The beef cost 12 cents a pound. Consequently the total cost of 

 the beef used in these experiments, 3,980 grams, was $1.05. 



The cost of the clams varied from $1.25 to $1.50 a bushel. The 

 average price may therefore be taken as about $1.35 per bushel. 

 The soft parts of a bushel of clams when cut out of the shell were found 

 to weigh about 4,830 grams. The 3,980 grams of ground clam fed 

 in the experiments, therefore, equals .824 bushel of clams in the 

 shell, and, at $1.35 a bushel, cost $1.11. To this must be added the 

 labor of cutting out the clams from the shell, an item of expense 

 which is not involved in using beef. Cutting out a bushel of average 

 size clams requires about two hours labor, which^ even at 15 cents 

 an hour, gives an additional expense of about 25 cents. So that the 

 total cost of the clam used in the experiment amounts to $1.35. 



In these experiments, therefore, the clams cost 28 per cent, more 

 than the beef. At the same time 4 per cent, more lobsters were 



* In these cases beef was used because fresh clams were not available at the time. 

 t On July 22 a large number of fourth stage lobster were removed from the bags and the 

 amount of food was accordingly reduced.
