Measuring Trees

Aready and rapid mode of measuring a tree wheu the approximate height is all that is required consists in using the Bngers of the hand and with a man to stand at tho tree. See illustration originally given by Country Gentleman. ïwo men are walking along the margin of woods or over a field ■with tered trees. One of them, who measnres 6 feet high -with bis hut on, stands at tbe foot of the tree. The other takea his positiou several rods distant, and holds out his opon hand at arni's length, so that his fonr fiugcrs shall cover the man at the tree. Theo he moves his hand upward ou tbe face of the tree to the top of tho nian's bat, thcs giving 12 feet high. Theu auother move, and ho has 18 feet, theu 24, arid so on, tiü the wholo tree is measured to the top. A little practico will enable hiin to inake such measurements rapidly and vith considerable accuracy, not more than a single miuuteor two being required for any tree, or for the height of the clear trnnk up to the branches, when valuable timber is nnder examination. Auothcr mode istomeasure tho shadow. The mthority already quoted says: This raay be easily done, if tbe ground is leve! and the tree casta a clear shadow by snulight. Measure the shadow, and then holdiug a measared polo erect observe the proportiou of tbe shadow to the pole and calcúlate the height of the I tree accordingly by simple arithmetic. If the shadow is equal to the height, no calculation is uecessary; if the shadow is twice the pole, theu divide the shadow of the tree by two, and so on, for any other length.
