The creature was pacing to and fro, like a well-trained sentry, its "round" being the curved crest of the sand-ridge, from which it did not deviate to the licence of an inch. Backward and forward did it traverse the saddle in a longitudinal direction--now poised upon the pommel, now sinking downward into the seat, and then rising to the level of the group, now turning in the opposite direction, and retracing in long uncouth strides the path over which it appeared to have been passing since the earliest hour of its existence! Independent of the surprise which the presence of this animal had created, there was something in its aspect calculated to cause terror. Perhaps, had the mids known what kind of creature it was, or been in any way apprised of its real character, they would have paid less regard to its presence. Certainly not so much as they did: for instead of advancing upon it, and making their way over the crest of the ridge, they stopped in their track, and held a whispered consultation as to what they should do. It is not to be denied that the barrier before them presented a formidable appearance. A brute, it appeared as big as a bull, for magnified by the moonlight, and perhaps a little by the fears of those who looked upon it, the quadruped was quite quadrupled in size. Disputing their passage too; for its movements made it manifest that such was its design. Backwards and forwards, up and down that curving crest did it glide, with a nervous quickness that hindered any hope of being able to rush past it, either before or behind, its own crest all the while erected, like that of the dragon subdued by Saint George. With all his English pluck, even stimulated by this resemblance to the national knight, Harry Blount felt shy to approach that creature that challenged the passage of himself and his companions. Had there been no danger _en arriere_, perhaps our adventurers would have turned back into the valley, and left the ugly quadruped master of the pass. As it was, a different resolve was arrived at, necessity being the dictator. The three midshipmen, drawing their dirks, advanced, in line of battle, up the slope. The devil himself could scarce withstand such an assault. England, Scotland, Ireland, abreast, _tres juncti in uno_, united in thought, aim and action, was there aught upon earth, biped, quadruped, or _mille-pied_, that must not yield to the charge? If there was, it was not that animal oscillating along the saddle of sand, progressing from pommel to cantel, like the pendulum of a clock. Whether natural or supernatural, long before our adventurers got near enough to decide, the creature, to use a phrase of very modern mention, "skedaddled", leaving them free, so far as it was concerned, to continue their retreat unmolested.
