lobster had entered, these nets had to be constantly watched, the lobster being in the habit of retiring after he had finished his repast. In using these the fisherman would generally go out in the evening and at short intervals he would haul in his nets and remove whatever lobsters they might contain. The constant attention necessary in attending to these hoop nets led the fishermen to devise an apparatus which would hold the lobsters after once entering and would require only occasional visits, and "lath pots" were found to fulfill all requirements. They acquire the name from the use of common laths in their construction. They are usually about 4 feet in length, with a width of about 2 feet, a height of 18 inches, and in Maine are usually of semicylindrical form.

The following description of this apparatus is from the Fishery Industries of the United States, sec. v, vol. 11, p. 666:

The framework of the bottom consists of three strips of wood, either hemlock, spruce, or pine (the first mentioned being the most durable), a little longer than the width of the pot, about 2¾ inches wide and 1 inch thick. In the ends of each of the outer strips a hole is bored to receive the ends of a small branch of pliable wood, which is bent into a regular semicircular curve. These hoops are made of branches of spruce or hemlock, or of hardwood saplings, such as maple, birch, or ash, generally retaining the bark. Three of these similar frames, straight below and curved above, constitute the framework of each pot, one to stand at each end and one in the center. The narrow strips of wood, generally ordinary house laths of spruce or pine, which form the covering, are nailed lengthwise to them, with interspaces between about equal to the width of the lathe. On the bottom the laths are sometimes nailed on the outside and sometimes on the inside of the cross pieces. The door is formed by three or four of the laths running the entire length near the top. The door is hinged on by means of small leather strips, and is fastened by a single wooden button in the center, or by two buttons, one at each end. The openings into the pot … are two in number, one at each end, are generally knit of coarse twine and have a mesh between three-fourths of an inch and 1 inch square. They are funnel-shaped, with one side shorter than the other, and at the larger end have the same diameter as the framework. The smaller and inner end measures about 6 inches in diameter and is held open by means of a wire ring or wooden hoop. The funnels are fastened by the larger ends to the end frames of the pot, with the shorter side uppermost, so that when they are in place they lead obliquely upward into the pot instead of horizontally. The inner ends are secured in position by one or two cords extending to the center frame. The funnels are about 11 or 12 inches deep, and therefore extend about halfway to the center of the pot. They taper rapidly and form a strongly inclined plane, up which the lobsters must climb in their search for the bait. A two-strand manila twine is most commonly used for the funnels. Cotton is also used, but is more expensive and less durable.

Lobster pots

A change in the shape of the funnel was first made at Matinicus shortly before 1890. This has been called the "patent head." Large lobsters are said to always go to the top and small ones to the bottom of the pots. By going to the top in the "old-head" pot large lobsters made their escape through the hole, but in the pots with "patent heads" instead of finding their way through the hole the big lobsters slide over it. The "patent head" has not been used to any extent, however. The sketch shown on the following page gives a good idea of the difference in shape.

Old style of head (in general use)	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 7½ 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.

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.

In the warm season the pots are frequently set on trawls or "ground lines," as lobsters are quite thick then on the rocky bottom near shore. If the bottom is sandy they are set farther from shore. Lobsters are most numerous on a rocky bottom. In the trawl method the pots are usually set about 30 feet apart, depending on the depth of water, so that when one pot is in the boat the next will be on the bottom. The ground lines have large anchors at each end and a floating buoy tied to a strong line, which is fastened to the ground line almost 25 fathoms from the anchors. When the last pot is hauled the anchor is far enough away to hold the boat in position. The pots are set at distances from the shore ranging
