“We shall change later,” said Sir John, “and I shall be glad to get out of these stuffy and dirty garments. All the same I don’t fancy myself a cross between an imitation gladiator and a stained glass twelfth century saint.”

They thoroughly enjoyed their meal; eggs served in a wonderful salad of fruit and vegetables proved to be the staple part, and this course was followed by a baked grain, similar to barley, but of a bright green colour, deliciously creamy and sweet. There was milk to drink, and plenty of heavy cream.

“They seem to be almost vegetarians here,” said Mavis, “for although we have had plenty of milk, eggs and cream, I have not seen a sign of fish or meat.”

“All the better,” said Sir John, “after all that tinned stuff while we were on the Argenta—ugh!”

They drove in state to the students’ party. The Waz had constituted himself their guide, and they were very thankful for his services. The large ground floor of the Observatory had been converted into a veritable bower of roses. At one end, almost hidden by flowers, were the musicians—playing dreamy music on soft-toned, stringed instruments.

The Host in Chief, Kulmervan, with Waiko, stood on a raised dais at one end and received their guests, who were all announced by an usher who wore a kilt-like shirt and a flowing cape. As the strangers entered he announced from a card they gave him, first in his own language and then in English, “Sir John, Alan, Desmond, Masters, and Mavis.” No surnames were known on Jupiter, and so far they possessed no Keemarnian title. To Sir John they gave his prefix, although they did not quite understand it.

A great silence reigned when the announcement was made—Kulmervan left the dais and advanced toward his guests, and this mark of homage was acknowledged by clamorous cheers from all the others who were present.

“Welcome,” said he. “I witnessed your descent upon our land. Indeed, it was I who helped to focus our ray of attraction upon your vessel and helped to draw you into our atmosphere.”

“What are your rays?” asked Alan. “Surely you had never any cause to use one before?”

“Indeed, yes, my friend. Some time ago, some of our Keemarnians, while experimenting in the Heavens, found themselves outside our atmosphere. They never returned. Across the roadway between the red planet ‘Mydot’—Mars I think you call it—and ourselves, are many rapidly moving meteoric bodies. We fear that our gallant brothers met one of these, and were destroyed. Many men of science went after these lost ones but none ever returned. Through our wonderful glass, we saw one of our air birds in space; it was unable to reach home. Then was the great magnetic ray discovered. In the shortest space of time it was perfected, and played on the silent air bird. Gradually it was drawn nearer and nearer to our shores until it was within our atmosphere, and was able to land in safety. Since that time, if air birds venture too high, we have nearly always been able to save the adventurous spirits, and in your case, we brought you safely here.”
