“Mr. Ingersoll’s book may be heartily commended to all. It is another 
most valuable addition to that none too rapidly growing library of works deal- 
ing with the mysteries of the natural world about us, in such a charmingly 
interesting and yet scientifically accurate way that the present and cuming gen- 
erations can have no possible excuse for being, as has been too long the case, 
strangers at home.” — Afinneapolis Tribune. 
“The book is written in admirable style, with a brightness and vivacity 
often lacking in similar works. It is in all respects a must welcome book, and 
will find place on the home shelves, in the clubs, in the libraries, and among 
the treasures of the growing boy nv less.” — Connecticut Post. 
AN ISLAND IN THE AIR 
A Story of Singular Adventures in the Mesa Country 
Mlustrated with a frontispiece in colors, full-page half-tones, and many 
drawings in the text 
Cloth 12mo $1.50 
A story of real adventure on the real frontier, — the Far West of fifty years 
ago, when life was large and free, with game for the shooting ; with bears and 
wolves and cougars; with Indians and soldiers and emigrant trains, and all 
the picturesque furniture of a land of promise for healthy sport. It was neither 
sport nor romance, however, that these young people — boys and girls — were 
in search of down there on the borders of the Navajo country — they came 
because they had to. Nothing was further from their minds than to get sepa- 
rated from their elders by a strange yet perfectly natural accident, and to find 
themselves marooned upon a desert island in a sea of blue air, and then to get 
away by aid of a lot of Mokis, dead and alive. But so it happened; and 
being brave, resourceful, and jolly, the youngsters met their adventures half- 
way, acquitted themselves with credit, and so escaped from difficulties which 
might have daunted older heads and hands.
