Cage tests indicated t-iat this was sufficient protectiov 



to the seed. To give further tests, a nursery bed frame 



was made mouse proof, spots representing seed spots we:;.;.. 



sown over the ground surface enclosed, a couple of mice 



were turned into the area, and the results following were 



obtained: 



Results of P & S No. ?: 



There were seed spots in the experimental 

 bed. These differed from one another in the seed being 

 encased in cartridges of screen wire, or not so encased; 

 in different sizes and forms of the cartridges; in dif- 

 erent depths of covering; and in different number of seed 

 per spot, as well as firming the covering soil or leaving 

 it loose. 



Encasing seed in screen cartridges is not effi- 

 cient protection, llany of the cylinders were dug up, 

 others were exposed by the mouse digging around them, 

 while seed was extracted in two instances by the mouse 

 gnawing the top of the cylinder and reaching the seed in 

 this way without digging up the cartridge. It does not 

 seem that the cartridges could be used even if they gave 

 better protection, for the stems and roots of the .cod-- 

 lings do not extend vertically, and consequently ait more 

 apt to pierce the sides of the grlinder passing through
