But watch one of those drovers, after his cattle are safely penned, blow off the foam from a full pot of porter and drink. You can fairly trace the current outside his ruddy throat, as gulp after gulp goes down, long, deep, and vast; you wonder how ever the fellow can hold his breath. If he does not empty the whole pot at a draught, he will not leave enough in the bottom to drown a fly. He brought in his throat the dust of many a weary mile; and, when you recal the shouting and hallooing which is so necessary in driving his cattle, you marvel not that he feels as thirsty as a lime-burner. Nor does his dog lose a moment before he visits the adjoining cab-stand, where he makes friends with the waterman, and, like his master, quenches his thirst. No dogs are more sagacious than those which have been well trained by a Smithfield drover--a look or a motion is sufficient to direct them: they need no telling to drive the sheep aside when a vehicle is passing; a runaway needs no pointing out to them, they are up and over the backs of the whole flock in a moment; and, having placed the deserter again in marching order, the side of the master is once more their post. As they look into his face, you might, from their actions, fancy that they read his very thoughts, and foresaw his wishes. Many of these men love their dogs as dearly as their children; and well do the faithful animals return such affection. We have seen a drover asleep on the pavement in summer, with his dog coiled up beside him, and ready to spring upon the first assailant who could be found bold enough to disturb his owner's slumber. The watchfulness of the dog and the attitude of the sleeper would have delighted the eye of Landseer.
