but hysterical struggle that came from Lady Stella's retreat. The girl who had remained with her had displayed a quite feminine interest in her equipment and had come upon a particularly charming and diaphanous sleeping suit. For some obscure reason this secret daintiness amused the young Utopian extremely, and it was with some difficulty that Lady Stella restrained her from putting the garment on and dancing out in it for a public display. "Then you put it on," the girl insisted.
"But you don't understand," cried Lady Stella. "It's almost--sacred! It's for nobody to see--ever."
"But why?" the Utopian asked, puzzled beyond measure.
Lady Stella found an answer impossible.
The light meal that followed was by terrestrial standards an entirely satisfactory one. The anxiety of Mr. Freddy Mush was completely allayed: there were cold chicken and ham and a very pleasant meat pate. There were also rather coarse-grained but most palatable bread, pure butter, an exquisite salad, fruit, cheese of the Gruyere type, and a light white wine which won from Mr. Burleigh the tribute that "Moselle never did anything better."
"You find our food very like your own?" asked the woman in the red-trimmed robe.
"Eckquithit quality," said Mr. Mush with his mouth rather full.
"Food has changed very little in the last three thousand years. People had found out all the best things to eat long before the Last Age of Confusion."
"It's too real to be real," Mr. Barnstaple repeated to himself. "Too real to be real."
He looked at his companions, elated, interested and eating with appreciation.
If it wasn't for the absurdity of these Utopians speaking English with a clearness that tapped like a hammer inside his head Mr. Barnstaple would have had no doubt whatever of its reality.
No servants waited at the clothless stone table; the woman in the white and scarlet robe and the two aviators shared the meal and the guests attended to each other's requirements. Mr. Burleigh's chauffeur was for modestly shrinking to another table until the great statesman reassured him with: "Sit down there, Penk. Next to Mr. Mush." Other Utopians with friendly but keenly observant eyes upon the Earthlings came into the great pillared veranda in which the meal had been set, and smiled and stood about or sat down. There were no introductions and few social formalities.
"All this is most reassuring," said Mr. Burleigh. "Most reassuring. I'm bound to say these beat the Chatsworth peaches. Is that cream, my dear Rupert, in the little brown jar in front of you?... I guessed as much. If you are sure you can spare it, Rupert.... Thank you."

Several of the Utopians made themselves known by name to the Earthlings. All their voices sounded singularly alike to Mr. Barnstaple and the words were as clear as print. The brown-eyed woman's name was Lychnis. A man with a beard who might perhaps, Mr. Barnstaple thought, have been as old as forty, was either Urthred or Adam or Edom, the name for all its sharpness of enunciation had been very difficult to catch. It was as if large print hesitated. Urthred conveyed that he was an ethnologist and historian and that he desired to learn all that he possibly could about the ways of our world. He impressed Mr. Barnstaple as having the easy carriage of some earthly financier or great newspaper proprietor rather than the diffidence natural in our own every-day world to a merely learned man. Another of their hosts, Serpentine, was also, Mr. Barnstaple learnt with surprise, for his bearing too was almost masterful, a scientific man. He called himself something that Mr. Barnstaple could not catch. First it sounded like "atomic mechanician," and then oddly enough it sounded like "molecular chemist." And then Mr. Barnstaple heard Mr. Burleigh say to Mr. Mush, "He said 'physio-chemist,' didn't he?"
"I thought he just called himself a materialist," said Mr. Mush.
"I thought he said he weighed things," said Lady Stella.
"Their intonation is peculiar," said Mr. Burleigh. "Sometimes they are almost too loud for comfort and then there is a kind of gap in the sounds."...
When the meal was at an end the whole party removed to another little building that was evidently planned for classes and discussions. It had a semicircular apse round which ran a series of white tablets which evidently functioned at times as a lecturer's blackboard, since there were black and coloured pencils and cloths for erasure lying on a marble ledge at a convenient height below the tablets. The lecturer could walk from point to point of this semicircle as he talked. Lychnis, Urthred, Serpentine and the Earthlings seated themselves on a semicircular bench below this lecturer's track, and there was accommodation for about eighty or a hundred people upon the seats before them. All these were occupied, and beyond stood a number of graceful groups against a background of rhododendron-like bushes, between which Mr. Barnstaple caught glimpses of grassy vistas leading down to the shining waters of the lake.
They were going to talk over this extraordinary irruption into their world. Could anything be more reasonable than to talk it over? Could anything be more fantastically impossible?
"Odd that there are no swallows," said Mr. Mush suddenly in Mr. Barnstaple's ear. "I wonder why there are no swallows."
Mr. Barnstaple's attention went to the empty sky. "No gnats nor flies perhaps," he suggested. It was odd that he had not missed the swallows before.
"Sssh!" said Lady Stella. "He's beginning."
III
This incredible conference began. It was opened by the man named Serpentine, and he stood before his audience and seemed to make a speech. His lips moved, his hands assisted his statements; his expression followed his utterance. And yet Mr. Barnstaple had the most subtle and indefensible doubt whether indeed Serpentine was speaking. There was something odd about the whole thing. Sometimes the thing said sounded with a peculiar resonance in his head; sometimes it was indistinct and elusive like an object seen through troubled waters; sometimes though Serpentine still moved his fine hands and looked towards his hearers, there were gaps of absolute silence--as if for brief intervals Mr. Barnstaple had gone deaf.... Yet it was a discourse; it held together and it held Mr. Barnstaple's attention.
Serpentine had the manner of one who is taking great pains to be as simple as possible with a rather intricate question. He spoke, as it were, in propositions with a pause between each. "It had long been known," he began, "that the possible number of dimensions, like the possible number of anything else that could be enumerated, was unlimited!"
Yes, Mr. Barnstaple had got that, but it proved too much for Mr. Freddy Mush.
"Oh, Lord!" he said. "Dimensions!" and dropped his eye-glass and became despondently inattentive.
"For most practical purposes," Serpentine continued, "the particular universe, the particular system of events, in which we found ourselves and of which we formed part, could be regarded as occurring in a space of three rectilinear dimensions and as undergoing translation, which translation was in fact duration, through a fourth dimension, time. Such a system of events was necessarily a gravitational system."
"Er!" said Mr. Burleigh sharply. "Excuse me! I don't see that."
So he, at any rate, was following it too.
"Any universe that endures must necessarily gravitate," Serpentine repeated, as if he were asserting some self-evident fact.
"For the life of me I can't see that," said Mr. Burleigh after a moment's reflection.
Serpentine considered him for a moment. "It is so," he said, and went on with his discourse. Our minds, he continued, had been evolved in the form of this practical conception of things, they accepted it as true, and it was only by great efforts of sustained analysis that we were able to realize that this universe in which we lived not only extended but was, as it were, slightly bent and contorted, into a number of other long unsuspected spatial dimensions. It extended beyond its three chief spatial dimensions into these others just as a thin sheet of paper, which is practically two dimensional, extended not only by virtue of its thickness but
