A group of newly erected shacks, low and so lightly built of packing-cases and corrugated sheet iron that many of them resembled mere skeletons of houses; narrow, crooked streets; shops loaded with fruits and conducted by Italians, and others festooned with bandanna handkerchiefs, gaudy wearing apparel and cheap jewelry, and owned by Turks or Syrians; gambling and liquor houses; a motley crowd of slovenly, not overdressed people, and a tropical sun blazing down mercilessly on the whole assemblage. That is Embarcacion, the “farthest east” to date in the north-eastern part of Argentina’s vast Chaco. I was told that as the railroad is extended farther and farther into the interior, many of the residents take down their abodes and ship them to the new station where they are re-assembled; and so a great portion of the town moves bodily at different intervals. On all sides lies the seemingly limitless Chaco. There is practically no cultivation and but few herds of cattle had been introduced to date. In addition to the great possibilities for cattle-raising, the country also possesses enormous wealth in quebracho-wood; at present quantities of it are cut for use as fuel in the locomotives of several of the railroads. Within a short time, no doubt, these assets will be utilized in a manner that will be advantageous to both the exploiters and the country at large. One of the interesting discoveries in the pampas was a wintering-place for bobolinks. The extent of this bird’s migration had been shrouded in mystery, and but a single specimen in winter plumage had ever been recorded. We found them in flocks of thousands, perched in the top of the tall grass or picking up seeds from the ground. Their cheery song was conspicuously absent. They were in spotted plumage. Small red-breasted meadow-larks (_Leistes_) mingled freely with the bobolinks.
