first, the goblins did no harm. They gathered oysters and other food. One collected shells, flowers, and tree blossoms, and knocked on stones, putting them in bags. Curious, the children crept out of the woods. “We stroked their garments,” Te Horeta recalled, “and we were pleased by the whiteness of their skin, and the blue eyes of some of them.” The goblins offered food from their ship: hard, dry lumps that looked like pumice stones, and fatty meat so salty that even the warriors winced. Was it whale’s flesh? A man’s? One goblin pointed his walking stick in the air. “Thunder was heard to crash and a flash of lightning was seen,” Te Horeta said. Then a bird fell to the ground. “But what had killed it?” Later, a warrior offered to trade with the newcomers, then snatched a goblin’s cloth and paddled away without surrendering his own dogskin cloak. A walking stick flashed and the warrior fell with a hole in his back. The clan buried him in the goblin’s garment; because the warrior had caused his own death, there was no utu, no revenge. The site of his killing became known by the name A Warm Bad Day.

Cook’s Endeavour: Victualled, Flogged, & Pickled

From: Blue Latitudes: Boldly Going Where Captain Cook Has Gone Before, by Tony Horwitz (Picador, 2002), pp. 16-17, 28-29:

ON MY FIRST night aboard the replica Endeavour, I sat down with my watchmates to a dinner advertised on galley blackboard as “gruel.” This turned out to be a tasty stew, with pie and fruit to follow It was also a marked improvement on the fare aboard the original Endeavour. Before leaving port. Cook complained to the Navy Board that the cook assigned his ship was “a lame infirm man, and incapable of doing his Duty.” The board granted his request for a replacement sending John Thompson, who had lost his right hand. Cook’s request for still another man was denied. The Navy gave preference to cripples and maimed persons” in its appointment of cooks, a fair indicator of its regard for sailors’ palates.

“Victualled” for twelve months, the Endeavour toted thousands of pounds of ship’s biscuit (hardtack), salt beef, and salt pork: the sailors staples. On alternate days, the crew ate oatmeal and cheese instead of meat. Though hearty—a daily ration packed 4,500 calories—the sailors’ diet was as foul as it was monotonous. “Our bread indeed is but indifferent,” the Endeavour‘s botanist, Joseph Banks, observed, “occasioned by the quantity of Vermin that are in it. I have often seen hundreds nay thousands shaken out of a single bisket.” Banks catalogued five types of insect and noted their mustardy and “very disagreeable” flavor, which he likened to a medicinal tonic made from stags’ horns.

On the replica, we also enjoyed a considerable luxury denied Cook’s men: marine toilets and showers tucked discreetly in the forward hold. Up on the main deck, Todd showed us what the original sailors used: holed planks extending from the bow, utterly exposed in every sense. These were called heads, or seats of ease. On Cook’s second voyage, an unfortunate sailor was last seen using the heads, from which he fell and drowned….

On our first-day tour of the replica, Todd had showed us a canvas bag; inside it was a heavy knotted rope—the cat-o’-nine-tails, so named for the number of its cords and the catlike scratches it left on a man’s back. This was also the origin of the phrases “let the cat out of the bag” and “not enough room to swing a cat.” The cat came out of the bag with depressing regularity during the Endeavour‘s long passage to the Pacific. On one day alone, three men were lashed, the last for “not doing his duty in punishing the above two.” Before the trip was over. Cook would flog one in four of his crew, about average for eighteenth-century voyages.

If Cook didn’t spare the lash, he also didn’t stint sailors their most treasured salve: alcohol. The Endeavour sailed with a staggering quantity of booze: 1,200 gallons of beer, 1,600 gallons of spirits (brandy, arrack, rum), and 3,032 gallons of wine that Cook collected at Madeira. The customary ration for a sailor was a gallon of beer a day, or a pint of spirits, diluted with water to make a twice-daily dose of “grog.” Sailors also mixed beer with rum or brandy to create the debilitating drink known as flip. Cook’s notes on individual crewmen include frequent asides such as “more or less drunk every day.”

Guam: New Predator, New Prey

From Out of Eden: An Odyssey of Ecological Invasion, by Alan Burdick (Farrar, Straus and Giroux, 2005), p. 31:

In simple ecological models, the relationship between a predator and its prey is straightforward, Malthusian. In the classic model, there are rabbits and there are lynxes eating rabbits: the lynxes thrive, reproduce, spawn more hungry lynxes—so many that soon there are fewer and fewer rabbits, fewer lynx meals, eventually fewer lynxes. The lynx population declines, the rabbits slowly recover their numbers, and the cycle of eating and eaten, supply and starvation, begins again. The situation on Guam is altogether different. Even after the forests were emptied of birds, the snake continued to thrive. Its numbers are down: approximately twenty-four snakes per hectare, from a hundred per hectare in the late 1980s. That is a major drop, yet twenty-four snakes per hectare is still four times more dense than even the most snake-infested plot of Amazon jungle. Campbell said, “That’s like having a gob versus a big gob.” Now the snakes subsist on skinks and geckos. And the skinks and geckos are not disappearing. In fact, because they are no longer preyed upon by birds, they are more abundant than ever. The snakes have found a renewable resource, the gustatory equivalent of solar energy. And there is evidence to suggest that the snakes are reproducing faster too, giving birth at a younger age. Few biological invaders, once they have gained such a solid foothold in their new habitat, subsequently disappear from it entirely. Any hope that the snake would eat itself out of existence appears equally groundless.

In On the Origin of Species, Darwin meditated on the impact that house cats might be having on the surrounding countryside. If there were more cats, there would be fewer mice. With fewer mice burrowing into the hives of their favorite snack, the bumblebee, there would perforce be more bees buzzing about, gathering nectar, pollinating the local blossoms—most notably the blossoms of Trifolium pratense, the common red clover, which depends exclusively on the bumblebee to complete its reproductive cycle. In short, more cats would mean more red clover. “Plants and animals, most remote in the scale of nature, are bound together by a web of complex relations,” Darwin wrote.

The Zen of Ecological Niches

From Out of Eden: An Odyssey of Ecological Invasion, by Alan Burdick (Farrar, Straus and Giroux, 2005), pp. 135-136:

For Charles Elton and many of his successors, biological invasions were a way to probe and characterize the way that ecological communities are assembled and held together. The ecosystem was studied as a sort of organic machine—a system—of semi-interchangeable parts, or, to borrow another analogy, a kind of corporate economy maintained by organisms with defined ecological jobs. By studying the arrival of foreign workers and the consequent displacements, the notion went, a scientist could figure out the overall corporate structure: the various job descriptions, the interoffice competition, the company bylaws, the glue of market success and longevity. Critical to this schema is the job itself, the ecological niche—a concept that has receded from meaning over the years with every new attempt to clarify it. Today, one can speak of a habitat niche (the range of habitats in which a species can and does occur) or a functional niche, the “role” or “place” of a species in a community—a notion further divisible into trophic niche (the relationship of the species to its food and enemies) and resource niche (which spans things utilized by the species, like nesting sites). As a conceptual tool, the niche has effectively dropped from the modern ecologist’s belt. “Niche,” Mark Williamson summarizes in his book Biological Invasions, “is useful in a preliminary, exploratory description, but becomes difficult to pin down in particular situations.”

Whatever a niche is exactly, successful invasion, in Elton’s schema, allegedly involves occupying an empty one. But, many biologists counter. what does it mean for a niche to lie “empty”? If a niche is an ecological job that takes up food or resources, and such a job is going unfilled in an ecosystem, the community would show side effects; it would soon be overwhelmed by waste or unused food. So for such a job opening to exist yet not harm the community, by definition it must be a job that involves no interaction whatsoever with other community members—like one of those jobs the boss’s kid fills on summer vacation, only less productive. But if that is the case. any invader entering this empty non-job would have no impact on the system—which clearly isn’t what happens with many invaders. “If you take the view that there are no empty niches,” Williamson writes, “the invasion of communities cannot involve occupying empty niches,” Some ecologists contend that in saving that an invader occupies a vacant niche, what is meant is that an invader plays a new functional role in the community, not that it doesn’t use resources previously used by other species. The brown tree snake fits this definition; in coming to Guam, it declared itself top predator of an ecosystem that for eons had run perfectly well without such a top executive. Under these terms, Williamson writes, successful invasion becomes a matter of always, often, or sometimes entering a niche that can be full, empty, partly full, or partly empty—terminology that begins to suit the term itself. Williamson concludes, “It is to some extent a matter or the meaning you want to put on the word ’empty.'”

At the very least, invasion biology has made it clear that the conflicts and interactions that transpire between species in an ecosystem are too fluid and dynamic to be meaningfully described by a static term like niche. To introduce niche theory is to propose a koan: Does an ecological niche exist before on invader arrives to fill it? Meditatively interesting, perhaps, but useless in forecasting. “We are still unable to recognize a vacant niche except by carrying out the tautological experiment of introducing a species and seeing if it becomes established,” one biologist notes. Williamson adds, “The extent to which a niche is vacant is, in practice, a post hoc explanation. Post hoc explanations are neither intellectually satisfying nor much use in prediction.”

This book is engagingly written, but contains a lot of little factual errors.

Blogging Sabbatical

I began blogging six years ago this month, in December 2003. Since then, I’ve published over 2,000 blogposts, most of them excerpts from books I was reading. But the number of posts has declined each year—from over 550 in 2004 to under 200 in 2009—as I’ve become involved in a greater variety of online publishing hobbies.

In the spring of 2006, I bought my first digital camera (a little point-and-shoot Olympus), took it with me on a 4-month sabbatical spell in Japan, and soon began building a portfolio of documentary—rather than artistic—photos on Flickr, some of them scans of old photos from my earlier travels. This month I got my third digital camera (a Canon Powershot) and my Flickr portfolio numbers almost 2,500 images. This year I had to replace my trusty old HP flatbed scanner, orphaned by Vista, with a new Canon that I am quite happy with. (A local middle school is now making use of my orphaned scanner and ancient workhorse of a printer—an HP 5MP Laserjet.)

Early in 2009, I discovered major photographic lacunae that I could easily fill in Wikipedia’s coverage of sites on the National Register of Historic Places in Hawai‘i and began a campaign to photograph as many as I could and upload them to Wikimedia Commons, then add the images to the articles. Now I’m rather heavily involved in WikiProject Hawaii and WikiProject NRHP, both as a photographer and an writer/editor.

These online documentation projects have convinced me to put this blog on the back burner in 2010 in order to concentrate on a long-term language documentation project I need to finish: a comprehensive grammatical description of Numbami, the once almost entirely undocumented language whose speakers were my gracious hosts during fieldwork in Papua New Guinea in 1976. I have completed and published many bits and pieces about the language over the intervening years but need to put them all together and fill in many gaps. Unlike other projects described above, it’s more a duty than a hobby—a daunting one, but not unpleasant to contemplate.

Among the Spice Island Sago-eaters

From The Spice Islands Voyage: The Quest for Alfred Wallace, the Man Who Shared Darwin’s Discovery of Evolution, by Tim Severin (Carroll & Graf, 1997), pp. 142-144:

More than a century before Wallace‘s visit, the people of Gorong were still habitual sago-eaters. Toman upon toman of sago flour was stacked up in the little shops of Kataloko. The tomans were the shape of small solid drums wrapped in green palm leaves, or you could buy the sago flour already baked into biscuits and neatly tied with string into bundles of ten. Then they looked exactly like small, hard, light brown floor-tiles. When we asked where all this sago came from, we were told it came from the island opposite, from Pasang where the sago palms [Metroxlon sagu] still grew.

Pasang had a deceptive approach. From the direction we arrived with [our boat] Alfred Wallace, it looked as if the usual fringing coral reef protected a broad lagoon with deeper water; if we could cross the reef and enter the lagoon we would be safe. At least, that is how it appeared, because the water was much darker on the landward side of the reef. In fact, when we crossed the reef we found that we were wrong. The lagoon was dark not because it was deep, but because it was carpeted with brown sea grass. In fact it was barely 50 centimetres deep and studded with rocks. A normal vessel would have been stuck fast, but again Alfred Wallace needed so little water to float that we could pole our way through the shallows for a kilometre or more until we were able to anchor off the main village of the island. From there a guide took us into the sago swamps.

The sago palms appeared to be wild, but were in fact planted as seedlings in the muck and stagnant pools of the swamp. For 12–15 years the palm tree grew until its trunk was approximately one metre thick. Then, quite suddenly, the tree flowered and was ready to harvest. The owner felled the tree, peeled off the skin and chopped his way into the thick white soft trunk. We found a sago harvester at work, sitting inside the tree-trunk as if in a large dugout canoe. In front of him was the unworked face of white sago pith, and he was steadily hacking at it with a long handle which had a tiny sharp metal blade set at right-angles in the end. As he struck, the blade sliced away a sliver of sago pith which fell inside the hollow trunk and on to his feet. The blade also came alarmingly close to his feet with each blow, and it seemed he risked chopping off his toes. Occasionally he wriggled his feet and toes, pushing the growing pile of the sago shavings back down the hollow tree-trunk. When he was tired of chopping, he climbed out of the tree-trunk, filled a sack with sago shavings and carried them off through the squelching mud to a trough which he had set up beside a pool of stagnant swamp water. He dumped the shavings into the upper end of the trough, poured water over them from a bucket, and squeezed the wet pith against a cloth strainer. The water ran out of the sago pith as white as milk, carrying sago flour with it, and drained away into another trough where it was allowed to settle. Within an hour, a thick deposit of pure white edible sago flour had settled in the trough and could be scooped out with the hands. It was ready to bake and eat.

The sago gatherer claimed that in just two days’ work he could produce enough food to feed his family for a month. As for the sago palm, he said, once you had planted the seedling there was no more work involved. You merely had to let it grow. Apart from Joe, who rather liked the taste of sago biscuit, the rest of us wondered if it was even worth that much effort. We compared eating sago with buying a packet of breakfast cereal, throwing away the contents and eating the cardboard packet.

I got to help process a sago palm into starch during my fieldwork in Papua New Guinea in 1976. As unskilled labor, my job was to pound the pith of the felled sago palm trunk into smithereens, using an adze handle with an artillery shell casing on the end. Others carried the pith to the washing chutes near the river where the starch was strained out of the pulp, then drained and formed into large blocks, which were allotted among the households whose members helped with the work. I had never heard the term toman used to name such blocks until I read this book.
