When Jarley married he turned his attention to the devising of apparatus to make domestic life less trying to Mrs. Jarley. As a bachelor he had contrived quite a number of mechanical effects which made his lonely life easier. He had fitted up his rooms with devices by means of which, while lying in bed on cold mornings, he could light his gas-stove without getting up; and his cigars, the ends of which he had dipped in sulphur, so that they could be lit by scratching them on the under side of the mantel-piece, just as matches are ignited, were the delight of his life. Now, however, he turned his mind towards helping little Mrs. Jarley on in the domestic world. He prepared a chart by means of which the monotony of marketing was done away with entirely. He also arranged for her a charming automatic curl-paper box, and drew up a plan for a patent pair of curling-tongs, which could be fastened to the gas-fixture and kept heated to the degree required, so that it might be used at a moment's notice. This was provided with a number of movable ends, all different, in order that Mrs. Jarley could, if she chose, vary the appearance of her curls according to her taste; and although the little lady never approved of it sufficiently to have it made, it was undoubtedly a valuable contrivance. Then when Jarley junior came along to delight the parent soul, self-rocking cradles and perpetual reservoirs for food were devised, and some of them put into actual use, though, as a rule, Mrs. Jarley preferred the old-fashioned methods to which she was by her home training more accustomed. The great invention of Jarley, however, was the result of his study of Jarley junior as that very charming and exceedingly agile child developed from infancy into boyhood. The idea came to him one Sunday afternoon while Mrs. Jarley was at church. It was the nursemaid's afternoon out, and Jarley had undertaken to care for Master Jarley in the absence of his true guardians. "Well, Jack," he said to his son, when they had been left in sole possession of the Jarley mansion, "you and I must entertain each other this afternoon. What shall we do?" "I'd like to play choo-choo car with you," said Jack. "I'll be the engine and you be the train." "Very well," said Jarley. "Have you got your steam up?" "Yeth," lisped Jack. "All aboard!"
