HOLLAND CARP PUT INTO HUDSON RIVER AROUT 1S30. 



By BAR1VET PHILLIPS. 



(Letter to Prof. S. F. Baird.) 



To-day Mr. James Benkard, vice-president of our fish cultural asso- 

 ciation, told me that his grandfather, Capt. Henry Eobinson, had, about 

 1830, first brought carp from Holland and put them in his ponds at 

 Newburg, and that he had therefore reason to suppose that the carp in 

 the Hudson were derived from these. In Frank Forester's " Fish and 

 Fishing," of 1849, page 166, you may find a statement to this effect, 

 which Mr. Benkard says is substantially correct. 



I have thought these data might be useful when the whole history of 

 the carp in American waters is to be written up.
