The old Harper knew it at once, and, quick as thought, he loosed it, and, drawing the halter which he had brought with him out of his stocking, he slipped it over its head.
Then he loosed his own old gray mare, and tied the end of the halter to her tail, so that, wherever she went, the brown horse was bound to follow. He chuckled to himself as he led the two animals out of the stable and across the courtyard, to the great wrought-iron gate, and when he had opened this, he let the gray mare go, giving her a good smack on the ribs as he did so. And the old gray mare, remembering her little foal shut up in the stable at home, took off at the gallop, straight across country, over hedges, and ditches, and walls, and fences, pulling the King's brown horse after her at such a rate that he had never even a chance to bite her tail, as he had thought of doing at first, when he was angry at being tied to it.
Although the mare was old, she was very fleet of foot, and before the day broke she was standing with her companion before her master's cottage at Lochmaben. Her stable door was locked, so she began to neigh with all her might, and at last the noise awoke the Harper's wife.
Now the old couple had a little servant girl who slept in the attic, and the old woman called to her sharply, "Get up at once, thou lazy wench! dost thou not hear thy master and his mare at the door?"
The girl did as she was bid, and, dressing herself hastily, went to the door and looked through the keyhole to see if it were really her master. She saw no one there save the gray mare and a strange brown horse.
"Oh mistress, mistress, get up," she cried in astonishment, running into the kitchen. "What do you think has happened? The gray mare has gotten a brown foal."
"Hold thy clavers!" retorted the old woman; "methinks thou art blinded by the moonlight, if thou knowest not the difference between a full-grown horse and a two-months'-old foal. Go and look out again and bring me word if 'tis not a brown horse which the mare has brought with her."
The girl ran to the door, and presently came back to say that she had been mistaken, and that it was a brown horse, and that all the neighbours were peeping out of their windows to see what the noise was about.
The old woman laughed as she rose and dressed herself, and went out with the girl to help her to tie up the two horses.
"'Tis the silly old Harper of Lochmaben they call him," she said to herself, "but I wonder how many of them would have had the wit to gain a new horse so easily?"
