Recovering myself, I turned my attention to the workers at the seed beds. The men engaged at the first bed went slowly along the walks taking every now and then something out of the boxes which were slung one over the shoulder of each, and planting it in the ground and covering it over. I saw that they examined also something already planted, and sometimes took it up and put it into the box. I could not tell, [185] ]owing to the distance and the motion, whether or not what they took up exhibited any visible growth. The substances, whatever they were, which were thus taken up, were placed in a little waggon which ran at the eastern end of the bed at right angles to the walks, and conveyed its contents to the walks which separated the first bed from the second, and were dealt with by the workers there. If you ask me how I knew that it was the substances exhumed and not the substances in the parcels that were thus passed, I can only say that such was my conclusion from the whole aspect of the movement, for I could not accurately distinguish small objects at the distance.
The way of working at the next four beds was not so different from what I have described, as to make it worth while attempting a detailed account. It will suffice to say that the mode of procedure was to sow something in each bed, and to take up something which had been down in order to transfer it to the next bed, and this latter process evidently involved much careful examination and discrimination. I should also mention that at the third bed and onward the workers wore masks, apparently wire masks of some elaborate construction. They wore them, not continuously, but whenever they stooped to the ground or examined very [186] ]closely the substances with which they were dealing. At other times the masks hung at the girdles. At the fourth bed the workers wore the masks more frequently, and at the fifth they only removed them occasionally. The way of working at the sixth bed was different and will need a fuller description.
But before attempting to describe it I should say that just as I was beginning to observe the sixth bed, a slight change came in the weather which made two considerable changes, each in a different direction, in my opportunities of observation. It had been quite calm and at the same time cloudy. Now a light breeze began to blow and the sun shone out. The effect of the breeze was, at first, so to increase the motion of the car as to make very close observation impossible. But Signor Davelli presently applied a sort of ballasting machinery, which had the effect of greatly steadying the car. I was so much interested in what was going on below that I did not very accurately observe how this was done. But I think that it was somehow in this way. He moved, by mechanical contrivance, certain weights in the car, so as to change the centre of gravity in such manner as to render the part of it which we occupied subject to less motion than the rest. I have not much skill in such matters and I hardly [187] ]know if this is possible, but so it seemed to me. But even after this was done the car was not by any means as steady as before.
At the same time, however, the sunshine which now appeared disclosed some features of the scene which I should otherwise have missed. For now, at the northern end of the beds, on a platform at right angles with the western platform, I saw several shadows which indicated to my now skilled eyesight the presence of several of the invisible cars. They were standing all still when I first saw them, but presently one moved, rose quickly from the earth, and passed gradually out of sight to the northward. I followed its course with my glass for several minutes, till it was nearly out of sight. I then turned again to the seed-beds. The men at the sixth bed were very few, only five in all, and each was working apparently on his own account. But they were all doing exactly the same kind of work. They were, as I thought, making a final selection of the germs which had undergone so careful a process of cultivation. Each of them had three boxes, instead of one, slung in front of him, and a long instrument in his hand with which he extracted certain substances from the ground. This instrument was constructed so as to hold in a little receptacle [188] ]what was lifted from the ground. Each of the workers, also, had slung over his shoulder what looked like a small frame. I selected one of the five at random, and watched his proceedings more particularly. Now and then he would unsling the frame and place it on the ground. Then he would give it a little twist, whereupon it would assume a form very like that of a lady’s work-table. I saw him do this many times, and each time he took something out of the closed receptacle which I have just mentioned, and placed it on the table, and observed it carefully with some kind of instrument that might have been a kind of microscope. After a more or less minute observation each time, he placed the substance observed in one of the boxes at his girdle, which he opened each time and carefully closed again. By-and-by he seemed to discover some substance which challenged his attention specially, for after a longer observation than usual, he took another instrument from his girdle and observed it more carefully and for a longer time. Then I could see that he called his neighbour, for he looked, and I almost thought that I could see his lips moving, and immediately the other looked up and came towards him. Then the first man handed his observing instrument to the second, who examined very carefully the substance [189] ]on the little table. Some discussion seemed to follow, an animated conversation as I thought, with certainly a rapid pantomimic accompaniment.
Then a very strange thing happened. As the first man stooped towards the table his mask fell off. My glass was so good that I saw it quite plainly come loose at one side, and I saw the man’s hand lifted up to catch it. But before he could reach it, it fell off as I have said. Then in a moment the man’s body became a mass of rapidly seething fluid, and the fluid became a dark cloud of smoke, which spread into the air and disappeared. Just so I had seen Signor Davelli’s body transformed and disappear the day before. The second man at once caught up the mask and stood apparently waiting. Presently a diffused vapour appeared. This became denser and denser, until it assumed the appearance of a seething fluid, as before. This quickly became consolidated and assumed the form of a body, the body of the man who had just disappeared. Then the other man, who was standing ready with the mask in his hand, fitted it again upon the first man, and both men proceeded to examine the substance before them, and to converse, as if nothing had happened to interrupt them. All this time (which, however, was a very short time, although the change [190] ]was by no means instantaneous, as the like change seemed to be yesterday) the other men worked away without, as far as I could see, taking any notice whatever of what was going on.
I exclaimed slightly and started, and this attracted Signor Davelli’s attention. He had been, I think, examining and preparing some instruments. “What do you see?” he said. I answered without taking my eyes from the glass. “A man over there disappeared and appeared again just as you did yesterday.”
“Careless wretches!” he said, looking towards the place that I was observing.
“I suppose,” I said, “that these substances which they are examining must be very deadly, for his mask fell off just before he disappeared, and I remember you said yesterday that what would kill us only drove you back into space.”
“And you infer, I suppose, that if you had been in his place you would have dropped down dead.”
“That is what I think,” said I.
