[From Books and You, Doubleday, Doran & Co., 1940, pp. 35-36:]

I suppose it is universally acknowledged that Boswell's The Life of Samuel Johnson is the greatest biography in the language. It is a book that you can read with profit and pleasure at any age. You can pick it up at any time, opening it at random, and be sure of entertainment. But to praise such a work at this time of day is absurd. I should like, however, to add to it a book that, to my mind undeservedly, is less well known. This is Boswell’s The Journal of a Tour to the Hebrides. The purchase by Colonel Isham of the Boswell manuscripts has resulted in a new and unexpurgated edition of it, for, as I suppose everyone knows, Boswell’s manuscript was edited by Malone, who thought it proper to tone it down in accordance with the primly elegant taste of the day, and so left out much that gave the book flavour. It enlarges your knowledge both of Johnson and of Boswell, and if it increases your love and admiration for the sturdy old doctor, it adds also to your respect for his poor biographer who has been so much abused. This is not a writer to be despised who had such a quick eye for an amusing incident, so much appreciation of a racy phrase, and such a rare gift for reproducing the atmosphere of a scene and the liveliness of a conversation.
