188 TRANSACTIONS OF THE [may 18, 
In 1889 the writer saw a few young male salmon at Karluk in 
company with schools of adult fish seeking to enter the river. 
This probably occurs annually, but the return of red salmon 
measuring only six inches in length in such numbers and with 
such regularity as noted by Mr. Barling is a circumstance of 
very great interest. There may be some doubt whether these 
young fish have really entered upon their sea life, but the ob- 
server states positively that they were ‘‘standing inshore with 
the adults,” and his testimony is entitled to credit. 
This species, the red or blue back salmon, is one in which the 
migratory habit is strongly developed; it ascends rivers to a 
distance above one thousand miles from the ocean, to spawn 
around the shores of deep, cold lakes and in their tributaries, 
preferring waters whose highest temperature rarely exceeds 55 
degrees Fahrenheit. We know something about the spawning 
habits of this salmon and others of the same genus, but its 
marine life is a sealed book, and even its going and coming are 
about as little known as its geological age. The necessity of 
systematic and continuous observations upon this highly impor- 
tant economic family of fishes is obvious. 
NEw YORK AQUARIUM, 
BATTERY PARK, NEW YORK, April 13, 1896. 
STATED MEETING. 
May 18th, 1896. 
The Academy met, with President STEVENSON in the chair. 
About twenty-five persons present. The minutes of the last 
meeting were read and approved. 
The Section of Geology and Mineralogy was at once organ- 
ized. 
The first paper of the evening was by Mr. Heinrich Ries, en- 
titled “ Notes ofa Trip Through the Marble Quarries of West- 
ern New England and Eastern New York.” Mr. Ries sketched 
out the geology and geographic distribution of the limestone quar- 
ries examined along the Hudson River and Lake Champlain on 
the northward trip, and the marble quarries in the Green Moun- 
tains and Berkshire Hills on his return south. His remarks
