Mechanism, working on land and sea, is opening up the resources
of the world. And now, another allied art, that of chemistry, more
especially biology, is in process of removing one of the remaining
obstacles to full development, by making active life possible, and
even pleasant, in the tropics. It is predicted by some enthusiasts
that, in the near future, it will be healthier and pleasanter to live
in the tropics, and even do hard work there, than in the temperate
zone. When this day comes, and it may be soon, the development of
the riches of lands within the tropics will begin in earnest, and
wealth undreamed of now be realized.

The opening of the undeveloped countries means a continuing increase
of wealth to the nations that take advantage of the opportunity,
and a corresponding backsliding to those nations that fail. It
means over all the ocean an increasing number of steamers. It means
the continuing increase of manufacturing in manufacturing countries,
and the increasing enjoyment in them of the good things of all the
world. It means in the undeveloped countries an increasing use
of the conveniences and luxuries of civilization and an increasing
possession of money or its equivalent. It means, throughout all
the world, an increase of what we call "Wealth."

In discussing a subject so great as sea trade, while it may be
considered presumptuous to look fifty years ahead, it can hardly
be denied that we ought at least to try to look that far ahead.
To look fifty years ahead, is, after all, not taking in a greater
interval of time than fifty years back; and it certainly seems
reasonable to conclude that, if a certain line of progress has
