the hill which the boys proposed to pass around was about a quarter of a mile in length and but slightly less in breadth—much greater than either of them suspected when they set out. it rose like a peak to the height of several hundred feet, as if it were an offshoot from the main ridge of hills, left to flourish by itself.

howard walked slowly along, after glancing back at his cousin until the intervening wood concealed him from view, when he gave a short, sharp whistle, which was immediately answered. then, appreciating the necessity of haste, he quickened his footsteps.

as he advanced the hills assumed proportions of which he had not dreamed, and that raised in his mind strong doubts as to the wisdom of separating from his companion. he would not have done it had not the latter urged him so. misgivings now arose in the mind of the boy. he looked upon his duty as that of restraining and tempering elwood's impulsiveness. he had done so several times to his manifest advantage; but on this day, as howard looked back, it really appeared as if he had bidden good-by to his senses. their separation from tim was almost criminal in its foolishness, and yet he had scarcely raised an objection; and now, was not the last proceeding still more imprudent? as it stood, the three members of the little party who should never have been out of each other's sight, were now a good distance from each other, and that, too, when in a hostile country.

from these rather sad reflections howard was roused by the faint, echoing whistle of elwood.

"he is all right," thought he, feeling much relieved, as he placed his fingers to his mouth and returned the whistle. "we are both now passing around the hill, so that we cannot get further apart, and can keep within call all the time."

admonished by the lateness of the hour, howard almost ran. he grew somewhat impatient at the unexpected extent of the hill; but finally he passed beyond the southern point, and as he stood and listened, he heard the murmur of the river—proof that it was close at hand.

"now," thought he, "if elwood will only hurry, we have a good chance of finding tim before he gives us up for lost."

the boy could not see that anything at all was gained by their course in passing around the ridge. neither of them, were in sight of the river, and would have to advance still further before they could form any idea of their whereabouts. he was resolved to do this in company with his cousin, so that precisely the same thing would have been accomplished had they remained together.

howard having hurried a great deal, thought it likely that he was some distance in advance of his cousin. he stood some minutes listening for his signals, and then began walking toward the northern end of the hill that he might meet him as he came around. he observed as he advanced that they increased in rocky ruggedness, and could see that it was quite a feat to pass through them.

going some distance he paused again, and listened intently, but nothing beside the deep murmur of the woods reached his ear.

"what can it mean?" he finally asked himself, as a vague alarm crept over him. "we must be much closer together than we were before, and i haven't heard him whistle for the last half-hour."

he began to doubt whether it was best to proceed further or not. it might serve only to mislead in case elwood was searching for him. still hearing nothing to indicate the location of his friend, he made the signal himself—a long, screeching whistle, that rang out in the solemn stillness with a penetrating clearness that sent the chills over him from head to foot.

"he must hear that if he is within a mile," was his reflection, as he leaned his head forward and listened for the first approach of the answering sound.

ten, fifteen, twenty minutes passed away, but nothing was heard, and the poor boy looked around in sore alarm.

"can it be that elwood is jesting?" he asked himself. "he would not do so if he knew what i am suffering."

howard was now in great distress. he could not decide what to do. if he advanced he could feel no assurance of meeting his friend, while a retreat was equally hopeless.

where was elwood? had he wandered off among the hills, tempted by the wild scenery, and had he lost his way? was he searching for his cousin? or had he been found by indians?

the last inquiry had been rising in howard's mind for a half-hour, but he had resolutely forced it down again, until he could keep it away no longer. he could find no other reason to account for the silence, and failure to answer his call. the whistle which he had given must have spread miles in every direction—so far that elwood could not have got beyond its range had the course of both been precisely opposite. no; it must——

but, hark! a faint, tremulous whistle comes to his ear. it is far away and sounds among the hills behind, as though it had labored up from some cave or chasm miles distant. howard held his breath, and as he anticipated, it came again so faintly and distantly that had he been walking he could not have heard it.

on both occasions it sounded behind him among the hills, though its tremulous faintness made it appear as though it came from far up in the air, or down deep in some of the gorges of the hills—so uncertain was the exact point of its starting.

poor howard was now in a dilemma. whether to attempt to follow up the signal or to go on to the river and search out tim o'rooney and the newfoundland was a question which was difficult to decide. but his eagerness to find his cousin led him on into the hills, until he had penetrated quite a distance. he then paused and listened for the signal, but none was ever to come to his ears again.

howard repeated the whistle over and over, and finally fired his gun; but both were equally fruitless. he waited where he was until dark, when with a sad heart he withdrew and resumed his tramp toward the river. gloomy indeed were his meditations, as he reflected on the occurrences of the day, and there was scarcely anything he would not do, if by any means he could recall his part since he landed upon the main shore.

in the course of half an hour he reached the river, and looked intently out into the semi-darkness to see whether he could recognize anything familiar; but so far as he was able to see, all was strange, from which he concluded that he had struck at a point lower down than where tim had been left.

he therefore began making his way south, that is, toward the source of the river, after halting and listening for some sound that might tell something either of tim or elwood. suddenly a threatening growl startled him, and then came the welcome bark of terror, and the next moment the dog was frolicking around him and showing his delight in the most extravagant manner.
