Under any other circumstances, the idea of passing that barrier could not, of course, be entertained. But there was one thing in Phil’s situation which made him think that the deed might be done; that it was not impossible, or even difficult. This one thing that gave hope was the river. Its stream might still bear him on its bosom, amidst those fires; he might find protection in its running waters. He could keep cool amid that fervent heat; and as the stream would itself bear him on, he would not need to make any efforts except those which served to guide him in a right course. As he thought of this, and of the possibility of making his passage, he felt eager to go, but was restrained by other thoughts. How far might those fires extend? How long could he endure the presence of those flaming woods, even in the waters of the river? Could he breathe? Would not the intense heat make breathing impossible? That burning district might extend for many and many a mile; and if he once ventured there, how would he ever get out of it? Or again, might not that possible obstacle in the river waters, which he had dreaded, be found down there amid the burning forests? And if so, what a terrible fate would be his!--to be arrested amid raging fires by a cataract--unable to advance, unable to retreat, unable to go ashore! If he could only form some idea as to the possible extent of the fire,--if he could only see beyond that next turn in the river, and find out how far those fiery shores ran on,--then he might know whether there was any hope. But this was impossible. The land before his eyes was a land of fire; its trees blackened by the fire, or still glowing red as they quivered under its attack; and there was no way by which he might know anything more than this. At last there came a thought which gave him great encouragement. He thought that the fire in its march must exhaust itself after a certain time, and that after the trees were actually consumed there must be a departure of the heat. It was in the advanced part of its march that it maintained this furnace glow; at a certain distance behind, the heat might not be intolerable. If, therefore, he could traverse the flames and the fire that he saw before him, he might find the country beyond not much worse than it was here. This thought, this hope, decided him. He determined to stake everything upon this, and venture upon that fiery path. But before he attempted it he made the only preparation possible. What he dreaded most was the scorching glow of those flames; and as he did not know to what extent they might affect him, he wished above all things to guard his head against that danger.
