Like a bad daguerreotype, great part of it has been entirely lost; I can tell you nothing about the beginning and nothing about the end; but the doings of some fifty or sixty hours about the middle remain quite distinct and definite, like a little patch of sunshine on a long, shadowy plain, or the one spot on an old picture that has been restored by the dexterous hand of the cleaner. I remember a tale of an old Scots minister called upon suddenly to preach, who had hastily snatched an old sermon out of his study and found himself in the pulpit before he noticed that the rats had been making free with his manuscript and eaten the first two or three pages away; he gravely explained to the congregation how he found himself situated: “And now,” said he, “let us just begin where the rats have left off.” I must follow the divine’s example, and take up the thread of my discourse where it first distinctly issues from the limbo of forgetfulness.
