Scallop Dredge,--"The Scraper."--This implement has the form of a triangular iron framework, with a curve of nearly 90o atthe base, to form the bowl of the dredge. On the upper side a raised crossbar connects the two arms, while at the bottom a strip of iron 2 inches wide extends across the dredge. This narrow strip acts as a scraping blade, and is set at an angle so as to dig into the soil. The top of the net is fastened to the crossbar and the lower part to the blade. The usual dimensions of the dredge are: arms, 2 1/2 feet; upper crossbar, 2 feet; blade, 2 1/2 feet. The net varies in size, usually running from 2 to 3 feet in length and holding between 1 and 2 bushels. Additional weights can be put on the crossbar when the scalloper desires the dredge to "scrape" deeper. A wooden bar 2 feet long buoys the net. The scraper used at Nantucket has the entire net made of twine, whereas in other localities the lower part consists of interwoven iron rings
Oyster spats at different short intervals after fixation.... The larval shell (prodissoconch) maintains the same size as long as it can be recognized in a spat. Larval shells of all spats maintain approximately the same size, no matter how large the spats grow. In all the figures the prodissoconch is shaded, the dissoconch only outlined. The spats soon become so large that a lower power objective has to be used in order to see the whole spat at once.
Yunnan-Guizhou Townships, 2000 Household size (A5:A4)
Sichuan-Chongqinh Townships, 2000 Household size
These two sizes illustrate the sti ulating effect on growth of current, which acts as a food carrier. In each bet quahaugs of the same size were planted and allowed to remain for three years. The larger quahaugs were planted in a box on the raft, where the circulation of water was good; the smaller in the southeastern corner of the Powder Hole, not 75 yards from the raft, in shallow water among thick eelgrass, which shut off all circulation.
1 millimeter in size, half buried in the sand. The animal is feeding, water passing in and out of the extended siphon, as shown by the arrows.

Bliss No. 1K Semi-Automatic Water Tester.--A machine for testing round or square cans from 1 1/2 to 6 3/4 inches in diamter by 1 1/2 to 6 inches in length, or the equivalent. Adapted for sanitary cans. It may also be arranged for larger work. Some of the different style cans, for the testing of which it is used, are shown in the illustration. The output, which depends on the size of can and the expertness of the operator, is from 4,000 to 10,000 cans a day.
Bliss No. 18 Automatic Double Seamer.--The operation of this machine, which is used for double seaming tops of filled cans, is entirely automatic. It is built to handle round, square, oval and oblong cans. In this machine the can stands perfectly still while being double seamed. The operator has only to place the filled cans with the tops on the feed table, where the jaws take the can and top, maingaining them in currect relation to each other. After double seaming, the can is carried away withoug futher manipulation on the part of the operator.
The machine has a capacity of 15 to 25 closures per minute, this varying according to the size and shape of the can to be double seamed. 3/4 sardine cans are handled at the rate of 20 per minute.
Scallops: Changes in form of shell. A series of drawings illustrating the changes from the early veliger (the first shell), which is 1/10 of a millimeter in size, to a 2-millimeter scallop. Note (a) change from flat-hinged veliger (1) to the prodissoconch (2), with prominent umbones; (b) return to a straight hinge (3), witdth greater than height; (c) width and height become equal (8); (d) formation of 'ears' (10)
