Crusoe crouched immediately, and his master made his observations of the drove, and the dispositions of the ground that might favour his approach, for they were not within rifle range. Having done so he crept slowly back until the undulation of the prairie hid him from view; then he sprang to his feet, and ran a considerable distance along the bottom until he gained the extreme end of a belt of low bushes, which would effectually conceal him while he approached to within a hundred yards or less of the troop. Here he made his arrangements. Throwing down his buffalo robe, he took the coil of line and cut off a piece of about three yards in length. On this he made a running noose. The longer line he also prepared with a running noose. These he threw in a coil over his arm. He also made a pair of hobbles, and placed them in the breast of his coat, and then, taking up his rifle, advanced cautiously through the bushes--Crusoe following close behind him. In a few minutes he was gazing in admiration at the mustangs, which were now within easy shot, and utterly ignorant of the presence of man, for Dick had taken care to approach in such a way that the wind did not carry the scent of him in their direction. And well might he admire them. The wild horse of these regions is not very large, but it is exceedingly powerful, with prominent eye, sharp nose, distended nostril, small feet, and a delicate leg. Their beautiful manes hung at great length down their arched necks, and their thick tails swept the ground. One magnificent fellow in particular attracted Dick's attention. He was of a rich dark-brown colour, with black mane and tail, and seemed to be the leader of the drove. Although not the nearest to him, he resolved to crease this horse. It is said that creasing generally destroys or damages the spirit of the horse, so Dick determined to try whether his powers of close shooting would not serve him on this occasion. Going down on one knee he aimed at the creature's neck, just a hair's-breadth above the spot where he had been told that hunters usually hit them, and fired. The effect upon the group was absolutely tremendous. With wild cries and snorting terror they tossed their proud heads in the air, uncertain for one moment in which direction to fly; then there was a rush as if a hurricane swept over the place, and they were gone.
