I now proceed to show by testimony, that at the date of the United States constitution, and for several years before and after that period, slavery was rapidly on the wane; that the American Revolution with the great events preceding accompanying, and following it, had wrought an immense and almost universal change in the public sentiment of the nation of the subject, powerfully impelling it toward the entire abolition of the system—­and that it was the general belief that measures for its abolition throughout the Union, would be commenced by the individual States generally before the lapse of many years.  A great mass of testimony establishing this position is at hand and might be presented, but narrow space, little time, the patience of readers, and the importance of speedy publication, counsel brevity.  Let the following proofs suffice.  First, a few dates as points of observation.

The first general Congress met in 1774.  The revolutionary war commenced in ’75.  Independence was declared in ’76.  The articles of confederacy were adopted by the thirteen states in ’78.  Independence acknowledged in ’83.  The convention for forming the U.S. constitution was held in ’87, the state conventions for considering it in ’87, and ’88.  The first Congress under the constitution in ’89.

Dr. Rush, of Pennsylvania, one of the signers of the Declaration of Independence, in a letter to the celebrated Granville Sharpe, May 1, 1773, says:  “A spirit of humanity and religion begins to awaken in several of the colonies in favor of the poor negroes.  The clergy begin to bear a public testimony against this violation of the laws of nature and christianity.  Great events have been brought about by small beginnings. Anthony Benezet stood alone a few years ago in opposing negro slavery in Philadelphia, and NOW THREE-FOURTHS OF THE PROVINCE AS WELL AS OF THE CITY CRY OUT AGAINST IT.”—­(Stuart’s Life of Sharpe, p. 21.)

In the preamble to the act prohibiting the importation of slaves into Rhode Island, June 1774, is the following:  “Whereas, the inhabitants of America are generally engaged in the preservation of their own rights and liberties, among which that of personal freedom must be considered the greatest, and as those who are desirous of enjoying all the advantages of liberty themselves, should be willing to extend personal liberty to others, therefore,” &c.

October 20, 1774, the Continental Congress passed the following:  “We, for ourselves and the inhabitants of the several colonies whom we represent, firmly agree and associate under the sacred ties of virtue, honor, and love of our country, as follows: 

“2d Article. We will neither import nor purchase any slaves imported after the first day of December next, after which time we will wholly discontinue the slave trade, and we will neither be concerned in it ourselves, nor will we hire our vessels, nor sell our commodities or manufactures to those who are concerned in it.”
