410 HISTORY OF THE FISHES OF MASSACHUSETTS. 
markets are usually supplied from the rivers, where they are taken in nets. At 
Medford nets are stretched across the river, having in their middle a large bag 
capable of containing from fifteen to twenty bushels; as the eels are going up or 
down the river they are caught, and are kept alive for the supply of the market 
in large ditches, excavated near the river, which are supplied by the tide-water. 
About three thousand pounds are yearly taken at Watertown. Those taken in 
summer, when they are able to procure the britt, and other fishes upon which they 
feed, are much the larger and richer, weighing from one to nine pounds. In Oc- 
tober, 1844, I saw an individual measuring two feet and ten inches in length, and 
weighing three pounds and a half, which was taken in Medford River, which agreed 
in its measurements with the one I have above described, and was, I suppose, a 
mere variety, although it was of a dark olive-brown above, and of a slate color 
beneath, without the slightest tint of yellow, and .a very slight tinge of red along 
the anal fin. The fishermen suppose this peculiarity of color, which it appears they 
occasionally see, is owing to their being confined entirely to fresh water, and never 
having visited the sea.
