[Illustration: Old style of head (in general use) and "patent" head] In the center of the ordinary pot is a sort of spearhead of wood or iron from 8 to 12 inches long. This has one large barb and is set upright in the middle of the center frame. The bait is placed on this spearhead. Several large stones or bricks are lashed to the bottom of the pot, on the inside, in order to furnish weight enough to hold the pot at the bottom. As it was noticed that a lobster generally crawled over a pot before entering by the end, some pots of a square form and with the opening at the top were constructed, but they were not successful. Another variation had a length of 7-1/2 feet and five supporting frames inside instead of three, as in the old pot. These were set at equal distances apart, and had two more funnels than the other, one funnel being attached to each of the frames except the center one, and all pointing inward. In order to reach the bait the lobster had to pass through two funnels, and its chances of escape were thereby lessened. This style is rarely seen now. Still another variety in vogue for a short time had a trapdoor, on which the lobster had to climb in order to reach the bait; the door then gave way and precipitated the lobster into a secure inclosure. A few pots are made with a funnel of laths in place of the net funnels. They are the same as the ordinary pot in every other particular. The ordinary pots cost about $1 to construct. During certain seasons the pots are badly eaten by "worms," the shipworm (Teredo) or one of the species of small boring crustaceans. Pots are also frequently lost during stormy weather, and the fishermen therefore have a reserve stock on hand in order to replace those lost or temporarily disabled. METHODS OF FISHING. In fishing the traps are either set on single warps or on trawls of 8 to 40 and 50 pots. At first all pots were set singly. The line by which they were lowered and hauled up, and which also served as a buoy line, was fastened to one of the end frames of the bottom or sill, as it is called, at the intersection of the hoop. The buoys generally consist of a tapering piece of cedar or spruce, wedge-shaped, or nearly spindle shaped, and about 18 inches long. They are usually painted in distinctive colors, so that each fisherman may easily recognize his own. Small kegs are also used as buoys.
