As they proceeded up a street they encountered a pair of sturdy Africans carrying a sedan-chair attached to a couple of poles. Its sides were surrounded with gaudy curtains, for the protection of the timid señorita seated within from the bold gaze of the common multitude. Walking behind it were Botts, Old Grizzly, and the Long Green Boy, who appeared to have attached themselves to the procession as a committee of investigation; while, ranging up alongside, like a vigilant cruiser about to overhaul a suspicious craft in quest of a contraband cargo, was the adventurous Moses in a prodigious state of excitement, staring at the object of his amazement with dilated eyes, in blissful ignorance of his dangerous proximity to a petticoat. But great was his consternation when informed that there was a young lady behind the curtain. He started back with a terrified expression; and the Professor afterwards said that had not his limbs failed him, and his knees come in collision, like bones in the hands of an Ethiopian serenader, they would have been entertained with the sight of a desperate fugitive darting up the street with the caudal appendage to his coat taking a horizontal projection as he hurried along. Having during the day visited various localities in the city, they returned to the hotel, and on the following morning proceeded on an expedition to the Imperial gardens. They rode in a huge omnibus drawn by four couples of mules, and navigated by four adventurous natives, each seated on the back of one of the animals, with prodigious rowels on his heels, which seemed to indicate a ruthless determination to gore out the vitals of the beast if he showed the least signs of a refractory disposition, and dared to dispute the supremacy of the rider. Under the shade of cocoa- and coffee-trees they rumbled over the road, and at length arrived at the gates of the gardens. This inclosure, equal in area to a large farm, was cultivated with great care and filled with every variety of flowers and fruitage. At intervals, among the trees, were fanciful little tenements for the accommodation of those whose business it was to plant and to prune. Tom Seddon became poetic, and declared that they had discovered a paradise in which an Adam and Eve were probably then dwelling in immortal youth and innocence. After exploring the gardens for several hours, the Professor seated himself in a beautiful arbor, and, while the gorgeous butterflies and birds of variegated and magnificent plumage were flitting around him, he sang: The op'ning rose doth brightly glow With pearly dews of even, Like a fragment fall'n from yonder bow, Which hangeth like Hope in the heaven. And gayly on a golden wing, At the sweet evening hour, The humming-bird comes like a fairy thing To flit round the beautiful flower.
