The dealers cars are very similar to those used by the fishermen, only much larger. They generally average about 30 feet in length, 12 feet in width; and 3 feet in depth, with capacity for from 2,000 to 3,000 lobsters. The inner part of this car is usually divided off into five transverse compartments by means of a framework inside. Each compartment is provided with two large doors entering from the top, one door on each side of the middle line of the car. These cars cost the dealers about $70 each. The life of one of these cars is about five or six years, although at the end of about three years it is generally necessary to replace the sides of the car on account of the ravages of a dock worm which is quite abundant along the Maine coast. When new the top of the car is usually about a foot above the water, but as it gets water-soaked it sinks down until it is even with the water, and some of the older cars have to be buoyed up with kegs at each end, placed inside, to prevent them from sinking below the surface. These cars are moored alongside the docks of the dealers at Portland and Rockland and other points. [Illustration: Lobster cars used in the wholesale trade at Portland] Mr. J. R. Burns, of Friendship, has invented and patented a new style of car. The inside is divided into a series of compartments by horizontal and vertical partitions of slats, wire netting, or any material which will permit the free circulation of the water. Each compartment has a chute extending down into it from the top, by means of which the lobsters can be put in and their food given them. There are also conveniently arranged openings, with doors, through which the lobsters may be removed when desired. These cars usually average about 35 feet in length, 18 feet in width, and 6 feet in depth, and have a capacity for about 5,000 lobsters each. They are in use at Rockland, Friendship, Tremont, and Jonesport. They prevent the lobsters from huddling together and thus killing each other by their own weight. METHODS OF SHIPPING, WHOLESALE TRADE, ETC. As lobsters can not be shipped or preserved in a frozen state they must be shipped either alive or boiled. About nine-tenths of the lobsters caught in Maine waters are shipped in the live state. The principal shipping centers are Portland, Rockland, and Eastport, which have good railroad and steamship facilities with points outside of the State. Those shipped from the latter point are mainly from the British Provinces, the fishermen near Eastport bringing them in in their own boats. A number also come in from the Provinces on the regular steamship lines. The other places get their supply from the smacks and also from the fishermen in their vicinity, who run in their own catch. Portland is very favorably situated in this regard, as Casco Bay is a noted fishing center for lobsters.
