to that particular state of dampness that the professional moulder seeks to produce with his watering-pot.
However, interesting as the prints were to the mechanic’s eye, the sooner they were got rid of the better. Thus reflecting, Pottermack strode away towards the workshop in quest of a rake and a besom; and he was, in fact, reaching out to grasp the handle of the door when he stopped dead and stood for some seconds rigid and still with outstretched arm and dropped jaw. For in that moment a thought which had, no doubt, been stirring in his subconscious mind had come to the surface, and for the first time the chill of real terror came over him. Suddenly he realized that he had no monopoly of this remarkable loam. It was the soil of the neighbourhood—and incidentally of the little lane that led from the town and passed along beside his wall. In that lane there must be a single track of footprints—big, staring footprints, and every one of them as good as a signature of James Lewson—leading from the town and stopping at his gate!
After a few moments of horror-stricken reflection he darted into the tool-house and brought out a short ladder. His first impulse had been to open the gate and peer out, but an instant’s reflection had shown him the folly of exposing himself to the risk of being seen—especially at the very gate to which the tracks led. He now carried the ladder across to an old pear tree which thrust its branches over the wall, and, planting it silently where the foliage was densest, crept softly up and listened awhile. As no sound of footsteps was audible, and as the moon had for the moment retired behind the bank of cloud, he cautiously advanced his head over the wall and looked down into the lane. It was too dark to see far in either direction, but apparently there was no one about; and as the country quiet was unbroken by any sound, he ventured to crane farther forward to inspect the path below.
The light was very dim; but even so he could make out faintly a single track of footprints—large footprints, widely spaced, the footprints of a tall man. But even as he was peering down at them through the darkness, trying to distinguish in the vaguely seen shapes some recognizable features, the moon burst forth again and the light became almost as that of broad day. Instantly the half-seen shapes started up with a horrid distinctness that made him catch his breath. There was the preposterous prancing horse with the legend “Invicta,” there was the makers’ name, actually legible from the height of the wall, and there were the circular heels with their raised central stars and the very screws clearly visible even to their slots!
Pottermack was profoundly alarmed. But he was not a panicky man. There, in those footprints, was evidence enough to hang him. But he was not hanged yet; and he did not mean to be, if the unpleasantness could be avoided. Perched on the ladder, with his eyes riveted on the tracks of the man who had come to “squeeze” him, he reviewed the situation with cool concentration, and considered the best way to deal with it.
The obvious thing was to go out and trample on those footprints until they were quite obliterated. But to this plan there were several objections. In the first place, those enormous impressions would take a deal of trampling out. Walking over them once would be quite useless, for his own feet were comparatively small, and even a fragment of one of Lewson’s footprints would be easily recognizable. Moreover, the trampling process would involve the leaving of his own footprints in evidence; which might be disastrous if it should happen—as it easily might—that Lewson had been seen starting along the footpath. For this path, unfrequented as it was, turned off from the main road at the outskirts of the town where wayfarers were numerous enough. The reason that it was unfrequented was that it led only to a wood and a stretch of heath which were more easily approached by a by-road. Finally, he himself might quite possibly be seen performing the trampling operations, and that would never do. In short, the trampling scheme was not practicable at all.
But what alternative was there? Something must be done. Very soon the man would be missed and there would be a search for him; and as things stood there was a set of tracks ready to guide the searchers from the town to his—Pottermack’s—very gate. And inside the gate was the open well. Clearly, something must be done, and done at once. But what?
As he asked himself this question again and again he was half-consciously noting the conditions. Hitherto, no one had seen Lewson’s footprints at this part of the path. That was evident from the fact that there were no other fresh footprints—none that trod on Lewson’s. Then, in half an hour at the most, the shadow of the wall would be thrown over the path and the tracks would then be quite inconspicuous. And, again, it was now past nine o’clock and his neighbours were early folk. It was extremely unlikely that any one would pass along that path until the morning. So there was still time. But time for what?
One excellent plan occurred to him, but, alas! he had not the means to carry it out. If only he had possession of Lewson’s shoes he could put them on, slip out at the gate and continue the tracks to some distant spot well out of his neighbourhood. That would be a perfect solution of the problem. But Lewson’s shoes had vanished for ever from human ken—at least, he hoped they had. So that plan was impracticable.
And yet, was it? As he put the question to himself his whole demeanour changed. He stood up on his perch with a new eagerness in his face; the eagerness of a man who has struck a brilliant idea. For that was what he had done. This excellent plan, which yielded the perfect solution, was practicable after all. Lewson’s shoes were indeed beyond his reach. But he had a fine assortment of Lewson’s footprints. Now footprints are made by the soles of shoes. That is the normal process. But by the exercise of a little ingenuity the process could be reversed; shoe-soles could be made from footprints.
He descended the ladder, thinking hard; and as the cloud once more closed over the moon, he fetched the hurdle and placed it carefully over the mouth of the well. Then he walked slowly towards the workshop—avoiding the now invaluable footprints—shaping his plan as he went.
CHAPTER III
MR. POTTERMACK GOES A-SUGARING
The efficient workman saves a vast amount of time by so planning out his job in advance that intervals of waiting are eliminated. Now Mr. Pottermack was an eminently methodical man and he was very sensible that, in the existing circumstances, time was precious. Accordingly, although his plan was but roughly sketched out in his mind, he proceeded forthwith to execute that part of it which could be clearly visualized, filling in the further details mentally as he worked.
The first thing to be done was, obviously, to convert the perishable, ephemeral footprints, which a light shower would destroy, into solid, durable models. To this end, he fetched from the workshop the tin of fine plaster of Paris which he kept for making small or delicate moulds. By the aid of his little lamp he selected a specially deep and perfect impression of Lewson’s right foot, and into this he lightly dusted the fine powder, continuing the process until the surface was covered with an even layer of about half an inch thick. This he pressed down very gently with the flat end of the lamp, and then went in search of a suitable impression of the left foot, which he treated in like manner. He next selected a second pair of prints, but instead of dusting the dry plaster into them he merely dropped into each a pinch to serve as a mark for identifying it. His reason for thus varying the method was that he was doubtful whether it was possible to pour liquid plaster into a loam mould (for that was what the footprint actually was) without disturbing the surface and injuring the pattern.
Returning to the workshop, he mixed a good-sized bowl of plaster, stirring and beating the creamy liquid with a large spoon. Still stirring, he carried it out, and, going first to the prints which contained the dry plaster, he carefully ladled into them with the spoon small quantities of the liquid plaster until they were well filled. By this time the liquid was growing appreciably thicker and more suitable for the unprotected prints, to which he accordingly hastened, and proceeded quickly, but with extreme care, to fill them until the now rapidly thickening plaster was well heaped up above the surface.
He had now at least, a quarter of an hour to wait while the plaster was setting, but this he occupied in cleaning out
