BULLETIN 033, U. S. DEPARTMENT OF AGRICULTURE. 



In selling walnut on the stump the owner should accompany the 

 buyer, who is usually an experienced walnut cruiser, and with him 

 estimate the length and small diameter of each log that will be cut, 

 keeping a detailed memorandum of the scale and the sizes agreed 

 upon. 



The average form and development of trees of different diameters 

 at breastheight are shown in Table 12, which may be used as 

 a rough volume table for average trees, particularly if they have 

 been grown in groves or wood lots. The trees used as a basis grew 

 in Ohio and Indiana, but the form is probably very much the same 

 throughout the range of walnut, except where conditions are very 

 unusual, as around the outer limits of the range, particularly toward 

 the west and southwest.

Short-cut methods of approximating the contents of standing 

 trees are often of use, as in the case of preliminary correspondence 

 between buyers and prospective sellers. According to a very satis- 

 factory method used by one firm in gaining a general impression of 

 the amount, the owner is requested to send in a list of all trees offered 

 for sale, giving the girth of each at 4-£ feet above the ground and its 

 length to the first living branch. The girth divided by 4 will give
