October 30 the sowing of the 2oth was examined. On a 

 strip through the center of the tiact lOOJi of spots where 

 seed was covered 1/2" deep appeared to have been disturbed, 

 while 91/ of these undoubtedly had been burrowed into, 

 since seed husks were found on them. In spots similarly 

 placed but with seed covered l ft deep, J2/ appeared to have 

 been molested and 38/4 &ad surely been dug into, as shown 

 by the husks of eaten seeds on the spots. As with the pre- 

 vious count, this damage was done during two nights after 

 sowing. As before, in this time four mice were caught in 

 five traps, and the bait of the fifth trap had been nibbled. 

 The traps this time were set as near as possible to the cen- 

 ter of the sowing area, and about in the center of the area 

 poisoned. 



It is evident, therefore, that poisoning a small 

 area in the early summer cannot be depended upon to rid the 

 tract of rodents to such an extent that- seed can safely be 

 sown on the place in the following fall.
