APPENDIX XI. 



SPECIMENS OF SALMONID^E FOR PROF. AGASSIZ. 



Cold Spring Trout Ponds, 

 Charlestown, N. H., January 24, 1871. 



To Fishermen and Sportsmen. 



C^^ENTLEMEN: Professor Agassiz is preparing an 

 ^ illustrated work of the American Salmonidae, includ- 

 ing all the trout and salmon, as well as whitefish, of this 

 country. To enable him to make this work complete, he 

 requires live specimens of every variety of trout, salmon, 

 and whitefish found on this continent. The American 

 Fish Culturists' Association are endeavoring to help him 

 in this great undertaking, and would beg you to send to 

 Professor Agassiz,* for his investigation, any specimens 

 of these varieties that may come within your reach, — 

 alive, if'possible ; if not, dead, — and especially to forward 

 to him any new or rare specimens that you may discover. 

 Samples of the winninish, land-locked salmon, and the 

 rarer kinds of the lake trout and sea trout, are particu- 

 larly requested. Further appeal for your co-operation 

 seems unnecessary, as you cannot but feel that no Amer- 

 ican can do too much for Professor Agassiz. All speci- 

 mens should be directed to Professor Agassiz, Museum 



* If the specimens cannot be kept alive, and are small, put 

 them just as they are into a bottle of alcohol and water, and 

 send them. If the specimens are large, treat them thoroughly 

 with a wash of carbolic acid, and express them at once to the 

 Museum, or skin them, without severing the head or tail, and 

 send the skin, head, and tail in the same way, or in alcohol.
