Close to where we walked on those first days, we were later to find our best hunting. During the next few months all the more interesting animals of this part of South America were shot or their presence noticed; jaguars, tapirs, deer, peccaries, howling monkeys, vampires, agoutis, jaguarondis, otters, sloths, and armadillos. Hosts of birds, almost half the entire number of species found in the Colony, made their home hereabouts, macaws, bellbirds, curassows, trumpeters, toucans, the great harpy eagle and the tiniest of iridescent hummingbirds. Within a week our great front room, full thirty by sixty feet, with sixteen large windows, was a laboratory in appearance and odor. Hundreds of jars and vials, vivaria and insectaries, microscopes, guns, and cameras, with all their details and mysterious inner workings, left no table vacant. With book-shelves up, there remained only the walls, which little by little became mosaics of maps, diagrams, sketches, drying skins, Indian weapons, birds' nests and shot-holes. Whiffs of formaline, chloroform, and xylol, together with the odors of occasional mislaid or neglected specimens, left no doubt as to the character of the room. We found that the tradewind came from the front, and also that we had much to discuss after the lamps were put out; so we turned the couches into their rightful functions of cots, and the three of us slept scattered here and there in the great room. The vampire bats never allowed us to become bored. There were no mosquitoes or flies, so we used no nets; but for months we burned a lantern. Low around our heads swept the soft wings of the little creatures, while the bat enthusiast now and then fired his auxiliary pistol. Later we found that a score of them roosted behind a broken clapboard, and, by spreading a seine below and around this, we were able to capture and examine the entire colony at will. Tarantulas were common, but not in the least offensive, and we learned to know where to look for a big black fellow and a small gray one who kept the room free from cockroaches. One or two scorpions were caught indoors, but the three centipedes which appeared occasionally were those which had been brought in and were always escaping from a defective vivarium. There were no other dangers or inconveniences, if we can apply such terms to these comparatively harmless creatures.
