Desmond had been on the train but a few minutes really when he observed a tall, country-looking young fellow, who fixed his eyes on him. As has been demonstrated all through our narrative, Desmond was a very quick, discerning chap; in the language of the day, he was "up to snuff," and the instant he caught the eye of the country-looking fellow he knew that something was up, and he discerned more which will be disclosed as our narrative advances. Desmond had not boarded a through train; he was to go to a large town where he would meet a through express. The train he had entered was a way train, and he seated himself by the window. No one was in the seat with him at first, but soon the country-looking chap took a seat beside him. The latter appeared to be a jolly, innocent sort of chap, and he addressed the young adventurer with the words: "Hello!" There came a merry gleam in Desmond's eyes, as he asked: "Do you take me for a telephone?" The stranger arched his eyebrows, and demanded: "A telephone?" "Yes." "What makes you ask that question?" "Because you yelled 'hello' in my ear." "I've heard about telephones, but I never saw one." "You never did?" "No; what are they like?" The question was asked seemingly in the most innocent manner, but the keen-witted Desmond's suspicions were at once aroused, and on the instant he made a curious discovery. The fellow was a make-up, under a disguise, and consequently under immediate suspicion also. "So you never saw a telephone?" "Never." "You _tell_ me that?" "Yes." Our hero knew he had a long journey before him; he was naturally very fond of a joke and excitement, and besides he had instinctive hatred for designing men. Our hero was aware that the trains, as a rule, are infested with sharps, and the efforts of the railroad companies to squelch these nuisances are not altogether successful. Our adventurer determined to have a little amusement, and if his suspicions were fully verified he was resolved to teach at least one sharp a good lesson. We will repeat, Desmond did not look like an athlete or a youth who had seen the rough side of life; he could easily be mistaken for an ordinarily bright youth who had much to learn. "So you really never saw a telephone?" "Never," repeated the man. Desmond, having determined upon his course of action, assumed a most serious air, and with the greatest earnestness graphically described a telephone, and the stranger appeared to be all interest and attention, and expressed his surprise by innocent ejaculations, as our hero related the wonderful possibilities of the telephone. It was an amusing scene, or would have been to one who was under the rose and understood that a game was being played. When Desmond's description apparently, as stated, told in the most earnest manner the sharp, as we shall call him, said:
