But it is impossible to close these pages without mentioning the extraordinary merit of this latest, and, in all likelihood, this last production of Clarkson's pen. It is indeed a most able performance, and has been admired by some of the ablest controversial writers of the age, as a model of excellence in controversial writing. Plain, vigorous, convincing, perfectly calm and temperate, devoid of all acrimony, barely saying enough to repel unjust aggression without one word of retaliation, never losing sight for a moment of its purely defensive object, and accordingly, from the singleness of purpose with which that object is pursued, attaining it with the most triumphant success,--no wonder that the public judgment has been loudly and universally pronounced in its favour, that its adversaries have been reduced to absolute silence, that its author's name has been exalted even higher than before it stood. But the wonder is to see such unimpaired vigour at four-score years of age, after a life of unwearied labour, latterly clouded by domestic calamity, and a spirit as young as ever in zeal for justice, tempered only by the mellowness which the kindly heart spreads over the fruits of the manly understanding. There wanted no testimonials of esteem from his country to consummate the venerable philanthropist's renown; yet these too have been added. Various meetings have addressed their gratulations to him. Of these the great corporation of London claims the first regard, and after presenting him with the freedom of the city, they have ordered to be erected in their hall, as a memorial of his extraordinary virtue, a likeness of the mortal form of Thomas Clarkson. * * * * * HISTORY OF THE ABOLITION OF THE SLAVE TRADE. * * * * * CHAPTER I. No subject more pleasing than that of the removal of evils.--Evils have existed almost from the beginning of the world; but there is a power in our nature to counteract them--this power increased by Christianity.--Of the evils removed by Christianity one of the greatest is the Slave Trade.--The joy we ought to feel on its abolition from a contemplation of the nature of it; and of the extent of it; and of the difficulty of subduing it.--Usefulness also of the contemplation of this subject. I scarcely know of any subject, the contemplation of which is more pleasing, than that of the correction or of the removal of any of the acknowledged evils of life; for while we rejoice to think that the sufferings of our fellow-creatures have been thus, in any instance, relieved, we must rejoice equally to think, that our own moral condition must have been necessarily improved by the change.
