LAND-LOCKED SALMON. 



A case of 20,000 eggs of this species was* shipped to the station 

 from Grand Lake Stream, Maine, arriving March 12 in most excellent 

 condition. The loss while in the hatching boxes was very trifling, 

 being less, in fact, than the subsequent loss of fish in the nursery tanks. 

 The fry were disposed of. as follows: May 28, delivered to Messrs. 

 E. K. Simonds and A. M. Eandolph 10,000, of which 8,000 were 

 planted in Union Lake, Oakland County, and the remainder in Cooley 

 Lake, same county; June 13, delivered 7,000 to same parties, who 

 planted them all in Union Lake; June 14, delivered the remaining 

 fry, about 1,800, to the Michigan Fish Commission. Total results, 

 18,800 fry.

 Oakland, and many other counties of the Lower Peninsula. It is about

 locked salmon was made in Union Lake last year, and this with the
