lutnbia, and 1,000,000 to Fred Mather, Cold Spring Harbor, New York, 

 which were hatched out and deposited in waters of Long Island. Re- 

 ports received indicate that the eggs reached their destination in splen- 

 did condition^in every instance. 



Lake Trout. 



After an intermission of one year the collection of the eggs of this spe- 

 cies was resumed the present season, the total number collected being 

 1,300,000 eggs. The lirst eggs were taken on October 15, and the season 

 closed about November 20. During the winter 402,000 eggs were for- 

 warded to State fish commissions, 45,000 to the National Fish Cul- 

 ture Association, London, England, and 40,000 to Central Station, Wash- 

 ington, District of Columbia. Of the balance 50,000 fry were hatched 

 out and retained at the station. On December 16, 1887, 560 2-year- 

 old lake trout were planted in Long Lake, Alpena County, Michigan. 



Brook Trout. 



Very gratifying success has attended the work with this species the 

 present year, the total production of eggs being 274,600, of which 

 175,000 were forwarded to State commissions and 40,000 to Central 

 Station, Washington, District of Columbia. Of the remainder 45,000 

 fry were hatched out and retained at the station for future distribution. 

 All of the shipments reached their destination in very good condition. 



Rainbow Trout. 



The best results received from this species in the history of the sta- 

 tion, both in the number of eggs and the percentage of good eggs 

 taken, have been obtained the present season. The total number of 

 eggs taken was about 325,000, of which 225,000 were good. It is the 

 intention to hold and rear as many as possible of this fish until they 

 are able to take care of themselves, when they will be distributed to 

 suitable waters Very few of the eggs, therefore, were shipped the 

 present year, only one lot of 10,000 having been forwarded to the Cas- 

 talia Club, of Castalia, Ohio. The first eggs were taken on December 8, 

 and the season closed May 4. The total production of fry was 157,000, 

 which were retained at the station. During the season 8,578 one-year- 

 old fish were distributed to open streams, lakes, and applicants for ponds 

 in Michigan, Missouri, Ohio, Indiana, Arkansas, Tennessee, and Kan- 

 sas, the greater part of the distribution having been done by Fish 

 Commission car No. 1. 



Brown Trout. 



Of this species 26,763 eggs were taken from fish raised from the orig- 

 inal stock of eggs received in the spring of 1883 from Germany. Five 

 thousand of these were forwarded to the Michigan commission, and 

 18,000 retained at the station. The success with this fish in the fry 

 state has not been very satisfactory, the mortality being considerable 

 during the first 3 months. After this time, however, they feed well 

 and grow rapidly, the loss being almost imperceptible. On December 

 20, 1887, 500 one-year-old trout were forwarded by car No. 1 to the Michi-
