This volume collects two classic (and rarely seen) novels with cryptozoological and 'lost world' elements.
Last of the Mammoths (1907; translated from the French) is a scientific romance. A young French artist, Raoul Le Fort, has fallen in love with Eva, the beautiful daughter of an American millionaire, the Hon. John N. Corliss. Corliss isn't impressed with the Le Fort's bohemian lifestyle or his disdain for commerce, but he sees an opportunity to finish his personally-funded natural history museum with its crowning glory. Le Fort is given a quest, to bring back the bones of a giant mammoth from the tundra, and he will win the hand of Eva. Le Fort accepts, then finds that he has a rival for Eva's hand (and fortune) who is also tasked to find a mammoth skeleton. A grueling trip is in store. And what about those native stories of a monstrous creature in the Great North that destroys all who venture across its path?
Men of the Mist (1922) is a boy's adventure novel. Clem and Billy Ballard are stuck in a Dickensian nightmare of a boys' school until a surprise journey is thrust upon them. Traveling to North America and across the continent, they then embark on a rugged trip north with new friends and dangerous enemies across a region that doesn't suffer tenderfoot mistakes for long. Encountering strange beasts and natural wonders, they are in for a greater surprise at their destination . . .
