With sudden yells, accompanied by as sudden a rush, a band of the Greasers now rode straight for Bud, Dick, Nort and some of the Diamond X outfit with our heroes. So fierce was the attack, and in such numbers, that there was nothing for our friends to do but retreat, for the time being at least. This attack took place in a part of the bowl where there were a large number of immense boulders scattered. Seeing that these formed a natural protection, or breastwork, Bud called to his cousins and the men to get behind the stones. "Make the horses lie down!" was his advice. "We'll fight Indian fashion!" And, at this point, at least, this became the style of the battle. The Greasers rode fast, endeavoring to cut off Bud and his party, but the latter reached the haven of rocks first, and with the horses on their sides, positions the steeds were glad enough to assume, doubtless, the advantage was on the side of the boy ranchers. They were protected by rocks, from behind which they could fire, while the enemy was in the open. But the enemy far outnumbered our friends, and the latter, for the time being, were in the position of persons besieged. For, no sooner had the Greasers seen what was the object of Bud and his followers, than the lawless ones took such small shelter as they could find, some behind their prostrate horses, and began firing at the boy ranchers' party. And as the renegade Mexicans were, in a number of cases, armed with rifles, the odds against Bud and his chums were increased. True, the Greasers were not good marksmen, but a rifle in the hands of even a poor shooter is often more than a match for a .45 revolver in the hands of an expert. "Pick 'em off!" cried Bud, as bullets zinged their way in among the rocks behind which he and his friends were hidden. "Pick 'em off, but don't expose yourself!" This was good advice if it could have been followed, but to fire effectively it was necessary for those of the Diamond X outfit to take aim over, or to one side, of the rocks, and when this was done, some part of the body was exposed. At such times the watching Greasers fired. It was now an actual state of siege as far as Bud and his immediate companions were concerned, and they were outnumbered. Several of Bud's party, including Nort this time, had been slightly wounded. But, in turn, they had wounded some Greasers, too, one vitally, as was learned later. Meanwhile, Snake and Kid were having their own troubles with the party of Greasers they had been sent off to intercept and prevent from driving off the cattle. More Mexicans had joined their comrades, and Kid and Snake were obliged to beat a retreat, joining Slim and his forces, who were fighting the main, and larger body of rustlers.
