ter are included^ representing the average for the State of Con-

 stracted from the logging expenses show the profit on the different 

 products. 



Throughout the region small portable or water mills saw the 

 timber. This is bought by the tract for a lump sum, rather than 

 for a stumpage price per unit of volume. Owing to the farmer's 

 ignorance of estimating, he loses by this arrangement. If the 

 volume tables enable land owners to estimate more accurately and 

 thus to obtain better sale values for their timber, the publication of 

 this bulletin would be well worth while, even should it accomplish 

 nothing else. 



"With the data at hand as to the quantity of various products 

 which can be secured from chestnut trees of different sizes and the 

 cost of manufacturing the same, it is a simple matter to draw con- 

 clusions as to relative profit from ties, lumber, poles, piles and 

 cordwood." This the author has done, showing the stumpage value 

 for trees of different diameters. Poles, lumber, ties, piles, and 

 cordwood, in the order named, are the most profitable products. The 

 stumpage values range from $0.05 for an 8-inch tree cut into ties 

 to $8.35 for a 30-inch tree cut into a pole. However, local condi- 

 tions and prices may often change the relative value of the products. 

 This is especially true of lumber and poles. Trees can in many 

 places be cut into lumber more profitably than into poles. 



Tables of growth in height and diameter are presented, as well 

 as some specific examples of the growth that may be expected 

 under forest management. The height growth is shown to be prac- 

 tically at a standstill for sprouts after the first 50 years, and for 

 seedlings at 60 to 70 years. After the first decade the diameter 

 growth of chestnut sprouts and seedlings is approximately the 

 same. This, however, does not correspond to studies of diameter 

 growth for chestnut in other sections of the country. 



Applying the figures of growth, the author constructs a table 

 showing among other things the percentage increase in volume and 

 in value of chestnut trees. These percentages remain high until 

 comparatively large sized trees are obtained. For example, a 

 24-inch tree is growing in volume at the rate of 3.1 per cent annu- 

 ally, and in value at the rate of 6.7 per cent annually. On the basis 

 of the values in this table, interesting conclusions regarding the
