If Ferguson was the head and Kennedy the arm, Joe was to be the right hand of the expedition. He had, already, accompanied his master on several journeys, and had a smattering of science appropriate to his condition and style of mind, but he was especially remarkable for a sort of mild philosophy, a charming turn of optimism. In his sight every thing was easy, logical, natural, and, consequently, he could see no use in complaining or grumbling.
Among other gifts, he possessed a strength and range of vision that were perfectly surprising. He enjoyed, in common with Moestlin, Kepler’s professor, the rare faculty of distinguishing the satellites of Jupiter with the naked eye, and of counting fourteen of the stars in the group of Pleiades, the remotest of them being only of the ninth magnitude. He presumed none the more for that; on the contrary, he made his bow to you, at a distance, and when occasion arose he bravely knew how to use his eyes.
With such profound faith as Joe felt in the doctor, it is not to be wondered at that incessant discussions sprang up between him and Kennedy, without any lack of respect to the latter, however.
One doubted, the other believed; one had a prudent foresight, the other blind confidence. The doctor, however, vibrated between doubt and confidence; that is to say, he troubled his head with neither one nor the other.
“The moment’s at hand. It seems that we are to sail for the moon.”
“You mean the Mountains of the Moon, which are not quite so far off. But, never mind, one trip is just as dangerous as the other!”
“Dangerous! What! with a man like Dr. Ferguson?”
“I don’t want to spoil your illusions, my good Joe; but this undertaking of his is nothing more nor less than the act of a madman. He won’t go, though!”
“He won’t go, eh? Then you haven’t seen his balloon at Mitchell’s factory in the Borough?”
“I’ll take precious good care to keep away from it!”
“Well, you’ll lose a fine sight, sir. What a splendid thing it is! What a pretty shape! What a nice car! How snug we’ll feel in it!”
“Then you really think of going with your master?”
“I?” answered Joe, with an accent of profound conviction. “Why, I’d go with him wherever he pleases! Who ever heard of such a thing? Leave him to go off alone, after we’ve been all over the world together! Who would help him, when he was tired? Who would give him a hand in climbing over the rocks? Who would attend him when he was sick? No, Mr. Kennedy, Joe will always stick to the doctor!”
