Page 35 - It grows on soils with all the different degrees of moisture content from wet swamps to dry sandy uplands. It prefers, however, the intermediate flat, moist lands, edges of swamps, and well-drained bottoms...
Page 36 - Over large areas longleaf pine occurs in nearly pure stands, though a scattering of single loblolly trees is nearly always present. As. the soil moisture increases loblolly becomes more plentiful, until it is the dominant species. As on loblolly pine land, there is nearly always a lower story of hardwoods. Where the soil is very dry oak sprouts sometimes get possession of small areas to the exclusion of pine. Diameter breasthigh. Clear length.
Page 57 - ... inches. Loblolly pine, being a tree of very rapid growth and being well suited to the locality, should be favored as much as possible, that its range may be extended. This tree should, so far as possible, replace the cypress and hardwoods, since cypress is too slow growing to be profitable, and the hardwoods are not now and will not be for a long time of much commercial value.
Page 31 - Many standing trees are killed each }Tear by fires. Owing to the thick bark of both loblolly and longleaf pine, these trees resist tire to a remarkable degree, and a tree not previously injured seldom succumbs to a grass fire. Slash fires, however, are sometimes so intense that they kill trees outright, particularly small ones. Hardwoods are not easily killed by grass fires after they reach a diameter of 6 or 8 inches, though they are mucti more susceptible than pines.
Page 28 - Stand of ash, maple, and hickory orer the whole tract. COMPARISON OF TWO-THIRDS AND DOYLE RULES. Table IX shows the total yield for each holding from the three most important species — loblolly pine, longleaf pine, and cypress — scaled both by the two-thirds and by the Doyle log rules. In each case the scale by the two-thirds rule is far in excess of that by the Doyle rule. Species. Yield. Log rule. Species. Yield. Log rule.
Page 40 - Shortleaf pine is of too rare occurrence to be a factor in the commercial forest. With the exception of spruce pine, it is the pine least represented on the tract. It occurs for the most part as scat tered individuals over restricted areas, occasionally forming 12 to 20 per cent of the stands. It is found in mixture with either longleaf or loblolly pine, but more f requently with the latter.

It is most important here that the representation of loblolly pine be increased. It is estimated that, for the present, one man should be able to do all of the marking at a yearly cost of $375. NECESSITY FOE A FOEE8TER.
Page 37 - A small patch of ground is free from fire for a few years, and a group of trees springs up on it. If fire be kept out after cutting, the stand will come up as even-aged forest, provided sufficient seed trees be left. Loblolly pine is not encroaching upon the longleaf land to any marked extent. Very few cases of loblolly following longleaf were seen.
Page 47 - The number of years that must elapse before a cut equal to the present may be again obtained is also shown. This table is constructed from an average of all acres of timber measured on the tract. Future yields are obtained by ascertaining how many trees of each diameter are left on the ground if a given diameter is cut to (see Tables I, II, and...
