"A designing old villain!" he exclaimed at length, and Gammon agreed with him; but strange to say, with all his acuteness, never adverted to the real cause of Quirk's sudden and vehement exclamation. When Gammon told him of the manner in which he had opened Titmouse's eyes to the knavery of Tag-rag, and the expedient he had suggested for its complete demonstration to Titmouse, Quirk could have worshipped Gammon, and could not help rising and shaking him very energetically by the hand, much to his astonishment. After a long consultation, they determined to look out fresh lodgings for Titmouse, and remove him presently altogether from the company and influence of Tag-rag. Some time after they had parted, Mr. Quirk came with an eager air into Mr. Gammon's room, with a most important suggestion; viz. whether it would not be possible for them to get Tag-rag to _become a surety_ to them, by and by, on behalf of Titmouse? Gammon was delighted!--He heartily commended Mr. Quirk's sagacity, and promised to turn it about in his thoughts very carefully. Not having been let entirely into Quirk's policy, (of which the reader has, however, just had a glimpse,) Mr. Gammon did not see the difficulties which kept Quirk awake almost all that night; viz. how to protect Titmouse from the machinations of Tag-rag and his daughter, and yet keep Tag-rag sufficiently interested in, and intimate with, Titmouse, to entertain, by and by, the idea of becoming surety for him to them, the said Messrs. Quirk, Gammon, and Snap; and--withal--how to manage Titmouse all the while, so as to forward their objects, and also that of turning his attention towards Miss Quirk; all this formed really rather a difficult problem!--Quirk looked down on Tag-rag with honest indignation, as a mean and mercenary fellow, whose unprincipled schemes, thank Heaven! he already saw through, and from which he resolved to rescue his innocent and confiding client, who was made for better things--_to wit, Miss Quirk_. When Titmouse rose the next morning, (Saturday,) behold--he found his hair had become of a variously shaded purple or violet color! Astonishment and apprehension by turns possessed him, as he stared into the glass, at this unlooked-for change of color; and hastily dressing himself, after swallowing a very slight breakfast, off he went once more to the scientific establishment in Bond Street, to which he had been indebted for his recent delightful experiences. The distinguished inventor and proprietor of the Cyanochaitanthropopoion was behind the counter as usual--calm and confident as ever. "Ah! I see--as I said! as I said!" quoth he, with a sort of glee in his manner. "Isn't it?--coming round quicker than usual--Really, I'm selling more of the article than I can possibly make."
