Fred C. S.—The United States government has never offered to purchase cancelled stamps.
I. U.—Sheep have front teeth, or nippers, only on the lower jaw, the upper having instead a firm fibrous pad. There are eight of these nippers in a full-grown sheep. There are six grinders, or back teeth, on each side of both the upper and lower jaws.
Edith J. P.—You will find information about gold-fish in Young People No. 6.
Zella T.—The origin of April-fools' Day is unknown. It is observed as a season of practical jokes in nearly every country. Even the Hindoos have a festival terminating on the 31st of March, during which they aim to send their friends on all manner of absurd errands, and enjoy a laugh at their disappointment. In Italy and France the victims of practical jokes of the 1st of April are called "April-fish."
B. H. T.—If you wish to keep the skin of your greyhound very soft and delicate, feed it on bread and milk, sugar, cake, crackers, and dainty food of any kind. It will eat meat fast enough, if you allow it to do so, and a little beef, cut very fine, will make it stronger and do it good. Always give it plenty of fresh water.
