That the rustlers were working under a well organized system was evident. That they were directed by a master of the game was ceaselessly beaten into the consciousness of the Association by the diversity, dash and success of their raids. No one, save the three men whom they had destroyed, had ever seen them. But, like Tamale Jose, they had raided once too often.

Mr. Trendley, more familiarly known to men as “Slippery,” was the possessor of a biased conscience, if any at all. Tall, gaunt and weather-beaten and with coal-black eyes set deep beneath hairless eyebrows, he was sinister and forbidding. Into his forty-five years of existence he had crowded a century of experience, and unsavory rumors about him existed in all parts of the great West. From Canada to Mexico and from Sacramento to Westport his name stood for brigandage. His operations had been conducted with such consummate cleverness that in all the accusations there was lacking proof.

Only once had he erred, and then in the spirit of pure deviltry and in the days of youthful folly, and his mistake was a written note. He was even thought by some to have been concerned in the Mountain Meadow Massacre; others thought him to have been the leader of the band of outlaws that had plundered along the Santa Fe Trail in the late ’60’s. In Montana and Wyoming he was held responsible for the outrages of the band that had descended from the Hole-in-the-Wall territory and for over a hundred miles carried murder and theft that shamed as being weak the most assiduous efforts of zealous Cheyennes. It was in this last raid that he had made the mistake and it was in this raid that Frenchy McAllister had lost his wife.

When Frenchy had first been approached by Buck as to his going in search of the rustlers he had asked to go alone. This had been denied by the foreman of the Bar-20 because the men whom he had selected to accompany the scout were of such caliber that their presence could not possibly form a hindrance. Besides being his most trusted friends they were regarded by him as being the two best exponents of “gun-play” that the West afforded. Each was a specialist: Hopalong, expert beyond belief with his Colt’s six-shooters, was only approached by Red, whose Winchester was renowned for its accuracy. The three made a perfect combination, as the rashness of the two younger men would be under the controlling influence of a man who could retain his coolness of mind under all circumstances.

When Buck and Frenchy looked into each other’s eyes there sprang into the mind of each the same name Slippery Trendley. Both had spent the greater part of a year in fruitless search for that person, the foreman of the Tin-Cup in vengeance for the murder of his wife, the blasting of his prospects and the loss of his herds; Buck, out of sympathy for his friend and also because they had been partners in the Double Y. Now that the years had passed and the long-sought-for opportunity was believed to be at hand, there was promised either a cessation of the outrages or that Buck would never again see his friends.

When the three mounted and came to him for final instructions Buck forced himself to be almost repellent in order to be capable of coherent speech. Hopalong glanced sharply at him and then understood, Red was all attention and eagerness and remarked nothing but the words.

“Have yu ever heard of Slippery Trendley?” Harshly inquired the foreman.

They nodded, and on the faces of the younger men a glint of hatred showed itself, but Frenchy wore his poker countenance.

Buck continued: “Th’ reason I asked yu was because I don’t want yu to think yore goin’ on no picnic. I ain’t shore it’s him, but I’ve had some hopeful information. Besides, he is th’ only man I knows of who’s capable of th’ plays that have been made. It’s hardly necessary for me to tell yu to sleep with one eye open and never to get away from yore guns. Now I’m goin’ to tell yu th’ hardest part: yu are goin’ to search th’ Staked Plain from one end to th’ other, an’ that’s what no white man’s ever done to my knowledge.

“Now, listen to this an’ don’t forget it. Twenty miles north from Last Stand Rock is a spring; ten miles south of that bend in Hell Arroyo is another. If yu gets lost within two days from th’ time yu enters th’ Plain, put yore left hand on a cactus sometime between sun-up an’ noon, move around until yu are over its shadow an’ then ride straight ahead that’s south. If you goes loco beyond Last Stand Rock, follow th’ shadows made before noon that’s th’ quickest way to th’ Pecos. Yu all knows what to do in a sand-storm, so I won’t bore you with that. Repeat all I’ve told yu,” he ordered and they complied.

“I’m tellin’ yu this,” continued the foreman, indicating the two auxiliaries, “because yu might get separated from Frenchy. Now I suggests that yu look around near the’ Devils Rocks: I’ve heard that there are several water holes among them, an’ besides, they might be turned into fair corrals. Mind yu, I know what I’ve said sounds damned idiotic for anybody that has had as much experience with th’ Staked Plain as I have, but I’ve had every other place searched for miles around. Th’ men of all th’ ranches have been scoutin’ an’ th’ Plain is th’ only place left. Them rustlers has got to be found if we have to dig to hell for them. They’ve taken th’ pot so many times that they reckons they owns it, an’ we’ve got to at least make a bluff at drawin’ cards. Mebby they’re at th’ bottom of th’ Pecos,” here he smiled faintly, “but wherever they are, we’ve got to find them. I want to holler ’Keno.”

“If you finds where they hangs out come away instanter,” here his face hardened and his eyes narrowed, “for it’ll take more than yu three to deal with them th’ way I’m a-hankerin’ for. Come right back to th’ Double Arrow, send me word by one of their punchers an’ get all the rest you can afore I gets there. It’ll take me a day to get th’ men together an’ to reach yu. I’m goin’ to use smoke signals to call th’ other ranches, so there won’t be no time lost. Carry all th’ water yu can pack when yu leaves th’ Double Arrow an’ don’t depend none on cactus juice. Yu better take a pack horse to carry it, an’ yore grub yu can shoot it if yu have to hit th’ trail real hard.”

The three riders felt of their accouterments, said “So long,” and cantered off for the pack horse and extra ammunition. Then they rode toward the Double Arrow, stopping at Cowan’s long enough to spend some money, and reached the Double Arrow at nightfall. Early the next morning they passed the last line-house and, with the profane well-wishes of its occupants ringing in their ears, passed onto one of Nature’s worst blunders the Staked Plain.
