We have specially mentioned the question of Union, because of late years Dr. Buchanan has closely and completely identified himself with it, and he is pledged to see it carried through. He has made eloquent and effective speeches in favour of Union at almost every meeting of the General Assembly held since it was brought on the _tapis_; and only last year he opened the debate in an address that has seldom been equalled for sound argument and rhetorical effect. It would be superfluous to make any selections or quotations from the rev. gentleman's speeches on this subject; his views are already well known to all who take an interest in the cause for which he pleads, and before that cause has reached its final consummation it is more than likely that he will again be at Ephesus, fighting on its behalf. The soundness of his judgment and the eminently dispassionate views which he is able to take of all questions laid before him are so fully recognised by his brethren in the Free Church that Dr. Buchanan is consulted on nearly every matter that relates to the welfare of that body. He can discriminate so nicely and so fairly on the merits of any one question submitted for his adjudication--his judicial faculty is so highly developed, that some of those who know him best have hazarded the prediction that, had he been trained for the bar instead of for the pulpit, he would by this time have held the position of Lord President of the Court of Session. Dr. Buchanan is a man of such varied gifts and accomplishments that he would have shone in any sphere, and in the interests of Christianity it is a source of congratulation rather than otherwise that he chose the pulpit for his profession. In this connection we may mention the fact that Dr. Buchanan has spoken at many public meetings of a moral, social, and political, as well as of an ecclesiastical character. One of his last appearances on the City Hall platform was on the occasion of a meeting held last year to take measures for providing additional church accommodation in Glasgow--a desideratum for which he has often and eloquently pleaded. As an author, Dr. Buchanan's name will be handed down to posterity--at least so far as his own church is concerned. His "Ten Year's Conflict" is the only complete and authoritative record of the causes and effects of the Disruption that has yet been published. He has also published an able and scholarly work on the "Ecclesiastes;" while his leisure hours on a holiday tour in the Mediterranean have been turned to advantage by his publication of an interesting volume entitled "Clerical Furlough."
