apples. Under tliese conditions they bear as soon as apple trees. 

 Grafted black walnut trees need to be transplanted intelligently and 

 with care. There is not sufficient space in this bulletin to give de- 

 tailed planting instructions. They are to be found' however in Bulletin 

 No. 5 of the Association, which mav be obtained from the Secretarv 

 for 50 cents each, postpaid. 



If walnuts lie in the hull until the hull becomes soft, wet, and 

 black, the juice penetrates the sli.ell and darkens the kernel. If 

 luilled and dried as soon as ripe, the kernels are of a light waxy color, 

 much more attractive to buyers and of much better flavor. 



The fine varieties of black w^alnuts noted above crack out well with 

 the hammer. Inventors, however, have been working on tlie problem 

 of doing this by machinery, and already there are one or more devices 

 that are an improvement on the hammer, and it is to be expected that 

 tlie next few years will show substantial improvement in cracking ma- 

 chinery. 



Black walnut wood is one of the highest-priced woods grown in 

 the United States. Even the stumjDS are being dug up to be made 

 into veneers. An acre of old mature black walnut trees has a present 

 sale value as great or greater than the present value of farm laud in 

 many parts of the United States. Since we are cutting timber in this 

 country about four times as fast as it is being grown, it seems in- 

 evitable that its price must rise, and many authorities are nbw recom- 

 mending the planting of black walnut for timber alone. 



Black walnuts, like apples and other fruits, will not come true 

 from seed. That is to say, if black walnuts which crack out well, are 

 thin shelled, and fine flavored are planted, the trees that grow will 

 almost surely bear nuts which are deficient in these qualities and hardly 

 worth raising. Therefore, in order to get superior walnuts it is neces- 

 sary to set budded or grafted trees. 



Names of nurserymen specializing in budded and grafted walnut 

 trees will be sent to anyone writing to the Secretary of the Northern 

 Nut Growers' Association, Mr. Henry D. Spencer, Decatur, 111., and 

 enclosing a stamp for reply.
