Not the least interesting of the American pearl fisheries is that which has the abalones (Haliotis) for its object. These occur in many inshore tropical and semi-tropical waters, and particularly in the marginal waters of the Pacific. They attach themselves to the rocks by means of their large muscular disk-shaped foot, which acts like a sucker or an exhaust-cup.
On the California coast the abalones are gathered in large quantities for the pearls, for the shells, and especially for the flesh, which is dried and used for food. The principal fishing grounds are at Point Lobos in Monterey County, and along the shores of Catalina and Santa Rosa islands in Santa Barbara County, with smaller quantities from Halfmoon Bay and from the rocks along the shores of Mendocino County. At low tide the fishermen wade out in shallow water, and, by means of a knife, separate the mollusk from its resting-place. Unless this is done quickly and before the mollusk has time to prepare itself for the attack, it closes down on the rock by means of its sucker-like foot, from which it cannot be removed without breaking the shell. A story is told at Santa Barbara of a Chinese fisherman having been drowned off one of the outer islands by having his hand caught underneath the shell of an abalone.
A few years ago, Japanese fishermen introduced the use of diving-suits in taking these mollusks in three fathoms of water; but in March, 1907, the California legislature interdicted this form of fishery. That legislature also interdicted the capture of black abalones measuring “less than twelve inches around the outer edge of the shell, or any other abalone, the shell of which shall measure less than fifteen inches around the outer edge.”
The animal is removed from the shell by thrusting a thin blade of soft steel between the flesh and the shell, and thus loosening the great muscle. The flesh is salted and boiled, and then strung on long rods to dry in the open air. When properly cured, the pieces are almost as hard and stiff as sole leather. Most of it is packed in sacks and exported to China, but large quantities are sold on the Pacific coast at from five to ten cents per pound. The catch is much less than it was forty years ago.
SHELL OF PEARL-BEARING ABALONE
From the coast of California
Many pearly masses are obtained from the abalones, and a few of these are of considerable beauty. Some are very large, measuring two inches in length and half an inch or more in width; but they are rarely of good form, and their value is commonly far less than that of choice Oriental pearls. Owing to their irregularity in form, they are scarcely suitable for necklaces. One of the best necklaces of these pearls ever brought together sold a few years ago for $2000; but individual specimens have exceeded $1000 in market value. While abalone pearls are not on the market in any great quantities, one resident of Santa Barbara has a collection of more than a thousand specimens, ranging in value from several hundred dollars to less than one dollar each. Most of the objects sold in curio and jewelry stores on the Pacific coast as abalone pearls are simply irregular knots or protuberances cut from the surface of the shell. The California fishermen are credited with having received $3000 for the abalone pearls in 1904; but it is safe to say that this represents only a small fraction of their final sale value.
In the river mussels of Canada, and especially in those from the Province of Quebec, and the Ungava Region, pearls are occasionally found. These are usually white and of good luster. They are not the object of systematic search, but in the aggregate many are secured by Indians and Eskimos, and some by the trappers and fishermen who operate from Quebec and Montreal. A number, weighing from one to sixty-five grains each, were shown at the Colonial Exhibition in London in 1886, and received favorable notice. Recently, two beautifully matched pink pearls, weighing about fourteen grains each, were obtained from one mussel. A single pearl found in Canada has sold for $1000, but as a general rule they are of relatively little value. The Hudson Bay traders are represented as having secured a fair share of these pearls.
During the last few years, many pearls have been found in the streams of Prince Edward Island and of New Brunswick Province, and also in those of Nova Scotia. Most of them are well formed, but their color is generally inferior and their luster deficient. Many of them are buff or brown in color, some are bright and fairly good, a few are rose-tinted, and others are slate-colored and even almost black. Toronto jewelers report that many Canadian pearls are in the possession of farmers and others in the lower provinces, held by them for higher prices than the jewelers are willing to pay. The Nova Scotia pearls are from a bivalve which has been identified as Alasmodon margaritifera. They are especially abundant in Annapolis and King counties.
Even in the streams of northern Labrador and of the Caniapuscaw watershed, pearls are obtained by the natives, and by the hunters and fishermen who resort to that desolate country. These closely resemble the pearls of Scotland in color, size, and luster. A story is told of a fisherman who by chance found in one shell two well-matched pearls, which he later sold for $150; so pleased was he with his success that he spent a fortnight in diligent search, but secured only half a dozen small ones, worth perhaps $3 for the lot. Most of these pearls are silvery white, but beautiful pink ones are not rare. An unusually choice 20–grain pearl from this region sold in 1905 for $1000.
