A. S. D.—Wood's Illustrated Natural History, Ingersoll's Friends worth Knowing, Wolf's Wild Animals, and Jaeger's North American Insects are all excellent works on the subjects they treat. These books are published by Harper & Brothers, and are illustrated.


N. Eng F.—We can hardly blame you for feeling dissatisfied with your present position. A boy of sixteen, who is well and strong, and who has acquired a common-school education, ought to do better than remain in an office at $2 a week, with no prospect of advancement. You might learn a trade. You might, if your parents gave their consent, go West and engage in farming. You might enter a business house at the bottom, and work your way up. Whatever you do, thoroughness, honesty, and diligence are necessary to success. So is self-denial, and a steady effort to do your best every day.
