O. W. S.—We can give you no information in regard to the offer you inquire about, as we never heard of it.
Fred W.—The subscription price of Harper's Monthly, Weekly, and Young People, to one address, for one year, is eight dollars and fifty cents.
F. F.—We can not tell you what to buy for your mother's Christmas present, for we do not know as well as you, who are near her, what kind of a present would please her the best. But we would advise you to think very carefully, and if you can remember any pretty thing she has expressed a wish for, or any little comfort which you suspect she has gone without in order that she might get something for you, try to give her that. Do not spend your money for a trinket, but get something pretty and useful at the same time, like a handsome work-basket or a soft worsted breakfast shawl, and every time mamma uses it she will be sure to remember her little girl's loving thoughtfulness much more tenderly than if you give her vases or other parlor ornaments which will be stood away on the mantel-piece.
W. S. Hutchinson, William L. Betton, G. A. J., and Others.—You can get a very good illustrated catalogue of postage stamps by sending twenty-five cents to Scott & Co., 146 Fulton Street, New York city.
Hattie Kerr.—If you keep your crabs well fed with bits of raw beef or raw fish, never allowing them to get hungry, they will be more likely to leave the other inhabitants of your aquarium in peace.
