As a proof of the comprehension of the shepherd's dog, I quote the description of Mr. St. John, in his "Highland Sports:"--"A shepherd once, to prove the quickness of his dog, who was lying before the fire in the house where we were talking, said to me, in the middle of a sentence concerning something else, 'I'm thinking, Sir, the cow is in the potatoes.' Though he purposely laid no stress on these words, and said them in a quiet, unconcerned tone of voice, the dog, who appeared to be asleep, immediately jumped up, and leaping through the open window, scrambled up the turf roof of the house, from which he could see the potato field. He then (not seeing the cow there) ran and looked into the byre [farm-yard], where she was, and finding that all was right, came back to the house. After a short time the shepherd said the same words again, and the dog repeated his look-out; but on the false alarm being a third time given, the dog got up, and wagging his tail, looked his master in the face with so comical an expression of interrogation, that we could not help laughing aloud at him, on which, with a slight growl, he laid himself down in his warm corner, with an offended air, as if determined not to be made a fool of again." Mr. Hogg, the Ettrick shepherd, is the person of all others to give an adequate idea of the shepherd's dog, and I use very nearly his own words. "My dog Sirrah, was beyond all comparison the best dog I ever saw; he was of a surly, unsocial temper; disdaining all flattery, he refused to be caressed; but his attention to my commands and interests will never again, perhaps, be equalled by any of the canine race. I thought I discovered a sort of sullen intelligence in his countenance, notwithstanding his dejected and forlorn appearance; I gave a drover a guinea for him. He was scarcely a year old, and knew so little of herding, that he had never turned a sheep in his life; but as soon as he discovered that it was his duty to do so, and that it obliged me, I can never forget with what eagerness and anxiety he learned his evolutions. He would try every way deliberately, till he found out what I wanted him to do, and when I once made him understand a direction, he never forgot or mistook it again. Well as I knew him, he often astonished me; for when pressed hard in accomplishing the task that he was put to, he had expedients of the moment, that bespoke a great share of the reasoning faculty.
