ive race must be the encouraging of European
immigration, such as Spaniards, Italians, and others. The Americans of
the United States cannot furnish Mexico with new citizens or workers,
tillers of the soil, or builders, or miners; for the United States has
her own territory to develop, and, moreover, the American citizen will
never perform manual labour outside his own country. Both the Americans
and the British will furnish capital and brains for Mexico's
development, but of workers in the field they will send none.

In this connection, however, the future may hold much, unsuspected at
present. The question is constantly to the fore now as to whether the
white man is able to perform manual work in the tropics, and large
portions of Mexico and Spanish-America generally are situated in
tropical zones. The reply to the question is twofold. First, the
advancing science of sanitation, and kindred matters, are showing that
the unfavourable conditions encountered in tropical lands are capable
of change, and that regions hitherto unhealthy can be made habitable
for alien white men. There can be little doubt that sweeping adverse
statements about the impossibility of the occupation by white races of
the tropical regions, especially of America, will be belied in coming
years. The other consideration bearing upon this question is that there
is no necessity for the white man to work in the tropics to the same
extent that he works in temperate climates. Nature has done half the
work herself, and it will surely be found that invading man must adapt
his habits to her laws there, rather than pretend to implant his own
methods arbitrarily. Thus, a minimum of work in the tropics secures
shelter and sustenance to man there. But, so far, this facility of
living has been an element for human deterioration rather than for
progress. The Indian squatters of the Mexican tropics, or the savage
bands of the Amazonian forests of South America, do not tend towards
development. But it may be different when an educated and civilised
race has, perforce, to take up its residence in such regions. The
struggle for life, for bread, roof, and clothing, is so much less
severe that it may transpire that man, in such regions, will have more
time to develop the intellectual side of his life, and a new stimulus
and purpose might be brought to being from such a combination of race
and environment. It is apparent already to the observer that the
Spanish-American
