In selling walnut on the stump the owner should accompany the 
buyer, who is usually an experienced walnut cruiser, and with liim 
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 4J feet above the ground and its 
length to the first living branch. The girth divided by 1 will give
