Hunting was conducted on the study area during 1 956 through 1959 
1961, 1963, 1966, 1968, and 1969 . A life tab le was set up for the 
combined years that followed those in which hunting occurred on the 
study area, beginning with i 960 , and another table was constructed for 
the years not following hunting-years. The mortality rate for the 
first year of recapture in the years that followed hunting-years was 
estimated to be 0 . 92 , while the mortality rate for the first year of 
recapture in the years that did not follow hunting-years was O. 67 . 
This illustrates an apparent contribution of hunting to annual mortality, 
supporting Bailey's observation in his Job Completion Report, 1965 , 
that total fal 1 -to-spring mortality was greater in years when there had 
been a harvest. 
The differing mortality rates suggest that nonhunting mortality 
during the winter is not entirely compensatory, that is, that factors 
producing mortality in winters of no hunting did not entirely overcome 
the differential and produce a mortality rate equal to that in years 
when there was hunting. Instead, the nonhunting mortality, although 
it may be partially compensatory, was also partly additive, yielding 
higher mortality rates when there was hunting than when there was not. 
However, although hunting increased the total mortality, the fall pop¬ 
ulations were not correlated with the preceding years' hunting. Thus, 
greater mortality resulting from hunting was apparently compensated for 
by either a greater production of young, or, more likely, by increased 
survival of young in the summers or falls that followed hunting.
