ground. It is not possible to distinguish one from the other by 
the leaves, as in such comparison there is no difference. 
“Yellow Cottonwood grows very round at the bottom, and 
holds to size much better than White Cottonwood. It generally 
has a thick bark; what we term as a corrugated bark. 
“White Cottonwood has a much thinner and softer bark, 
and is very apt to have a heavy spur root at the bottom. We 
mean by that it is liable to grow up somewhat flat-sided and 
ridged near the bottom of the trees. This is somewhat similar 
to the growth of oak. 
“Yellow Cottonwood will saw up very smooth, is soft and ten- 
der, and must be handled very carefully after being manufactured 
into lumber in order to prevent the splitting of the boards or 
their ends. It will dress out through a planer with a very 
smooth surface, and will break off square. It will also take a 
very nice polish after being surfaced. 
“White Cottonwood is tough and stringy, is very hard on 
saws in manufacturing, and will sometimes bend almost double 
before it will break, and after breaking the ends will be rough. 
“A White Cottonwood board put through a planer will not 
dress out smooth the entire surface, but there will be more or 
less spots that are fuzzy and rough, which is a serious objec- 
tion to the consumer, as it will not take an even polish. A 
White Cottonwood board exposed to the sun will also warp 
and twist to a much greater extent than a Yellow Cottonwood 
board. 
“Yellow Cottonwood lumber is not strictly yellow, consider- 
ing it from a color standpoint, nor is it strictly white. There 
is a tinge in the lumber which impresses you as different from 
a White Cottonwood board, which to the eye is very distinct.”

This variety of the Cottonwood is very desirable on account 
of the bright yellow leaves on the new growth in summer. 
It grows freely, and in Minnesota has proved as healthy as the 
species. It is valuable for occasional use to give variety to wind- 
breaks, and is said to be more largely planted in Europe for 
park decoration than any other American tree.
