"I am going to tell you about that," said Time. "You must not remain too long locked up in anybody. Here is a curious tiny clock, with a little gold key, and you must take them with you and be very careful of them. Whenever you find that you have passed into somebody else, you must at once wind up your clock and hang it somewhere so that you can see it as you go about. The clock will go for a month, and as soon as it runs down and stops, you will be changed back into your separate self again. A month will be long enough for you to live in each person." "Oh, thank you, thank you," cried Pet, seizing the clock. "One thing you must be sure not to forget," said Time, "so attend to me well. There is a mysterious sympathy between you and the clock and the little gold key, and if you lose the key after the clock is wound up the clock will go on forever, or at least until you find the key again. So if you do not want to be shut up in somebody to the end of your life, be careful to keep guard of the key." "That I will," said Pet. "And now, good-by," said Time. "You can go on at this sort of thing as long as you like--until you are quite grown up, perhaps; and you couldn't have a better education." Conclusion next month. Useful Knowledge KNIVES and forks with ivory, bone or wooden handles should not be put into cold water. But we suggest that when our readers buy knives for the table they get those with silver-plated handles and blades. They need no bath brick to keep them bright, but only an occasional rub with whiting, and save "lots of trouble." LEMON PIE.--One cup of hot water, one tablespoonful of corn starch, one cup of white sugar, one tablespoonful of butter, the juice and grated rind of one lemon. Cook for a few minutes, add one egg, and bake with a top and bottom crust. STRAWBERRY SHORTCAKE.--One quart of flour sifted dry, with two large teaspoonfuls of baking powder, one tablespoonful of sugar, and a little salt. Add three tablespoonfuls of butter and sweet milk, enough to form a soft dough. Bake in a quick oven, and when partially cooked split open, spread with butter, and cover with a layer of strawberries well sprinkled with sugar; lay the other half on top, and spread in the same manner. A GOOD WAY TO USE COLD MEAT.--Take the remnants of any fresh roasted meat and cut in thin slices. Lay them in a dish with a little plain boiled macaroni, if you have it, and season thoroughly with pepper, salt, and a little walnut catsup. Fill a deep dish half full; add a very little finely chopped onion, and pour over half a can of tomatoes or tomatoes sliced, having previously saturated the meat with stock or gravy. Cover with a thick crust of mashed potato, and bake till this is brown in a not too hot oven, but neither let it be too slow.
