"Mr. Allen's text, as in all his writings, is singularly picturesque and captivating. There are no commonplaces, and, although the outcome is perfectly evident early in the story, the reader will find his attention chained.... It is one of the best of the summer books, and as an artistic bit of light reading ranks high. It is a pity that such a vivid imagination and high-bred style of discourse are no longer in the land of the living to entertain us with further stories of adventure."--_Boston Times._ THE SECRET OF THE CRATER (A Mountain Moloch.) By Duffield Osborne, author of "The Spell of Ashtaroth," etc. "The author is a novelist with a genuine gift for narrative. He knows how to tell a story, and he is capable of conceiving a plot as wild as was ever imagined by Jules Verne or Rider Haggard.... The reader will find himself amused and interested from the first page to the last."--_N. Y. Herald._ End of Project Gutenberg's Dwellers in the Hills, by Melville Davisson Post
