Published in 1909, Paine wrote fiction, humor, verse and edited several magazines, but his outstanding work was a three-volume biography of Mark Twain, with whom he lived and traveled for four years. This is the life of the most famous Texas Ranger of the time, the man who said he would charge hell with a bucket of water. For a number of years he was deputy sheriff, or deputy marshall, or representative of the cattlemen’s associations, employed by them to put a stop to cattle stealing and robbery under arms, and served for 20 years in the Texas Rangers.
