2 GO BULLETIN OF THE UNITED STATES FISH COMMISSION. 



It is owing to Mr. Rumpff that the oysters were conveyed from the 

 month of the Saint Lawrence River to the Little Belt in excellent con- 

 dition and in the comparatively short time of twenty days. I desire 

 nothing more earnestly than that his disinterested efforts may be crowned 

 with complete success, and that the Canadian oysters may thrive in the 

 waters of the Baltic. 



71.— NOTE ON THE CULTURE OF AMERICAN SAEIVION IN FRANCE.* 

 By C. RAVERET-WATTEL. 



On his return from a scientific mission to Tunis, Prof. Valery-Mayet 

 said : " Several American salmon have during the last year been caught 

 in the river Herault and the river Aude, although I had not placed any 

 in the last-mentioned river. This year some more have been caught in 

 the river Aude, but I have not been informed of similar catches in the 

 river Herault. The Aude is really more favorable for the development 

 of salmon than the Herault. Like the river Garonne, which is so rich 

 in salmon, it rises in the Pyrenees, and for three-fourths of its course 

 has an oceanic climate, like the Garonne." 



The secretary called attention to the transmission of eggs of the 

 Salmo quinnat, the young fry of which were placed in the Herault, where, 

 however, none of them were found again, while some have been caught 

 in the Aude. He thinks that it would be interesting to renew this at- 

 tempt to introduce salmon in watercourses, limiting these attempts, 

 however, to the ordinary kind (Salmo salar). 



If the Society should share this opinion, would it not be necessary to 

 decide at the present time what should be done when the time arrives 

 to make this experiment ? In his opinion it would be best to place the 

 young fry not near the mouths of these rivers, as has been the practice 

 hitherto, but rather near their sources, with tne view to come nearer to 

 the conditions of natural reproduction. 



The eggs might be sent at the opportune moment for subjecting them 

 to the process of incubation, by having an arrangement with Valery- 

 Mayet, professor at the Agricultural School of Montpellier, whose zeal- 

 ous and intelligent aid is entirely devoted to the Acclimatization Society. 

 Prof. Valery-Mayet should be written to now, asking him to state on 

 what conditions he could receive an instalment of eggs with the view 

 to their incubation and the placing of the young fry in the river Aude. 



Mr, Grisard, in this connection, recalled the fact that bull-frogs which 

 had escaped from the Acclimatization Garden had successfully propa- 

 gated their species in the marshes of the Bois de Boulogne, where at 

 this day they may be found.
