" 't see 's wrong," remarked Jim, gruff tones " , it isn't as wrong as some other things What's going of us now ? "

"I don't know," answered the boy, looking around him curiously

The houses city were all made of glass, so clear and transparent that one could look walls as easily as through window Dorothy saw, underneath the roof she stood, several rooms used for rest chambers, and even thought make out number of queer forms huddled corners rooms

The roof beside them had great hole smashed through it, and pieces of glass were lying scattered in every direction nearby steeple broken off short fragments lay heaped beside it Other buildings were cracked in places or had corners chipped off ; but been very beautiful before these accidents had happened to mar their perfection The rainbow tints colored suns fell glass city softly and gave buildings many delicate, shifting hues which were very pretty

But not sound had broken the stillness strangers had arrived, except that own voices They began to wonder if there were no people to inhabit this magnificent city inner world

Suddenly man appeared through hole roof next one they were on and stepped into plain view not very large man, but was well formed and had beautiful face--calm and serene face of fine portrait His clothing fitted his form snugly and was gorgeously colored in brilliant shades of green, which varied sunbeams touched them but was not wholly influenced solar rays

The man had taken step or two across the glass roof before he noticed the presence strangers; but then he stopped abruptly no expression of either fear or surprise upon his tranquil face, yet been both astonished and afraid; for after his eyes had rested ungainly form horse for moment he walked rapidly furthest edge roof, his head turned back over his shoulder to gaze strange animal

"Look out ! " cried Dorothy, who noticed beautiful man look where going; "be careful, or you'll fall off ! "

But he paid no attention to her warning He reached the edge tall roof, stepped one foot out air, and walked into space as calmly he were on firm ground

The girl, greatly astonished, ran to lean over the edge roof, and saw the man walking rapidly air toward the ground Soon he reached the street and disappeared through glass doorway into glass buildings

"How strange ! " she exclaimed, drawing long breath

"Yes; but it's lots of fun, strange," remarked the small voice kitten, and Dorothy turned her pet walking air foot or so away edge roof

"Come back, Eureka ! " she called, in distress, "you'll certainly be killed "

" nine lives," said the kitten, purring softly as it walked around in circle and then came back roof; "but 't lose even by falling country, because I really couldn't manage if to "

"Does the air bear up your weight ? " asked the girl

" ; can't ? " and again the kitten wandered air and back edge roof

"It's wonderful ! " said Dorothy

"Suppose we let Eureka go down street and get some one to ," suggested Zeb, who even more amazed than Dorothy strange happenings

"Perhaps walk air ourselves," replied the girl

Zeb drew back with shiver

"I wouldn't dare try,"

"Maybe Jim will go," continued Dorothy, looking horse

"And maybe he won't ! " answered Jim "I've tumbled air long enough me contented roof "

"But we didn't tumble roof," said the girl; " we reached here we were floating very slowly, and I'm almost sure float down street without getting hurt Eureka walks air all right "

"Eureka weights only about half pound," replied the horse, in scornful tone, "while I weigh about half ton "

"You don't weigh ought to, Jim," remarked the girl, shaking her head as she looked animal "You're dreadfully skinny "

"Oh, well; I'm old," said the horse, hanging his head despondently, "and I've had lots of trouble in my day, little one For years I drew public cab in Chicago, 's enough anyone skinny "

"He eats enough fat, I'm sure," said the boy, gravely

"Do I ? remember any breakfast that I've had today ? " growled Jim, he resented Zeb's speech

"None of us has had breakfast," said the boy; "and in time of danger like this it's foolish about eating "

"Nothing is more dangerous than being without food," declared the horse, with sniff rebuke young master; "and just at present no one can tell whether any oats queer country or not , liable glass oats ! "

"Oh, no ! " exclaimed Dorothy " plenty of nice gardens and fields down below us, edge city But find way ground "

"Why don't you walk down ? " asked Eureka "I'm as hungry horse is, and my milk "

" try it, Zeb" asked the girl, turning to her companion

Zeb hesitated still pale and frightened, dreadful adventure had upset him and made him nervous and worried But wish the little girl him coward, so he advanced slowly edge roof

Dorothy stretched out hand to him and Zeb put one foot out and let it rest air little over the edge roof It seemed firm enough to walk upon, so courage and put out the other foot Dorothy kept hold hand and followed him, and soon they were both walking air, kitten frisking beside them

"Come on, Jim ! " called the boy "It's all right "

Jim had crept edge roof to look over, and being sensible horse and quite experienced, up his mind that go where the others did So, with snort and neigh and whisk short tail he trotted off the roof air and at once began floating downward street His great weight made him fall faster children walked, and he passed them way down; but when glass pavement he alighted upon it so softly that not even jarred

"Well, well ! " said Dorothy, drawing long breath, "What strange country "

People began glass doors to look new arrivals, and pretty soon quite crowd had assembled There were , but no children at all, folks were all beautifully formed and attractively dressed and had wonderfully handsome faces not an ugly person in all the throng, yet Dorothy was not especially pleased appearance people because their features had no more expression faces of dolls smile nor did they frown, or show either fear or surprise or curiosity or friendliness They simply started strangers, paying most attention to Jim and Eureka, for they had never before seen either horse or cat children bore an outward resemblance to themselves

Pretty soon man joined the group who wore glistening star dark hair just over his forehead person of authority, others pressed back him room After turning his composed eyes first animals and then children to Zeb, who was little taller than Dorothy:

"Tell me, intruder, you who caused the Rain of Stones ? "

For moment the boy know what he meant question Then, remembering the stones that had fallen and passed them long had reached this place, he answered:

"No, sir; we didn't cause anything It earthquake "

The man star stood for time quietly thinking over this speech Then he asked:

" an earthquake ? "

"I don't know," said Zeb, who was still confused But Dorothy, seeing his perplexity, answered:

"It's shaking earth quake big crack opened and we fell through--horse and buggy, and all-- stones got loose and came down "

The man star regarded her calm, expressionless eyes

"The Rain of Stones much damage to our city," ; "and hold you responsible unless prove your innocence "

"How can we ? " asked the girl
