Wind River Tests with Gaged Mice and Chipmunks: 



Tests similar to the Wenatohee ones were a few 

 months later carried on at the V7ind River Nursery. 



Zinc chloride, which was next to the best sub- 

 stance -cried on the Wenatchee Forest, failed absolutely. 

 Two tests were made with different mice, and in each case 

 all the treated seed were eaten. 



lodofonn, the third best substance on the Wenat- 

 chee, was not used in the sanig form as previously, but in 

 the way it was us ed it failed. Instead of putting the 

 iodoform on the seeds, it was placed on the surface of the 

 earth :ir which seed was buried. One-fourth teaspoonful 

 was cpvi.uTOLed over soil in a box 5" x 6" in size, but seed 

 buried '1-1/4" under it were smell ed and dug up. 



Hap thai ene, fifth best on the Wenatchee, wae

 used ae in the case of iodofonr placed or: the surface of 



soil in which seed was buried, instead of on the seed as 

 formerly. In the form used last it failed. 



ITux vomica, iodoform, starch, and flour, made 

 into a pellet 3/8 tf to 1/2" in diameter, inclosing 10 seed, 

 was only fairly efficient. Of b pellets, two fed to each 

 of three mice, 3 were nibbled, .1 broken to pieces, and 

 the seed eaten, and 2 were left untouched. 



The only conclusion which can be rnaae is that
