Kellogg, SpecialShell-hsh Commission. U. S. F. C. The Growth of the Soft Clam 305 In a U. S. Fish Commission report published in 1887,reference is made to an attempt at clam farming atBridgeport, Conn. It is stated that a beach right wassecured under a general state law, but that there was immense opposition from the shore people of the sub-urbs, who, as usual, bitterly and blindly opposed anycultivation of marine products. Small clams were planted by being placed in holesmade in sand, but this was found to be slow, and an at-tempt was made, by the use of all sorts of plows and cul-tivators, to plow the seed in. Finally a light plow wasinvented that was said to do the work bed, which was about half an acre in extent, was in-spected three years after the first planting, and showedan immense number of clams. As they were apparentlytoo thickly set, the
