We questioned the driver about the lake, and whether there were any patos (ducks); but he only shrugged his shoulders and said: “Quien sabe?

Suddenly we saw the shimmer of placid water ahead, and soon drew up at a board shack some little distance from the lake. Our man had told us to take nothing but our guns and ammunition, as his caretaker, who lived in the hut we had just reached, would provide everything else. We took a tent and a few provisions anyway, just to be safe, and it was lucky that we did. Not only had nothing been provided, but the tenant had not even been advised of our coming. He had only one dirty little room, but this he very generously placed at our disposal; however, we preferred to camp outside, although it was bitter cold. His wife consented to do the cooking.

The tent was hastily put up; then we hurried to the lake, leaving the family busily engaged in slaughtering a goat for lunch.

All the surrounding country is a wind-swept desert, there being no trees and but a few thorny bushes. In spots the sand and alkali dust is several feet deep. It seemed impossible that there could be a lake in such a parched-looking locality; but there lay the glistening sheet of water, stretching away into the distance as far as the eye could see. Along the edges were vast, shallow marshes, covering hundreds of acres; in these, sedges grew abundantly, forming shelter and providing a limitless feeding-ground for water-fowl. Half a mile from the bank stood great clumps of totoras, or cattails, rearing their tough, slender stems to a height of seven or eight feet above the water. What was infinitely more interesting to us, the whole surface of the lake, from its marshy edge to the rows of totoras fading away in the distance, was teeming with water-birds.

There were no boats to be had in the neighborhood, as the natives use reed rafts. They cut quantities of cattails, bind them into long, thick bundles and, lashing several of them together, form a craft that will support a man, although his feet are always under the icy water. Shooting from such a contrivance, unless it is larger than any I have seen, would be impossible. Therefore we started to walk along the muddy banks in the hope that something would fly over.

After having gone a short distance, a commotion among the sedges attracted our attention, and a moment later a large gray fox appeared and trotted away. A charge of No. 4 shot stopped him; he was in splendid fur and made a desirable addition to our lot of trophies. Later, we saw them frequently; they haunt the edges of the marsh and feed upon coots and wounded ducks. Carrion-hawks, also, were always about in considerable numbers and reaped a rich harvest.

Coots of several species were running around everywhere. They wandered far away from the water, apparently to pick up toads or lizards, and as we approached, scurried back to the marsh or hid in the dense, low bushes, where they remained motionless until the cause of their fright had passed. Ducks were all well out of range and refused to fly over. I hesitate to estimate their numbers, there were such countless thousands, but in many places the water was covered with them, and there were large white geese and black-necked swans. Black rails of good size darted about or waded boldly out in the open, jerking their tails and clucking.

It did not take us long to discover that we were too late in the day for ducks, so we started back to camp, cutting across the country. Several tinamous got up singly, with a loud whir of wings; they flew straight and fast, a great contrast to the slow, wavering flight of the forest-inhabiting species.

When we reached camp, some of the goat-meat had been roasted and we had a feast! The rest of the day was spent in straightening up camp.

Our eight by twelve foot “balloon silk” tent had been put up under a shed adjoining the house; this protected it from the wind on at least one side. To be of any use in the tropics, the tent must of course be provided with a ground-cloth and bobbinet curtains; it should also contain a window, screened with netting, in the roof. We did not need the curtains, so tied them back. A brazier was kindled, and after it was filled with glowing embers, it was taken into the tent; it warmed the tent thoroughly within a few moments and kept a fire all night. The window, which was always kept open, served its mission splendidly as a means of ventilation.
