"It is estimated that there are all of a hundred thousand wild horses in the different ranges of this state," replied the guide.
"You haven"t told us yet what the invitation is," reminded Stacy.
"You haven"t given me a chance," laughed Tom. "Well, the invitation is to join in a wild horse hunt."
"Hooray!" shouted the lads.
"Very interesting," agreed the Professor.
"And lively, too," added the guide. "The boys took quite a fancy to you young gentlemen after the roping trick, and said if you would join in a hunt, you"d get all the fun that was coming to you."
Tad grinned at the recollection of their first meeting with the wild horse hunters.
"Whe--when do we join them?" asked Chunky enthusiastically.
"It will be a week or more yet before we reach that part of the desert where the hunts take place--that is, if we have good luck. But if we have any more such experiences as we have just pa.s.sed through we shall not get there this summer," laughed the guide.
By sunset, that day, the town of Eureka had disappeared behind the copper colored hills, and the Pony Rider Boys were again merely tiny specks on the great Nevada Desert.
They pitched the new white tents for the first time that night, having made camp earlier than usual because they were not accustomed to working with the new outfit. No one knew where to find anything, which furnished the lads with plenty of amus.e.m.e.nt.
Ned and Tom Parry cooked the supper over a sage brush fire. They had brought a few cans of milk with them, but after sampling it all hands declared their preference for the condensed brand of which they had purchased a liberal supply. The fresh milk procured in Eureka was strong with the sage brush taste, as was almost everything else in that barren country.
The ponies refused the sage brush for their evening meal, having had a supply of real fodder back in town, so they were staked out near a growth of sage that they might browse on during the night should they decide that they were hungry enough.
"Well, I wonder what will happen to-night," said Tad, as they finished the evening meal.
"Let us hope that it will be nothing more serious than pleasant dreams," smiled Professor Zepplin.
"That means you, Chunky," nodded Ned. "You are not to have the nightmare to-night, remember."
"And you look out for your tootsie-wootsies," retorted Chunky.
"We shall have to take a long ride to-morrow," announced the guide.
"Why to-morrow?" asked Ned.
"It is all of twenty miles to the next water hole, or where the next water hole should be. One cannot depend upon anything in this country."
"Haven"t we enough water with us?" asked the Professor.
"Enough to last us through to-morrow--that"s all. We shall have to get water at night; so, if we have no interruptions during the night, we shall make another early start."
"Stacy, see to it that you do not lose your trousers this time. We don"t wish to be disgraced by you again to-morrow," warned Ned.
Stacy merely grimaced, making no reply. He knew that he had not been the one to get the worst of it, and so did his companions. He was quite satisfied with the punishment that had been meted out to Ned Rector.
All hands turned in shortly after dark. They were tired after the long day"s ride in the broiling sun. Besides, they had not yet made up the sleep they lost two nights before when the "twister" invaded their camp and wrecked it.
The boys had been asleep only a short time, however, before the entire camp was startled by a long, thrilling wail.
All the Pony Riders were wide awake in an instant, listening for a repet.i.tion of the sound. It came a moment later.
"K-i-i-o-o-o-o! K-i-i-o-o-o-o! K-i-i-o-o-o-k-i!"
The boys leaped from their tents. The sound plainly come from some wild animal, but what, they did not know.
"Wha--what is it? A lion?" stammered Stacy.
"I--I don"t know," answered Walter. "Do you, Tad?"
"I certainly do not. It"s no lion, though. There are none here?"
"Maybe it"s a pack of wolves," suggested Ned. "There must be a lot of them to make such a howling as that."
"D-d-d-d-do you thi--thi--think they"re going to attack us?" stammered Stacy.
"How do we know?" snorted Ned.
Neither the Professor nor the guide having made their appearance, the boys took for granted that the two men were asleep. Such was the case so far as the Professor was concerned, but Tom Parry was lying on his bed awake, a quiet smile on his face.
"Are you sure it"s a wild animal, Tad?" whispered Walter.
"Of course. What else could it be?"
"Then I"ll tell you what let"s do."
"What?" demanded Ned.
"Let"s get our rifles and crawl up to the top of that knoll yonder, where the sound seems to come from----"
"And take a shot at them," finished Ned. "Good idea. What do you say, Tad?"
"I guess there will be no harm in it," decided the lad, considering the question for a minute.
They had moved away from the tents so that the sound of their voices should not arouse the sleeping men there.
"Two guns will be enough. We"re not so liable to hit each other if only two of us have them."
"Who is going to shoot?" demanded Walter.
"What"s the matter with Ned and Chunky?"
That suited all concerned.
"You"d better hurry. The animals have stopped howling," advised Tad.
Ned and Stacy ran lightly to their tents, returning quickly with their rifles. Stacy bore the handsome telescope rifle that he had won in a pony race during their exciting trip through the Ozark Mountains. Even in the moonlight one could see a long distance with the aid of the telescope on the gun"s barrel.
