A pleasant breeze had sprung up, so there was no rowing to do on the homeward voyage. Mr. Adiesen was steering, and Aunt Osla was napping, rolled up in shawls. Mr. Neeven had unbent considerably during the day, and was talking to his cousin with an unusual degree of cheerfulness. The Harrison boys were amusing themselves over a wooden puzzle which Harry Mitchell had invented and given them. Thus Yaspard and his sister could talk confidentially together without being overheard. He was as eager to tell her of the new project as she was to listen, and before long they had not only discussed the Yarl's scheme, but had built on it a vast structure of romantic adventure.

"It has been the very happiest of days, this," said Signy when they reached the quay; "but even happiness makes one tired, and so I am glad to be home. I shall be asleep like winkie as soon as I get into bed."

"Not so your roving brother," quoth Yaspard; "I have other things to do than sleep," and he grimaced at Lowrie, who grinned back a perfect understanding of the mysterious allusion; but Signy by that time was too sleepy to pay further attention, so followed Miss Adiesen to Moolapund, and was soon resting in dreamless repose in her own room.

Meanwhile Yaspard and the Harrisons politely offered to row the Osprey to the head of the voe with Mr. Neeven, and he—with less than his usual sharp suspicion—agreed. He even thanked them as he stepped ashore, and he strode up the hill without once looking back. If he had done so he would have seen that the boat did not pass beyond the Hoobes, but stopped near there, where the old water-mill was located by the side of a burn whose spring was far up the hill-side. They fastened the boat, and went into the mill-house, where a quantity of last year's straw and chaff was heaped. On this the three lads flung themselves and were soon fast asleep. And there the Harrisons would have slept on till breakfast time if Yaspard had not roused them shortly after midnight.

"Up, boys, up!" he said, as he shook himself. "It is high time we were off; and I hope fule-Tammy is as sound asleep now as you have been for the last five minutes."

From that mention of Tammy you will guess that another raid on Trullyabister was proposed. The fact was, Yaspard had made one quiet visit to the old ruin by himself, and had found that the things they secreted in the old chimney had disappeared. From a remark of Tammy's, Lowrie had concluded that the "natural" had discovered their hiding-place, and had abstracted the articles in question. It would have been a simple matter to ask the truth and claim the property, but that course was not the one a Viking-boy was at all likely to approve. Hence the present "lark."

The three conspirators were not long in reaching the old Ha'house, and as the back door was never locked, they easily gained admission.

Tammy slept in a small chamber beside the kitchen, and at a distance from the rooms inhabited by his master, therefore the lads were not much afraid of being heard even if the recluse had not gone to sleep.

But Gaun Neeven was asleep, and so was Tammy, "like a top, and snoring too like one," whispered Yaspard as he led the way. Tammy did not even move when they gently and deftly tied his hands together, and put a not uncomfortable gag over his mouth, and he only snored a little louder, but did not wake, when they lifted him up. (Tammy always went to bed with a complete suit of clothes on, which he kept for the purpose, saying he did not see why a "puir body" should not be as decently clothed all night as all day.) They carried him to the ruined apartment with which we are already acquainted. I ought to have mentioned that Yaspard had provided masks for himself and his companions. These were made of brown paper, painted to resemble tatooed savages, and had been put on as they came up from the mill, so that Tammy should not recognise his assailants.

But Tammy was far more cute in many ways than he got credit for being; and though astonished when the cool air and a few gentle shakes woke him up, he was not frightened by the hideous visages; even the feigned voices did not deceive him. But he was wise enough to pretend ignorance of their identity, and stared a well-acted credulity.
