etc., when first set out in a small garden, should be protected by 

 paper, or tin collars, or a barrier of some sort, which should extend 

 into the ground an inch or so, and two or three inches above the 

 surface. This can be removed when the plant becomes tough 

 enough not to invite attacks from the cutworms. On large acreages

 since thev normally live in sod.

 seed as a result of the work of white grubs upon the roots. Pota- 

 toes following sod were severely injured, five or six grubs being 

 sometimes found in one hill, and, in places, clover suff'ered severely. 

 The period of the most damage in 1912 was between the last of June 

 and the latter part of September. In the last named month, a
