194 Thirty-Third Annual Meeting 
long enough to give you anything but the conjectures of the year 
and a half during which I have been noticing these special fac- 
tors. 
I am convinced of one thing, that there is less quarreling, 
less inquisitiveness, and fewer criticisms passed between our 
salmo iridius and our salmo fontinalis than you find occurring 
when you get five or six or ten families in an apartment house. 
The western charr, as you all know, comes from streams that 
flow through magnificent ravines oftentimes in sturdier waters. 
The fish as they came to me from the hatchery, as near as I 
could glean from the specimens shown here yesterday, were what 
might be called baby fingerlings. ‘They varied a great deal in 
size. They still had certain characteristics as they grew older, 
of the rainbow trout in its native heath. 
I at first fed the trout. I have always been opposed to feed- 
ing trout or fish of any kind on any artificial food if it were 
possible to approximate the foods that nature supplies. So I 
can say that up to date I have not been obliged to feed any of the 
fish that I have been raising on any of the ordinary so-called 
foods comprising liver, ete., ete. I have found that the natural 
supplies of foods I could always obtain. In the neighborhood of 
my pond there was a tremendous quantity of good old fashioned 
elusive tidbits called the angleworm or the earthworm, that the 
fish preferred to anything else. While the fish were quite small 
I secured worms, chopped them into small pieces, and fed the 
fish regularly with them. As they grew older I no longer chopped 
the worms up but threw them in whole. Of course they were 
devoured very eagerly, and in an amusing manner, because the 
little fellows would often each get the end of a worm in their 
mouths and have a sort of tug of war until they pulled the thing 
apart, or yanked it one from the other. The fish grew well. I 
tried one or two foods for experiment—not that my fish needed 
them—hbecause, as I say, I had a good supply of worms there— 
but I tried a food that seemed to me to be a cheap one, good and 
nutritious. I tried it simply to see if the fish would take it, and 
it went far beyond my expectation—I refer to well cooked vermi- 
eelli. J cooked it with a meat bone and salted it well, then 
chopped it in small pieces (not too small) and threw it out over 
the waters and the result was marvelous. The vermicelli being
