"Ho, ho! ho, ho!" he exploded. "Hard luck when a fellow"s company is so thick that he has to laugh at his own jokes. Ho, ho, ho! Ha, ha, ha! It is to smile, but n.o.body smiles. You make me tired."
"As I have already observed, I think it is going to rain," said Tad.
"Must be getting warmer, then. A minute ago you said it was going to snow. It"s my private opinion that you don"t know what you think.
Ned doesn"t know any more. The professor is the only one in the outfit who has a sense of humor. _He_ knows when it"s time to laugh.
Ha, ha!"
Professor Zepplin was smiling broadly. Stacy"s joke was just dawning upon the professor. But Tad"s mind at that juncture was in another direction. The lad had raised his head in a listening att.i.tude, his glance fixed keenly on the other side of the camp ground.
"Did you see something?" whispered Walter.
Tad shook his head.
"You heard something?"
"Never mind. Go on with the fun. Get Chunky to tell you when it is time to laugh."
About this time Stacy got up, still chuckling to himself, and started for a cup of water.
"Time to laugh. Ha, ha! What! Ha, ha; ho, h---"
The fat boy paused abruptly. He was down on his knees about to dip up a cupful of water when chancing to raise his eyes he saw something that caused the word to die on his lips.
A man stood just on the other side of the stream, lounging against a tree, observing the fat boy with an amused smile.
"Oh, wow!" howled the fat boy, in such a tone of alarm that the rest of the outfit sprang up and ran toward him. "Wow! Look!"
At this juncture the stranger leaped the narrow stream and was standing beside Stacy facing toward the camp when the others came up.
"I suppose I should introduce myself before matters go any further,"
smiled the newcomer. "I know you, but you do not know me. You are the Pony Rider Boys. I am Captain Billy McKay of the Rangers."
Stacy uttered a shrill laugh, whereat the captain shot an inquiring glance at him.
"You---you are---are Captain McKay?" stammered Professor Zepplin.
"Yes. I had hoped to see you when you camped with Lieutenant Withem---"
"Yes, we were with "em," muttered Stacy. "And I guess we"ve got "em now."
"Unfortunately I was called away on that occasion. I promised myself that I should look you up at the first opportunity. I got on your trail this afternoon and as you were going in my direction I considered this an excellent opportunity to make your acquaintance. So here I am."
"But---but---" stammered the professor.
Tad was smiling, the others gazing at the newcomer blankly.
"Well, sir, what is it? One would think you had seen a ghost," laughed the captain.
"But, sir, you are the second man who has introduced himself to us as Captain McKay of the Ranger troop, to-day."
The captain"s blue eyes twinkled.
"Indeed! Then I must have a double. I should like to meet him."
"You look like the real thing," observed Stacy.
"Thank you. Then the other man did not?"
"He did not---to me," answered Tad Butler.
"How are we to know that you are the captain in person?" asked the professor suspiciously.
"I wear the badge and then here"s my open countenance," answered the Ranger with another hearty laugh.
"Professor, there can be no doubt that this is Captain McKay. I should know him now from the description given to me by Lieutenant Withem.
Won"t you join us? We have just about finished the grub, but there is more. I"ll cook something for you," proposed Tad.
"I"ll join you in a cup of coffee, thank you," replied Captain McKay.
"Lucky for him that Ned didn"t make the coffee for supper," muttered Stacy, but so low that the captain did not hear the remark.
Captain McKay, the real Captain McKay this time, was almost boyish in appearance. He was of about the same build as the other man who had declared himself to be the captain, but the real captain had light hair and laughing blue eyes, as opposed to the dark hair and eyes of the other man. The captain"s skin was fair. It seemed not to have suffered from exposure to the sun and storm of the plains.
Tad led the way to the camp, followed by the visitor and the rest of the Pony Rider outfit.
"Most remarkable, most remarkable," muttered the professor, taking keen sidelong glances at Captain McKay.
"You are Butler, aren"t you?" called the captain.
"Yes, sir," answered Tad, glancing back.
"I knew you the instant I set eyes on you. You"re a sharp young man.
You discovered me before I got into your camp."
"Discovered you?" exclaimed the professor.
"Yes. He heard me. I stepped on a stick that bent down under my foot.
The stick didn"t snap and how that young scout ever caught the faint sound is more than I can explain."
"So, that was what you were looking at?" laughed Ned.
"Tad"s got ears in the back of his head," added Stacy.
"I observe that all of you have pretty keen senses," smiled the Ranger captain. "Something smells good."
"It"s the coffee that Tad"s making for you," answered the fat boy solemnly. "How"s the going?"
"Pretty fair. How is it with you?" returned the captain.
