The first cause, so far as it can be determined, of the existence of this book may be found in the following letter, written by my only married sister, and received by me, Harry Burton, salesman of white goods, bachelor, aged twenty-eight, and received just as I was trying to decide where I should Spend a fortnight's vacation: - "DEAR HARRY: - Remembering that you are always complaining that you never have a chance to read, and knowing that you won't get it this summer, if you spend your vacation among people of your own set, I write to ask you to come up here. I admit that I am not wholly disinterested in inviting you. The truth is, Tom and I are invited to spend a fortnight with my old schoolmate, Alice Wayne, who, you know, is the dearest girl in the world, though you DIDN'T obey me and marry her before Frank Wayne appeared. Well, we're dying to go, for Alice and Frank live in splendid style; but as they haven't included our children in their invitation, and have no children of their own, we must leave Budge and Toddie at home. I've no doubt they'll be perfectly safe, for my girl is a jewel, and devoted to the children, but I would feel a great deal easier if there was a man in the house. Besides, there's the silver, and burglars are less likely to break into a house where there's a savage-looking man. (Never mind about thanking me for the compliment.) If YOU'LL only come up, my mind will be completely at rest. The children won't give you the slightest trouble; they're the best children in the world - everybody says so
