Nor had it long to wait.
Presently the bell at the tiny chapel down by the lake began to ring, and immediately the postern opened, and a bevy of fair maidens came laughing out, books in hand, on their way to the morning Mass. They were all beautiful, but the gay gos-hawk had no difficulty in telling which was his master's love, for the Lady Katherine was the fairest of them all, and, as soon as he saw her, he began to sing as though his little throat would burst, and all the maidens stood still for a moment and listened to his song.
When they returned from the little chapel he was still singing, and when Lady Katherine went up into her chamber the song sounded more beautiful than ever. It was a strange song too, quite unlike the song of any other bird, for first there came a long soft note, and then a clear distinct one, and then some other notes which were always the same, "Your love cannot come here; your love cannot come here." So they sounded over and over again, in Lady Katherine's ears, until the roses on her cheeks disappeared, and she was white and trembling.
"To the dining-hall, maidens; tarry not for me," she said suddenly. "I would fain be alone to enjoy this lovely song." And, as the fresh morning air had made them all hungry, they obeyed her without a moment's thought.
As soon as she was alone she ran to the window and opened it, and there, just outside, sat a gay gos-hawk, with the most beautiful plumage that she had ever seen.
"Oh," she cried faintly, "I cannot understand it; but something in my heart tells me that you have seen my own dear love."
Then the gay gos-hawk put his head on one side, and whistled a merry tune; then he looked straight into her eyes and sang a low sweet one; then he pecked and pecked at one of his wings until the tender-hearted little lady took hold of him gently to see if he were hurt, and who can describe her delight and astonishment when she found a tiny letter from Lord William tied in a little roll under his wing.
The letter was very sad, and the tears came into her eyes as she read it. It told her how he had already sent her three letters which had never reached her, and how he felt as if he must soon die, he was so sick with longing for her.
When she had read it she sat for a long time thinking, with her face buried in her hands, while the gay gos-hawk preened his feathers, and crooned to himself on the window sill. At last she sprang to her feet, her eyes flashing and her mouth set determinedly. Taking a beautiful ring from her hand, she tied it with trembling fingers under the bird's wing where the letter had been.
"Tell him that with the ring I send him my heart," she whispered passionately, and the gay gos-hawk just gave one little nod with his head, and then sat quite still to hear the rest of her message. "Tell him to set his bakers and his brewers to work," she went on firmly, "to bake rich bridal cake, and brew the wedding ale, and while they are yet fresh I will meet him at the Kirk o' St Mary, the Kirk he hath so often told me of."
