260 Thirty-fourth Annual Meeting. 
sent to my office for examination owing to my absence from Har- 
risburg. The tadpoles at the Wayne Hatchery, several hundred 
thousand in number, showed no signs of disease and are now 
being shipped to applicants. 
The experimental work in frog culture at the Corry Hatchery 
was exceedingly interesting. Mr. Wilham Buller constructed a 
little pond which he concluded the frogs would naturally take 
to. ‘Two hundred large frogs were brought from Lake Erie and 
placed therein. Within twenty-four hours they had all climbed 
the fence which surrounded the pond and departed to a nearby 
woods where they have since increased and multiplied marvel- 
ously. Last year he remodeled the pond, changing the form of 
the fence in such a manner that the frogs could not escape. 
More than 200 large frogs were placed within the inclosure and 
all lived through the winter and spawned this spring. ‘They 
yielded about 10,000 tadpoles and at the time of writing this 
paper they are still within the inclosure and apparently per- 
fectly healthy and contented. As it is well known that frogs 
will eat nothing but live food the real problem was to supply a 
large number in a small space and this was done by placing 
boards both on the wet grass outside the water limit and by 
anchoring others on the surface of the pond. On these boards 
were smeared molasses and honey. Bees and other insects were 
attracted in large quantities and the frogs fattened. The same 
method of feeding is now pursued. Both old and young frogs 
and tadpoles refuse maggots. 
The pond proper is about 20 feet long with a deep bottom of 
soft muck. During the winter months at the breast of the pond 
the water was about four feet deep and kept so until winter 
passed entirely away, when the supply of water was reduced to 
about a foot at the breast and only a few inches at the upper end. 
The bed of the pond sloped upward from the breast until only 
there was about a few inches from the foot of the mucky bed to 
the surface of the ground and this was occasionally flooded with 
water and the grass allowed to grow, grass being not only hiding 
places for the frogs, but also serving to attract insects. The 
fence was placed about four feet from the edge of the pond. 
Fitting close to the ground was placed a 12-inch board on edge 
on all four sides of the pond and a 30-inch mosquito bar was
