22* REPORT OF COMMISSIONER OF FISH AND FISHERIES. 



"When, therefore, requests are received from foreign governments tlie 

 stipulation made of paying tlie actual cost is cheerfully comi)lied with 

 by them, and a graceful act of international comity is thereby made x^rac- 

 ticable. 



It will not be forgotten by those who have read the reports of the 

 Commission from the beginning that before the home establishments for 

 procuring the eggs of salmon were in operation, the German Govern- 

 ment presented 250,000 eggs of the Khiue salmon to the United States, 

 and sent them over in charge of a special messenger. Those that sur- 

 vived were hatched out at the establishment of Dr. Slack, at Blooms- 

 bury, ]^. J., and introduced into the Delaware Eiver, where some of 

 them are believed to have returned as mature fish to their original start- 

 ing point. 



A portion of the correspondence with foreign governments on this 

 subject will be found in the Appendix under the respective heads of dis- 

 ti'ibution offish, and the amount of service rendered in reply to applications. 



The applications, for the most part, were for California salmon and 

 whitefish from the different provinces of New Zealand, from Australia, 

 Ecuador, Germany, France, and the Netherlands. All have been re- 

 sponded to excepting that from Ecuador, which has no waters suitable 

 for any of the fish included in the operations of the United States Com • 

 mission. 



Apart from direct applications for the fish, numerous requests are on 

 file for help in other ways. I have already referred to the co-operation 

 of the States of Connecticut, Massachusetts, California, Maryland, «&c., 

 in the way of joint work in the production of shad, salmon, and the like, 

 and have given the details to a sufScient extent. 



A noteworthy instance is shown in connection with the operations for 

 the proijagation of salmon at the Clackamas fishery on the Columbia, 

 where an association of canners combined to furnish the sum of $27,000 

 with which to start a hatching-station in order to maintain the supply. 

 At their urgent request I detailed Mr. Li\ingston Stone, superintendent 

 of the McCloud Eiver hatchery, to start this establishment by furnish- 

 ing i^lans of a hatching-house, dams, &c., and supervising their construc- 

 tion. This was done in the summer of 1877, and a thorough organization 

 was effected, from which it is hoped the yield of salmon on the Columbia 

 Eiver will be continued at its present average. A further account of the 

 enterprise will be found in a subsequent part of the report. 



The great success of the methods adopted by the United States Com- 

 mission for the hatching of fish and of securing the ready return of the 

 fish from the sea to their spawning-grounds, by means of artificial fish- 

 ways, has induced a large correspondence with foreign establishments, 

 especially with the Deutsche Fisherei-Verein of Germany, the great or- 

 ganization which has in charge the interests of all the German fisheries 

 and composed of some of the most eminent specialists in Germany, and 

 having its headquarters at Berlin. Application was received in the
