Mr. N. R. Buller, of Pennsylvania: I would like to inquire in this con- 

 nection whether the increase of Daphnia in ponds in which this meal is 

 scattered is not simply because the meal acts as a fertilizer. My impression 

 is that the Daphnia feed on algae. In other words doesn't this meal simply 

 furnish ammonia and ammonium nitrate which could be as easily and more 

 cheaply furnished by commercial fertilizers? Doesn't it act only as a 

 fertilizer? 



Mr. Lydell: That may be true. It is up to some one better versed in 

 science than I am and I only know the results we obtained. In regard to the 

 trouble experienced in feeding the clams to bass, I may say that if the whole 

 clam is scalded and ground, you do not get the worm-like masses. The feet 

 of the mussels are very hard and do not soften readily. By being pulverized 

 in the dry condition and then soaked, that part is prepared so the fish will 

 eat and relish it. An eighth of a teaspoonful of this finest meal put in a cup 

 of hot water will make as fine a bouillon as you ever drank. 



Mr. Killian, of Maryland: There is a preparation being manufactured 

 from oysters at Hampton, Va., and sold under medical recommendation as 

 human food. It is the very same proposition.
