prune, they can plant. They have the education for which they are fitted. They are not versed in those extraordinary modifications which can be produced in plants by chemical changes caused artificially in the nature of the sap. That branch is naturally reserved for beings of the first class. They are taught how to weave and how to make the garments which we all wear. They are taught how to clean our houses in the quickest, most silent and most effective manner. Briefly, they do any work which their intelligence and judgment entitle them to do. Beyond that we do not go. We do not give them knowledge which would be dangerous to them and to us. When you return home, my friend, if ever you do return home, preach to your poor benighted people the inequality of man and the advisability of restricting all really important knowledge to the higher grade."

One day while we were chatting about indifferent subjects he mentioned quite casually that he had been cross-speaking the Central Office and that he found that MZ04 had died that morning.

"I am sorry to hear it," I said. "For after all he received me kindly—fed me and clothed me. When is the funeral?"

"Funeral?" said the Professor. "We have no funerals. The body of MZ04 went into the refuse-destructor hours ago. Death is a confession of failure, a sure proof of a blunder somewhere, and therefore ordinary politeness tells us that we should take as little notice of it as possible."

"Who will take his place?" I asked.

"That has already been decided by the Inner Office."

"You had no ambitions in that direction?"

"None whatever. There is no reason why in addition to my present appointment I should not now be holding a post—and a highly placed post—in the Inner Office. It is merely a want of appreciation and, I am afraid I must add, a certain meanness in the minds of some first-class beings which keeps me a humble professor. However, merit will tell; I can trust to that."

The boasted civilisation of Thule had at any rate not extirpated human vanity. The vanity of the Professor was colossal. No compliment was too gross for him to accept with avidity. His nature was indeed very curious and difficult for a simple man like myself to comprehend. In spite of the casual way in which he spoke of death, I was convinced that he lived in hourly dread of it. In spite of the fact that he spoke of every known form of religion as an idle superstition, and professed the most absolute materialism, I think he was unable to disbelieve entirely in the future life. His nerves were not good. Sometimes in the middle of the night he would tap at the door of the cupboard where I slept and ask me to come out and speak to him. There was always some excuse, and I think the excuse was never the true one. The fact of the case is that the extreme solitude in which most of these first-class beings lived had its inevitable effect upon them. They had, as the Professor observed, no entertainments. They had really no social gatherings. Occasionally one friend would pay a brief and formal visit to another friend, but there was nothing beyond that, When they went abroad for exercise or to bask in the sun, they as a rule passed one another unnoticed.

I was myself the reason why for a time the number of visitors to the Professor's house increased considerably. People came to see me, and he produced me and lectured upon me in terms which were sufficiently humiliating.

"Observe," he would say, "the ludicrous smallness of the head and the short and attenuated forelegs. In this respect one might almost believe him to be a second-class being. He is probably, however, a still lower type. The skin is whiter from deficient pigmentation, and the size of the body is smaller than in a second-class male. In the land from which he comes I find that they learn nothing by experience. The child born into the world there naturally adopts the safe quadrupedal position and has the use of its toes. The creature that we have here can do absolutely nothing with his toes and is uncomfortable in the quadrupedal position. In fact, the deformity of his body prevents him from adopting it easily."

At this point in his lecture he would change to a different language and continue. This second language was used by first-class beings among themselves when they wished to say anything without being understood by those whom they considered their inferiors. In the presence of a second-class being it was that language which the first class always adopted. Among themselves and in my presence they spoke English, except on the occasions when they did not wish me to understand them.

I began to rebel against the kind of life which I was leading. I disliked to be made a curiosity and a show of. The monotony affected me. The horrible familiarities of those two plants in my sleeping-room got on my nerves. I began to hint to the Professor that I must have change and more freedom or that the source of his information would possibly be dried up.

"If you became useless to me," he said carelessly, "you would be killed, of course. You would have failed and your body would go into the refuse-destructor."

"Very likely," I said. "But you would not get the information which you want. And you do want it, you know."

That was my trump card. He really did want to acquire all possible information about what he called the old world. In return for this I was always able to obtain concessions, and I did not fail in this case. I told him that I wished to explore the island, to go right over to the other side of it and see the places where the second class lived and the work they did. At first he tried to dissuade me. He pointed out that the distance to the other side of the island was not less than eight miles, and refused to believe that this would not be beyond my strength. He painted in lurid colours the dangers of the mountain which I should have to cross and of the forests which I should find on the other side. I, however, remained obstinate in my purposes and at last obtained his permission to go, on condition that I returned in ten days and that I never spoke with any second-class being whom I might encounter, lest I should inadvertently betray important knowledge to them. This promise I gave readily enough, but, I must confess, with no intention of keeping it. He gave me some further instructions and a pass written with the ink pencil, which he said would entitle me to protection and help from any first-class being whom I might encounter.

Thus then on a fine sunny morning I started out with no more equipment than I could easily carry on my back. The prospect of adventure lured me. For the first time for days I felt in good temper and spirits.

CHAPTER VI

The Professor had been well within the mark in stating that the breadth of the island was not less than eight miles. By sundown I must have covered thirty miles at least and encamped for the night by the side of a swift and narrow stream. I had still the low hill to cross which the Professor had spoken of as a mountain. In a flat country such as Thule, all hills are mountains.

The Professor's mistakes in regard to time and distance interested me a good deal. I could understand that they rendered him professionally unsuitable for the practical work of the Central Office and that they probably helped to debar him from the post which he desired in the Inner Office. It may be, perhaps, that one cannot have an over-development in one direction without a compensating defect in another. The Professor showed the same anxiety to conceal his want of time-sense that an engine-driver might show to conceal his colour-blindness. After all, instances of this want of time-appreciation are common enough among my own people in dealing with the past. One knows the vagueness with which the ordinary man assigns a fact to the sixteenth or seventeenth century—a fact which in reality belongs to the eighteenth. The further back we go the more vague we become. It is difficult for us to realise
