80 FISH AND GAME. 



1. A report upon the life history, growth and culture of the soft clam 

 (M ya arenaria) . 



2. The food of the economic lamellibranchiata mollusks, including a 

 brief study of the value of certain Massachusetts waters for the production 

 of shellfish. 



3. A shellfish compend, which gives briefly the practical problems of 

 quahaug, clam, scallop and oyster culture. 



4. The fresh-water ponds of Massachusetts, their natural conditions 

 for the sustenance of fish life, their possibilities of development, and their 

 adaptability for stocking with food and game fish. 



5. The trout brooks of Massachusetts, including a brief description of 

 the more important water systems of the Commonwealth, with a plan for 

 systematic stocking and development of their latent and decadent pos- 

 sibilities for food production. 



6. The fisheries of Buzzards Bay, presenting various information con- 

 cerning the methods of increasing the supply of food fish, with special 

 emphasis upon trap fishing as a basis for subsequent legislation. 



7. The Massachusetts alewife fisheries, their decline, present condition, 

 and a proposed plan for re-establishment. 



8. The diseases of game birds, comprising observations upon various 

 types of infections in Massachusetts birds. 



Assistants. Roy S. Corwin of Williams College served as an efficient 

 assistant biologist for the years 1912 and 1913, devoting his entire time to 

 biological work, with the exception of two months, January and February, 

 1913, when he was engaged in fish culture wcrk at the Sandwich hatchery. 

 During the summer of 1912 the temporary assistants were William G. 

 Vinal and Howard Reynolds of Harvard College, and George F. Hopkins 

 cf Bridgewater Normal School. These men were principally engaged in 

 the examination of the fresh-water ponds of the Commonwealth. In 1913 

 the temporary assistants were William G. Vinal, George F. Hopkins and 

 Capt. Clifton Eldridge of Harwichport. The cliief work for the summer 

 of 1913 was an investigation of the fisheries of Buzzards Bay. Arthur B. 

 Merriam of Boston University, under the immediate direction of the 

 biologist, conducted an investigation of bird diseases at the Sutton hatch- 

 ery. In 1914 Leslie J. Gilbride of Boston acted as temporary assistant. 

 The employment of the temporary assistants continued only for the months 

 of June, July and August, since the majority .of these men were teachers. 

 With the exception of the services of Mr. Corwin, up to Jan. 1, 1914, for 

 the past three years the biologist has conducted the work alone during the 

 greater part of the year, only obtaining assistants during the summer 

 season, when field work was in progress. I wish to express my sincere 

 appreciation of the earnest and helpful efforts of all assistants, and 

 especially to Mr. Corwin for his careful and industrious work upon the 

 ponds and alewife fishery. 



Laboratories. During 1912 the Wellfleet laboratory was the head- 

 quarters for the pond and mollusk work. The men in the field shipped
