Very little difference was noted between morning and evening 
roadside counts from the end of July through October, although one 
route indicated that morning was more favorable. Our data probably 
are too meager to determine if any significant difference exists. 
A statistical analysis of calling counts covering the period 
from May 15-June 26, 1951 indicates that with 3 routes, 12 trips 
per route must be made in order to reflect a 15 percent change. 
| Calling counts should begin in this area (central Maryland and 
northeastern Virginia) no later than May 15, and the counts must be 
completed by the end of the third week in June to conform to the 
present schedule of formulating hunting regulations.
