distress.'
'That's right,' returned the Ork, cocking its head sidewise in a cheerful manner, and then for a few minutes there was silence while they all ate of the biscuits. After a while Trot said:
'I've never seen or heard of an Ork before. Are there many of you?'
'We are rather few and exclusive, I believe,' was the reply. 'In the country where I was born we are the absolute rulers of all living things, from ants to elephants.'
'What country is that?' asked Cap'n Bill.
'Orkland.'
'Where does it lie?'
'I don't know, exactly. You see, I have a restless nature, for some reason, while all the rest of my race are quiet and contented Orks and seldom stray far from home. From childhood days I loved to fly long distances away, although father often warned me that I would get into trouble by so doing.
''It's a big world, Flipper, my son,' he would say, 'and I've heard that in parts of it live queer two-legged creatures called Men, who war upon all other living things and would have little respect for even an Ork.'
'This naturally aroused my curiosity and after I had completed my education and left school I decided to fly out into the world and try to get a glimpse of the creatures called Men. So I left home without saying good-bye, an act I shall always regret. Adventures were many, I found. I sighted men several times, but have never before been so close to them as now. Also I had to fight my way through the air, for I met gigantic birds, with fluffy feathers all over them, which attacked me fiercely. Besides, it kept me busy escaping from floating airships. In my rambling I had lost all track of distance or direction, so that when I wanted to go home I had no idea where my country was located. I've now been trying to find it for several months and it was during one of my flights over the ocean that I met the whirlpool and became its victim.'
Trot and Cap'n Bill listened to this recital with much interest, and from the friendly tone and harmless appearance of the Ork they judged he was not likely to prove so disagreeable a companion as at first they had feared he might be.
The Ork sat upon its haunches much as a cat does, but used the finger-like claws of its front legs almost as cleverly as if they were hands. Perhaps the most curious thing about the creature was its tail, or what ought to have been its tail. This queer arrangement of skin, bones and muscle was shaped like the propellers used on boats and airships, having fan-like surfaces and being pivoted to its body. Cap'n Bill knew something of mechanics, and observing the propeller-like tail of the Ork he said:
'I s'pose you're a pretty swift flyer?'
'Yes, indeed; the Orks are admitted to be Kings of the Air.'
'Your wings don't seem to amount to much,' remarked Trot.
'Well, they are not very big,' admitted the Ork, waving the four hollow skins gently to and fro, 'but they serve to support my body in the air while I speed along by means of my tail. Still, taken altogether, I'm very handsomely formed, don't you think?'
Trot did not like to reply, but Cap'n Bill nodded gravely. 'For an Ork,' said he, 'you're a wonder. I've never seen one afore, but I can imagine you're as good as any.'
That seemed to please the creature and it began walking around the cavern, making its way easily up the slope while it was gone, Trot and Cap'n Bill each took another sip from the water-flask, to wash down their breakfast.
'Why, here's a hole—an exit—an outlet!' exclaimed the Ork from above.
'We know,' said Trot. 'We found it last night.'
'Well, then, let's be off,' continued the Ork, after sticking its head into the black hole and sniffing once or twice. 'The air seems fresh and sweet, and it can't lead us to any worse place than this.'
The girl and the sailor-man got up and climbed to the side of the Ork.
'We'd about decided to explore this hole before you came,' explained Cap'n Bill; 'but it's a dangerous place to navigate in the dark, so wait till I light a candle.'
'What is a candle?' inquired the Ork.
'You'll see in a minute,' said Trot.
The old sailor drew one of the candles from his right-side pocket and the tin matchbox from his left-side pocket. When he lighted the match the Ork gave a startled jump and eyed the flame suspiciously; but Cap'n Bill proceeded to light the candle and the action interested the Ork very much.
'Light,' it said, somewhat nervously, 'is valuable in a hole of this sort. The candle is not dangerous, I hope?'
'Sometimes it burns your fingers,' answered Trot, 'but that's about the worst it can do—'cept to blow out when you don't want it to.'
Cap'n Bill shielded the flame with his hand and crept into the hole. It wasn't any too big for a grown man, but after he had crawled a few feet it grew larger. Trot came close behind him and then the Ork followed.
'Seems like a reg'lar tunnel,' muttered the sailor-man, who was creeping along awkwardly because of his wooden leg. The rocks, too, hurt his knees.
For nearly half an hour the three moved slowly along the tunnel, which made many twists and turns and sometimes slanted downward and sometimes upward. Finally Cap'n Bill stopped short, with an exclamation of disappointment, and held the flickering candle far ahead to light the scene.
'What's wrong?' demanded Trot, who could see nothing because the sailor's form completely filled the hole.
'Why, we've come to the end of our travels, I guess,' he replied.
'Is the hole blocked?' inquired the Ork.
'No; it's wuss nor that,' replied Cap'n Bill sadly. 'I'm on the edge of a precipice. Wait a minute an' I'll move along and let you see for yourselves. Be careful, Trot, not to fall.'
Then he crept forward a little and moved to one side, holding the candle so that the girl could see to follow him. The Ork came next and now all three knelt on a narrow ledge of rock which dropped straight away and left a huge black space which the tiny flame of the candle could not illuminate.
'H-m!' said the Ork, peering over the edge; 'this doesn't look very promising, I'll admit. But let me take your candle, and I'll fly down and see what's below us.'
'Aren't you afraid?' asked Trot.
'Certainly I'm afraid,' responded the Ork. 'But if we intend to escape we can't stay on this shelf forever. So, as I notice you poor creatures cannot fly, it is my duty to explore the place for you.'
Cap'n Bill handed the Ork the candle, which had now burned to about half its length. The Ork took it in one claw rather cautiously and then tipped its body forward and slipped over the edge. They heard a queer buzzing sound, as the tail revolved, and a brisk flapping of the peculiar wings, but they were more interested just then in following with their eyes the tiny speck of light which marked the location of the candle. This light first made a great circle, then dropped slowly downward and suddenly was extinguished, leaving everything before them black as ink.
'Hi, there! How did that happen?' cried the Ork.
'It blew out, I guess,' shouted Cap'n Bill. 'Fetch it here.'
'I can't see where you are,' said the Ork.
So Cap'n Bill got out another candle and lighted it, and its flame enabled the Ork to fly back to them. It alighted on the edge and held out the bit of candle.
'What made it stop burning?' asked the creature.
'The wind,' said Trot. 'You must be more careful, this time.'
'What's the place like?' inquired Cap'n Bill.
'I don't know, yet; but there must be a bottom to it, so I'll try to find it.'
With this the Ork started out again and this time sank downward more slowly. Down, down, down it went, till the candle was a mere spark, and then it headed away to the left and Trot and Cap'n Bill lost all sight of it.
In a few minutes, however, they saw the spark of light again, and as the sailor still held the second lighted candle the Ork made straight toward them. It was only a few yards distant when suddenly it dropped the candle with a cry of pain and next moment alighted, fluttering wildly, upon the rocky ledge.
'What's the matter?' asked Trot.
