•ground between tlie rapid leaping brook, the home of the 

 speckled trout (Salmo fontinalis) and that frequented by the 

 white and yellow perch. They furnish wholesome fish diet, 

 and recreation to those who before their introduction had 

 only the Cat, the Sucker, the Fall fisli and a few minnows. 



Although never taken in sufficiently large quantities to be 

 found in central markets, yet there are hundreds of families 

 residing in the region drained by the Upper Potomac, who 

 are saved thousands of pounds of meat annually by the in- 

 troduction of this wholesome change of diet. We, through 

 the kindness and aid of Hon. Arthur P. Gorman, President 

 of the Chesapeake & Ohio Canal, who rendered us every 

 facility, when the water was taken from the oanal in Decem- 

 ber, 1874, procured some five hundred black bass, many of 

 them large fish, with which we stocked many of the rivers. 

 We hoped to procure a much larger supply, but when wo 

 recollected that the abundance in the Potomac is the result 

 of the introduction of not more than one hundred in 1854, Ave 

 may expect excellent fishing in the streams stocked in four 

 or five years, if the fish are protected. It has been asserted 

 that they had destroyed all other fish, and were themselves 

 diminishing, we, however, found quantities of small fish in 

 seining the deep places in the canal, and but few bass. We 

 •attribute the diminution of the bass in some of the upper 

 waters to the fact that on the approach of cold weather, they 

 move down stream, seeking the deep holes in which they lay 

 dormant during the winter. Having passed over the dams 

 and Great Falls in their downward journey they find it im- 

 possible to return, so the upper regions are each year deprived 

 of many of their fish. There would be a more equal distri- 

 bution if these obstructions were provided with proper fish- 

 Avays. 



Trout — (Salmo fontinalis .) 



This fish, so much prized by the angler and epicure, in- 

 habits the clear mountain streams and rippling brooks, in 

 which there is to be found a limited supply of food. This 

 renders it impracticable to make them so plentiful, as to have 

 any influence on the food product of our waters. 



This consideration decided us not to devote any portion of 

 Ihe appropriation to stocking streams with this beautiful fish,
