William Wallace Cook, East of Sunrise (1926)
“ CHAPTER III. SPRINGING A SENSATION. THE sheriff at Tres Alamos, Jerry Blake, had a name for men like Red Galloway and Eph Springer. He called them “grubbers.” Grubbers are the hobos of the desert country, but they go the ordinary tramp one better. Although their wanderings may be aimless, their purposes have a set direction. Any man who can be begged or cajoled into giving them a grubstake is their quarry. ”
