Had Escombe been ten years older than he actually was he would probably not have hesitated—while disclaiming anything in the nature of cowardice—to express very strongly the opinion that where there were two methods of executing a certain task, one of them perfectly safe, and the other seriously imperilling a human life, it was the imperative duty of the person with whom the decision rested to select the safer method of the two, particularly when that method offered equally satisfactory results with the other. But, being merely a lad, and as yet scarcely certain of himself, remembering also that his future prospects were absolutely at Butler’s mercy, to make or mar as he pleased, Harry contented himself with a disclaimer of any such feeling as fear, and expressed his readiness to perform the task in any manner which Butler might choose to approve. At the same time he confessed his inability to understand precisely how the required measurements were to be taken, and requested instructions.
“Why,” explained Butler impatiently, “the thing is surely simple enough for a baby to understand. You will be lowered over the cliff edge and let down the cliff face exactly five feet at a time. As it happens to be absolutely calm, the rope by which you are to be lowered will hang accurately plumb; all that you will have to do, therefore, will be to measure the distance from your rope to the face of the rock, at every five feet of drop, and you will then have the particulars necessary to plot a contour of the cliff face, from top to bottom. You will do this on both sides of the quebrada, and then measure the width across at the top, which will enable us to produce a perfectly correct section of the gorge.”
“But how am I to measure the distance from the rope to the cliff face?” demanded Harry. “For, as you will have observed, sir, the rock overhangs at the top, and the gorge widens considerably as it descends.”
“You can do your measuring with a ranging-rod,” answered Butler tersely; “and if one is not long enough, tie two together.”
“Even so,” persisted Harry, “I fear I shall not be able to manage—”
“Will you, or will you not, do as you are told?” snapped Butler. “If you cannot manage with two rods, I will devise some other plan.”
“Very well, sir,” said Harry. “If you are quite determined to send me over the cliff, I am ready to go. What rope is it your pleasure that I shall use?”
“Take the tent ropes,” ordered Butler. “You will have an ample quantity if you join them all together. Make a seat for yourself in the end, and then mark off the rest of the rope into five-foot lengths, so that we may know exactly how much to pay out between the measurements. Then lash two ranging-rods together, and you will find that you will manage splendidly.”
Harry had his doubts, for to his own mind the tent ropes seemed none too strong for such a purpose. Moreover, the clips upon them would render the paying out over the cliff edge exceedingly awkward; still, since it seemed that the choice lay between risking his life and ruining his professional prospects, he chose the former, and set about making his preparations for what he could not help regarding as a distinctly hazardous experiment. These did not occupy him very long, and in about twenty minutes he was standing at the cliff edge, with a padded bight of the rope about his body, and the two joined ranging-rods in his hand, quite ready to be lowered down the face. Then two peons whom he had specially selected for the task, drew in the slack of the rope, passed a complete turn of it round an iron bar driven deep into a rock crevice, and waited for the command of a third who now laid himself prone on the ground, with his head projecting over the edge of the cliff, to watch and regulate the descent. Then Harry, fully realising, perhaps for the first time, the perilous nature of the enterprise, laid himself down and carefully lowered himself over the rocky edge.
“Lower gently, brothers!” ordered the man who was supervising the operation, and the rope was carefully eased away until the first five-foot mark reached the cliff edge, while Butler, who now also began at last to recognise and appreciate the ghastly peril to which his obstinacy had consigned a fellow creature, moved off to a point about a hundred yards distant, from which he could watch the entire descent. And he no sooner reached it than he perceived that Harry’s objections to the plan were well grounded, and that, even with the two joined rods, it would be impossible for the lad to take the required measurements over more than the first quarter of the depth. This being the case, it was obviously his duty at once to put a stop to so dangerous an attempt, especially as he knew perfectly well that it was as unnecessary as it was dangerous; but to do this would have been tantamount to confessing that he had made a mistake, and this his nature was too mean and petty to permit, so he simply sat down and watched in an ever-growing fever of anxiety lest anything untoward should happen for which he could be blamed.
