A short ride brought the little cavalcade to the borders of the desert. Here, by common consent, a halt was made, to draw breath, as it were, before taking the final plunge into the fiery furnace.
“Before we go farther,” said General Trednoke, approaching Freeman, as he was tightening his girths, “I must tell you what is the object of this expedition.”
“It is not necessary, general,” replied the young man, straightening himself and looking the other in the face; “for from this point our paths lie apart.”
“Why so?” demanded the general, in surprise.
“What’s that?” exclaimed Meschines, coming up, and adjusting his spectacles.
“I’m not at liberty, at present, to explain,” Freeman answered. “All I can say is that I don’t feel justified in assisting you in your affair, and I am not able to confide my own to you. I wish you to put the least uncharitable construction you can on my conduct. To-morrow, if we all live, I may say more; now, the most I can tell you is that I am not entirely a free agent. Meantime--Hasta luego.”
Against this unexpected resolve the general cordially protested and the professor scoffed and contended; but Freeman stayed firm. He had with him provisions enough to last him three days, and a supply of water; and in a small case he carried a compact assortment of instruments for scientific observation. “Take your departure in whatever direction you like,” said he, “and I will take mine at an angle of not less than fifteen degrees from it. If I am not back in three days, you may conclude something has happened.”
It was certainly very hot. Freeman had been accustomed to torrid suns in the Isthmus; but this was a sun indefinitely multiplied by reflections from the dusty surface underfoot. Nor was it the fine, ethereal fire of the Sahara: the atmosphere was dead and heavy; for the rider was already far below the level of the Pacific, whose cool blue waves rolled and rippled many leagues to the westward, as, aeons ago, they had rolled and rippled here. There was not a breath of air. Freeman could hear his heart beat, and the veins in his temples and wrists throbbed. The sweat rose on the surface of his body, but without cooling it. The pony which he bestrode, a bony and sinewy beast of the toughest description, trod onwards doggedly, but with little animation. Freeman had no desire to push him. Were the little animal to overdo itself, nothing in the future could be more certain than that his master would never see the Trednoke ranch again. It seemed unusually hot, even for that region.
