protectorate which was contemplated, were such as the necessities of
the future should demand, and the good of others as much as our own
require, and this step by step, faster or slower, will, I believe,
finally embrace the continent of America and its adjacent islands.

I am not among those who desire to incorporate into our Union,
countries densely populated with a different race. Deserts, 'tis the
province of our people to subdue. A mere handful of inhabitants, such

Jerseys. The limit to these experiments will be where experience shows
deterioration. There is one cross which it is to be hoped you will
avoid: 'tis that which your Puritan fathers would not adopt or even
entertain. They kept pure the Caucasian blood which flowed in their
veins, and therein is the cause of your present high civilization,
your progress, your dignity and your strength. We are one, let us
remain unmixed. In our neighbors of Southern and Central America we
have a sufficient warning; and may it never be our ill-fortune to
