"Um! makes a fellow's mouth water just to see 'em," declared Mark. "And there's Bruno chained up to his kennel back by the barns. What a big dog he is – a Siberian wolf hound the colonel calls him. I don't believe I'd like to meet Bruno on a dark night, and running loose."
"Oh, he isn't a bad kind at all," remarked Elmer. "I've patted him on the head often, of course when the colonel was along. He gets loose once in a while, too, but was never known to attack anybody, though if a thief tried to enter, and he was free at the time, he might jump on him and hold him. That happened once, so the colonel told me, when he lived outside of New York City."
"Well, here we are at the house," observed Mark. "Come along with me, Elmer."
"Think I'd better, when he only wanted to see you?" asked his chum, dubiously.
"Yes, come along," Mark insisted. "I don't know how it is, but I've just got a hunch that I'd like to have you with me. And the colonel is so fond of you he'll be glad you've come."
Thus urged Elmer also jumped from the vehicle.
"Jes' leab dem packages dar, 'case I 'spect tuh dribe yuh bofe back tuh town agin arter yuh done seein' de kunnel," said Sam. "An' sense de door am open, p'raps yuh bettah jes' go long tuh de library, whar de kunnel am asittin'."
"That's the ticket; come along, Elmer."
In this spirit, then, the two boys quickly reached the door of the library, a room which Elmer knew very well, as he had spent many a pleasant evening there. Mark knocked lightly on the door.
"Enter!" said a voice, which they knew belonged to the master of the mansion.
At seeing two lads the colonel's eyebrows went up, and he glanced sharply from one to the other in a questioning way. So Elmer thought it only right that he should explain.
"We were walking home together when Sam gave your message, colonel," he said, "and so I took the liberty of coming with my chum Mark."
The elderly gentleman smiled. Elmer was a favorite of his, and he had taken a great interest in many of the lad's schemes and plans that had to do with the affairs of the troop of Boy Scouts of Hickory Ridge.
"Say nothing more about it, Elmer; I'm always glad to see you"; and yet Elmer noticed to his surprise that the colonel did not offer him his hand as usual.
He asked them to be seated, and all the while his keen eyes seemed to be roving uneasily toward Mark; and several times Elmer saw him shake his head slightly.
For a few minutes they talked of various things. Elmer asked how the monkey was getting on, and the gentleman told them that Diablo had grown so vicious that he had been compelled to send him away to the Central Park collection of animals in New York City.
"I hated to part from the brute very much, too, but it seemed as though all the bad in his nature was coming to the surface, and he lost much of the charm he used to have for me." Then to the surprise of the boys the colonel leaned forward, adding: "Let me take your caps, boys."
"But we can only stay a short time, sir; I promised my mother to be home at eleven, because she wants me to go somewhere with her," Mark said, although he could not very well refuse to let the persistent gentleman take his cap.
Elmer stared when he saw the colonel actually examine the head gear of his chum. Nor was his astonishment at all lessened when he heard what he said.
"Oh, I will not detain you more than five or ten minutes at the most, I promise you, boys. By the way, I see that both of you have the habit of fastening your initials inside your caps. I suppose most boys do that because they are apt to get their head gear mixed when they wrestle and knock around; isn't that so, Mark?"
"Why, yes, sir, I guess that's the main reason they put the initials there," replied the one addressed, his eyes opening wide with surprise at the peculiar turn given to the conversation by the colonel.
"I suppose, now, you've always done it, Mark?" continued the gentleman, watching the boy's face.
"For several years, yes, sir. I've had as many as five sets of initials in that time. And the habit has saved me a lot of caps, too. If a fellow claims mine, all I have to do is to point at the three initials inside, and he gives up."
"H'm! like this, for instance," remarked the colonel, picking something up from behind a pile of books on his table and holding it out.
It was a fairly well-worn cap, and had evidently belonged to a boy. Elmer immediately sat up and began to take notice. He realized that the colonel must indeed have an object in asking Mark to drop in and see him.
For unless he was very much mistaken Elmer had seen that same cap before, many times, and on the head of his chum!
As for Mark, his eyes had opened very wide as they fastened on the article the gentleman was holding out before him.
"Will you kindly take this cap in your hands, my boy?" said the colonel, and almost mechanically Mark did so, for as yet he could not find his voice to express his mingled feelings.
"Please examine it, now, and tell me if you have ever seen it before," continued the colonel, whose heavy brows were lowered, as though under their shelter he were trying to analyze the emotions that chased each other across the face of the boy.
Mark made a pretense of looking inside and out, but it was not necessary, for the fellow who cannot instantly recognize a cap he has worn for some months must be pretty dense indeed.
"Well?" said the gentleman, with an interrogation point in the one word.
"I know it is mine, sir, because – well, every little mark about it is familiar, even to this little triangular tear. Besides, here are my initials inside – just as they are in this other cap I own – M. A. C., which stand for Mark Anthony Cummings."
The gentleman moved uneasily. It seemed as though he might be both surprised and annoyed because of this frank acceptance of the ownership of the cap.
"You're quite positive there can be no mistake – that some other boy may not have the same initials?" he asked.
"I don't know of a single one, do you, Elmer?" replied Mark, steadily.
"Not that I can recall just now; and besides, Mark, I ought to know that cap as well as you, and I'm ready to declare it's your property. I'm only wondering how it happens to be in the possession of Colonel Hitchins after you lost it," Elmer remarked, watching the face of the gentleman and wondering why he looked so downcast over such a little thing.
"I'm sorry to hear you say it belongs to you, Mark, because you are one of the last boys I'd dream of accusing of such a thing as robbery."
"Robbery!" gasped Mark, his face turning a trifle white with the shock.
"It is just that, for my premises were invaded last night by some bold thieves, who raided my choice peach trees, and almost cleaned them of the prize fruit that I would not have taken its weight in silver for. And I regret to say that this morning I found this self-same cap under those trees, where it would appear it had been accidentally dropped by one of the fruit thieves."
CHAPTER III.
WHEN THE CHALLENGE CAME
A silence so dense that, as Elmer afterward said, it could almost be felt gripped that library when the colonel made his astonishing declaration.
The two boys stared at each other in dismay. Then Mark once more looked down at the cap he held in his hand, as though he expected it to be given speech in order to indignantly deny the accusation. Twice he opened his mouth to say something, but no sound followed.
"Please remember, Mark, that I am not accusing you of having done this miserable thing," continued the gentleman in a softer tone; "I cannot find it in my heart to believe that you would be guilty of doing an old friend such an unkindness. But I found the cap just where I stated; it bore those initials, and I sent for you to see if you claimed it. And now, could you tell me how it chanced to come
