I see many instances of what might be called degenerates, misshapen heads, ill-shaped and deformed bodies, signs of a race too much inbred. They wear white cotton clothes, peaked straw hats and rawhide sandals. The men generally carry blankets (_zerapes_) folded across the shoulder which they wrap up in, as do their brothers on the highlands, when the air grows cold.

The coldness of the nights and the burning heat of the day are strange. I slept last night in flannel underwear, a woolen jersey over that and flannel pajamas still outside; then two thick wool blankets and a rubber _poncho_ over all. Early, toward one or two o’clock I woke up chilled to the bone. I put on my corduroy coat. I was just warm, for an icy wind was blowing down from the lofty altitudes of the _Tierra Fria_. This morning when the sun rose about six o’clock, the air was still cold. In an hour it was pleasantly warm, birds were singing and flying from tree to tree. By nine o’clock the sun blazed like a ball of fire. I am now, at half past nine, going about in slippers, in linen trousers and my thin pajama coat, and even then I hide from the sun. By ten o’clock a silence lies upon the land profound and overwhelming, not a living thing is astir, except only the lizards and the cicadas. The daylight ends precipitately. The day lasts only as long as the sun is up. By half past five the sun hangs above the mountains on the west. Suddenly it is gone. In fifteen minutes it is dark, the stars are out, and such white stars they are! The cold air of the highlands then settles down upon us for the night.
CHURUMUCO, MINA EL PUERTO, ON THE RIO DE LAS BALSAS, _December 6th_.
We were up before the day, our horses and mules having been fed with grain a little after midnight. Thus the food is digested before the journey of the day is begun. It was dazzling starlight with a gleaming streak of white moon. Our two pack beasts had been loaded, we had breakfasted and were in the saddles a little after four. A keen wind which cut like a knife-edge blew steadily down from the highlands behind us. I had kept on my warm clothes of the night. We traveled rapidly by the brilliant starlight and passing down the _aroyo_ along which we camped, turned down the San Pedro River toward the south. We crossed the stream frequently, traveling in single file. By seven o’clock the sun was peering over the hills and I began to shed my clothes. By half past eight I retained only my thinnest underwear, my pajama coat, my linen trousers and slippers. By ten o’clock the sun was scorching, our great Mexican _sombreros_ alone saving us from its fierce rays. Our way lay for twenty miles almost due south down the valley of the San Pedro, then turning to our left, we followed a slightly-traveled trail, crossing a succession of low hills, until after four long hours we came to immense plains or _llanos_ stretching flat as a table for twenty miles toward the Balsas River. The streams were dry, the leaves were falling from shrubs and trees. It was the dry season. Mesquit and cactus and mimosa were the only vegetation, except the blistered stalks of the sun-dried grasses. No water was visible anywhere. The ground was parched and cracked. A light breeze which followed us all day and a few highflying clouds, which now and then hid the sun, alone saved us from being almost broiled alive. The watch in my pocket became burning hot, I could scarcely hold it in my hand; the metal buttons on my clothes almost burned themselves loose; only the dryness of the atmosphere made it possible to have made this journey during the day.
