THE GREAT DROUGHT.

By Capt. S. P. Meek

"Is the maneuver progressing as you wish. Dr. Bird?" asked the Chief of the Air Corps.

The famous scientist lowered his binoculars and smiled.

"Exactly, General," he replied. "They are keeping a splendid line."

"It is the greatest concentration of air force that this country has ever seen," said General Merton proudly.

With a nod, Dr. Bird raised his gla.s.ses to his eyes and resumed his steady gaze. Five thousand feet below and two miles ahead of the huge transport plane which flew the flag of the Chief of the Air Corps, a long line of airplanes stretched away to the north and to the south. Six hundred and seventy-two planes, the entire First Air Division of the United States Army, were deployed in line at hundred-yard intervals, covering a front of nearly forty miles. Fifteen hundred feet above the ground, the line roared steadily westward over Maryland at ninety miles an hour. At ten-second intervals, a puff of black dust came from a discharge tube mounted on the rear of each plane. The dust was whirled about for a moment by the exhaust, and then spread out in a thin layer, marking the path of the fleet.

"I hope the observers on the planes are keeping careful notes of the behavior of those dust clouds," said Dr. Bird after an interval of silence. "We are crossing the Chesapeake now, and things may start to happen at any moment."

"They're all on their toes, Doctor," replied General Merton. "I understood in a general way from the President that we are gathering some important meteorological data for you, but I am ignorant of just what this data is. Is it a secret?"

Dr. Bird hesitated.

"Yes," he said slowly, "it is. However, I can see no reason why this secret should not be entrusted to you. We are seeking a means of ending the great drought which has ravaged the United States for the past two years."

Before General Merton had time to make a reply, his executive officer hastened forward from the radio set which was in constant communication with the units of the fleet.

"Two of the planes on the north end of the line are reporting engine trouble, sir," he said.

Dr. Bird dropped his gla.s.ses and sat bolt upright.

"What kind of engine trouble?" he demanded sharply.

"Their motors are slowing down for no explainable reason. I can't understand it."

"Are their motors made with sheet steel cylinders or with duralumin engine blocks?"

"Sheet steel."

"The devil! I hadn't foreseen this, although it was bound to happen if my theory was right. Tell them to climb! Climb all they know! Don't let them shut off their motors for any reason, unless they are about to crash. Turn this ship to the north and have the pilot climb--fast!"

A nod from General Merton confirmed the doctor's orders. The line of planes kept on to the west, but the flagplane turned to the north and climbed at a sharp angle, her three motors roaring at full speed. With the aid of binoculars, the two ships in trouble could be picked out, falling gradually behind the line. They were flying so slowly that it seemed inevitable that they would lose flying speed and crash to the ground.

"More speed!" cried the doctor. "We've elevation enough!"

The altimeter stood at eight thousand feet when the pilot leveled out the flagplane and tore at full speed toward the laboring ships. The main fleet was twenty miles to the west.

They were almost above the point where the two planes had first began to slow down. As they winged along, the three motors of the flagplane took on a different note. It was a laboring note, pitched on a lower scale. Gradually the air-speed meter of the ship began to show a lower reading.

"Locate us on the map, Carnes!" snapped Dr. Bird.

Operative Carnes of the United States Secret Service bent over a large-scale map of Maryland, spread open on a table. With the aid of the navigating officer, he spotted on the map the point over which the plane was flying.

"There goes Burleigh's ship!" cried the executive officer.

There was a gasp from the occupants of the flagplane's cabin. Far below them, one of the crippled planes had slowed down until it had lost flying speed. Whirling like a leaf, it plunged toward the ground. Two small specks detached themselves from the falling ma.s.s. They hovered over the falling plane for an instant. Suddenly a patch of white appeared in the air, and then another. The two specks fell more slowly.

"Good work!" exclaimed General Merton. "They took to their 'chutes just in time."

"We'll be taking them in a few minutes if our motors don't pick up!" replied the executive officer.

Far below them, the doomed plane crashed to the ground. As it struck there was a blinding flash followed by vivid flames as the gasoline from the bursted tank ignited. The two members of the crew were drifting to the east as they fell. It was evident that they were in no danger.

"Where is Lightwood's plane?" asked General Merton anxiously.

"It's still aloft and making its way slowly north. He intends to try for an emergency landing at the Aberdeen Proving Ground field," replied the executive officer.

"That's where we had better head for," said Dr. Bird. "I hope that the charge on Captain Lightwood's plane discharges through the tail skid when he lands. If it doesn't, he'll be in serious danger. Follow him and we'll watch."

Five thousand feet below them, the crippled plane limped slowly along toward Aberdeen. It was gradually losing elevation. Two specks suddenly appeared in the air, followed by white patches as the parachutes opened. Captain Lightwood and his gunner had given up the unequal fight and taken to the air. As the ship struck the ground, again there was a blinding flash, followed by an inferno of roaring flames.

"We're not in much better shape than they were, General," said the executive officer as he came back from the control room where the pilots were heroically striving to keep their motors turning over fast enough to keep up flying speed. "We'd better get into our 'chutes."

"The Proving Ground is just ahead," said the doctor. "Can't we make it by sacrificing our elevation?"

"We're trying to do that, Doctor, but we're down to four thousand now and falling fast. Get ready to jump."

Dr. Bird buckled on the harness of the pack parachute which the executive officer offered him. The rest of the crew had hurriedly donned their packs and stood ready.

For another five minutes the plane struggled on. Suddenly a large flat expanse of open ground which had been in sight for some time, seemed to approach with uncanny rapidity.

"There's the landing field!" cried the General. "We'll make it yet!"

Lower and lower the plane sank with the landing field still too far away for comfort. The pilot leveled off as much as he dared and drove on. The motors were laboring and barely turning over at idling speed. They pa.s.sed the nearer edge of the field with the flagplane barely thirty feet off the ground. In another moment the wheels touched and the plane rolled to a halt.

"Don't get out!" cried Dr. Bird.

He looked around the cabin and picked up a coil of bare antenna wire which hung near the radio set. He wrapped one end of the wire around the frame of the plane. To the other end, he attached his pack 'chute.

"Open the door!" he cried.

As the door swung open, he threw the 'chute out toward the ground. As it touched, there was a blinding flash, followed by a report which shook the plane. A strong odor of garlic permeated the air.

"All right!" cried the doctor cheerfully. "All out for Aberdeen. The danger is past."

He set the example by jumping lightly from the plane. General Merton followed more slowly, his face white and his hands shaking.

"What was it, Doctor," he asked. "I have been flying since 1912, yet I have never seen or heard of anything like that."

"Just a heavy charge of static electricity," replied the doctor. "That was what magnetized your cylinder walls and your piston rings and slowed your motors down. It was the same thing that wrecked those two ships. Unless it leaks off, the men of some of your other ships are due to get a nasty shock when they land to-night. I discharged the charge we had collected through a ground wire. Here comes a car, we'll go up to Colonel Wesley's office. Carnes, you have these maps?"

"Surely, Doctor."

"All right, let's go."

"But what about this ship, Doctor?" objected the General. "Can't something be done about it?"

"Certainly. I hadn't forgotten it. Have your crew stand by. I'll telephone Washington and have some men with apparatus sent right down from the Bureau of Standards. They'll have it ready for flying in the morning. We'll also have search parties sent out in cars to locate the crews of those abandoned ships and bring them in. Now let's go."

Colonel Wesley, the commanding officer of the Aberdeen Proving Ground, welcomed Carnes and Dr. Bird warmly.

"I'll tell you, General Merton," he said to the Chief of the Air Corps, "if you ever get up against something that is beyond all explanation, you want to get these two men working on it. They are the ones who settled that poisoning case here, you know."

"Yes, I read of that," replied the general. "I am inclined to think that they are up against something even queerer right now."

Colonel Wesley's eyes sparkled.

"Give your orders, Dr. Bird!" he cried. "Since our last experience with you, you can't give an order on this post that won't be obeyed!"

"Thank you, Colonel," said Dr. Bird warmly. "One reason why I came here was that I knew that I could count on your hearty cooperation. The first thing I want is two cars. I want them sent out to bring in the crews of two ships which were abandoned some eight miles south of here. Carnes will locate them on the map for your drivers."

"They'll be ready to start in five minutes, Doctor. What next?"

"Turn out every man and every piece of transportation you have to-morrow morning. I want the men armed. They will have to search a stretch of swamp south of here, inch by inch, until they find what I'm looking for."

"They'll be ready, Doctor. Would it be indiscreet for me to ask what it's all about?"

"Not at all, Colonel. I was about to explain to General Merton when trouble started. I am searching for the cause of the great drought which has been afflicting this country for the past two years. If I can find the cause, I hope to end it."

"Oh! I had a sneaking hope that we were in for another skirmish with that Russian chap, Saranoff, whose men started that poison here."

"I rather think we are, Colonel Wesley."

General Merton laughed.

"I'll swallow a good deal, Dr. Bird," he said, "but when you talk of an individual being responsible for the great drought, it's a little too much. A man can't control the weather, you know!"

"Yet a man, or an incarnate devil--I don't know which he is--did control the weather once, as well as the sun. But for the humble efforts of two Americans, aided by a Russian girl whose brother Saranoff had murdered, he might be still controlling it."

General Merton was silent now.

"Carnes, let me have that map," went on the doctor. When the detective had unrolled a map of the United States on Colonel Wesley's table, Dr. Bird continued, pointing to the map as he spoke.

"On this map," he said, "is plotted the deficiency in rainfall for the past year, from every reporting station in the United States. These red lines divide the country into areas of equal deficiency. The area most affected, as you can see, is longer east and west, than it is north and south. It is worst in the east, in fact in this very neighborhood. Even a casual glance at the map will show you that the center of the drought area, from an intensity standpoint, lies in Maryland, a few miles south of here."

"In fact, just about where those two planes went down," added Carnes.

"Precisely, old dear. That was why we went over that section with the fleet. Now, gentlemen, note a few other things about this drought. The areas of drought follow roughly the great waterways, the Ohio and the Potomac valleys being especially affected. In other words, the drought follows the normal air currents from this point. If something were to be added to the air which would tend to prevent rain, it would in time drift, just as the drought areas have drifted."

General Merton and Colonel Wesley bent over the map.

"I believe you're right, Doctor," admitted the general.

"Thank you. The President was convinced that I was before he placed the First Air Division under my orders. Frankly, that search was the real object of a.s.sembling the fleet. The maneuvers are a mere blind."

General Merton colored slightly.

"Now, I'll try to give you some idea of what I think is the method being used," went on the doctor, ignoring General Merton's rising color. "In the past, rain has been produced in several cases where conditions were right--that is, when the air held plenty of moisture which refused to fall--by the discharge from a plane of a cloud of positively charged dust particles. Ergo, a heavy negative charge in the air, which will absorb rather than discharge a positive charge, should tend to prevent rain from falling. I believe that a stream of negative particles is being liberated into the air near here, and allowed to drift where it will. That was my theory when I had the First Air Division equipped with those dust ejector tubes.

"I knew that if such a condition existed, the positively charged dust would be pulled down toward the source of the negative particle stream, which must, in many ways, resemble a cathode ray. That was why I wanted the behavior of the dust clouds watched and reported. What I did not foresee was that the iron and steel parts of the plane, acc.u.mulating a heavy negative charge, would be magnetized enough to slow down the motors and eventually wreck the ships."

"We have had eight ships wrecked unexplainably within twenty miles of here, all of them to the south, during the past year," said Colonel Wesley.

"It had slipped my notice. At any rate, the behavior of the ships this afternoon showed me that my theory is correct, and that some such device exists and is in active operation. Our next task is to locate it and destroy it."

"You shall have every man on the Proving Ground!" cried Colonel Wesley.

"Thank you. General Merton, will you detach three ships from the First Air Division by radio and have them report here? I want two pursuit ships and one bomber, with a rack of hundred-pound demolition bombs. All three must have duralumin cylinder blocks."

"I'll do it at once, Doctor," the general agreed.

"Thank you. Carnes, telephone Washington for me. Tell Dr. Burgess that I want Tracy, Fellows and Von Amburgh, with three more men down here by the next train. Also tell him to have Davis rig up a demagnetizer large enough to demagnetize the motors of a transport plane and bring it down here to fix up General Merton's ship. When you have finished that, get hold of Bolton and ask for a dozen secret service men. I want selected men with Haggerty in charge."

"All right, Doctor. Shall I tell Miss Andrews to come down as well?"

Dr. Bird frowned.
