the junction of the cone with the furnace pipe several horizontal slits 
are made, each about three inches long. The furnace pipe just above each

slit is then bent in an inch or so. This hopper has the advantage of 
being mouse, rabbit, and deer proof. As its feeding spaces are small, the

grain is not as visible as it is in the hoppers built of lumber, and 
greater pains must be taken to train the birds to eat from it. As th1e 
feeding space is very limited it would be necessary to use several of these

hoppers where there are a large number of birds. If the cone on the inside

is placed six inches from the bottom the hopper may be fitted over a stump.

If small birds are to be fed a sloping platform may be built for them to

stand on. 
The Corn Shock System.--Corn shocks have always been recommended as 
the best method of winter feeding most game birds. They have several ad-

vantages. A game bird can live on corn alone for several months. Corn 
shocks are never entirely covered with snow. They are large enough to 
make it possible for game birds to find them easily. Corn shocks have 
several serious defects, but fortunately most of these defects can be 
remedied. Quail can burrow into a corn shock and perhaps feed on the 
corn which is on the inside of the shock, but most other game birds must

rely on the corn which is exposed on the outside. Mice and rats often eat

most of the corn which is on the inside of the shock. In cornfields where

prairie chickens feed the available corn on the outside may be exhausted

by the end of December. Figure ( ) shows a corn shock with the outside 
ears eaten. This corn shock represents the condition of a ten-acre field

of corn shocks in Wood county on January 1, 1931.  In many regions corn 
is not shocked but is put in the silo, and even if not put in the silo 
the shocks would contain no ripe corn. These defects can be remedied 
as follows:
