FOREST PLANTING IN THE EASTERN UNITED STATES. 25 
SILVER MAPLE (Acer saccharinum Linn.). 
Silver maple is a rapid-growing tree, probably ranking next to 
cottonwood in this respect among the species discussed. It is also 
very hardy and comparatively free from serious insect or fungous 
attack. The tree, which reaches maturity in from 35 to 40 years, 
forms a rather crooked, twisted bole, and so yields very little lumber. 
Its chief value is for cordwood, or to insure a windbreak in a short 
time. Silver maple is occasionally used for posts for temporary 
fences, but is not durable in contact with the soil, and unless treated 
with a preservative, will not last more than two or three years. 
Since silver maple is easily and cheaply propagated, it is a good 
tree to plant for the production of cordwood in the Middie Western 
States, and probably also in any part of the Northeast, provided the 
plantation is made on well-drained soils which are not subject to 
excessive drying out. A spacing of 6 by 8 feet is close enough. 
In Table 4 $2.50 per cord has been assumed as the average stump- 
age value for the species.

EUROPEAN LARCH (Larix europaea deC.). 
European larch has been planted quite extensively in [lhmois and 
lowa, and to some extent in Rhode Island, Connecticut, and Massa- 
chusetts. Results, however, do not bear out the claims made for it 
(see Table 5). This is in part because plantations in this country 
have not been made in situations similar to the native habitat of the 
species which is in the higher, cooler altitudes; the trees have not 
always been properly spaced, and the cost of planting stock has 
often been excessive (in one case $51 per thousand and in several 
1The complete record kept of the amount of cordwood cut each year accounts for the large value of 
the products for this plantation.
