"Yes, I am agreeable," said Stanton nervously and hastily. "If there are things in it with which we can compromise, I would suggest that we do not offend them."

"I am, then, empowered to act for all of you," said Fragoni, ignoring the suggestion of Stanton.

He rose from his chair and walked out on the terrace. The others followed after him.

Looking westward, they saw the mammoth craft descending slowly in their direction.

Its vast dimensions became more and more apparent as, spellbound, they watched it approach closer and closer to them.

The thing in the sky was now not more than three thousand feet above them and only a few miles to the westward.

The observers on the terrace regarded it for a moment in silence as it drifted forward and downward.

"It's colossal!" Steinholt then exclaimed, lost in scientific admiration of the mammoth craft. "Magnificent! Superb!"

"But it's coming right toward us!" cried Stanton.

"What makes it move, I wonder?" asked Dirk. "And how in the world is it controlled?"

"It surely is not of this world," said Fragoni quietly. "That gigantic thing has come to us from somewhere out of the infinite and terrible depths of s.p.a.ce."

Another minute elapsed while they watched it, speechless with wonder.

"Do you know," Lazarre then said calmly, "I believe that it is going to land in the waters of the Sound. It appears so to me, anyway."

It was nearly opposite them by this time, and not more than a thousand feet above the water. A few planes which, very apparently, were being flown by intrepid and fearless flyers, were hovering close around it.

Then finally it came to rest, as Lazarre had predicted, in the water some two miles off sh.o.r.e, and it was obscured by a great cloud of vapor for several minutes.

"Steam," a.s.serted Steinholt. "That trip around the world, which it made in a few minutes, generated considerable frictional heat in the sh.e.l.l."

"Come," said Fragoni, "we'll fly out and look the thing over."

Around the corner of the building, on the level of the terrace, there was a landing stage which was occupied by a number of planes of various sizes.

Dirk entered the door of a small twenty pa.s.senger speedster, and the others filed in after him.

"Ready?" he asked, after he had seated himself at the controls.

"Ready!" replied Fragoni.

The plane rose straight up into the air and then darted gracefully out over the Sound.

Dirk swooped straight down at the leviathan which lay so quietly on the surface of the Sound and then slowly circled around it. No sign of an aperture of any sort could be seen in the craft. Then he dropped the plane lightly on the water, close to the metallic monster, which towered fully four hundred feet above them, despite the fact that more than half of it was submerged.

"It must be hollow," remarked Steinholt, "or it wouldn't be so far out of the water. In fact, it most certainly would sink, if it was solid."

At the touch of a lever which lay under one of Dirk's hands the plane rose straight out of the water, and he maneuvered it directly over the top of the strange enigma. Then he touched a b.u.t.ton and the pontoons were drawn up into the undercarriage of the craft.

"Shall I make a landing on it?" he asked, turning his head and addressing Fragoni.

The latter nodded his head, and Dirk dropped the ship gently onto the smooth surface of the monster, the pneumatic gearing completely absorbing the shock of the landing.

Dirk relinquished the controls and, opening the door of the cabin, he stepped out onto the rough and pitted substance of which the leviathan was compounded. He stood there while the others came out after him.

A large area on the top of the monster was perfectly flat and, within a very few moments, Dirk discovered that it was decidedly warm. He had brought the plane down close to the middle of the length of the strange craft in the belief that there, if anywhere, some indication of an entrance might be found.

The voice of Steinholt, tense with suppressed excitement, appraised him that his surmise had been correct.

"There is a manhole of some sort," the electrical wizard exclaimed. "And look, it is turning!"

They saw, not far ahead of them, a circular twelve-foot section of the deck slowly revolving, and, even as they watched, it commenced to rise slowly upward as the threads with which it was provided turned gradually around.

Almost involuntarily they retreated a few feet and stood there, spellbound, as they stared at the ma.s.sive, revolving section of the deck.

It continued to turn until fully ten feet of the mobile cylinder had been exposed. Then the bottom of it appeared. Even then it continued to revolve and rise on a comparatively small shaft which supported it and, at the same time, thrust it upward. Dirk and his companions kept their eyes on the rim of the well which had been exposed, and awaited the appearance of something, they knew not what. When the top of the great cylinder was fully twelve feet above the deck of the craft it slowly ceased to revolve.

Moment succeeded moment as the members of the little group rigidly and almost breathlessly awaited developments.

Then Dirk, with an impatient e.j.a.c.u.l.a.t.i.o.n, stepped forward toward the yawning hole and cautiously peered over the edge of it.

He stood there for a moment, as if transfixed, and then, with an exclamation of horror, retreated swiftly to where his friends were standing.

"What is it?" gasped Steinholt. "What did you see when--"

But the words died on his lips for, swarming swiftly over every side of the well, there poured an array of erect, piercing-eyed beings, who had all the characteristics of humans. They were clad in tight-fitting attire of thin and pliant metal which, with the exception of their faces, shielded them from head to foot. On their heads they wore close-fitting helmets, apparently equipped with visors which could be drawn down to cover their unprepossessing features.

Each one of them carried a tube which bore a striking resemblance to a portable electric flashlight.

Swiftly they advanced, in ranks of eight, toward Dirk and his companions who, gripped with amazement, held their positions.

The first line came to a halt not more than four feet from the little group on the deck. The other lines halted, too, and formed a great platoon. Then a shrill whistle sounded and the formation parted in the middle, leaving an open path that led backward to the entrance, to the well.

A moment later the watchers saw the regal figure of a man emerge from the orifice and, after a moment's pause, advance slowly in their direction with a stately stride.

He was tall and muscular and blond and his attire, golden in texture, glittered with sparkling gems.

As he approached them he raised his right hand and, inasmuch as his countenance was calm and benign, his gesture appeared to be one of peace and good-will.
