in this manner they rolled and tumbled and swayed rapidly 
toward the dead fish on which they fastened themselves at once. 
The tadpoles even at the extreme end of the pond some twenty 
feet away seemed to be cognizant of the presence of the food, and 
large numbers of them made their way in the same strange 
evolutions to the tidbit and settled themselves so thickly thereon 
that within five minutes it was impossible to see anything but a 
mass of tadpoles outlined lke a fish. They stripped every par- 
ticle of flesh from the dead bass within an hour. 
Returning to the tadpoles hatched in 1904, by the first of 
August there was not one in the Erie ponds, but had changed 
entirely into a perfect frog. Shipping began in July. Three 
hundred and fifty were sent on each application and they were 
sent in tadpole form with the cans about half filled with water. 
The first shipment of tadpoles having legs were made in the 
same manner, namely in water, but it was found that they did 
not carry well, and the frogs, it was learned, carried best when 
placed in damp glass. It was unnecessary to send any messen- 
ger along with either the tadpoles or frogs, excepting where more 
than one railroad transfer had to be made. Nothing could be 
done as far as known, to benefit them by sending messengers, and 
no aeration is necessary because the higher the temperature the 
better the tadpoles would probably like it. * 
This year two ponds at the Erie hatchery were set aside for 
hatching wild spawn and about 60,000 were hatched in each 
pond. Owing to weather conditions the water was much colder 
than last year and the hatching period was from 15 to 18 days. 
The tadpoles were much smaller than those hatched last year, 
probably on account of the cold water. They appeared, how- 
ever, to be as healthy and active. They remained in this condi- 
tion for about five weeks, when suddenly the tadpoles in one of 
the ponds sickened and died. Thirty thousand died in one night. 
The rest were hurriedly planted in the marshes at Erie the fol- 
lowing day, some dying on the way. The tadpoles in the other 
ponds remained apparently all right for about ten days, when 
they too died, the whole pond becoming empty of live tadpoles 
within thirty-six hours. An examination showed that on the 
stomachs of each tadpole was a round red spot. Unfortunately 
no microscopic examination was made and no specimens were
