while 71/j of the uncaged spots were without seedlings. The 

 most seedlings per spot were in an unprotected spot. Ger-

On P & S No. 3j at least 82$, and probably more, 

 of the seed spots had been dug into by mice or similar ani- 

 malSj when examination was made July 22, 1912, a month and 

 a half after sowing. 



On P & S No. 4, a count on the north slope showed 

 86$ dug into and one on the south slope showed fji?$ of the 



certainly dug into by rodents. The time of sowing and 

 of examination were similar to P & S No. 3* 



On P & S Ho. 5 1 w&ere the spots were made with a 

 tamp, and were 3" in diameter arrl l t! to 2" deep, a count on 

 the north slope showed at least 73$ du S into by rodents, and 

 one on the south slope showed 76$ molested. 

 Results of Poisoning 20-30 Acres in Spring, and Sowing Seed 

 in Fall: 



P. & S. Ho. 6 is an experiment in poisoning to rid 

 a small tract of rodents so that seed could safely be sown on 

 it. The trial failed. The area was poisoned with strych- 

 nine-treated wheat on June 15, 1912. The wheat was poisoned 

 by Dr.. Dea.rbcrn of the Biological Survey, and was distribut- 

 ed partly "by him and partly under his direct supervision. To
