The Boy Ranchers: or, Solving the Mystery at Diamond X

"Greasers and some Indians!" cried Slim, as he swept on along the trail. "Come on, boys!" he yelled and instantly his gun was in action, as was that of Babe Milton.

"Oh, why didn't I bring mine?" mourned Bud.

"Tough luck!" exclaimed Nort.

The advent of the rescue party had an instant effect. No sooner had Slim and Babe begun firing than there was silence on the part of the attackers. A few scattering shots were fired, one or two more wild yells smote the air and then there was more silence.

"That settles 'em," grimly observed Slim, as he began to reload his weapon, an example followed by Babe. At the same time those in the little camp, who had had their backs turned toward the rescue party, swung about with evident signs of relief on their faces.

A tall, slim man, with prematurely gray hair, stepped forward, resting the butt of his rifle on the ground as he surveyed the newcomers. Then his eyes sought those of Professor Blair.

"I see that you found help," he remarked quietly. "And just in time, too. They were about to rush us, I fear."

"I'm glad we came in time," the other scientist remarked. "I don't know your names, gentlemen," he went on, turning to Bud and the others, "but this is my chief, Professor Hendryx Wright."

"I shall take some other occasion to thank you," spoke Professor

Wright, with a smile that included all the rescuers from Slim to Dick.

"But just now one of my men, possibly two, need attention from a doctor. They have been shot."

"Better let me have a look at 'em," suggested Slim. "I'm not a doctor, but that brand isn't plenty out here. If they're too bad, we can take your men to the ranch. Where are they?"

Professor Wright waved his hand toward one of the tents, and while Slim dismounted to make his way there, Bud and his cousins had time to look about them.

In addition to four white men, which included the two professors, and two who were apparently assistants, there were several Mexicans or half-breeds. These were all armed and had, in common with their white employers, been firing at the attacking party. Of the latter no glimpse had been had. They seemed to have vanished into the forest with the approach of the rescuers.

"Do you have things like this happen every day, Bud?" asked Nort, with sparkling eyes, as the foreman disappeared into the tent where the wounded men lay.

"No, indeed. This is as much a surprise to me as it is to you fellows.

I didn't even know this camp was here."

"What do you reckon it is?" asked Dick.

"Give it up," answered Bud. "I reckon even Zip Foster couldn't make anything of this."

"Who's Zip Foster?" asked Nort.

"That's what a lot of us would give a deal to know, son," chuckled Babe, who was rapidly making a survey of the camp. "He's a secret friend of Bud's, an' – "

"Oh, cut it out!" exclaimed Bud, and even his tan did not altogether hide the blood that surged into his face.

While the two professors were conversing together in low tones, and their helpers, including two white men (evidently the Ed Newton and Silas Thorp spoken of by Professor Blair) were putting to rights the somewhat disrupted camp, Slim, the foreman, came from the tent.

"They're not much hurt," he declared. "Only flesh wounds, but they ought to be treated with some dope I've got at the ranch house. They can ride over, and I'll fix 'em up as best I can," he offered.

"You are very kind," murmured Professor Wright. "But it might be dangerous for them to do so."

"Dangerous!" exclaimed Slim.

"Yes, I mean it might inflame their wounds."

"Oh! Yes, it might," agreed the foreman after a moment of thought. "Wa'al, I can send one of the boys back for the medicine. Here they come now," he added, as, with whoops of delight at the prospect of a fight, a troop of other cowboys from the Diamond X ranch rode up. As Bud had surmised, his mother had sent them after the advance party.

"What's the row?" cried "Yellin' Kid" Watson, as he unlimbered his gun. It needed but one utterance of his to establish his nickname. He shouted almost every word he used.

"All over," said Slim, succinctly. "Don't know just what it's about, but it's all over."

The newcomers rode their horses into the camp, and Yellin' Kid, whose animal was a bit restive, nearly brought down one of the small tents. As it swayed, a flap opening because of the breaking of one of the ropes, Professor Wright sprang forward with a sharp cry.

"Don't go in there! No one must enter that tent!" sharply commanded the scientist.

"I wasn't aimin' to," remarked Yellin' Kid somewhat tartly and in rather grieved tones. "Come out of that, you soap footer!" he cried to his steed. "What do you mean, slippin' all over creation?"

He backed his animal away, but Professor Wright, summoning to his side Professor Blair, quickly fastened the tent shut again, paying no heed during this operation, to the cowboys.

"Seems mighty much afraid we'll see something we hadn't a right to," commented Bud to his cousins.

"Yes, he does act queer," agreed Dick.

"Suspicious, I call it!" whispered Nort. He was impulsive, and much more prone, than was his brother, to ascribe motives to others. "Maybe, after all, they have gold in there!" he said.

CHAPTER V

HITTING THE TRAIL

Bud Merkel shook his head as Nort Shannon offered this possible explanation of the action of Professor Wright.

"Never's been any gold found in these regions all the years I've lived here," he said.

"There's always a first time," countered Nort, while the cowboys gazed about them, talking in low voices.

"It must be something else," said Bud. "This is a prospecting bunch, it's easy to see that, but they're not after gold. These two professors are from some eastern college, I take it," he went on. "They may be after specimens of plants, or stones. Using their vacation this way. I've heard of it being done."

"That's right!" chimed in Dick. "Two of the professors from our Academy spent all one summer in the Adirondacks, getting material for a new geology book they were writing. Maybe that's what these professors are doing," he suggested.

"Then why are they keeping so blamed secret about it for?" asked Nort, impulsively. "There's no crime in getting rock specimens, or in making up a new geology, only I wouldn't want to do it," he finished with a grin. "I get enough of study all winter. We came out here to have fun!"

"And we've started in right!" declared his brother. "Fun and excitement."

"I reckon we'll have to let these fellows have their way," murmured Bud. "They aren't on our ranch, and this is a free country. They may have permission from the Double Z people to look for specimens here."

"Is this Double Z land?" asked Dick.

"Right about here is," answered Bud. "Our line runs over there, and back where we came from," and he motioned toward the ranch buildings. "Better be hitting the home trail too, soon," he commented. "It'll be dark in no time, and I'm as hungry as they make 'em!"

"You said something then!" declared Babe. "I don't see that we can do anything more here – they don't appear to want us overly much," he added.
