scientific part of the v\'()ik is well arranged. There are a 

 biological laboratory (now, howexer. without a biologist) 

 and a chemical laboratory. The laboratory has issued num- 

 bers 1 to 9 of the periodical "Contributions from the Nikolsk 

 Laboratory," containing many good papers. At the labt)ra- 

 tory during the summer a number of young men are en- 

 gaged in the study of practical fish culture. 



There are in addition three auxiliary goxernment fish 

 hatcheries. One is in St. Petersburg in connection with the 

 Agricultural Museum, where rainbow trout and sturgeon 

 are hatched ; and another, with an annual capacity of 800,000 

 salmon eggs, is at the mouth of the Luga River not far 

 from St. Petersburg. A peculiarit}' of tliis latter hatchery 

 is that fecundated eggs are ke])t out of water. On a layer 

 of eggs in Coste's hatching 1)()x is placed a ])ed of cotton, 

 which is sprinkled witli waler three times a week. Of 

 course, when the fry are nearly read}' to hatch, a current of 

 water must l)e supplied. This method of incubation was 

 recommended by Dr. Oscar \'on (irimm and fixe years' ex- 

 perience on a large scale has demonstrated that the eggs de- 

 veloi) well, the loss ])eing less than in the ordinar}' manner. 

 The third branch station is in I)or])at. The Corcf/oiuis haevi 

 (resembling the whitefish of the L^niled States) is hatched 

 here, the capacity 1)eing one million. The Weiss hatching 

 jar is used. 



The abo\-e coxers all that the grn-ernment is doing in fish 

 culture. 1'he hatching of salmon on the Curo Ri\er was 

 attempted, but without success, and the fish-cultural sta- 

 tion established there is now closed. I 'experiments with 

 sturgeon ( Acij^enser nifheiiiis) . from a practical standpniut, 

 were a failure. 



There is no station for carp culture, although for a long 

 time the establishment of one has been under consideration. 

 The go\'ernment has made no appropriation for this work, 

 but it is hoped that in time there will 1)e a station for dis- 

 triliuting carp fry — -a matter of great im])ortance to certain 

 districts. In Poland and I^^^stland there are a large number
