in diameter than those of similar age growing in the open. Like- 
wise, at relatively early ages — at 30 years for example — an acre that 
was half stocked might have trees of saw-timber size, whereas a fully 
stocked stand might not have any trees of merchantable saw-timber 
sizes.

Fig. 2. — Natural growth of longleaf pine for the past 4 seasons under fire protection ; 
nearly 8 feet tall in 9| years. Photographed 1 in June during period of rapid upward 
growth. (Jasper County,. S. C.) 
Table 1 shows, for different ages, the average height and diameter 
of longleaf pine trees growing in well-stocked, even-aged stands, on 
three different grades of land or situations. These figures, it is be- 
lieved, are approximately representative of the rate of growth in 
stands of good density over the range of longleaf pine. They are 
based upon the measurement of selected portions of 78 longleaf pine 
stands whose locations range from South Carolina to Texas.
