half a century, under existing circumstances, whereas 
by that time the demand will be quadrupled. Mr. 
Simmonds calculates the importation of wood into 
France during 1865 at 154,000,000 francs, or about 
£6,000,000, the ratio of import being at an increase, 
notwithstanding that the forest area of that empire 
was reduced, within a century, to one half—namely, 
from one third, in the latter part of the last century— 
to hardly more than one sixth now. But if the popu- 
lation of Middle Europe consumed proportionately as. 
much native wood as the inhabitants of the United 
States, then, in less than half a century, no forest 
whatever would be left in Europe. These conclu- 
sions are borne out by the U. S. Commissioner of 
Lands, the Hon. Jos. 8. Wilson. In the States east 
of the Mississippi, six billion cubic feet of wood were 
consumed for timber and fuel in 1860, at a time when 
no war laid hand on the forests. Hence, one million 
of acres of forest-land must be cleared, in the Eastern 
States of the Union, to find the wood for a years’ local 
requirements. Theshipment of lumber, in one of the 
latter years, from Chicago, was one billion four hun- 
dred million cubic feet, besides two hundred and sev- 
teen million laths, and nine hundred and twenty-eight 
million shingles. In 1866, the products of the Cali- 
fornia lumber trade were one hundred and ninety 
million of cubic feet, and thirty-eight million shingles ; 
in 1867, about two hundred million cubic feet. Que- 
bee exports about one million of cubic feet since a long 
period, annually, irrespective of home consumption. 
In the Pacific States exists only a supply adequate to 
the prospective wants of their people. The States 
west of the Mississippi import already timber that
