WAVE.--Common sunfish can not injure the gold-fish and other inhabitants of your aquarium.
OTTAWA, CANADA.
I am nine years old, and I have two sisters and one brother, Ruth, Alonzo, and baby Vera.
There was a boy who wrote to YOUNG PEOPLE and said he was very fond of history. So am I. I have read _Peter Parley's History of the United States_ five times, and now I am reading Charles Dickens's _Child's History of England_. I don't know what to read next. I wish you would tell me the names of some child's histories, for I do not understand very well those written for older people.
PERCY R.
All of Abbott's Illustrated Histories would interest you. Then there are some good histories for young readers by Miss Yonge; and child's histories of the United States, of Greece, and of Rome, by Bonner; an interesting child's history of the United States, by T. W. Higginson; and many other books referring to special periods, like Mr. Coffin's _Story of Liberty_ and _Boys of '76_, where you will find much valuable information. The works by Abbott, Bonner, and Coffin are published by Harper & Brothers.
ELLA W.--The date of the invention of gun-powder is unknown. Tradition says that it was used in China as early as A.D. 85, for fire-works and blasting, and that the Arabs employed it at the siege of Mecca in 690.
Roger Bacon is supposed to allude to its explosive force, and it is said that Berthold Schwartz, a monk, about 1336, discovered the mode of manufacturing it. It is also said that the knowledge of it was conveyed to Europe by the returning Crusaders.
Tempt your parrot with English walnuts, bits of apple and pear, and canary and hemp seed, and also give it a red pepper to pick to pieces.
Let it out of its cage to climb about an hour or more every morning. A parrot can not be healthy without some exercise.
GEORGE F.--Directions for "Model Yacht Building" were given in YOUNG PEOPLE No. 23.
F. H. L.--Any hardware merchant will send to New York city for a catalogue of toy steam-engines for you, which will give you full information in regard to styles, prices, and how and where the engine you require can be obtained.
FRED H. H.--You can purchase turtles at any store where gold-fish and materials for an aquarium are sold. They will cost you very little--ten or fifteen cents apiece, perhaps, for small ones. If you are going to the country, you can catch plenty of them yourself. By reading former numbers of Our Post-office Box you will find many directions for the care of turtles. A water turtle needs clean water, and also stones to climb up on.
