“Imagine, Doctor, such a spectacle! I had brought a lot of mosquito netting—pink, it was—and with that I had shown the savages how to make insect nets. Such a sight! Forty or fifty Indians and bush-niggers, some naked except for a fawn-colored opera hat and a pair of iron spectacles without the lenses; others swathed in flaming calico prints, sitting around my camp blowing into a harmonica or a jew’s-harp, or sneaking through the jungle with shrimp-pink butterfly net! The very crocodiles used to crawl out upon the banks and laugh! And the natives all so proud and pleased!

“Then one day a few of them came in and said that they had trapped a maipuri—a kind of water-tapir—over on the other bank. I took a few men and went over to superintend the skinning of the beast, and while so engaged two of the Indians came rushing up to say that a small steamer was coming up the river.

“It turned out to be a little gunboat. Shortly after we left Bolivar there had been one of the semi-annual revolutions, and the new governor of the district, knowing that I had gone up the river, had come up to see what could be made out of me. The matter could have been arranged peaceably enough had it not been for Frederick. On sighting the steamer the fool had promptly armed the boat crews, and when the people from the gunboat landed near the camp they were confronted by an array of twenty half-caste Caribs, armed with bored-out Springfields, and about two-score of Indians, gorgeously equipped with opera hats and spectacles, many of them blowing furiously into harmonicas and all armed with bows and spears.

“Those Indians, as you know, are the most harmless people in the world, but the Caribs will fight, and from all I could learn, for I was across the river at the time, that fool of a Frederick went roaring about, making frenzied orations and challenging the Venezuelans to try to land.

“They did land, and at the first volley Frederick rolled on his back, absolutely unhurt, and howled for mercy. The Caribs retreated firing, and managed to kill one of the people from the gunboat and wound three others. I started back the moment I heard the firing, but by that time my allies had been routed, and I was promptly arrested and put down below in double irons.

“They confiscated all of my specimens, stowing them away on the gunboat, took the boats in tow and down the river we went, leaving the Indians and boatmen in the bush. All of my protests were vain; I had been trading without a license from the government—which did not exist when I went up—in addition to which my people had fired upon government troops, killing a man and wounding others. No appeal to my consul would be permitted; I was no better than a pirate, etc.

“Frederick was chained up near me on the trip down, and he alternated between raving curses at our captors and whimpering like a pup when they cuffed him for it. You see, Doctor, the alien strains were always at work in that man. One minute he was white, the next black. Your French or Spanish or Italian half-caste would have had the cunning that is one of the compensations of the mongrel; but Frederick was in two layers, and sometimes one would be on top and sometimes the other, but they never mixed. It was even so with his personal appearance, for I noticed that when he was in charge of our men he looked the typical German; his features were aquiline, composed, dignified and showed character. On the other hand, when he was hurt or frightened the actual color of his skin was all that proclaimed him white. His eyes would bulge until the whites were visible all the way around, his forehead crept down, his nose would actually flatten and his lips rolled back in the typical African manner, showing their red linings and the big ivory teeth.

“Before we had reached the mouth of the river he was moping in the usual negro way, and I think that he would have died, as negroes will if their despondency lasts too long, had we been a week longer en voyage.”

Leyden ceased speaking and jerked his head irritably toward the fat Italian who had been playing chess with the captain. He had fallen asleep in his chair, and, being a large man, his head had rolled back over the cross-bar. A shaft of light from the “rook kamer” fell upon the expanse of pale, flabby throat, stretched tense by the weight of the pendant head, and as I glanced that way it vibrated with strangling, unwholesome noises.

Humbert!” called Leyden, in a soft, feminine voice, then quickly turned his back. The sodden mass convoluted; the noises culminated in a strangling snort; one almost heard the vertebræ creak as the strain came upon them; then he sat up and stared about in bewilderment.
