leguminous plants such as the clovers, peas, vetches and sain- 

 foin add nitrogen to the soil when they are used as cover crops. 

 In such instances these should not be used for cover crops, but 

 winter rye, rape or buckwheat may be used. Attention should 

 be called to our experience in having trees girdled by mice early 

 in the fall where rape was used in a newly-planted orchard. 



(8) Crimson clover has been tried at this Station many times. 

 The results show that in this location it is not reliable for a 

 cover crop. It is often winter-killed, and on hard clay land, 

 where it is most needed, it does not do well.,
