As the clerk observed the name of the gentleman on the card, and saw Mr. Cursty Sandboys prepare to write a similar title in the Autograph Book, he remembered that this was the very appellation of the individual who had been detected, a few days back, in abstracting a silver-handled stiletto from one of the counters in the interior. Before the lady had time to insert her autograph in the official register, the clerk begged to be excused, saying he was called away upon important business; and, proceeding to some of his brother officials, he informed them that the impudent thief Cursty Sandboys had dared to seek admission at the Crystal Palace once more. In an instant, the news that the expert Cursty Sandboys, the pickpocket, was about to enter the building, spread throughout the Crystal Palace, literally with the rapidity of lightning, for the electric telegraph was immediately set to work, telling the officials, one and all, to— BEWARE OF CURSTY SANDBOYS! No sooner did the alarming intelligence become general among the authorities, than many, anxious to obtain a peep at the singularly-named “swell-mobsman,” congregated round the entrance, where he was still standing, and the innocent Christopher could observe them nudging one another, and whispering, evidently concerning himself, in a way that he did not half like, and could not possibly understand. The clerk, on his return, proceeded to compare the signature of the present Mr. Sandboys with that of the individual who had made his appearance on the day of the opening. Observing an evident discrepancy between the two, he beckoned a brother-official to his side, and immediately they both set to work, contrasting the one signature with the other, and looking backwards and forwards in the most mysterious manner at the unoffending Mr. Sandboys. Christopher, who got more and more bewildered at the manner of the officials, could not for the life of him comprehend what it all meant. At length, however, he heard one of the dozen policemen, who were now grouped close round about him, whisper to another at his elbow that he, Mr. Sandboys, had shaved off his moustachios, while another-officer put his lips close to the ear of a brother official, and said, in an under tone, that he had left his beard behind him. In an instant the telegraph was at work, communicating the fact to the authorities at each end of the building, and informing them that Cursty Sandboys had come close shaved on the present occasion, and instructing them one and all to keep a sharp eye upon his movements.
