     The region here under dise.usston its the best remaining prairie ciken

     The Scottish grouse moors--about two or three times as large as the
here disacussed--yield a kill of nearly 2,00,000 head of grouse annually,
$5,000,000 in gross income. These are all wild birds, produced without artificial

propagation. There is no known reason My a similar yield from the Wisconsin

moors   should be impossible. In 1931, however, the entire state of 1iscom

variety to the hicken shooting-which has a very important bearing on the
value of shooting privileges.

which some outstanding attraction to snortsmen is available.

the discovery of a cheap method of treating the soil of food patches so they
grow white clover, might greatly a-ent the partridge crop, and thus add to

     The wetter marshes of central Wisconsin were, before drainage, highly

productive as a waterfowl breeding ground. 
     Some of the drained marshes are usable for ýWriculture, and are
more productive for prairie chickens by reason of their drained condition.
