knows how to come down the wind on his quarry keeping to the depressions and ravines so that not a taint of his presence is blown to the prey; and he will skulk across an open plain, stealing from hollow to hollow and stalking from bush to bush, so that the wariest are taken by surprise. As for Black Bart, he knew the kind of going which the stallion liked as well, almost, as he knew his own preferences, and he picked out a course which a surveyor with line and spirit-level could hardly have bettered. He wove across the country in loosely thrown semicircles, and came back in view of the master at the proper point. There was hardly much point in such industry in a country as smooth as this, not much more difference, say, than the saving of distance which the horse makes who hugs the fence on the turn and on account of that sticks his head under the finish wire a nose in front; and Bart clung to his work with scrupulous care.
Sometimes he ran back with lolling, red tongue, when the course lay clear even to the duller sense of a human, and frisked under the nose of Satan until a word from Barry sent him scurrying away like a pleased child. His duties comprehended not only the selection of the course but also an eagle vigilance before and behind, so that when he came again with a peculiar whine, Barry leaned a little from the saddle and spoke to him anxiously.
“D'you mean to say that they been gainin' ground on us old boy?”
