TUBE FOR AERATING WATER. 

President: One of our overseers has developed an appliance 
for his own use which I think is very valuable and we shall be 
very glad to hear Mr. Price explain his device, which consists of 
a tube for aerating water. 
Mr. John L. Price, Drayton Plains, Mich.: This is what we 
have named an aerating tube for aerating water in carrying fry 
and advanced fry in cans. (Demonstrating apparatus.) 
It is provided with four quarter circle holes operated by a 
valve at the top. An extra bottom is put on to keep the fry from 
being sucked into the inside of the tube and injured in that way. 
Now by raising the valve and slowly settling the tube in the can, 
it is filled. In lowering the tube exercise care to avoid touching 
the bottom of the can with the bottom of the tube. On the in- 
side there is a guage so that when the can is filled within an inch 
of the top the guage shows you one inch of water between the 
bottom of the tube and the bottom of the can, so that there is no 
danger of injuring the fish. 
When the tube is filled you raise your finger, raise the valve 
and that lets the water out. The extra bottom is fitted with a 
valve, and when you raise the valve above it closes that and forces 
the water to a circle, acts as a reducer and gives it force. This is 
provided with a screen and prevents the fish fry getting in there. 
The tube will fill in ten seconds, and empty in five, without in- 
juring any kind of fry. 
The tube holds just a gallon and three-quarters of water, and 
five applications of the tube practically empties a ten gallon can 
and it takes the water from the bottom of the can and aerates it 
on the surface. For carrying wall-eyed pike, shad and white-fish, 
we put another bottom on provided with'a finer screen, and that 
prevents the sucking in of the fry, and you get the same results. 
You can use it for a pail for a fresh supply of water, and it 
also takes the place of a siphon.
