If my present theme were the institution of slavery in general, I should endeavour to show that it has been a mighty instrument not for evil only, but for good in the providential order of the world. Almighty God, in His mysterious ways, has poured down blessings even through servitude itself, by awakening the spirit of sacrifice on the one hand, and the spirit of charity on the other.
