Mode of measuring timber.
Section 263
SEC. 263. Mode of measuring timber. — Except as hereinbelow provided, all timber shall be measured and manifested in the round or squared, before being sawn or manufactured. The volume of all round timber shall be ascertained by multiplying the area of the small end by the length of the log, the diameter of the log to be measured exclusive of the bark; but if the end of a log is irregular the average diameter shall be used; and in order to ascertain the volume of a log more than eight meters long, the diameter of the middle of said log, or the average of the diameters, at both ends thereof, shall be used as basis. If a log in the round, cut under license, is measured and manifested by forest officers, the Director of Forestry shall make due allowance for rot, cavities, or other natural defects; but from any decision of the Director of Forestry in this respect, an appeal shall lie to his Department Head, whose decision shall be final. The manifest of timber cut by licensees operating sawmills in or near the forest shall be attested by forest officers whenever practicable. The volume of squared timber shall be ascertained by multiplying the average of the cross section measured by the length, to which thirty per centum shall be added for loss in squaring: Provided, however, That if squared timber cut under license is measured and manifested by forest officers, the Director of Forestry shall make due allowance for rot, cavities, or other natural defects; but from any decision of the Director of Forestry in this respect an appeal shall lie to his Department Head, whose decision shall be final. The privilege of manifesting timber after squaring shall, however, is granted only to licensees who have squared their logs in the forests with the tax and intend to take it to the market in this form. If sawn or otherwise manufactured timber is found which has not been manifested in accordance with the provisions hereof, the corresponding forest charges shall be assessed on twice the volume of the actual contents of such sawn or manufactured timber.
