time the bushes and irregular rocks disappeared, and he found himself on what could be nothing but a
badly kept road. He did not realize its condition at first; but within a few feet he found a rivulet flowing
across it, in a fairly deep gully which it had cut in the hard earth. Investigating this flow of water, he found
that its source was the shaftlike excavation, which was apparently full of water almost to the level of the
road. With growing enthusiasm, Thrykar found that the hole was fully a hundred and fifty yards in the
dimension running parallel to the face of the moun-tain; and he had learned during his descent that it had
fully half that measure in the other direction. If it were only deep enough—he was on the point of entering
the water to investigate, when he remembered the communicator, which might suffer damage if wet, and
from which he had promised Tes not to separate himself. Instead of investigating the pit, therefore, he
turned back, following the road toward the sounds which had first roused his curiosity.
His progress, on the legs which were so ridiculously short for his height, was not rapid. In fifteen
minutes he had passed two more of the water-filled pits and was approaching a third. This he was able to
examine in more detail than the others, though he could not approach it closely; for the road at this point,
and the water near it, were illuminated by the first of the town's outlying street lamps. A few yards farther,
on the side of the road away from the pits, house lights began to be visible; and, seeing them, Thrykar
paused to consider.
The sound was evidently coming from farther inside the town. If he went any further in his
investigations, he not only sacrificed the shelter of darkness, but could also expect a heavier concentration
of human beings. On the other hand, his skin was dark in color, the lights were by to means numerous, he
was very curious about the sounds which had continued without interruption since he had first heard them,
and it would be necessary to confront a human being eventually, in any case—though, if all went well, the
human being would never know it. Thrykar finally elected to proceed, with increased cau-tion.
He chose the side of the road away from the pits, as it was somewhat darker at first, and offered
some conceal-ment in the form of hedges and fences in front of the houses, which now began to be more
numerous. He walked, with his mincing gait, close beside these, standing at his full height and letting the
great, independent eyes set on either side of his neckless, rigidly set head rove constantly around the full
circle of his vision. One more pit was passed in this fashion; but a hundred yards further down the road,
on the right side, a wall began which effectually cut off the sight of any more, if they existed. It was a
fence of boards, solidly built, and its top was fully two feet above Thrykar's head. The sounds appeared
to be coming from a point behind this barrier, but somewhat further down the road.
Having come so far, the alien was human enough to dislike the idea of having wasted his efforts. He
crossed the road at a point midway between two street lamps. Between the pits, the brush-covered slope
of the hill came down almost to the thoroughfare; so he dropped flat once more to take advantage of this
cover as he approached the near end of the wall. He had hoped to find access to the hinder side of the
barrier, but he found that, instead of beginning where it was first visible, the portion along the road was
merely a continuation of a similar structure that came down the hillside; and Thrykar considered it a waste
of time to circumambulate the enclosure on the chance of finding an opening.
Instead, he rose once more to his full height, and looked carefully about him. The neighborhood still
seemed deserted. Pressing close against the boards, he reached up and let the tips of his four wiry
tentacles curl over the top of the fence. The appendages, even at the roots, were not much thicker than a
human thumb, for they were, anatomically, detached portions of the great side fins rather than legs and
feet modified for prehensile use; unless they could be wound completely around an object, they could not
approach the gripping or pulling strength of the human hand and arm. Thrykar, however, let his supple
body sag in an S-curve, and straightened suddenly, leaping upward; and at the same instant exerted all
the strength of which the slender limbs were capable. The effort proved sufficient to get the upper portion
of his body across the top of the fence, and during the few seconds he was able to maintain the position
he saw enough to satisfy him.
There were two more of the pits inside the fence, dimly lighted by electric bulbs. They contained
practically no water, and were enormously deep—the nearer, whose bottom was visible to Thrykar, was
over two hundred feet from the edge to the loose blocks of stone that lay about in the depths. The pits
were quarries, quite evidently. The stone blocks and tools, as well as the innumerable nearly flat faces on
