Neosho Station, Missouri (William F. Page, Superintendent). 



Bainbow trout. — The fish retained from the product of the spring of 

 1890 for brood stock began to spawn in December, 1891, though but 

 20 months old. The first eggs were taken December 15, and the last 

 February 23. louring this period 112,185 eggs were obtained from 207 

 fish, an average of 542 eggs to each . The number of males used was 288. 

 Great difficulty was experienced in securing proper impregnation of

On January 16, 1892, Frof. Charles E. Kiley, of Drnry College, 

 Springfield, Mo., arrived at the station, and made a microscopic exam- 

 ination of the eggs and milt, in various stages, to discover, if possible, 

 the cause of the hard, glassy eggs so frequently occurring in this trout, 

 and a cure for the disease. His stay at the station was limited, but at 

 his request a series of eggs were prepared in a hardening mixture, and 

 sent him for further examination. In eggs which had had no contact 

 with milt, as also in the fiuid which so frecpiently accompanies the 

 extrusion of these hard, plump eggs, he discovered a tapeworm like 

 parasite. It is hoped that from the results of Prof. Riley's investiga-
