VII. _Harvesting the Oysters._--The oysterman completes his planting about June 1. During the summer months, the growing period of the oyster, the grants remain idle except for the care and supervision of the oystermen. As the oyster takes from three to five years to attain its growth, the oysterman practically harvests but one-fourth to one-third of his entire stock each year, beginning about September 1 and continuing through the winter as the weather permits. In winter the oysterman, to keep up the market supply, beds "culled" oysters near the shore, where he can tong them through the ice whenever it is impossible to obtain oysters from his grant. The implements used in gathering the oyster harvest are of three kinds: tongs, dredges and rakes. Tongs are employed principally by the smaller oyster growers, and on ground where the water is comparatively shallow. A pair of tongs is really a pair of long-handled rakes, fastened together like a pair of shears. The pole, corresponding to the blade of the shears, varies from 8 to 16 feet in length. The rakes, some 2 to 2½ feet broad, are so fitted to the end of the poles that when extended by spreading the handles they rest upon the bottom parallel to each other. These tongs are usually worked from skiffs or flat-bottomed boats, the oystermen first separating the tips of the handles and then bringing them together, thus causing a corresponding movement of the two rakes, which with their 2-inch iron teeth gather in all the intervening oysters. The tongs with their burden of oysters are then lifted into the boat, emptied, and the process repeated. Dredging is a much faster and less laborious method of oystering than tonging, and can be carried on over a much larger territory. The oyster dredge consists of a bag of woven iron rings attached to an iron framework. From each corner of the framework iron rods extend, converging at a point some feet away. At this point the rope is attached, by which the dredge is dragged from either a sail or power boat. The blade, resting horizontally on the surface, is armed with teeth which rake the oysters into the bag. When this bag, which holds from 3 to 8 bushels, is full, the dredge is raised, usually by a windlass worked by steam, gasolene or hand power, as the case may be, its contents dumped out and the dredge lowered for another haul. Rakes, the third implement in general use, are not employed as extensively as tongs or dredges, but are used in still water, where the bottom is suitable.
