Extent of Damage in Field Sowing: 



Area Ho. 1 of the field sowing was devoted tc- de- 

 termining how seriously mice and chipmunks damage seed ---pots* 

 One-fourth of the spots were caged with wire screens, pre- 

 venting rodent digging, and the others left uncaged. Hilf 

 of the area had the seed covered 1/2", and the remainder had 

 I-1/2 11 of earth over the sown seed. 



Gemination was very poor and for this reason no 

 conclusive results were obtained. On the area, comprising 

 1/6 acre, 15 white-footed mice and 6 chipmunks were trapped. 

 Prom the looks of the seed spots it was judged that 9^/j of 

 the damage done was caused by white-footed mice and 2/ by 

 chipmunks. In the 1/2 M sowing, <)6$ of the spots had "been dug 

 into at the end of 11 days, while 76$" of the 1-1/2" sowing Imd 

 been similarlTf damaged in the same time. These figures ap- 

 ply, of course, to the uncaged spots; there was no damage 

 in the caged ones, since the screens pror ed very efficient 

 protection. The germination results are not very sug^ stive, 

 owing to the general poorness of germination. Even in the 

 protected spots and the shallow sowing it was very poor. 

 The number of seedlings per caged and per uncaged spot dif- 

 fered little. Of the caged spots, 60^ had no germination
