I never before knew the full value of trees. Under them I breakfast, dine, write, read and receive my company.

And Botany I rank with the most valuable sciences, whether we consider its subjects as furnishing the principal subsistence of life to man and beast, delicious varieties for our tables, refreshments from our orchards, the adornments of our flower-borders, shade and perfume of our groves, materials for our buildings, or medicaments for our bodies.

If ever this vast country is brought under a single government, it will be one of the most extensive corruption, indifferent and incapable of a wholesome care over so wide a spread of surface. This will not be borne, and you will have to choose between reform and revolution. If I know the spirit of this country, the one or the other is inevitable.

Some men look at Constitutions with sanctimonious reverence, and deem them, like the ark of the covenant, too sacred to be touched. They ascribe to the men of the preceding age a wisdom more than human, and suppose what they did to be beyond amendment. I knew that age well; I belonged to and labored with it.

Reason and free inquiry are the only effective agents against error. Give a loose to them, they will support the true religion by bringing every false one to their tribunal, to the test of their investigation. They are the natural enemies of error and error only.

Had not free inquiry been indulged at the era of the Reformation, the corruption of Christianity could not have been purged away.
