There is water in the desert this time of year and some feed, but it will be a hard, a terrible march. We shall lose a great deal of our stock, one in ten, perhaps; The Wolf thinks it may be as high as five in ten. We shall start tomorrow an hour before sunset, making a short march of about ten miles to a place where there is a spring along the trail the ancients used. It is strange to see all across the desert evidence of the great work they accomplished. After five hundred years the location of their well graded trail, with its wide, sweeping curves, is plainly discernible. It is a narrow trail, but there are signs of another, much wider, that we discover occasionally. It follows the general line of the other, crossing it and recrossing it, without any apparent reason, time and time again. It is almost obliterated by drifting sand, or washed away by the rains of ages. Only where it is of a material like stone has it endured. The pains those ancients took with things! The time and men and effort they expended! And for what? They have disappeared and their works with them. As we rode that first night Rain Cloud rode often at my side and, as usual, he was gazing at the stars. “There is so much that we do not know,” sighed Rain Cloud; “yet all that we can spare the time for is thoughts of fighting. I shall be glad when we have chased the last of the Kalkars into the sea, so that some of us may sit down in peace and think.” “It is handed down to us that the ancients prided themselves upon their knowledge, but what did it profit them? I think we are happier. They must have had to work all their lives to do the things they did and to know all the things they knew, yet they could eat no more, or sleep no more, or drink no more in a lifetime than can we. And now they are gone forever from the Earth and all their works with them and all their knowledge is lost.” “And presently we will be gone,” said Rain Cloud. “And we will have left as much as they to benefit those who follow,” I replied. “Perhaps you are right, Red Hawk,” said Rain Cloud; “yet I cannot help wanting to know more than I do know.”
