ing-boxes of the salmon-hatching establishment near Kexholin, in Fin- 

 laud, about 300,000 eggs, from which there were raised more than 200,000 

 young fish, which were placed in the Wuoksen River; and in the Kym- 

 mene establishment [also in Finland] there were often raised about 

 100,000 yonng salmon per annum. Professor Grimm has, therefore, seen 

 tit to establish a branch of the Nikolsk establishment in the building of 

 the Imperial Museum of Agriculture in St. Petersburg, whe^e the hatch- 

 ing of Corefjonus and salmon eggs is carried on upon a larger or at 

 least just as large a scale as in Nikolsk, but with more modern appara- 

 tus and at far less expense. 



As regards the other work of the Nikolsk establishment, and the re- 

 rults obtained by it, I take the liberty to refer my readers to two reports 

 published in a Prussian journal* by Professor Grimm, the one embrac- 

 ing the period 1869-1880, and the other the year 1881. One need not 

 be a specialist to learn from these reports that the Nikolsk establish- 

 ment, as a financial enterprise, or judged according to its usefulness 

 to the Government, is and always will remain a failure. Although, 

 judged from a technical point of view, the establishment is a model one, 

 and the judicious management of Professor Grimm leaves nothing to be 

 desired, its financial or economical results are either none at all or ut- 

 terly insignificant when compared with the size of the establishment 

 and the amount of money required even now for its support. The few 

 hundred trout and Goregonns which are at present carefully tended in 

 the Nikolsk ponds, and which, accordiug to Professor Grimm's report, 

 are the only visible result of the 25 years of the existence of this estab- 

 lishment, would, if brought into the market, even in St. Petersburg, not 

 realize the sum required to support the establishment for a siugle year. 

 Fishing in Lake Pestow, which belongs to the establishment, has not 

 increased, in spite of the most zealous attempts to raise fish iu that 

 lake. In 1872 more fish were caught in that lake than during any of 

 the succeeding years, even more than 1881, which was considered a 

 good fish year. Very few Corerjonus and still fewer trout are found in 

 the lake, although since Wrasky's time every year a large number of 

 young fish of both kinds have been placed in it. It appears from Pro- 

 fessor Grimm's report that in 1870 there were caught in Lake Pestow, 

 in all, 71 Coregonus and trout, and 1873 only 4 Coregonwt and no trout. 

 The transplanting offish, which is done here in the same manner as in 

 Finland, by transferring mature spawning fish from Lake Welje to Lake 

 Pestow, has been productive of better results. Thus the little marline 

 (Corcgonns albula), which was transferred to Lake Pestow in 1872, has 

 become entirely acclimatized, although even now it does not occur in 

 any very considerable number; and the smelt, of which a large number 

 of matured specimens were placed in Lake Pestow in 1872, have in- 

 creased to such an extent that annually 150 to 200 pud [5,100 to 7,200 

 pounds] of these fish are caught. The number of trout, however, seems
