The States should make and enforce their own laws. 
No other power can do it so effectually and well. Their 
legislatures are familiar with the necessities of their 
States, are quick to respond to the wants of different 
localities, and by frequent contact with their constituen- 
cies know their wants. 
If a general awakening of the lake States can be had | 
as to the necessity of proper action to maintain their 
fisheries as above suggested, there is no reason why the 
great food supply furnished by these waters may not be 
maintained at least in their present value, with a hope of 
future increase. 

IMPREGNATING EGGS 
OF THE RAINBOW TROUT. 
By Wm. F. Pace, 
The object of this paper is to bring to the notice of 
this Society, and through it to the notice of fishculturists 
in general, a subject which has not received that degree 
of attention its importance would warrant; the wish is 
to arouse interest sufficient to lead to a correct and, if 
possible, a practical solution of the difficulty of impreg- 
nating the eggs of the rainbow trout. 
On page 819 of the report of the U. S. Commission 
of Fish and Fisheries for 1882, under the report of Mr. 
Frank N. Clark, is the earliest record of a peculiar inci- 
dent occurring in the work of impregnating the eggs of 
the rainbow trout. This peculiarity can not be better 
described than by quoting Mr. Clark’s report ; 
“Our facilities being first-class and having been uni- 
“formly successful in the propagation of trout, not ex- 
“cepting the preliminary experiments with rainbow trout 
“for four seasons, I had confidently expected to embry- 
“onize from one to two hundred thousand eggs from the 
“stock of z~zdeuws hatched and grown at this station; but 
“we succeeded in getting only 45,000 eggs (many of the
