4. The supply of corn can be renewed, while in an ordinary 
shock the corn available is soon eaten. 
5. Power tepees shocks are needed. A field of 160 ordinary 
corn shocks was deserted on January 1 because the corn on the outside 
of the shocks was all eaten. Pour tepee shocks fed a flock of the same 
size and more corn was eaten in March than in January or February, as 
there was snow in March from the first to the twenty-first. 
6. Tepee shocks can be placed in cornfields, clover, fields, 
grain fields, or fields of ragweed in which prairie chickens are feeding.

7. Even if the stalks are short, the tepee shock can be made 
six or seven feet high. 
The hopper with backwheat was used for feeding sharp-tailed 
grouse. Buckwheat patcheswero deserted in November except where 
hoppers were set up. One pound of grain per bird was eaten per month. 
Cob corn can be fed on the ground near the hopper or under the lean-to. 
In 1928-29 buckwheat was stacked at the food patches and the straw 
scattered once or twice a week. In January and Pebruary the sharp-tails 
deserted the stations, probably due to the irregular supply of foods In 
1930-31 the hoppers were visited every day, and the number of birds did 
not decrease and at three stations the number increased during January 
and Debruar7. Sharp-tails learn to eat buaked cob corn and at least one 
flock which ate cob corn in 1930-31 was feeding on standingcorn in the 
fall of 1931. Bundles of buckwheat spread out around hoppers are fed on 
by sharp-tails and the best combination is probably a buckwheat food
