"Heaven grant that when next my Cousin of Scotland sends an ambassador, he choose another man," said the King, and there was not a soul in all the palace who did not breathe a fervent "Amen."

Meanwhile, Sir Michael and his wonderful steed were speeding along on their homeward way. They had crossed the north of France, and were flying over the Straits of Dover, when the creature began to think that it might work a little mischief on its own account.

It had taken a sudden fancy to remain in France for a while, and it thought how nice it would be if it could pitch its master, whom it rather feared than loved, over its head into the water, and so be rid of him for ever.

It knew that as long as it was under his spell, it had to do his bidding, but it knew also that there were certain words which could break the spell even of a wizard, and it began to wonder if it would be possible to make Sir Michael pronounce one of these.

"Master," it said at last slyly, for when it wanted it had the power of speech, "I know little about Scottish ways, but I have oft-times been told that the old wives and children there mutter some words to themselves ere they go to bed. 'Tis some spell, I warrant, and I would fain know it. Canst tell me the words?"

Now the wily animal knew perfectly well what words the children of Scotland were taught to repeat as they knelt at night at their mother's knee, but it hoped that its master would answer without thinking.

But Sir Michael had not studied magic for long years for nothing, and he knew that if he answered that the women and children in Scotland bowed their knees and said their Pater Noster ere they went to bed, the holy words would break the spell, and he would be at the mercy of the fiend, who, when he needed him, was obliged to take the form of a horse, or serve him in any other way which he required.

So he shook the creature's bridle and answered sharply, "What is that to thee, Diabolus? Attend to the business thou hast in hand, and vex not thy soul with silly questions. If thou truly desirest to know what the bairns are taught to say at bed-time, then I would advise thee, when thou art in Scotland, and hast time to spare from thy wicked devices, to go and stand by a cottage window, and learn for thyself. Mayhap the knowledge will do thee good. In the meantime think no more of the matter, unless thou wouldst feel the weight of my wand on thy flanks."

Now, if there was one thing which the great horse feared, it was the wizard's magic wand, so he put his mind to his work, and flew with all the swiftness he possessed northwards over England, and across the Cheviots, until at last they came in sight of Edinburgh, and the Royal Palace of Holyrood.

Here Sir Michael slid from his back, and dismissed him with a little wave of his wand. "Avaunt, Diabolus," he said, and at the words the magic horse vanished into thin air, and, strange to say, the black cloak and hairy cap which the wizard had worn on the journey seemed to fall from him and vanish also, and he was left standing, a middle-aged, dignified gentleman, clad in a suit of sober brown.
