Arizonia. The copper mining
countries are another illustration of the principle upon which success
is based, namely, that concentrated talent, effort and capital are
necessary to a development of the resources of a country.

When we look into the manufacture of this article, we shall find a new
element in the future growth of towns to arise in this region. At
present, a large portion of this copper is shipped abroad to be
smelted. But is there not every reason, as well of economy as of
material, for carrying on smelting, and all other manufacturing
processes, at the point of production? The cost of transporting the
raw material is greater than that of carrying the manufactured
product. But when all the elements of successful manufacturing exist
where the raw material is found, then the economy of the process is
doubled. Of metals, of navigation, of food, we have shown there is an
inexhaustible supply. But there is also coal near enough to supply the
last and only material which might be supposed wanting. Coal is found
in the Southern Peninsula of Michigan, in abundance and of good
quality. This coal is found at Jackson and at Lansing. This was a
matter of so much importance that Prof. Douglas, of the State
University, proceeded immediately to analyze it.

The following are the principal results of his analysis. It was made
chiefly in reference to the manufacture of gas:--

"The coal was of the bituminous variety, having a jet black color and
slaty structure. It was readily ignited, burning with a dull flame and
smoke, the fragments comminuting more or less by the heat. It had a
specific gravity of about 1.25.

"100 parts gave volatile matter 50.780, sulphur 4.028, iron 4.400,
ash 8.400, carbon (not volatilized) 41.600.

"The value of coal for the manufacture of gas is usually estimated by
the amount of volatile matter it yields at a full red-heat."

Of ten samples of English coal, this had more volatile matter than
six. Of American coals, it had more of the burning principle than any,
except one. The quality of this coal is unquestionably good, and its
distance from Mackinaw is no objection, since access can be obtained
both by water and railroad. Both the coal and iron used in the
manufactures of Cincinnati are brought from places distant from one
hundred to five hundred miles; and yet scarcely any place in America
has prospered more by manufactures than the Queen of the West.
Mackinaw has more than the advantag
