We couldn't make out what he said, but we was scared anyway, and begun to heel it back to the balloon. When we got close enough, we understood the words, and they made me sick:

"Run! Run fo' yo' life! Hit's a lion; I kin see him thoo de glass! Run, boys; do please heel it de bes' you kin. He's bu'sted outen de menagerie, en dey ain't nobody to stop him!"

It made Tom fly, but it took the stiffening all out of my legs. I could only just gasp along the way you do in a dream when there's a ghost gaining on you.

Tom got to the ladder and shinned up it a piece and waited for me; and as soon as I got a foothold on it he shouted to Jim to soar away. But Jim had clean lost his head, and said he had forgot how. So Tom shinned along up and told me to follow; but the lion was arriving, fetching a most ghastly roar with every lope, and my legs shook so I dasn't try to take one of them out of the rounds for fear the other one would give way under me.

But Tom was aboard by this time, and he started the balloon up a little, and stopped it again as soon as the end of the ladder was ten or twelve feet above ground. And there was the lion, a-ripping around under me, and roaring and springing up in the air at the ladder, and only missing it about a quarter of an inch, it seemed to me. It was delicious to be out of his reach, perfectly delicious, and made me feel good and thank- ful all up one side; but I was hanging there helpless and couldn't climb, and that made me feel perfectly wretched and miserable all down the other. It is most seldom that a person feels so mixed like that; and it is not to be recommended, either.

Tom asked me what he'd better do, but I didn't know. He asked me if I could hold on whilst he sailed away to a safe place and left the lion behind. I said I could if he didn't go no higher than he was now; but if he went higher I would lose my head and fall, sure. So he said, "Take a good grip," and he started.

"Don't go so fast," I shouted. "It makes my head swim."

He had started like a lightning express. He slowed down, and we glided over the sand slower, but still in a kind of sickening way; for it IS uncomfortable to see things sliding and gliding under you like that, and not a sound.

But pretty soon there was plenty of sound, for the lion was catching up. His noise fetched others. You could see them coming on the lope from every direc- tion, and pretty soon there was a couple of dozen of them under me, jumping up at the ladder and snarling and snapping at each other; and so we went skimming along over the sand, and these fellers doing what they could to help us to not forgit the occasion; and then some other beasts come, without an invite, and they started a regular riot down there.

We see this plan was a mistake. We couldn't ever git away from them at this gait, and I couldn't hold on forever. So Tom took a think, and struck another idea. That was, to kill a lion with the pepper-box revolver, and then sail away while the others stopped to fight over the carcass. So he stopped the balloon still, and done it, and then we sailed off while the fuss was going on, and come down a quarter of a mile off, and they helped me aboard; but by the time we was out of reach again, that gang was on hand once more. And when they see we was really gone and they couldn't get us, they sat down on their hams and looked up at us so kind of disappointed that it was as much as a person could do not to see THEIR side of the matter.

CHAPTER VI.

IT'S A CARAVAN

I WAS so weak that the only thing I wanted was a chance to lay down, so I made straight for my locker-bunk, and stretched myself out there. But a body couldn't get back his strength in no such oven as that, so Tom give the command to soar, and Jim started her aloft.

We had to go up a mile before we struck comfort- able weather where it was breezy and pleasant and just right, and pretty soon I was all straight again. Tom had been setting quiet and thinking; but now he jumps up and says:

"I bet you a thousand to one I know where we are. We're in the Great Sahara, as sure as guns!"

He was so excited he couldn't hold still; but I wasn't. I says:

"Well, then, where's the Great Sahara? In Eng- land or in Scotland?"

"'Tain't in either; it's in Africa."

Jim's eyes bugged out, and he begun to stare down with no end of interest, because that was where his originals come from; but I didn't more than half be- lieve it. I couldn't, you know; it seemed too awful far away for us to have traveled.

But Tom was full of his discovery, as he called it, and said the lions and the sand meant the Great Desert, sure. He said he could 'a' found out, before we sighted land, that we was crowding the land some- wheres, if he had thought of one thing; and when we asked him what, he said:

"These clocks. They're chronometers. You al- ways read about them in sea voyages.
