Buller. — Work of Pennsylvania Department 113 



almost countless numbers from the various waters in 

 the vicinity, and the Department will be able to furnish 

 all the frogs that may be needed by applicants in the 

 State. It is a rather curious fact that while these tad- 

 poles may be gathered and shipped by the million this 

 seems to have no effect upon the number of frogs remain- 

 ing, which appears to be about the same every year. 



At Torresdale is situated the shad hatching plant of 

 the Department, and the past year it did wonderfully 

 good work in the matter of hatching and planting shad, 

 although the season was not a propitious one. The water 

 failed to warm to the proper temperature, so that many 

 of the fish hatched too early, but they were planted right 

 off the hatching house and the Department hopes that 

 there was no loss. In this shad work the Department 

 had the co-operation of New Jersey and also, in a way, 

 of New York to which latter State the Department was 

 glad to turn over several million shad. That the work 

 of the Department in the hatching and planting of shad 

 has kept up the stock in the Delaware river is shown by 

 the number of good hauls of shad taken as far up the 

 river as Hancock and Cadosia in New York State. 



At Torresdale the hatchery is also used to supplement 

 the other hatcheries in hatching out in its batteries wall- 

 eyed pike, white fish and yellow perch. This hatchery 

 will also be used to furnish blue gills, sunfish and catfish, 

 to the breeding of which the waters are thoroughly 

 suited. 



At Erie is situated the hatchery to propagate the lake 

 fishes that go to make up the fishing industries of Erie, 

 the largest fresh water fish port in the United States. 



The spawn of these fish from the lake would be wasted 

 were it not for the efforts of the fish culturist. About 

 two years ago there was an epidemic of typhoid fever 

 in Erie and the State Department of Health ordered the 

 water treated, which proved deadly to the fish, and the 

 work of hatching these fish has since been conducted at 

 the Erie Auxiliary Hatchery, situated at Union City, 

 about 18 miles from Erie.
