planted in the field are sure to be destroyed by mice or squirrels. 

 The best plan is to gather the nuts in the fall, keep them over winter 

 between layers of sand, and plant them in the spring- where the trees 

 are to stand permanently. If the nuts are properly handled and not 

 disturbed, from 50 to 75 per cent of them will germinate, but, since 

 rodents are always to be feared, it is well to plant two or three nuts 

 in each hole. They should be planted about 2 inches deep. The 

 growth of the seedlings during the first season should be from 6 to 

 9 inches. 



The spacing will depend upon the object of the plantation; if nuts 

 are the object chiefly desired, wide spacing (about 20 feet by 20 feet) 

 is essential, whereas for a woodlot about 6 feet by 6 feet is right. 



Shagbark hickory does well when planted in pure stands, but if 

 the plantation is to be allowed to grow to a considerable age, some 

 other slow-growing species may be mixed with it, or, after it has 

 attained a good growth, it may be planted with a species tolerant of 

 shade. Hemlock and sugar maple are good trees for this purpose. 



CARE AFTER PLANTING. 



If the plantation is on tillable land, it should be carefully culti- 

 vated until the trees become large enough to shade the ground. In 

 any case live stock of all kinds should be excluded and protection 

 against fire should be provided for. If the plantation is attacked 

 by the hickory bark beetle, the infested trees should be cut and the 

 bark should be burned before the middle of May, or advice should 

 be asked of the Bureau of Entomology, U. S. Department of 

 Agriculture.
