be destroyed by introducing small fish that feed at or near the 
surface of the water and freely eat the larve of the parasite 
swimming there.” He recommends to us the fresh water killy, 
sometimes called the grayback. 
I believe that something of the kind of pest mentioned has 
also gotten into the waters of other states. Michigan, Pennsyl- 
vania and Wisconsin have been reported as suffering from para- 
sitic diseases, and we would like to join hands with them in 
making a fight against the invasion of our troutwaters, especially 
our lakes. Our new Commissioner, Hon. James 8S. Whipple, is 
not only a thoroughly practical business man, but he also is an 
ardent fisherman and is particularly interested in hatchery prob- 
lems. He has invited scientific men to use our hatcheries for 
the purpose of study and experiment, and already we have stu- 
dents of the aquatic insects of the Adirondacks at work in one 
of the hatcheries. We hope for results and are willing to help 
secure them. 
But enough has been said, I think, to warrant a free and 
helpful discussion of the problem which |} believe confronts 
brook trout raisers. The cutting away of our forests may be 
at the root of all the trouble, and in our state we hope to restore 
the trees to our waste hillsides in time. But to do this will take 
at least the lifetime of this generation. In the meantime we 
can plant a species of trout that will thrive in the warmer waters, 
wherever there is a sufficient volume of flow to warrant it. The 
pollution we can in a great measure prevent, and it is an encour- 
aging thing to know that in the Adirondacks one of the largest 
paper mills has been trying to find a scientific method of getting 
rid of its waste and seems to have succeeded. 
I quote from the report of the legislative committee of New 
York appointed in 1904 to investigate this question. 
“While at Ausable Forks, the Committee visited the large 
pulp mills of the J. & J. Rogers Company for the purpose of 
examining their method of preventing the refuse from their 
mills from polluting the waters of the Ausable River. The 
subject of the pollution of Adirondack streams by pulp mills 
refuse has long been one of public interest, and the Rogers 
Company claims to have solved the problem to a considerable 
extent. The company for some time has had in its employ Mr.
