Tue Fish-hatching establishment at West Barnstable was 
begun in the spring of 1868. The experiments have as yet 
been confined mostly to trout, of which we have hatched this 
year some 60000, as well as 2000 salmon ova w hich were 
procured in New Brunswick by the State Commissioners of 
Fisheries, by whom they were presented to us. As the pro- 
cess of hatching goes on during the transport of the eggs in 
wet moss, we lost several by pe hatching on the way iu 
the cars. 
The place selected for building the ponds to contain the 
parent trout, was a swampy piece of land at the head of a 
brook of considerable size, running into the salt water after 
a course of a mile and a half or two miles, and containing 
half dozen or more pure springs, the waters of which formed
