Dickenson sprang forward to his comrade's help, but stopped short as he realised that in that narrow space there was only room for a struggle between two, and by interfering he would be more likely to hinder his friend than help. Hence it was that he stood waiting for his opportunity, listening to the hoarse breathing of the wrestlers and watching the faintly seen struggle--for capture on the one part, for ridding himself of his adversary by pushing him off the shelf on the other. In a very few moments Lennox had recognised the fact that he was overmatched; but this only roused the stubborn bull-dog nature of the young Englishman, and setting his teeth hard, he brought to bear every feint and manoeuvre he had learnt at his old Devon school, where wrestling was popular, and in the struggles of the football field. But all in vain: his adversary was far too heavy for him, and, to his rage and discomfiture, in spite of all his efforts he found one great arm tightening about his ribs with crushing pressure, while the man was bending down to lift him from the shelf, evidently to hurl him off into space. The position was desperate, and in its brief moments Lennox did all that was in his power, tightening his grasp in the desperate resolve that if so savage a plan was carried out he would not go alone. It might have been supposed that in his emergency-he would have called to Dickenson for help, but the fact was that his adversary so filled his thoughts that there was no room for his comrade's presence, and he struggled on, straining every muscle and nerve. But, to repeat the previous assertion, he was completely overmatched by a desperate man; and, unless Dickenson could have interfered and saved him, Lennox's fate was to be thrown from the rocky ledge out into the black shadowy air, to fall heavily, crushed and broken, upon the stones below. But fate favoured him at the last pinch, for as his enemy by sheer weight and pressure bore him back and then lifted him from the shelf preparatory to hurling him outward, Lennox suddenly gave up resisting, loosening his grasp so as to take fast hold round his enemy's neck, when the sudden cessation of resistance had the effect of throwing the latter off his balance just when he was very near the edge where he intended to plant his foot down and check his farther progress. The result was that he put his foot down a few inches too far, his heel pressing down upon the rock where his toes should have been, and before he could recover himself his foot was down over the side, while by a frantic wrench Lennox flung himself sidewise inward.
