Mr. Brock seized the opportunity, and bluntly asked him what the nature of the anxiety might be. Did it relate to money? No; it related to a Letter which had been waiting for him for many years. Had he received the letter? Not yet; it had been left under charge of one of the partners in the firm which had man aged the business of his inheritance for him; the partner had been absent from England; and the letter, locked up among his own private papers, could not be got at till he returned. He was expected back toward the latter part of that present May, and, if Midwinter could be sure where the cruise would take them to at the close of the month, he thought he would write and have the letter forwarded. Had he any family reasons to be anxious about it? None that he knew of; he was curious to see what had been waiting for him for many years, and that was all. So he answered the rector's questions, with his tawny face turned away over the low bulwark of the yacht, and his fishing-line dragging in his supple brown hands.

Favored by wind and weather, the little vessel had done wonders on her trial trip. Before the period fixed for the duration of the cruise had half expired, the yacht was as high up on the Welsh coast as Holyhead; and Allan, eager for adventure in unknown regions, had declared boldly for an extension of the voyage northward to the Isle of Man. Having ascertained from reliable authority that the weather really promised well for a cruise in that quarter, and that, in the event of any unforeseen necessity for return, the railway was accessible by the steamer from Douglas to Liverpool, Mr. Brock agreed to his pupil's proposal. By that night's post he wrote to Allan's lawyers and to his own rectory, indicating Douglas in the Isle of Man as the next address to which letters might be forwarded. At the post-office he met Midwinter, who had just dropped a letter into the box. Remembering what he had said on board the yacht, Mr.

Brock concluded that they had both taken the same precaution, and had ordered their correspondence to be forwarded to the same place.

Late the next day they set sail for the Isle of Man.

For a few hours all went well; but sunset brought with it the signs of a coming change. With the darkness the wind rose to a gale, and the question whether Allan and his journeymen had or had not built a stout sea-boat was seriously tested for the first time. All that night, after trying vainly to bear up for Holyhead, the little vessel kept the sea, and stood her trial bravely. The next morning the Isle of Man was in view, and the yacht was safe at Castletown. A survey by daylight of hull and rigging showed that all the damage done might be set right again in a week's time. The cruising party had accordingly remained at Castletown, Allan being occupied in superintending the repairs, Mr. Brock in exploring the neighborhood, and Midwinter in making daily pilgrimages on foot to Douglas and back to inquire for letters.

The first of the cruising party who received a letter was Allan.

"More worries from those everlasting lawyers," was all he said, when he had read the letter, and had crumpled it up in his pocket. The rector's turn came next, before the week's sojourn at Castletown had expired. On the fifth day he found a letter from Somersetshire waiting for him at the hotel. It had been brought there by Midwinter, and it contained news which entirely overthrew all Mr. Brock's holiday plans. The clergyman who had undertaken to do duty for him in his absence had been unexpectedly summoned home again; and Mr. Brock had no choice (the day of the week being Friday) but to cross the next morning from Douglass to Liverpool, and get back by railway on Saturday night in time for Sunday's service.

Having read his letter, and resigned himself to his altered circumstances as patiently as he might, the rector passed next to a question that pressed for serious consideration in its turn.

Burdened with his heavy responsibility toward Allan, and conscious of his own undiminished distrust of Allan's new friend, how was he to act, in the emergency that now beset him, toward the two young men who had been his companions on the cruise?
