BULLETIN OF THE UNITED STATES FISH COMMISSION. 
Salinou have been seen spawning a short distance np the river from Denuysville 
and thence all along in suitable places to above Starters Rips. It is Mr. Lincoln’s 
opinion that the destruction of the forest by the Saxeby gale, on September 4, 1869, 
and subse(piently by tire, has been injurious to the welfare of the salmon, as the 
stream is now less protected from cold and in some places it freezes to the bottom, 
killing eggs and young. 
Alewives have again become abundant, but the “bluebacks,” which were deeper, 
proportionately shorter, and fatter tish, and once common, are no longer found. Ale- 
wives run upstream during May and June and after a few months the young, about 
2 inches long, are seen coming down in abundance. They continue to descend until 
late in the season, after the ice has formed. Some do not get down until spring, when 
they are about 5 or 6 inches long. This species spawns in the dead water. 
On the morning of October 7 Mr. Lincoln opened the gate in the tishway at his 
milldam in Denuysville. Thousands of young alewives were seen passing down tail 
hi st until they reached the turbulent water below, where they were tossed about until 
they found quiet water in the eddies and pools among the rocks. Several specimens 
were caught in our hands and were identihed as Clupea cestivaUs. 
At the time the old upper mill was in existence the proprietor, being told that 
pickerel were hue edible and gamy hsh, introduced some into his mill i)ond. They 
multiplied greatly, practically exterminating most of the other. species, leaving only 
“roach” and horupouts.* Mr. Lincoln thought that the pickerel were brought from 
Massachusetts. They are now held in ill repute. 
Cathance Lake is about 2 miles long and miles wide, situated about 8 miles 
northwest of Denuysville, on the boirndary line of Charlotte and Cooper townships. 
It is a deep, clear, cool body of water, containing an abundance of brook trout ranging 
in size up to as high as 4 xiouuds. Landlocked salmon are also common, having 
been introduced there some years ago. They do not attain a greater weight than 5 
pounds. 
The Cathance River takes its rise in this lake and joins Dennys River about 
miles above Denuysville. It is a rocky stream, smaller and more turbulent than 
Dennys River. Brook trout are abundant, especially at its upper course.
