"You don't talk?" said Joe, again.

"We are looking!" said the doctor, directing his spy-glass toward the mainland.

"For my part, I must talk!"

"As much as you please, Joe; talk as much as you like!"

And Joe went on alone with a tremendous volley of exclamations. The "ohs!" and the "ahs!" exploded one after the other, incessantly, from his lips.

During his passage over the sea the doctor deemed it best to keep at his present elevation. He could thus reconnoitre a greater stretch of the coast. The thermometer and the barometer, hanging up inside of the half-opened awning, were always within sight, and a second barometer suspended outside was to serve during the night watches.

At the end of about two hours the Victoria, driven along at a speed of a little more than eight miles, very visibly neared the coast of the mainland. The doctor, thereupon, determined to descend a little nearer to the ground. So he moderated the flame of his cylinder, and the balloon, in a few moments, had descended to an altitude only three hundred feet above the soil.

It was then found to be passing just over the Mrima country, the name of this part of the eastern coast of Africa. Dense borders of mango-trees protected its margin, and the ebb-tide disclosed to view their thick roots, chafed and gnawed by the teeth of the Indian Ocean. The sands which, at an earlier period, formed the coast-line, rounded away along the distant horizon, and Mount Nguru reared aloft its sharp summit in the northwest.

The Victoria passed near to a village which the doctor found marked upon his chart as Kaole. Its entire population had assembled in crowds, and were yelling with anger and fear, at the same time vainly directing their arrows against this monster of the air that swept along so majestically away above all their powerless fury.

The wind was setting to the southward, but the doctor felt no concern on that score, since it enabled him the better to follow the route traced by Captains Burton and Speke.

Kennedy had, at length, become as talkative as Joe, and the two kept up a continual interchange of admiring interjections and exclamations.

"Out upon stage-coaches!" said one.

"Steamers indeed!" said the other.

"Railroads! eh? rubbish!" put in Kennedy, "that you travel on, without seeing the country!"

"Balloons! they're the sort for me!" Joe would add. "Why, you don't feel yourself going, and Nature takes the trouble to spread herself out before one's eyes!"

"What a splendid sight! What a spectacle! What a delight! a dream in a hammock!"

"Suppose we take our breakfast?" was Joe's unpoetical change of tune, at last, for the keen, open air had mightily sharpened his appetite.

"Good idea, my boy!"

"Oh! it won't take us long to do the cooking--biscuit and potted meat?"

"And as much coffee as you like," said the doctor. "I give you leave to borrow a little heat from my cylinder. There's enough and to spare, for that matter, and so we shall avoid the risk of a conflagration."

"That would be a dreadful misfortune!" ejaculated Kennedy. "It's the same as a powder-magazine suspended over our heads."

"Not precisely," said Ferguson, "but still if the gas were to take fire it would burn up gradually, and we should settle down on the ground, which would be disagreeable; but never fear--our balloon is hermetically sealed."

"Let us eat a bite, then," replied Kennedy.

"Now, gentlemen," put in Joe, "while doing the same as you, I'm going to get you up a cup of coffee that I think you'll have something to say about."

"The fact is," added the doctor, "that Joe, along with a thousand other virtues, has a remarkable talent for the preparation of that delicious beverage: he compounds it of a mixture of various origin, but he never would reveal to me the ingredients."

"Well, master, since we are so far above-ground, I can tell you the secret. It is just to mix equal quantities of Mocha, of Bourbon coffee, and of Rio Nunez."

A few moments later, three steaming cups of coffee were served, and topped off a substantial breakfast, which was additionally seasoned by the jokes and repartees of the guests.
