"I imagine that German colonial life is far worse than death," said I.

"German will be the only rule in Africa," he answered. "You fools of English have set your hopes on the Christian missionary. No weaker-backed camel could exist! The German Michael is wiser! Islam is the key to the native mind--Islam and the lash--they understand that! In a few years there will be nothing in Africa that is not German from core to epidermis! As to whether you shall live to see that day or not depends on yourself, my young friend!"

Being quite sure that he had a plan in mind that nothing would prevent him from unfolding, I did not waste effort or words on prompting him, but sat still. My silence and apparent lack of curiosity disturbed him; there is nothing your bully likes better than to force his victim into a war of words.

"I will be short and blunt with you!" he began again. "I know your history! You were in Portuguese Africa with Lord Montdidier. There he came in possession of the secret of Tippoo Tib's ivory; how, I do not yet know, but you shall tell me that presently! You and your friends came with him to Zanzibar, where you made certain inquiries--sufficient to set the Sultan of Zanzibar by the ears. You left Zanzibar for Mombasa, and for some reason that you shall also tell me presently, Lord Montdidier did not leave the ship at Mombasa but continued the voyage toward London. Certain individuals decided that it would be better not to permit Lord Montdidier to reach Europe alive. There were agents charged with the duty of attending to that. It was considered safest to throw him overboard into the Mediterranean; men were ordered by cable to board the ship at Suez. Yet when the ship reached Suez n.o.body knew anything about him! Tell me where he left the ship, and why!"

He glared with eyes accustomed to extorting facts from savages, depending on physical weakness so to undermine my will that I would give my secret away, perhaps without knowing it.

I lowered my eyes, not being minded to match the strength of my eye-muscles against his. The news that Monty had not reached Suez as a matter of fact made me feel physically sick. If it were true, it meant most likely that he had been the victim of foul play, for that steamer was not scheduled to stop anywhere before reaching the Suez Ca.n.a.l. As for the people on the ship knowing nothing about him they no doubt preferred not to talk to strangers. That sort of news is easily kept under cover for a while. Schillingschen grew angry at my silence, and changed his tactics.

"Where did he leave the ship?" he shouted--suddenly--savagely.

I did not answer. He came round to my side of the grave, and laid a heavy clenched fist on my shoulder. It seemed to weigh like lead in the weak condition I was in.

"You shall tell me what Lord Montdidier is doing now, or that grave shall resemble in your imagination a bed of roses!"

He seized my neck in a grasp like iron, and squeezed it. I rose suddenly and struck him in the stomach with my elbow. Strength had returned more swiftly than I had guessed, or perhaps it was indignation at the touch of his fingers. At any rate he staggered clear of me, and I thought he would a.s.sault me now in real earnest; but perhaps he suspected me of having weapons concealed somewhere. Instead of rushing at me like an angry bull he calmed himself and laughed.

"You are strong for a man they thought of burying!"' he said. "Never mind! You shall see reason presently! It is well understood that you and your friends know where Tippoo Tib's ivory is hidden. You imagine you can keep the secret. If you keep it, you shall never make use of it, my young friend! If you choose to tell, you shall be suitably rewarded! Come now--I thought you were going to look for it down in these parts. I admit you fooled me. You simply made a false move to draw attention off from Lord Montdidier. Tell me where he is and what he does--and--or--"

"And what? Or what?" I demanded, as insolently as I knew how. I saw no sense in answering him gently.

"I will show you!"

I had begun to feel weak again, but he offered me an arm, and since he seemed in no hurry I was able to struggle along beside him. We took to the main road and when we reached the D.O.A.G. he called for a hammock and some porters. Being carried in that way was sheer luxury after the walk in my weak state, and I lay back feeling like a tripper on vacation. I saw Fred and Will climbing down from their observation post on top of the Bismarck monument, but he did not notice them.

Every German sergeant, and every askari we pa.s.sed saluted us with about twice as much respect as I had ever seen them show the commandant; and Schillingschen returned salutes much less carefully than he, merely by a curt nod, or one raised finger. Apparently the military feared him, for when we pa.s.sed the commandant, who was personally superintending the flogging of two natives in the market-place for not saluting himself, he took several paces forward to make sure Schillingschen should see his act of homage. The professor merely nodded in return, and I began to I wonder whether there was a rift in the lute of Muanza's official good relations. Surely I hoped so. Anything calculated to set the Germans' garrison life at odds looked to me like the gift of heaven!

Schillingschen, striding beside the hammock, directed our course along the sh.o.r.e-front under palm-trees, planted in stately rows with meticulous precision. He kept far enough to one side to avoid the charge of being seen walking with me, but from time to time tossed me remarks calculated to keep my nerves on edge.

"What I shall show you is by way of warning!" was a remark he repeated two or three times. Then: "A native can always be made to talk by flogging him. Some white men need sterner measures!"

We left the commandant's house on the hill far behind and followed the curve of the lake sh.o.r.e, toward a rocky promontory with a clump of thick jungle behind it. Fear began to get its work in, until the thought came that what he most desired was to make me afraid; then I managed to summon sufficient contempt for him and his tribe to regain my nerve and once more almost enjoy the promenade.

He halted the hammock bearers at a spot about three hundred yards away from the promontory and, leaving them standing there, turned inland with a hand on my arm to give me support and direction. We followed a path that was fairly well marked out and trodden, but rough, and several times I should have fallen but for his help. My legs still refused any sort of strenuous duty.

"The staff surgeon at this station is a man of ideas," he announced as we rounded a big rock and pa.s.sed down a narrow glade in the jungle.

"He is original. He is not like some of our official fools. He studies."

I refused to seem curious, and walked beside him in silence.

"He studies sleeping sickness. If he can find the key to the solution of that scourge it will mean promotion for him. He has noticed that the sleeping sickness is always at its worst beside the lake, and putting two and two together like a sensible man has reached the conclusion that the disease may be propagated in some way in the blood of these things."

We emerged into a clearing in which a pool more than a hundred yards long and nearly as many wide was formed naturally by a hollow in the surface of a great sheet of granite. The pool was fed by a trickle of water from a jumble of rocks at one end. At the other end the bottom of the pond sloped upward gradually, so that a ramp of smooth rock was formed, emerging out of shallow water. A stone wall had been built about three feet high to enclose that end of the pond, and all the way along both sides the granite had been broken and chipped until the edges were sheer and unclimbable.

"Look!" he said, pointing.

I looked and grew sick. On the ramp, half in the water and half out lay about a hundred crocodiles basking in the sun, their yellow eyes all open. They were aware of us, for they began to move slowly higher out of water as if they expected something.

"You see that post?" asked Schillingschen.

The stump of a dead tree that he referred to stood up nearly straight out of a crack in the rock, and a few yards above water level. The crocodiles all lay nose toward it, some of them twelve or fourteen feet long, some smaller, and some very small indeed, all interested to distraction in the dead tree-trunk.

"That is where he feeds them," Schillingschen announced. "He has tested them for hearing, smell, and eyesight. By making fast a living animal to that post be has been able to convince himself that from about nine in the morning until five in the afternoon their senses are limited. Only occasionally do they come and take the bait between those hours. They are hungriest in the early morning just before daylight. Recently a large ape tied to the post at midday was not killed and eaten until four next morning, and that is about the usual thing, although not the rule. Now my proposal is--"

He stepped back and eyed me with the coldest look of appraisal I ever sickened under. I blenched at last--visibly suffered under his eye, and he liked it.

"--that you tell your secret or be fastened to that post from noon, say, until the crocodiles make an end of you!"

He stepped back a pace farther, perhaps to gloat over my discomfort, perhaps from fear of some concealed weapon.

"You have not much time to arrive at your decision!"

He took another pace backward. It occurred to me then that he was looking for some one he expected. n.o.body turning up, he began to gather loose stones and throw them at the reptiles, driving them down into deep water, first in ones and twos and then by dozens. Most of them swam away to the far side of the pool, and hid themselves where it was deep.

Then, panting with having run, there came a native who looked like a Zulu, for he had enormous thighs and the straight up and down carriage, as well as facial characteristics.

"You are late!" shouted Schillingschen in German "Warum? What d'ye mean by it?"

The man opened his mouth wide and made grimaces. He had no tongue.

Schillingschen laughed.

"This is a servant who does no tattling in the market-place!" he said, turning again toward me. "He and I can tie you to that post easily.

What do you say?"

There was nothing whatever to say, or to do except wonder how to circ.u.mvent him, and nothing in sight that could possibly turn into a friend--except a little tuft of faded brown that out of the corner of my eye I detected zigzagging toward me in the direction from which we had come. A moment later I knew it really was a friend. "Crinkle," a mongrel dog that Fred had adopted the day after our arrival, breasted the low rise, saw me, gave a yelp of delight and came scampering.

The dog sniffed my knee to make sure of me, and then trotted over to sniff Schillingschen. The professor stooped down to pat him, rubbed his ear a moment to get the dog's confidence, and then seized him suddenly by both hind legs. I saw what he intended too late.

"Stop, or I'll kill you!" I shouted, and made a rush at him. But he swung the yelping dog and hurled him far out into the pool.

A second later my fist crashed into his face and he staggered backward.

A second later yet the dumb Zulu pinned my elbows from behind and set his knee into the small of my back with such terrific force that I yelled with pain. Then Schillingschen approached me and began to try to drive my teeth in with unaccustomed fists. He loosened my front teeth, but cut his own knuckles, so began looking about for a stick.

Strangely enough my own attention was less fixed on Schillingschen than on the wretched "Crinkle" swimming frantically for sh.o.r.e. Dog-like he was making straight for me, and there was no possibility whatever of his being able to scramble up the steep side. I shouted to call his attention, and tried to motion to him to swim toward shallow water, but the Zulu would not let my arms free, and the dog only thought I was urging him to hurry.

Schillingschen found a stick and came back to give me a hammering with it just at the moment when a crocodile saw "Crinkle." A blow landed on my head, cut my forehead, and sent the blood down into my eyes at the same moment that I heard the dog's yelp of agony; and next time I looked at the pond there was a tiny whirlpool on the surface, slightly tinged with red.

"You swine!" I shouted at Schillingschen, trying to break loose and attack him. For answer he raised his cudgel in both hands and stood on tiptoe to get leverage. If that blow had landed it must have broken something, for he was strong as a gorilla; but somebody shouted--I recognized Fred's voice, and in another second he and Will charged down on us. Schillingschen turned about to strike Fred instead of me, but Will's fist hit him on the ear and split it. The professor staggered backward, and a moment later Fred had felled the Zulu. I reeled from weakness and excitement, and nearly fell down.

"Throw him to the crocks, you men!" I urged madly. "He threw Crinkle in. Throw him! n.o.body'll ever know! He'd have dared throw me in!

n.o.body comes here! Throw him in and trust the crocks to leave no trace!"

"Shut up, you fool!" growled Fred.

"Did you see him throw that dog in?" I retorted.
