to fill up in their wake. Mexico has but an infinitesimal immigration, and presents no great inducements to it at present. It must depend upon the local carrying trade and natural development of the industries and commerce of the country. It has a population per square mile but little less than that of the United States. These are of a natural intelligence, and capable of the stimulus of ambition when opportunities are opened. They are to be encouraged to be no longer satisfied with a bare subsistence for themselves, but to produce from their fertile lands a surplus, for which a market is now opened. They are to trade upon it and become amassers of wealth.
No less than 10,000 miles of railways are spread over what were once the old Mexican provinces of California, Arizona, New Mexico, Colorado, Wyoming, Nevada,
Utah, and Texas. Railways have brought these out of the nothingness in which they recently lay so vast and desolate. What must they not inevitably do at last for Old Mexico itself, so fully peopled, and scattered with centres of trade and of the arts of civilized life?
