The descriptions of the several species have been prepared with great care and present several advantages over those in other books. They are short and so expressed that they may be recalled readily while looking at the bird. They are thus especially adapted for field use. The illustrations were drawn especially for this work. Their number, scientific accuracy, and careful execution add much to the value and interest of the book. The general Key to Land and Water Birds and a very full index make the book convenient and serviceable both for the study and for field work. _Apgar's Birds of the United States will be sent, prepaid, to any address on receipt of the price by the Publishers:_ American Book Company NEW YORK .
