By this time the wounded limb had become terribly swollen, and Grosvenor complained of severe pain about the injured region. This, of course, was not to be wondered at, considering the rather heroic treatment to which the leg had been subjected, and Dick was not very greatly concerned about it. But what caused him to look very grave was the fact that his patient also complained of feeling cold, and manifested symptoms of approaching delirium, while his whole body was now beginning to be convulsed, at rapidly shortening intervals, by spasms of violent and uncontrollable twitching. Without wasting a moment Dick now had recourse to alcohol, freely dosing his patient with neat brandy, in the hope of inducing a condition of intoxication--for he knew that if he could succeed in this the excess of alcohol in the system would neutralise the venom, and his patient would be saved. But it was not until he had administered nearly a quart of the spirit that the desired symptoms began to appear; and it was long past midnight before the twitching convulsions entirely ceased and the patient sank into a deathlike sleep; by this time also the swelling of the limb was perceptibly subsiding; and when at length Dick turned down the lamp and disposed himself to take such rest as he might be able to snatch in a folding chair by the side of his friend's hammock, he had the satisfaction of knowing that the crisis was past and Phil would live. Up to this moment the young doctor had been far too busy and altogether too deeply preoccupied in attending upon his patient to give any attention to, or indeed be more than vaguely aware of, what was happening outside the tent, although there certainly had been moments when sounds of a more than usually alarming character had reached his ears so distinctly and obtrusively as partially to distract his attention for the fraction of a second or so; but now that Grosvenor was asleep and safe, and Dick began to feel that he also would be the better for a little rest, outside sounds began to obtrude themselves upon him with a force and persistency that would not be denied, and he awoke to a consciousness of the fact that something quite out of his ordinary experience was happening.
