The immensity of the consumption of forest supplies can not be measured accurately; but some idea can be formed of its vastness, when it is known that the one hundred and eighty-seven thousand miles of railroads and one hundred and thirty-seven thousand miles of telegraph lines in this country consume each year the annual growth or a forest equal to _one hundred and fifty million acres_. And nothing short of a large area of well-managed forest will prove adequate to _future_ demands. What else can the nation expect when at present statistics show the annual consumption, or crop, exceeds in value seven hundred million dollars? This is more than the yield of all the gold-mines and silver-mines, coal, iron, copper, lead, and zinc combined; and if these are added to the value of all the steamboats, sailing vessels, canal-boats, flat-boats, and barges in American waters, the sum would be still less than the value of the forest crop by an amount sufficient to purchase at cost of construction all the canals, all the telegraph and telephone lines in the United States. The value of the forest income exceeds the gross income of all the railroads and transportation lines, and is an interest ranking in importance far above all others in the United States. If this country ever becomes a Dalmatia--changed from a healthful, fruitful and salubrious habitation to a sterile, sickly waste, with decayed cities and crumbling greatness, history will not say “the Romans did it.” Man should ever remember prevention is better than cure. The worst of evils is prevented by the removal of the cause. And when the apathy and improvidence which now threaten the destiny of a rich and prosperous nation are removed, then, and not till then, can it truly be said that the lost Paradise of the Eastern Continent has been regained in the New World of the West. The people should understand, also, the inspired influences of living forests--trees--those musical mutes, upon those who breathe their sweet ennobling influence. The finest agricultural climate, perhaps, in the world, fell to the lot of Ohio. But this state will soon be obliged to do something to offset the destruction that is still going on with the little groves. When it came into the Union, it presented the grandest unbroken forest of forty-one thousand square miles that was ever beheld on this continent. A forest interspersed with hills and valleys, springs, brooks, and rivers; with a soil most inviting to the aspirations of agriculture. The natural conditions of things were such that the possessors of this inheritance soon desired occupation of the soil, and looked upon its trees with less favor than they did upon those who disputed their titles with the tomahawk. Indians could be induced to move out of the way, but trees were all disposed to stand their ground and take the consequences. Both were considered too numerous for easy advancement of civilization, and in the contest both got the worst of it.
