Our comfortably-seated audiences, while viewing pictures of lands taken in various quarters of the globe, and of wild and ferocious animals prowling about their native haunts, probably seldom realize the dangers and hardships which are encountered by the men who have traveled thousands of miles to get them.”

“Count me out of such adventurous proceedings, too,” said Dave.
