the ships of the inhuman slave importers, made the colonies reluctant to engage in the traffic. Nevertheless, the colonies experimented with this form of labor, Massachusetts beginning in 1638 and South Carolina thirty-three years later, and the conclusion was reached before the close of the eighteenth century that the slavery system of labor could be made useful in some latitudes, but could not be made profitable in all sections of America. Therefore, Massachusetts, following a Canadian precedent, abolished slavery after being a slave holding State over a hundred years, and soon after the American Revolution several States in the higher latitudes, all included in the old North Section of the original Plymouth colony, adopted the same policy.
But it will be observed that generally this Northern abolition was to take effect after lapse of time, and thus notice was given to the owners sufficient to enable them, if so disposed, to sell their property to purchasers living farther South who still found such labor remunerative. Some availed themselves of this privilege and converted their slaves into other more productive property. Some were conscientious or were attached to their negroes and, therefore, cheerfully gave them freedom. Others were philanthropic enough to keep the old and infirm, who on reaching liberation would be cared for by the State, only selling the young and the strong for a good price. Through these sales and the continuance of the slave trade, both foreign and domestic, the people in the Southern States were induced to invest their money largely in negroes, thus greatly increasing the population of that class within the boundaries of those States.
In all these changes of the labor system—this abolishing of slavery in several States—the moral side of the question does not appear to have had the uppermost consideration. The moral question certainly did have influence in Massachusetts and to some extent in other States; but the main reason for this early emancipation
