not economically worth a tenth part as much as the entire carcass.
During the present year, large quantities of Indian corn have been used
as domestic fuel, and even for burning lime, in Iowa and other Western
States. Corn at from fifteen to eighteen cents per bushel is found
cheaper than wood at from five to seven dollars per cord, or coal at six
or seven dollars per ton.-Rep. Agric. Dept., Nov. and Dec., 1872, p.

One of the greatest benefits to be expected from the improvement
civilization is, that increased facilities of communication will render
it possible to transport to places of consumption much valuable material
that is now wasted because the price at the nearest market will not pay
freight. The cattle slaughtered in South America for their hides would
feed millions of the starving population of the Old World, if their
flesh could be economically preserved and transported across the ocean.
This, indeed, is already done, but on a scale which, though absolutely
considerable, is relatively insignificant. South America sends to Europe
a certain quantity of nutriment in the form of meat extracts, Liebig's
and others; and preserved flesh from Australia is beginning to figure in
the English market. We are beginning to learn a better economy in
dealing with the inorganic world. The utilization--or, as the Germans
more happily call it, the Verwerthung, the BEWORTHING--of waste from
metallurgical, chemical, and manufacturing establishments, is among the
most important results of the application of science to industrial
purposes. The incidental products from the laboratories of manufacturing
chemists often become more valuable than those for the preparation of
which they were erected. The slags front silver refineries, and even
from smelting houses of the coarser metals, have not unfrequently
yielded to a second operator a better return than the first had derived
from dealing with the natural ore; and the saving of lead carried off in
