        (I) The ability of the bird to thrive at least in 
    *QA se@tcions outside of the strictly grain farming 
 
    districts. 
        (2) The possibility of stocking extended areas by 
    establishing "spread centers" in favorable looalities. 
    (The *ioonsin plantings have been made in large numbers 
    n a restricted looality, while most of the plantings in 
    the Middle .est have been made as plantings of a fw

    more data on the efficacy of various methods of releasing

    a. Burning of roadsides lessens their use for early

    d. In the all small grain stubble provides cover, and 
 
later a supply of weeds above the snow forms cover and food. 
    e. Ears missed when husking stand inf corn are readily 
found and used by the birds during winter, preventing star- 
 
vation during periods of crusted snow. 
    f. Unhusked sweet corn patahes, or unhusked standing or 
 
shocked oorn, attract birds during late fall and winter.
