His masterly faculties and his real goodness made him a prophet always. He saw the future, and strove to hasten its promises. The elevation and happiness of the human family were his daily thought. He knew how to build as well as to destroy. Through him disabilities upon trade and oppressive taxes were overturned; also a new treaty was negotiated with France, quickening commerce and intercourse. He was never so truly eminent as when bringing his practical sense and enlarged experience to commend the cause of Permanent Peace in the world by the establishment of a refined system of International Justice, and the disarming of the nations. To this great consummation all his later labors tended. I have before me a long letter, dated at _London, 7th November, 1849_, where he says much on this absorbing question, from which, by an easy transition, he passes to speak of the proposed annexation of Canada to the United States. As what he says on the latter topic concerns America, and is a prophetic voice, I have obtained permission to copy it for this collection. "Race, religion, language, traditions, are becoming bonds of union, and not the parchment title-deeds of sovereigns. These instincts maybe thwarted for the day, but they are too deeply rooted in nature and in usefulness not to prevail in the end. I look with less interest to these struggles of races to live apart for what they want to undo, than for what they will prevent being done in future. _They will warn rulers that henceforth the acquisition of fresh territory, by force of arms, will only bring embarrassments and civil war_, instead of that increased strength which, in ancient times, when people were passed, like flocks of sheep, from one king to another, always accompanied the incorporation of new territorial conquests. "This is the secret of the admitted doctrine, that we shall have no more wars of conquest or ambition. In this respect _you_ are differently situated, having vast tracts of unpeopled territory to tempt that cupidity which, in respect of landed property, always disposes individuals and nations, however rich in acres, to desire more. This brings me to the subject of Canada, to which you refer in your letters.
