The Book of Woodcraft Cottonwood. (Populus deltoides) Small and rare in the northeast. Abundant and large in west; even 150 feet high. Wood as in other poplars but weighs 24 lbs. Leaves 3 to 5 inches long. These and most of the poplars have the leaf stalks flattened laterally so that the slightest puff of wind vibrates the leaf, this with its shiny surface clears it of dust and enables it to live in dry places where different leaves would be stifled.
