As has been said, the oyster industry in this district, while it has by no means attained its maximum development, has indeed reached very considerable proportions. The entire amount of area granted aggregates 810 acres. Of this total, some 510 acres are suitable for oyster culture, the remainder being soft mud, shifting sand, or otherwise unfit for utilization. The entire output for 1907 exceeded 38,000 bushels, valued at $26,250. Thirty-six men depend partially upon the business for a livelihood. Capital invested, $96,540 Power boats, 9 Value of power boats, $19,500 Dories and skiffs, 17 Value of dories and skiffs, $340 Implements:-- Dredges, 12 Tongs, 18 Value of implements, $2,000 Value of shore property, $6,200 Value of oysters on grant, $68,500 _Nantucket._ The oyster industry of Nantucket is of recent origin, and the oysters are as yet raised only for home consumption. Two grants have been leased by the selectmen, but only one of these is now planted. These grants are situated in the east and west bends of Polpis harbor. The cultivated grant in the west bend comprises some 20 acres, only 3 of which are of hard bottom and suitable for oyster culture, the remaining 17 having a soft mud bottom. The "seed" planted on the grant is obtained at New Haven. In the last few years the oysters on this grant have thrown a large quantity of spawn, which has caught on piles and stones at various places around Nantucket harbor. The only enemy to the Nantucket oyster is the oyster drill. The production of marketable oysters for 1906-07 was 200 bushels, valued at $400. These were sold for home trade on the island. One man is engaged in the oyster business for a period of three months each year. The oysters are taken both by dredging and with tongs.
