Measure the Height of a Tree

TREE FELLING OR LUMBERMAN'S METHOD         Hold a stick upright in your outstretched hand. More backward away from the flagpole (or tree) you want to measure. Sight to the flagpole in such a way that the tip of the stick covers the top of the pole. The place where your thumb is, is its foot. Then swing the tick 90 degrees to a horizontal position. Notice the point where the tip of the stick hits the ground. Pace the distance from this point to the foot of the flagpole to get its height.
SHADOW METHOD Height of the tree = Length of the Staff x Length of Shadow of the Tree Length of the Shadow of Staff
REFLECTION METHOD         Place a washbasin with muddy water on the ground between you and the tree, at a point, which you estimate to be approximately as far away from the tree as the tree is high.  step back from the basin a distance equal to that from your eyes to the ground. You should now see the top of the tree reflected in the water. If not, move basin (keeping yourself at the same distance from the washbasin) until you see the treetop reflected. The distance from the basin to the foot of the tree is the tree height.
B.P.'s METHOD Height of the tree (AX) = CX x DB BC
PENCIL METHOD         Place a buddy whose height you know against the tree, or make a mark of your own height on the trunk. Step back, hold a stick or pencil up before you in your outstretched hand. With one ye closed, measure off on the stick with your thumbnail the height of your buddy. Then move the stick up to see how many times this measurement goes into the height of the tree. Multiply the height of your buddy with the number found. This gives you the height of the tree.
	INCH-TO-FOOT METHOD         Note the length of the staff from the ground to the point where sighting line cuts the staff in inches. The height of the tree will be same in feet.
