I ain’ never spoke ter a human sence we lef’ Fredericksburg. In de daytime we hide somewh’yar by de road an’ sleep, an’ we trabbel mos’ all night. ’Twas de full o’ de moon, an’ I see dem tracks jes same as ’twas in daytime. Den, arter I los’ ’em, dis heah dog, he jes keep de road hisse’f--an’ here I is.”
