"Sure. I'd 'a' told y'about him afore," says Bill, "but it wasn't time yet. He'd made the passage with us so's he could study the volkanous mountains o' Yunzano, the like o' which mountains wasn't in all the world anywhere else. He was a wonderful stoodent, so abstracted in his studies that he hadn't heard a word of what we was sayin' in the cabin this night till the capt'n sent me to call him outer his room. He was sure a noble specimen o' fair young manhood to gaze upon--'twas on'y the other day I was readin' up to the Yastor Library of a hero in one o' the best-sellers just like him: seven foot tall 'n' three foot acrost the shoulders, an' nothin' but pale pink curls to below his shoulders, an' he no sooner steps inter the cabin now, his wonderful keen, blue-gray eyes still with the absent-minded look o' the stoodent o' science, than I could see the don's daughter, the seenyohreeter, was goin' to fall wild in love with him. "The capt'n explains the situation to young Hennery. An' Hennery thinks awhile, an' by'n'by he speaks. 'Har, I have it!' he says. 'The volkaners!' an' orders h'isted up from the hold his balloon." "A balloon, Hiker--whooh!" says Wallie, an' sits closer to Bill. "A balloon, yes. Y' see, besides bein' brought up by his father to be a great chemist an' stoodent o' mountains, he was likewise professor of airology in one of our leadin' colleges. An' he fills up his balloon--the whole crew standin' by to help him pump the hot air inter it--an' then away he goes. 'In an hour, I promise you, you shall hear from me!' he says, an' we watch him soarin' 'n' soarin' 'n' soarin' till his balloon ain't no bigger than a sparrer an' higher than the large an' silvery moon. "An' all this time the wicked General Balbeezo an' his bandit army is bringin' their guns down the mountainside 'n' preparin' to blow our ship outer water. An' by'n'by they're all ready to begin, when 'Car-ra-be-ee-sss-toe!' exclaims the don--'what is that sound I hear?' I forgot to say that the last thing young Hennery did afore leavin' the ship was to put in the balloon a handful o' bombs of a powerful explosive he'd invented hisself. An' the sound the don hears is the 'ruption produced when young Hennery drops the first of them bombs into the craters o' the nearest volkaner. An', while we look, the air gets dark an' the moon hides, an' fr'm outer the top of one volkaner after another comes the most monstrous explosions, an' down the mountainside comes a nocean o' fiery, flamin' lavver, with billers 'n' billers o' black smoke floatin' up off it. An' soon we hears groans o' terror an' 'Save us! Oh, save us!' from the wicked general an' his army on the beach, an' inter the harbor they plunges with their war-horses 'n' the cannon 'n' their armer still on 'em.
