for we shall be obliged to rise here to about 500 or 600 feet."
"That is a first-rate idea of yours, sir," said Joe; "the movement is neither difficult nor fatiguing; just turn a tap, and it is all done."
"We shall be more comfortable," said Kennedy, "when the balloon is higher up; the reflection from that red sand is very trying."
"What splendid trees those are!" exclaimed Joe; "though quite natural, they are magnificent. Why, a dozen of them would make a forest!"
"They are the 'baobab,'" replied Doctor Ferguson. See, one of their trunks must be almost 100 feet in circumference. It was, perhaps, at the trunk of that very tree that the unfortunate Frenchman, Maizan, was murdered in 1845, for we are just above the village of Deje la Mhora, whither he penetrated alone.

"I hope I shall not be stopped in that way," said Joe.
"Up higher, sir, if you have any regard for me."
"And the more willingly, Joe, that Mount Duthumi is peering at us. If my calculations be correct, we shall have passed it before 7 P.M."

About half-past six the "Victoria" was opposite Mount Duthumi. It was necessary, to avoid it, to rise more than
