these ways. The easily gotten stores of the mines and forests are
exhausted; the soil over many millions of acres has been robbed of its
fertility. The nation is now engaged in reckoning up what is left in
the treasury of its natural resources, estimating how best to conserve
and make profitable use of what is left.

The nation might have done this sooner, but there was in the West
always fresh land to open up and in the East, after a time, a new
source of income in the factory industries, that were more and more
profitably absorbing capital and labor. So that although pioneer
conditions gradually passed away, and it became less easy to wrest a
living from plain or mountain or mine, the idea of finding out what
was wrong, improving methods of agriculture, conserving the forest
wealth by continual replanting or working the less rich mines at a
profit through new processes, or the utilization of by-products, did
not at first suggest itself.

When, on the other hand, we turn to the manufacturing occupations,
we find that they have followed an analogous, though not precisely
similar, course of evolution. Certainly from the first the
manufacturers showed themselves far ahead of their fellows in the
economical management of the raw material, in the adoption of every
kind of labor and time-saving device and in the disposal of refuse.
But in their way they have been just as short-sighted. They carried
with them into the new occupations the very same careless habits of
national extravagance. They, too, went ahead in a similar hustling
fashion. This time the resources that were used up so recklessly were
human resources, the strength and vitality of the mature man, the
flesh and blood of little children, their stores of energy and
youthful joy and hope. By overwork or accident, the father was cut
