Yet I had no doubt that the message concerned something of far more importance than Benda"s own safety. He had moved in this matter with astonishing skill and breathless caution; yet I knew him to be reckless to the extreme where only his own skill was concerned. I couldn"t even imagine his going to this elaborate risk merely on account of Smith and Francisco. Something bigger must be involved.
I stared at the rows of specimens.
"Communication is a science!" Benda had said, and it came back to me as I studied the bent worms and the beetles with two legs missing. I was confident that the solution would be simple. Once the key idea occurred to me I knew I should find the whole thing astonishingly direct and systematic. For a moment I tried to attach some sort of heiroglyphic significance to the specimen forms; in the writing of the American Indians, a wavy line meant water, an inverted V meant a wigwam. But, I discarded that idea in a moment. Benda"s mind did not work along the paths of symbolism. It would have to be something mathematical, rigidly logical, leaving no room for guess-work.
No sooner had the key-idea occurred to me than the basic conception underlying all these rows of twigs and bugs suddenly flashed into clear meaning before me. The simplicity of it took my breath away.
"I knew it!" I said aloud, though I was alone. "Very simple."
I was prepared for the fact that each one of the specimens represented a letter of the alphabet. If nothing else, their number indicated that.
Now I could see, so clearly that the photographs shouted at me, that each specimen consisted of an upright stem, and from this middle stem projected side-arms to the right and to the left, and in various vertical locations on each side.
The middle upright stem contained these side-arms in various numbers and combinations. In five minutes I had a copy of the message, translated into its fundamental characters, as shown on Plate II.
[Ill.u.s.tration: Plate I]
The first gra.s.s-blade was the simple, upright stem; the second, three leaflets on their stem, represented the upright portion with two arms to the left at the top and middle, and one arm to the right at the top; and so on.
That brought the message down to the simple and straightforward matter of a subst.i.tution cipher. I was confident that Benda had no object in introducing any complications that could possibly be avoided, as his sole purpose was to get to me the most readable message without getting caught at it. I recollected now how cautious he had been to hand me no paper, and how openly and obviously he had dropped each specimen into my book; because he knew someone was watching him and expecting him to slip in a message. He had, as I could see now in the retrospect, been conspicuously careful that nothing suspicious should pa.s.s from his hands to mine.
[Ill.u.s.tration: Plate II]
Subst.i.tution ciphers are easy to solve, especially for those having some experience. The method can be found in Edgar Allen Poe"s "Gold Bug" and in a host of its imitators. A Secret Service cipher man could have read it in an hour. But I knew my friend"s mind well enough to find a short-cut. I knew just how he would go about devising such a cipher, in fact, how ninety-nine persons out of a hundred with a scientific education would do it.
If we begin adding horizontal arms to the middle stem, from top to bottom and from left to right, the possible characters can be worked out by the system shown on Plate III.
[Ill.u.s.tration: Plate III]
It is most logical to suppose that Benda would begin with the first sign and subst.i.tute the letters of the alphabet in order. That would give us the cipher code shown on Plate IV.
It was all very quick work, just as I had antic.i.p.ated, once the key-idea had occurred to me. The ease and speed of my method far exceeded that of Poe"s method, but, of course, was applicable only to this particular case. Subst.i.tuting letters for signs out of my diagram, I got the following message:
AM PRISONER R PLANS CAPTURE OF N Y BY SEIZING POWER WATER AND PHONES THEN WORLD CONQUEST S O S

_L"Envoi_
(By Peter Hagstrom, M.D.)
My solution of the message practically ends the story. Events followed each other from then on like bullets from a machine-gun. A wild drive in a taxicab brought me to the door of Mayor Anderson at ten o"clock that night. I told him the story and showed him my photographs.
Following that I spent many hours telling my story to and consulting with officers in the War Department. Next afternoon, photographic maps of the Science Community and its environs, brought by airplanes during the forenoon, were spread on desks before us. A colonel of marines and a colonel of aviation sketched plans in notebooks. After dark I sat in a transport plane with m.u.f.fled exhaust and propellers, slipping through the air as silently as a hawk. About us were a dozen bombing planes, and about fifty transports, carrying a battalion of marines.
I am not an adventure-loving man. Though a cordon of husky marines about me was a protection against any possible danger, yet, stealing along through that wild valley in the Virginia mountains toward the dark ma.s.ses of that fanatic city, the silent progress of the long, dark line through the night, their mysterious disappearance, one by one, as we neared the city, the creepy, hair-raising journey through the dark streets--I shall never forget for the rest of my life the sinking feeling in my abdomen and the throbbing in my head. But I wanted to be there, for Benda was my lifelong friend.
I guided them to Rohan"s rooms, and saw a dozen dark forms slip in, one by one. Then we went on to the dormitory where Benda lived. Benda answered our hammering at his door in his pajamas. He took in the Captain"s automatic, and the bayonets behind me, at a glance.
"Good boy, Hagstrom!" he said. "I knew you"d do it. There wasn"t much time left. I got my instructions about handling the New York telephone system to-day."
As we came out into the street. I saw Rohan handcuffed to two big marines, and rows of bayonets gleaming in the darkness down the streets.
Every few moments a bright flare shot out from the planes in the sky, until a squad located the power-house and turned on all the lights they could find.

Jetta of the Lowlands
BEGINNING A THREE-PART NOVEL
By Ray c.u.mmings
_Foreword_
_Have you ever stood on the seash.o.r.e, with the breakers rolling at your feet, and imagined what the scene would be like if the ocean water were gone? I have had a vision of that many times. Standing on the Atlantic Coast, gazing out toward Spain, I can envisage myself, not down at the sea-level, but upon the brink of a height. Spain and the coast of Europe, off there upon another height._
[Sidenote: Fantastic and sinister are the Lowlands into which Philip Grant descends on his dangerous a.s.signment.]
_And the depths between? Unreal landscape! Mysterious realm which now we call the bottom of the sea! Worn and rounded crags; bloated mud-plains; noisome reaches of ooze which once were the cold and dark and silent ocean floor, caked and drying in the sun. And off to the south the little fairy mountain tops of the West Indies rearing their verdured crowns aloft._
[Ill.u.s.tration: "Look around, Chief. See where I am?"]
_If the ocean water were gone! Can you picture it? A new world, greater in area than all the land we now have. They would call the former sea-level the zero-height, perhaps. The depths would go down as far beneath it as Mount Everest towers above it. Aeroplanes would fly down into them._
_And I can imagine the settlement of these vast new realms: New little nations being created, born of man"s indomitable will to conquer every adverse condition of inhospitable nature._
_A novel setting for a story of adventure. It seems so to me. Can you say that the oceans will never drain of their water? That an earthquake will not open a rift--some day in the future--and lower the water into subterranean caverns? The volume of water of all the oceans is no more to the volume of the earth than a tissue paper wrapping on an orange._
_Is it too great a fantasy? Why, reading the facts of what happened in 1929, it is already prognosticated. The fishing banks off the Coast of Newfoundland have suddenly sunk. Cable ships repairing a broken cable, snapped by the earthquake of November 18th, 1929, report that for distances of a hundred miles on the Grand Banks the cables have disappeared into unfathomable depths. And before the subterranean cataclysm, they were within six hundred feet of the surface. And all the bottom of that section of the North Atlantic seems to have caved in. Ten thousand square miles dropped out of the bottom of the ocean! Fact, not fancy._
_And so let us enlarge the picture. Let us create the Lowlands--twenty thousand feet below the zero-height--the setting for a tale of adventure. The romance of the mist-shrouded deeps. And the romance of little Jetta._
CHAPTER I
_The Secret Mission_
I was twenty-five years of age that May evening of 2020 when they sent me south into the Lowlands. I had been in the National Detective Service Bureau, and then was transferred to the Customs Department, Atlantic Lowlands Branch. I went alone; it was best, my commander thought. An a.s.signment needing diplomacy rather than a show of force.
It was 9 P. M. when I catapulted from the little stage of Long Island airport. A fair, moonlit evening--a moon just beyond the full, rising to pale the eastern stars. I climbed about a thousand feet, swung over the headlands of the Hook, and, keeping in the thousand-foot local lane, took my course.
