NINTH ANNUAL MEETING. 9 
trout and California salmon looks much more like the salmon 
than it does like the trout, being quite silvery on the sides and 
long and slim in shape, as you will see by this specimen which I 
have had preserved. There are some sixty of these now living, 
from eight to twelve inches long, and they are so shy that they 
can hardly be examined, and dart hither and thither when any one 
approaches the pond in which they are kept, in the utmost terror 
and uneasiness. The young of the salmon-trout and brook- 
trout have the square tail of the brook-trout, that of the salmon- 
trout being quite forked, and although they have no carmine 
specs, have smaller spots than the salmon-trout, and are quite 
stocky in shape. These bid fair to be a fine fish; those at the 
New York hatching-house being six or,eight inches long on 
January, 1880. 
The cross of the shad and herring was made in order to save 
the eggs of ripe shad when no ripe males were to be had. 
Although the male was an inferior fish, the cross was not expect- 
ed to be an improvement over the mother, still such as it was, it 
was so much clear gain. There is in consequence a fish, although 
not the best kind of fish, where otherwise there would have been 
none. The young have thriven well, and we hear of their being 
caught on the rocky shallows of the Hudson river. They prob- 
ably are not migratory, and can be taken with rod and line. It 
would seem from all accounts that they are quite numerous, and 
I give a letter from Mr. Van Wyck, about them at the close of 
this article. The cross of the shad and striped-bass has never 
been heard from, so far as we can affirm positively. As some of 
these were hatched in the autumn of 1876, and quite a large 
number in the succeeding year, we hoped that some of them 
would have been taken full grown before this time. A reward 
was offered in 1879 for any specimens, but none were presented. 
The final outcome of this experiment is left entirely in the dark. 
Such care and pains were, however, taken when the impregna- 
tion was effected, to make sure that no germs of shad-milt were 
in the water that was used, or could by any possibility come in 
contact with the spawn, that there can be no doubt of the fact of 
_ the cross. Whether so odd a fish had the power of sustaining 
itself, obtaining its food, and holding its own in the struggle for
