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



Rainhoiv trout. — The fish retained from the i)roduct 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. During 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 

 the eggs, and not more than 35 per cent of the eggs taken were fertil- 

 ized. The trouble was the same as is described by Mr. Frank N. Clark 

 in his report of the operations at the Northville Station during 1882. 

 (Report U.. S. F. C, 1882, p. 819.) 



On January 16, 1892, Prof. Charles E. Eiley, of Drury 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 fluid which so fre(iuently accompanies the 

 extrusion of these hard, pluinp eggs, he discovered a tapeworm-like 

 Ijarasite. It is hoped that from the results of Prof. Eiley's investiga-
