The first point which he contrived to establish clearly in his mind was that the person who signed the name of Robert Chennery was desirous of examining a plan, or printed account, of the north side of the interior of a certain old house in Cornwall, called Porthgenna Tower. The second point appeared to resolve itself into this, that Robert Chennery believed some such plan or printed account might be found among the collection of books belonging to Mr. Treverton. The third point was that this same Robert Chennery would receive the loan of the plan or printed account as one of the greatest favors that could be conferred on him. Meditating on the latter fact, with an eye exclusively fixed on the contemplation of his own interests, Shrowl arrived at the conclusion that it might be well worth his while, in a pecuniary point of view, to try if he could not privately place himself in a position to oblige Robert Chennery by searching in secret among his master's books. "It might be worth a five-pound note to me, if I managed it well," thought Shrowl, putting the letter back in his pocket again, and ascending the stairs thoughtfully to the lumber-rooms at the top of the house.

These rooms were two in number, were entirely unfurnished, and were littered all over with the rare collection of books which had once adorned the library at Porthgenna Tower. Covered with dust, and scattered in all directions and positions over the floor, lay hundreds and hundreds of volumes, cast out of their packing-cases as coals are cast out of their sacks into a cellar. Ancient books, which students would have treasured as priceless, lay in chaotic equality of neglect side by side with modern publications whose chief merit was the beauty of the binding by which they were inclosed. Into this wilderness of scattered volumes Shrowl now wandered, fortified by the supreme self-possession of ignorance, to search resolutely for one particular book, with no other light to direct him than the faint glimmer of the two guiding words—Porthgenna Tower. Having got them firmly fixed in his mind, his next object was to search until he found them printed on the first page of any one of the hundreds of volumes that lay around him. This was, for the time being, emphatically his business in life, and there he now stood, in the largest of the two attics, doggedly prepared to do it.

He cleared away space enough with his feet to enable him to sit down comfortably on the floor, and then began to look over all the books that lay within arm's-length of him. Odd volumes of rare editions of the classics, odd volumes of the English historians, odd volumes of plays by the Elizabethan dramatists, books of travel, books of sermons, books of jests, books of natural history, books of sport, turned up in quaint and rapid succession; but no book containing on the title-page the words "Porthgenna Tower" rewarded the searching industry of Shrowl for the first ten minutes after he had sat himself down on the floor.

Before removing to another position, and contending with a fresh accumulation of literary lumber, he paused and considered a little with himself, whether there might not be some easier and more orderly method than any he had yet devised of working his way through the scattered mass of volumes which yet remained to be examined. The result of his reflections was that it would be less confusing to him if he searched through the books in all parts of the room indifferently, regulating his selection of them solely by their various sizes; disposing of all the largest to begin with; then, after stowing them away together, proceeding to the next largest, and so going on until he came down at last to the pocket volumes. Accordingly, he cleared away another morsel of vacant space near the wall, and then, trampling over the books as coolly as if they were so many clods of earth on a ploughed field, picked out the largest of all the volumes that lay on the floor.

It was an atlas; Shrowl turned over the maps, reflected, shook his head, and removed the volume to the vacant space which he had cleared close to the wall.

The next largest book was a magnificently bound collection of engraved portraits of distinguished characters. Shrowl saluted the distinguished characters with a grunt of Gothic disapprobation, and carried them off to keep the atlas company against the wall.

The third largest book lay under several others. It projected a little at one end, and it was bound in scarlet morocco. In another position, or bound in a quieter color, it would probably have escaped notice. Shrowl drew it out with some difficulty, opened it with a portentous frown of distrust, looked at the title-page—and suddenly slapped his thigh with a great oath of exultation. There were the very two words of which he was in search, staring him in the face, as it were, with all the emphasis of the largest capital letters.

He took a step toward the door to make sure that his master was not moving in the house; then checked himself and turned back. "What do I care," thought Shrowl, "whether he sees me or not? If it comes to a tustle betwixt us which is to have his own way, I know who's master and who's servant in the house by this time." Composing himself with that reflection, he turned to the first leaf of the book, with the intention of looking it over carefully, page by page, from beginning to end.

The first leaf was a blank. The second leaf had an inscription written at the top of it, in faded ink, which contained these words and initials: "Rare. Only six copies printed. J. A. T." Below, on the middle of the leaf, was the printed dedication: "To John Arthur Treverton, Esquire, Lord of the Manor of Porthgenna, One of his Majesty's Justices of the Peace, F.R.S., etc., etc., etc., this work, in which an attempt is made to describe the ancient and honored Mansion of his Ancestors—" There were many more lines, filled to bursting with all the largest and most obsequious words to be found in the dictionary; but Shrowl wisely abstained from giving himself the trouble of reading them, and turned over at once to the title-page.

There were the all-important words: "The History and Antiquities of Porthgenna Tower. From the period of its first erection to the present time; comprising interesting genealogical particulars relating to the Treverton family; with an inquiry into the Origin of Gothic Architecture, and a few thoughts on the Theory of Fortification after the period of the Norman Conquest. By the Reverend Job Dark, D.D., Rector of Porthgenna. The whole adorned with Portraits, Views, and Plans, executed in the highest style of art. Not published. Printed by Spaldock and Grimes, Truro, 1734."
