Steam skidders aid greatly in reproduction, since they tear up the 
soil and thus make an excellent seed bed for the pines. They also 
materially lessen the danger from fire by mixing the very inflammable 
material on the ground with soil, so that it does not burn readily. | 
HEIGHTS OF STUMPS. 
At present loblolly pine stumps are cut about 2 feet high, and long- 
leaf pine often higher. In the case of longleaf pine it is often advisable 
to cut high stumps to avoid an old box or an injury which has caused 
a pitchy butt. In the case of loblolly pine, the only thing that should’ 
cause a high stump to be cut is a bad fire scar or other unsoundness. 
Table XXVIII shows the amount of timber saved by cutting stumps 
1 and 14 feet high instead of 2 feet, as is done at present. It is seen 
that for trees of the larger diameters the saving is considerable. It is 
recommended that all pine stumps be cut not higher than 1% feet, 
unless the butt of the tree is unsound. With the present distribution 
of age classes, this would mean a saving of about 54 million board feet: 
over the whole tract. |

SUPERVISION AND PROTECTION. 
MARKING TREES FOR REMOVAL. 
It is necessary to mark all pine trees that are to be cut if the best 
results are to be obtained. Ordinarily this will simply mean the mark- 
ing of all pine trees 14 inches and over in diameter breasthigh, but in 
case this leaves too few trees for seed purposes, trees of larger size 
must beleft. When this necessity occurs, one or two trees capable of 
withstanding wind, and in other ways well suited for seed trees, must be | 
selected and left on each acre. When trees over the diameter limit | 
are left, enough trees below this limit should be removed to compen- | 
sate for the larger ones. In removing trees below the diameter limit. 
great care should be exercised. These trees should not be removed 
where the stand is open, but from areas where the number of small. 
trees is great. |
