the market can be improved in three ways: (1) To do away with the 

 marketing of tf soaked " scallops by the co-operation of the dealers 

 and the payment of a proportional increase in price per gallon for 

 "dry"' scallops from the fisherman. (2) Co-operation between com- 

 mission merchants and scallopers, which would result in better satisfac- 

 tion in both goods and prices, and do away to some extent with that 

 great bugbear, " uncertainty of returns," which is so discouraging to 

 the fisherman and makes the fishery a lottery. (3) To increase the 

 popular demand for scallops by wider fields through the transportation 

 facilities and advertising. 



The methods of capture will slowly improve. No suggestions can be 

 offered here for improvements in dredges, etc., as each locality has con- 

 ditions peculiar to itself. The description of the different styles of 

 dredges in the various localities may cause innovations in certain sec- 

 tions which have fallen in that rut of custom so prevalent in our fishing 

 towns. During the last few years the gasolene dredger has gradually 

 replaced the sail, and while dredging with sail will probably remain, it 

 will be in combination with power, as in power catboats, resulting in a 

 partial revolution in scalloping methods. 



The question of just and fair laws has been an important factor in 

 the fishery. While in the past all laws have not met this standard, the 

 tendency at the present time and for the future is improvement in sim- 

 plicity and justice, with the sole aim of preserving the fishery, serving 

 the consumer and protecting the fisherman. 



CHAPTER VII METHODS OF INVESTIGATION 



Owing to the different classes of readers, and with a desire to pre- 

 sent the material so that it will be intelligible to all, it has seemed 

 best to " cull " from the main portions of the report the various 

 methods, tables, etc., which were used in its preparation, and to incor- 

 porate them in a reference chapter, where, though accessible, they 

 will not interfere with the continuity of the narrative. In this way 

 the report is made more interesting to the fishermen and general pub- 

 lic, without detracting from its scientific value. Throughout the paper 

 constant reference is made to the contents of this chapter, for the 

 purpose of avoiding repetition and unnecessary description. 



The chapter is mainly divided into: (1) methods used in obtain- 

 ing the early embryology and life history; (2) methods of conducting 

 the growth experiments; (3) tables; (4) glossary; and (5) bibliog- 

 raphy. 



Embryological Methods. 



It is hardly necessary to describe in detail the general method of 

 investigation of the early life history of the scallop. It is sufficient to 

 state that the usual methods of microscopic study, camera lucida
