Tensed almost to the snapping point, each of the ten men stared about them in search of the horrible creatures Mortenson had told Steckel existed there. Suddenly they discovered that they were actually standing in swaying lush that reached to their shoulders. This came upon them as their eyes began to observe their immediate vicinity. The sudden change of environment had caused them a mild far-sightedness, but now they could see clearly on every side. The lush rolled and swayed like a sea of earthly wheat-stalks in a light breeze.
Mortenson realized in a moment that they would have to mark the spot or their inevitable wanderings would cause them to become hopelessly lost. He yanked his kerchief from a pocket and tied it like a flag to a tuft of the taller plants. It waved feebly in a cool breeze. He turned to Chief Steckel.
"I think it best that we string out in a line, Steckel," he said, his voice sounding microscopically low. "We ought to come upon the phantom bandit's trail in this vicinity. But be careful! He must be desperate and will shoot on sight."
Steckel gave his curt orders. The officers stretched out in a long line. The chief and Mortenson went forward side-by-side with Barton and Riley flanking them. The line swung gradually in a circle around the scientist's handkerchief which acted as a centre. The lush seemed unbroken, being so closely grown together that even a small animal would have left visible indications of its passing through it. They continued onward until suddenly the officers at the far end of the line emitted a triumphant yell. Immediately the others surrounded him to find the lush broken in a narrow path through which the desperado had gone. Feet had trampled down one spot. The trail led away from it. The trampled lush in the one place gave them the impression that the man had popped up out of the yielding soil to go marching away.
Barton suddenly stooped over to pick up an object. He handed it to Chief Steckel. It was a black-tipped matchstick.
"We're on his trail, chief," he said excitedly. "He lit a smoke here and tossed the match at his feet!"
Steckel gave a sibilant whistle. "Damned if we haven't traced the snake to his hole!" he snapped. "I hadn't much stock in this scheme, but it looks like his trail, all right. Let's follow it, strung out. He might be hiding in the grass and a line will bring him out."
He started forward rapidly, eagerly. Mortenson grasped his arm.
"Not so fast, Steckel," he warned ominously. "We're not in our own world, but in one unknown. This tall lush might harbor anything. I have no stomach for running into a wandering band of Fifth Dimensional beings."
Steckel fell back instantly. With Mortenson beside him he followed the trail, the others strung out on either side. Slowly they went on for what seemed hours. It was hard work for them to go through the lush. It was as tough and fibrous as dried coconut husks. Had it not been for their heavy clothing they would have been cut to shreds in no time. Their hands suffered from the ordeal, but it could not be helped. They had not prepared for such conditions and it was too late to go back. They were at last on the trail of the phantom killer. Only death or inconceivable terror could drive them from it. The man must be apprehended at any cost and each had secretly resolved to see the thing through to a finish. Yet they derived a certain sense of pride from the fact that they were among the first humans ever to tread this strange, blue-tinted world. Police history would long remember them for their daring.
