the weather was hot. In the patio of the comfortable little hotel we heard the cicadas; but I did not hear the extraordinary screaming whistle of the locomotive cicada, which I had heard in the gardens of the house in which I stayed at Asuncion. This was as remarkable a sound as any animal sound to which I have listened, except only the batrachian-like wailing of the tree hyrax in East Africa; and like the East African mammal this South American insect has a voice, or rather utters a sound which, so far as it resembles any other animal sound, at the beginning remotely suggests batrachian affinities. The locomotive-whistle part of the utterance, however, resembles nothing so much as a small steam siren; when first heard it seems impossible that it can be produced by an insect.
On December 17 Colonel Rondon and several members of our party started on a shallow river steamer for the ranch of Senhor de Barros, "Las Palmeiras," on the Rio Taquary. We went down the Paraguay for a few miles, and then up the Taquary. It was a beautiful trip. The shallow river—we were aground several times—wound through a vast, marshy plain, with occasional spots of higher land on which trees grew. There were many water-birds. Darters swarmed. But the conspicuous and attractive bird was the stately jabiru stork. Flocks of these storks whitened the marshes and lined the river banks. They were not shy, for such big birds; before flying they had to run a few paces and then launch themselves on the air. Once, at noon, a couple soared round overhead in wide rings, rising higher and higher. On another occasion, late in the day, a flock passed by, gleaming white with black points in the long afternoon lights, and with them were spoonbills, showing rosy amid their snowy companions. Caymans, always called jacares, swarmed; and we killed scores of the noxious creatures. They were singularly indifferent to our approach and to the sound of the shots. Sometimes they ran into the water erect on their legs, looking like miniatures of the monsters of the prime. One showed by its behavior how little an ordinary shot pains or affects these dull-nerved, cold- blooded creatures. As it lay on a sand-bank, it was hit with a long 22 bullet. It slid into the water but found itself in the midst of a school of fish. It at once forgot everything except its greedy appetite, and began catching the fish. It seized fish after fish, holding its head above water as soon as its jaws had closed on a fish; and a second bullet killed it. Some of the crocodiles when shot performed most extraordinary antics. Our weapons, by the way, were good, except Miller's shotgun. The outfit furnished by the American Museum was excellent—except in guns and cartridges; this gun was so bad that Miller had to use Fiala's gun or else my Fox 12-bore.
In the late afternoon we secured a more interesting creature than the jacares. Kermit had charge of two hounds which we owed to the courtesy of one of our Argentine friends. They were biggish, nondescript animals, obviously good fighters, and they speedily developed the utmost affection for all the members of the expedition, but especially for Kermit, who took care of them. One we named "Shenzi," the name given the wild bush natives by the Swahili, the semi-civilized African porters. He was good-natured, rough, and stupid—hence his name. The other was called by a native name, "Trigueiro." The chance now came to try them. We were steaming between long stretches of coarse grass, about three feet high, when we spied from the deck a black object, very conspicuous against the vivid green. It was a giant ant-eater, or tamandua bandeira, one of the most extraordinary creatures of the latter-day world. It is about the size of a rather small black bear. It has a very long, narrow, toothless snout, with a tongue it can project a couple of feet; it is covered with coarse, black hair, save for a couple of white stripes; it has a long, bushy tail and very powerful claws on its fore feet. It walks on the sides of its fore feet with these claws curved in under the foot. The claws are used in digging out ant-hills; but the beast has courage, and in a grapple is a rather unpleasant enemy, in spite of its toothless mouth, for it can strike a formidable blow with these claws. It sometimes hugs a foe, gripping him tight; but its ordinary method of defending itself is to strike with its long, stout, curved claws, which, driven by its muscular forearm, can rip open man or beast. Several of our companions had had dogs killed by these ant-eaters; and we came across one man with a very ugly scar down his back, where he had been hit by one, which charged him when he came up to kill it at close quarters.
As soon as we saw the giant tamandua we pushed off in a rowboat, and landed only a couple of hundred yards distant from our clumsy quarry. The tamandua throughout most of its habitat rarely leaves the forest, and it is a helpless animal in the open plain. The two dogs ran ahead, followed by Colonel Rondon and Kermit, with me behind carrying the rifle. In a minute or two the hounds overtook the cantering, shuffling creature, and promptly began a fight with it; the combatants were so mixed up that I had to wait another minute or so before I could fire without risk of hitting a dog. We carried our prize back to the bank and hoisted it aboard the steamer. The sun was just about to set, behind dim mountains, many miles distant across the marsh.
Soon afterward we reached one of the outstations of the huge ranch we were about to visit, and hauled up alongside the bank for the night. There was a landing-place, and sheds and corrals. Several of the peons or gauchos had come to meet us. After dark they kindled fires, and sat beside them singing songs in a strange minor key and strumming guitars. The red firelight flickered over their wild figures as they squatted away from the blaze, where the light and the shadow met. It was still and hot. There were mosquitoes, of course, and other insects of all kinds swarmed round every light; but the steamboat was comfortable, and we passed a pleasant night.
At sunrise we were off for the "fazenda," the ranch of M. de Barros. The baggage went in an ox-cart—which had to make two trips, so that all of my belongings reached the ranch a day later than I did. We rode small, tough ranch horses. The distance was some twenty miles. The whole country was marsh, varied by stretches of higher ground; and, although these stretches rose only three or four feet above the marsh, they were covered with thick jungle, largely palmetto scrub, or else with open palm forest. For three or four miles we splashed through the marsh, now and then crossing boggy pools where the little horses labored hard not to mire down. Our dusky guide was clad in a shirt, trousers, and fringed leather apron, and wore spurs on his bare feet; he had a rope for a bridle, and two or three toes of each foot were thrust into little iron stirrups.
The pools in the marsh were drying. They were filled with fish, most of them dead or dying; and the birds had gathered to the banquet. The most notable dinner guests were the great jabiru storks; the stately creatures dotted the marsh. But ibis and herons abounded; the former uttered queer, querulous cries when they discovered our presence. The spurred lapwings were as noisy as they always are. The ibis and plover did not pay any heed to the fish; but the black carrion vultures feasted on them in the mud; and in the pools that were not dry small alligators, the jacare-tinga, were feasting also. In many places the stench from the dead fish was unpleasant.
Then for miles we rode through a beautiful open forest of tall, slender caranda palms, with other trees scattered among them. Green parakeets with black heads chattered as they flew; noisy green and red parrots climbed among the palms; and huge macaws, some entirely blue, others almost entirely red, screamed loudly as they perched in the trees or took wing at our approach. If one was wounded its cries kept its companions circling around overhead. The naturalists found the bird fauna totally different from that which they had been collecting in the hill country near Corumba, seventy or eighty miles distant; and birds swarmed, both species and individuals. South America has the most extensive and most varied avifauna of all the continents. On the other hand, its mammalian fauna, although very interesting, is rather poor in number of species and individuals and in the size of the beasts. It possesses more mammals that are unique and distinctive in type than does any other continent save Australia; and they are of higher and much more varied types than in Australia. But there is nothing approaching the majesty, beauty, and swarming mass of the great mammalian life of Africa and, in a less degree, of tropical Asia; indeed, it does not even approach the similar mammalian life of North America and northern Eurasia, poor though this is compared with the seething vitality of tropical life in the Old World. During a geologically recent period, a period extending into that which saw man spread over the world in substantially the physical and cultural stage of many existing savages, South America possessed a varied and striking fauna of enormous beasts—sabre-tooth tigers, huge lions, mastodons, horses of many kinds, camel-like pachyderms, giant ground- sloths, mylodons the size of the rhinoceros, and many, many other strange and wonderful creatures. From some cause, concerning the nature of which we cannot at present even hazard a guess, this vast and giant fauna vanished completely,
