In the earlier stages of our national existence the opinion prevailed with some that our system of confederated States could not operate successfully over an extended territory, and serious objections have at different times been made to the enlargement of our boundaries.  These objections were earnestly urged when we acquired Louisiana.  Experience has shown that they were not well founded.  The title of numerous Indian tribes to vast tracts of country has been extinguished; new States have been admitted into the Union; new Territories have been created and our jurisdiction and laws extended over them.  As our population has expanded, the Union has been cemented and strengthened.  As our boundaries have been enlarged and our agricultural population has been spread over a large surface, our federative system has acquired additional strength and security.  It may well be doubted whether it would not be in greater danger of overthrow if our present population were confined to the comparatively narrow limits of the original thirteen States than it is now that they are sparsely settled over a more expanded territory.  It is confidently believed that our system may be safely extended to the utmost bounds of our territorial limits, and that as it shall be extended the bonds of our Union, so far from being weakened, will become stronger.

None can fail to see the danger to our safety and future peace if Texas remains an independent state or becomes an ally or dependency of some foreign nation more powerful than herself.  Is there one among our citizens who would not prefer perpetual peace with Texas to occasional wars, which so often occur between bordering independent nations?  Is there one who would not prefer free intercourse with her to high duties on all our products and manufactures which enter her ports or cross her frontiers?  Is there one who would not prefer an unrestricted communication with her citizens to the frontier obstructions which must occur if she remains out of the Union?  Whatever is good or evil in the local institutions of Texas will remain her own whether annexed to the United States or not.  None of the present States will be responsible for them any more than they are for the local institutions of each other.  They have confederated together for certain specified objects.  Upon the same principle that they would refuse to form a perpetual union with Texas because of her local institutions our forefathers would have been prevented from forming our present Union.  Perceiving no valid objection to the measure and many reasons for its adoption vitally affecting the peace, the safety, and the prosperity of both countries, I shall on the broad principle which formed the basis and produced the adoption of our Constitution, and not in any narrow spirit of sectional policy, endeavor by all constitutional, honorable, and appropriate means to consummate the expressed will of the people and Government of the United States by the reannexation of Texas to our Union at the earliest practicable period.
