The smacks and dealers buy lobsters by count, as the fishermen generally have no facilities for weighing them; but the dealers always sell by weight. The mortality among the lobsters from the time they are put aboard the smacks until they are barreled for shipment is estimated at about 5 per cent. BOILING. Live lobsters are much preferred by the trade throughout the country, and only those that can not be marketed in such condition are boiled. The number boiled fluctuates considerably, owing to the condition of the markets. When the fresh markets of Boston and New York are overstocked, the lobster dealers of Rockland and Portland, where most of the Maine lobsters are boiled, proceed to boil their surplus stock. The following description of the boiling is from The Fisheries and Fishery Industries of the United States, section v, vol. II, p. 684: The boilers are rectangular wooden tanks or vats of about 60 gallons capacity, lined with zinc and furnished with a cover. Heat is applied by the introduction of steam through a series of perforated pipes arranged in the bottom of the tank. The steam is generated in an ordinary boiler standing close at hand. The lobsters are not thrown directly into the vat, as the operation of removing them after cooking would in such an event be an exceedingly tedious one; but an iron framework basket, of rather slender bars is made to fit the tank loosely, and is lowered and raised by means of a small derrick placed over the tank. This frame, which holds about 300 pounds, is filled with lobsters at the edge of the wharf from the floating cars, and is then carried to the tank and lowered into it after the water it contains has reached the desired temperature, that of boiling. The water is first supplied to the tank, which is filled to about one-third or two-thirds its capacity, about a peck of salt is added, and then the steam is turned on. The same water suffices for several successive boilings, about 2 quarts of salt being added each time. The lobsters are allowed to remain in about half an hour, or until the proper red color indicates they are sufficiently cooked. [Illustration: Boiling live lobsters preparatory to shipping on ice, showing boiler, steam tank, cage, etc.] After cooling, they are packed in barrels for shipment, just as live lobsters are. When well iced they will keep a week or longer. Only live lobsters are boiled, as the meat of those which die prior to boiling deteriorates rapidly.
