10 TREES AND TREE-PLANTING. 
trees last year to supply the Chicago market with lum- 
ber. These figures are indeed appalling, and may well 
alarm any one as to the future source of our timber sup- 
ply. There is no hope of any diminution in the future, 
for Chicago will require more lumber this year than she 
did last. The demand is ever increasing, and the sup- 
ply ever diminishing. Between the two the end must 
come soon, and the grand old forests disappear. After 
the Saginaw, Muskegon, Menomonee, Manistee, and Lud- 
ington sources are exhausted, the Rocky Mountain slopes 
and Washington Territory will be stripped of their for- 
ests, and then we will have all that is worth taking. 
Every year we denude 8,000,000 acres of trees, and plant 
less than 1,000,000 acres to replace them. The end is so 
plain, even a fool may read it as he runs.
