"Why, I guess our man has figured this thing all out. Brought this pole up from the beach to plant it here. Why? Because this was the best observation point. No good as a permanent residence, though. Planted his flag and went back."
"Why didn"t we see him on the beach, then?"
"Did you notice a cave around to the north? Good refuge in case of fumes."
"It"s worth trying," said the captain, putting up his gla.s.s.
"Hold on, sir. What"s this? Here"s something. Look here."
Trendon pointed to a small bit of wood rather neatly carved to the shape of an indicatory finger, and lashed to the staff, at the height of a man"s face. The others cl.u.s.tered around.
"Oh, the devil!" cried Trendon. "It must have got twisted. It"s pointing straight down."
"Strange performance," said the captain. "However, since it points that way--heave aside those rocks, men."
The first slab lifted brought to light a corner of cardboard. This, on closer examination, proved to be the cover of a book. The rocks rolled right and left, and as the flag-staff, deprived of its support, tottered and fell, the trove was dragged forth and handed to the captain. While the ground jarred with occasional tremors and the mountain puffed forth its vaporous threats, he and the surgeon, seated on a rock, gave themselves with complete absorption to the reading.

THE CACHE
Outwardly the book accorded ill with its surroundings. In that place of desolation and death, it typified the petty neatness of office processes.
Properly placed, it should have been found on a desk, with pens, rulers, and other paraphernalia forming exact angles or parallels to it. It was a quarto, bound in marbled paper, with black leather over the hinges. No external label suggested its ownership or uses, but through one corner, blackened and formidable in its contrast to the peaceful purposes of the volume, a hole had been bored. The agency of perforation was obvious. A bullet had made it.
"Seen something of life, I reckon," said Trendon, as the captain turned the volume about slowly in his hands.
"And of death," returned Captain Parkinson solemnly. "Do you know, Trendon, I almost dread to open this."
"Pshaw!" returned the other. "What is it to us?"
He threw the cover back. Neatly lettered on the inside, in the fine and slightly angular writing characteristic of the Teutonic scholar, was the legend:
Karl Augustus Schermerhorn, 1409-1/2 Spruce Street, Philadelphia, Pa.
[Ill.u.s.tration: With a strangled cry the sailor cast the shirt from him]
The opposite page was blank. Captain Parkinson turned half a dozen leaves.
"German!" he cried, in a note of disappointment, "Can you read German script?"
"After a fashion," replied the other. "Let"s see. _Es wonnte sechs--und-- dreissig unterjacke_," he read. "Why, blast it, was the man running a haberdashery? What have three dozen undershirts to do with this?"
"A memorandum for outfitting, probably," suggested the captain. "Try here."
"Chemical formulae," said Trendon. "Pages of "em. The devil! Can"t make a thing of it."
"Well, here"s something in English."
"Good," said the other. "_By combining the hyper-sulphate of iridium with the fumes arising from oxide of copper heated to 1000 C. and combining with picric acid in the proportions described in formula x 18, a reaction, the nature of which I have not fully determined, follows. This must be performed with extreme care owing to the unstable nature of the benzene compounds._"
"Picric acid? Benzene compounds? Those are high explosives," said Captain Parkinson. "We should have Barnett go over this."
"Here"s a name under the formula. _Dr. A. Mardenter, Ann Arbor, Mich_.
That explains its being in English. Probably copied from a letter."
"This must have been one of the experiments in the valley that Slade told us of," said the captain, thoughtfully. "Why, see here," he cried, with something like exultation. "That"s what Dr. Schermerhorn was doing here.
He has the clue to some explosive so terrific that he goes far out of the world to experiment with its manufacture. For companions he chooses a gang of cutthroats that the world would never miss in case anything went wrong.
Possibly it was some trial of the finished product that started the eruption, even. Do you see?"
"Don"t explain enough," grunted Trendon. "Deserted ship. Billy Edwards.
Mysterious lights. Slade and his story. Any explosives in those? Good enough, far as it goes. Don"t go far enough."
"It certainly leaves gaps," admitted the other.
He turned over a few more pages.
"Formulas, formulas, formulas. What"s this? Here are some marginal annotations."
"Unbeha.s.slich," read Trendon. "Let"s see. That means "highly unsatisfactory," or words to that effect. Hi! Here"s where the old man loses his temper. Listen: _"May the devil take Carroll and Crum for careless"_--h"m--well, _"pig-dogs."_ Now, where do Carroll and Crum come in?"
"They"re a firm of a.n.a.lytical chemists in Washington," said the captain.
"When I was on the ordnance board I used to get their circulars."
"Fits in. What? More English? Worse than the German, this is."
The writing, beginning evenly enough at the top of a page, ran along for a line or two, then fell, sprawling in huge, ragged characters the full length. Trendon stumbled among them, indignantly.
"_June 1, 1904_," he read. "_It is done. Triumph_. (German word.) _Eureka.
Es ist gefillt. From the_ (can"t make out that word) _of the inspiration--G.o.d-like power--solution of the world-problems_. Why, the old fool is crazy! And his writing is crazier. Can"t make head or tail of it."
The captain turned several more pages. They were blank. "At any rate, it seems to be the end," he said.
"I should hope so," returned the other, disgustedly.
He took the book on his knees, fluttering the leaves between thumb and finger. Suddenly he checked, cast back, and threw the book wide open.
"Here beginneth a new chapter," said he, quietly.
No imaginable chirography could have struck the eye with more of contrast to the professor"s small and nervous hand. Large, rounded, and rambling, it filled the page with few and careless words.
_June 2, 1904. On this date I find myself sole occupant and absolute monarch of this valuable island. This morning I was a member of a community, interesting if not precisely peaceful. To-night I am the last leaf. "All his lovely companions are faded and gone," the sprightly Solomon, the psychic n.i.g.g.e.r, the amiable Thrackles, the cheerful Perdosa, the genial Pulz, and the high-minded Eagen. Undoubtedly the social atmosphere has cleared; moreover, I am for the first time in my life a landed proprietor. Item: several square miles of gra.s.s land; item: several dozen head of sheep; item: a cove full of fish; item: a handsomely decorated cave; item: a sportive though somewhat unruly volcano. At times, it may be, I shall feel the lack of company. The seagulls alone are not distrustful of me. Undoubtedly the seagull is an estimable creature, but he leaves something to be desired in the way of companionship. Hence this diary, the inevitable refuge of the empty-minded. Materially, I shall do well enough, though I face one tragic circ.u.mstance. My cigarette material, I find, is short. Upon counting up--"_
"d.a.m.n his cigarettes!" cried the surgeon. "This must be Darrow. Finicky beast! Let"s see if it"s signed."
He whirled the leaves over to the last sheet, glanced at it, and sprang to his feet. There, sprawled in tremulous characters, as by a hand shaken with agony or terror, was written:
