XXIV. —REPORT ON THE PROPAGATION OF SCHOODIC SALMON 
IN 1880-’81. 
By CHARLES G. ATKINS. 
1.—GENERAL SUMMARY. 
The only important changes or improvements in the fixtures at this 
establishment this season were the construction of two short aqueducts 
at the old house in the woods and the beginning of a new house at a 
cove on the west side of the lake close by the dam. The latter was at 
first intended to be used as supplementary to the other two houses, but 
it has proved so useful and to possess such facilities that it may yet 
become our headquarters. 
This has been, on the ee the most prosperous season we have 
experienced. We caught 2,171 Schoodic salmon of uncommonly large 
size; 1,473 were females Gn unusually large proportion), and 1,427 of 
these yielded 2,326,740 eggs, an average of 1,630 each, twice aN yield 
common ten years ago. There has been an increase in the vigor and 
hardiness of the embryos as developed in the hatching houses, due, 
possibly, in part, to the greater health and vigor of their parents, but 
probably in greater degree to the better treatment, the greater supply 
of water, and its better aeration secured by our new facilities. Result- 
ing from this was a greater degree of success in the transportation of 
the eggs shipped and in their subsequent hatching and rearing, and a 
marked improvement in the vigor of the fry hatched from the reserved 
eggs. The new house in which the latter were hatched stands on a 
hillside, and affords abundant facilities for aerating the water, which 
we so much needed at the old house. I expect this increased vigor of 
the young to tell on the future supply of adults in the lake. 
The losses sustained during the development of the eggs were only 
such as ordinarily oceur here. As determined by count or careful 
measurement, they amounted to 218,240, or 9 per cent., reducing the 
entire stock to 2,108,500. The 25 per cent. reserve still further reduced 
the number available for shipment to 1,581,500. A pro rata division 
gave the subscribers the following shares, viz: The United States, 
527,000; Maine, 124,000; New Hampshire, 124,000; Massachusetts, 
310,000; Connecticut,496,500. Allof these were shipped except 10,000
