yearlings on this diet was 6 per cent. of the number of fry. 
That the fish produced by this diet were normal and 
healthy is beyond all question, and if evidence is wanted 
it is to be found in that their progenitors, spawning them 
at two years old, were raised on the exact same diet. The 
natural question is, what does this food cost? Shorts cost 
at Neosho, Mo., 90 cents per 100lbs. One pound of shorts 
makes 3.6 lbs. of mush. Mush therefore costs one-quarter 
of acent per pound. Liver during 1892 was delivered in 
Neosho from Kansas City for 34 cents per pound. From 
this I deduce the cost of an average daily ration for 1,000 
yearlings was 1.707 cents. If this food isnot cheap enough 
to suit your views, [ then ask your attention to the fol- 
lowing condensed history of an experiment in feeding trout 
which I undertook last summer. On August 9, 12,000 
healthy trout fry which had up to that time received the 
same general treatment and allowance of food as we usu- 
ally give, were deprived of all animal or flesh food. From 
that time until they were shipped in February, 1893, not 
an ounce of animal food was given them, and it is certain 
that the natural animal food which they might have ob- 
tained was the very least. Their allowance throughout 
this time was 45 lbs. of mush per day, costing a fraction 
under one cent per 1,000 fish per day. At the end of the 
year they averaged 4 in. in length, and an average thousand 
fish weighed 27.5lbs. The fish were normaland healthy, 
and though under the average size for Neosho, they were 
above the average of at least two American establishments. 
In closing this branch of the subject, let me say that the 
food composed of a mixture of animal and vegetable mat- 
ters more nearly approximates than any other artificial 
trout food in use, a rational, healthy diet; and when we 
consider its capabilities of creating and sustaining the 
heaviest growth in the shortest time, we must admit that 
it is not an extravagant diet. A study of Mr. Nicklas’s 
article heretofore referred to conclusively shows that fishes
