266 ANNUAL EECORD OF SCIENCE AND INDUSTRY. 



tion to new localities. There is, however, one fish that is of 

 great value, and which can be introduced without as much 

 doubt of the propriety of the act as exists in regard to the 

 pike. We refer to the black bass {Grystes of authors). This 

 inhabits, in one variety or another, the basin of the great 

 lakes, of the Mississippi Valley, and the upper waters of the 

 streams of the South Atlantic coast as far north as the James 

 River. Within a few vears it has been transferred with sue- 



m 



cess to streams previously uninhabited by it to the Potomac, 

 for one, where it is now extremely abundant. During the 

 past summer some public-spirited gentlemen of Philadelphia 

 collected among themselves a fund to stock the Delaware 

 with this noble fish, and obtained about seven hundred, prin- 

 cipally in the vicinity of Harper's Ferry. These were carried 

 alive in large tanks to the Delaware, and deposited in that 

 stream at Easton, about two hundred of the number dying 

 by the way. The same party of gentlemen propose to use a 

 surplus fund in their hands in experimenting upon the re- 

 stocking of the river with shad and salmon. 



LIVING EYELESS PISH. 



Visitors to the Dublin Zoological Gardens have been much 

 interested in some living specimens of the eyeless fish found 

 in the Mammoth Cave, recently carried there, and now in 

 perfect health. The small specimens are so transparent that 

 the vertebral column, the heart, and optic bulbs may be dis- 

 tinctly seen. In the largest there are dark red spots over 

 the optic bulbs, which, it is suggested, are due to their having 

 been kept in an iron tank, which may have given color to a ru- 

 dimentary pigment of the membrane. 12 A, Oct. 6, 1870, 454. 



STOCKING WATERS OF NEW YORK WITH FISH. 



The Commissioners of Fisheries for the State of New York 

 have lately announced, in the public papers, their readiness to 

 furnish, free of expense, living black bass, catfish, white bass, 

 rock bass, roach, perch, sunfish, and pike-perch, for stocking 

 the waters in any part of the State of New York, provided 

 parties desiring them will send an agent to receive and take 

 charge of them. All of these are now bred at the state es- 

 tablishment at Caledonia, and applications for them are to be 

 made to Seth Green, Rochester.
