how the dignified, matronly bearing seemed to contrast with the springy tread and youthful lissomness of movement.
As he turned away to re-enter the house he saw the postman approaching; but as he was not expecting any letters, and his mind was still occupied with his late visitor, he did not wait. Nor when, a minute later, he heard the characteristic knock, did he return to inspect the letter-box; which was, just as well in the circumstances. Instead, he made his way out by the back door into the large kitchen garden and orchard and followed the long, central path which brought him at length to a high red brick wall, in which was a door furnished with a knocker and flanked by an electric bell. This he opened with a latchkey of the Yale pattern, and, having passed through, carefully shut it behind him.
He was now in what had probably been originally the orchard and kitchen garden of the old house in which he lived, but which had since been converted into a flower garden, though many of the old fruit trees still remained. It was a large oblong space, more than a quarter of an acre in extent, and enclosed on all sides by a massive old wall nearly seven feet high, in which were only two openings: the door by which he had just entered and another door at one side, also fitted with a Yale lock and guarded, in addition, by two bolts.
It was a pleasant place if quiet and seclusion were the chief desire of the occupant—as they apparently were, to judge by Mr. Pottermack’s arrangements. The central space was occupied by a large, smooth grass plot, surrounded by well-made paths, between which and the wall were wide flower borders. In one corner was a brick-built summer-house; quite a commodious affair, with a good tiled roof, a boarded floor, and space enough inside for a couple of armchairs and a fair-sized table. Against the wall opposite to the summer-house was a long shed or outhouse with glass lights in the roof, evidently a recently built structure and just a little unsightly—but that would be remedied when the yew hedge that had been planted before it grew high enough to screen it from view. This was the workshop, or rather a range of workshops; for Mr. Pottermack was a man of many occupations, and, being also a tidy, methodical man, he liked to keep the premises appertaining to those occupations separate.
On the present occasion he made his way to the end compartment, in which were kept the gardening tools and appliances, and having provided himself with a spade, a mallet, a long length of cord, and a half-dozen pointed stakes, walked out to the grass plot and looked about him. He was quite clear in his mind as to where the sun-dial was to stand, but it was necessary to fix the spot with precision. Hence the stakes and the measuring-line, which came into use when he had paced out the distances approximately and enabled him, at length, to drive a stake into the ground and thereby mark the exact spot which would be occupied by the centre of the dial.
From this centre, with the aid of the cord, he drew a circle some four yards in diameter and began at once to take up the turf, rolling it up tidily and setting it apart ready for relaying. And now he came to the real job. He had to dig right down to the subsoil. Well, how far down was that? He took off his coat, and, grasping the spade with a resolute air, gave a vigorous drive into the soil at the edge of the circle. That carried him through the garden mould down into a fine, yellowish, sandy loam, a small quantity of which came up on the spade. He noted its appearance with some interest but went on digging, opening up a shallow trench round the circumference of the circle.
By the time that he had made a second complete circuit and carried his trench to a depth of some eight inches, the circle was surrounded by a ring of the yellow loam, surprisingly bulky in proportion to the shallow cavity from which it had been derived. And once more his attention was attracted by its appearance. For Mr. Pottermack amongst his various occupations included occasionally that of sand-casting. Hitherto he had been in the habit of buying his casting-sand by the bag. But this loam, judging by the sharp impressions of his feet where he had trodden in it, was a perfect casting-sand, and to be had for the taking at his very door. By way of testing its cohesiveness, he took up a large handful and squeezed it tightly. When he opened his hand the mass remained hard and firm and showed the impressions of his fingers perfectly to the very creases of the skin.
Very pleased with his discovery, and resolving to secure a supply of the loam for his workshop, he resumed his digging, and presently came down to a stratum where the loam was quite dense and solid and came up on the spade in definite coherent lumps like pieces of a soft rock. This, he decided, was the true subsoil and was as deep as he need go; and having decided this, he proceeded to dig out the ret of the circle to the same depth.
The work was hard and, after a time, extremely monotonous. Still Mr. Pottermack laboured steadily with no tendency to slacking. But the monotony exhausted his attention, and while he worked on mechanically with unabated vigour his thoughts wandered away from his task; now in the direction of the sun-dial, and now—at, perhaps, rather more length—in that of his pretty neighbour and her spoils, which were still awaiting his attentions in the tin box.
He was getting near the centre of the circle when his spade cut through and brought up a piece of spongy, fungus-eaten wood. He glanced at it absently, and having flung it outside the circle, entered his spade at the same spot and gave a vigorous drive. As the spade met with more than usual resistance, he threw a little extra weight on it. And then, suddenly, the resistance gave way; the spade drove through, apparently into vacant space. Mr. Pottermack uttered a startled cry, and after an instant’s precarious balancing saved himself by a hair’s breadth from going through after it.
For a moment he was quite shaken—and no wonder. He had staggered back a pace or two and now stood, still grasping the spade, and gazing with horror at the black, yawning hole that had so nearly swallowed him up. But as, after all, it had not, he presently pulled himself together and began cautiously to investigate. A very little tentative probing with the spade made everything clear. The hole which he had uncovered was the mouth of an old well: one of those pernicious wells which have no protective coping but of which the opening, flush with the surface of the ground, is ordinarily closed by a hinged flap. The rotten timber that he had struck was part of this flap, and he could now see the rusty remains of the hinges. When the well had gone out of use, some one, with incredible folly, had simply covered it up by heaping earth on the closed flap.
Mr. Pottermack, having made these observations, proceeded methodically to clear away the soil until the entire mouth of the well was exposed. Then, going down on hands and knees, he approached, and cautiously advancing his head over the edge, peered down into the dark cavity. It was not quite dark, however, for though the slimy brick cylinder faded after a few feet into profound gloom, Mr. Pottermack could see, far down, as it seemed in the very bowels of the earth, a little circular spot of light on which was the dark silhouette of a tiny head. He picked up a pebble, and, holding it at the centre of the opening, let it drop. After a brief interval the bright spot grew suddenly dim and the little head vanished: and after another brief interval there came up to his ear a hollow “plop” followed by a faint, sepulchral splash.
There was, then, water in the well; not that it mattered to him, as he was going to cover it up again. But he was a man with a healthy curiosity and he felt that he would like to know all about this well before he once more consigned it to oblivion. Walking across to the workshop, he entered the metalwork section and cast his eye around for a suitable sinker. Presently, in the “oddments” drawer, he found a big iron clock-weight. It was heavier than was necessary, but he took it in default of anything more suitable, and going back to the well, he tied it to one end of the measuring-cord. The latter, being already marked in fathoms by means of a series of knots, required no further preparation. Lying full-length by the brink of the well, Mr. Pottermack dropped the weight over and let the cord slip through his hands, counting the knots as it ran out and moving it up and down as the weight neared the water.
The hollow splash for which he was listening came to his ear when the hand that grasped the cord was between the fourth and fifth knots. The depth, therefore, of the well to the surface of the water was about twenty-seven feet. He made a mental note of the number and then let the cord slip more rapidly through his hands. It was just after the seventh knot had passed that the
