"I, Omar, Prince of Mo, vouch for each man's honesty," exclaimed my friend, interrupting. At these words the chief guardian of the gate bowed until his long white beard swept the ground, and we passed on, followed by Kona and our black companions, in whom the denizens of the mysterious place seemed highly interested, never before having seen negro savages. Now and then as we passed along voices raised in dissension that strangers should be admitted to the inaccessible kingdom reached our ears, but these were drowned by the wild plaudits of the crowd. On every hand Omar was greeted with an enthusiasm befitting the heir to the Emerald Throne, and he, in response, bowed his head from side to side, as with royal gait he strode down the broad handsome thoroughfare. The buildings on either hand were magnificent in their proportions, built of enormous blocks of grey stone finely sculptured, with square ornamented windows. Apparently the manufacture of glass was unknown, for all the windows were uniformly latticed. Here and there through the open doors we caught sight of cool courtyards, with trees and plashing fountains beyond, while from the flat roofs that here seemed to be the principal promenade of the ladies, as in Eastern lands, white hands and bejewelled arms waved us dainty welcome. Across a great market square, where slaves were being bought and sold, and business was proceeding uninterruptedly, we passed, and as we glanced at the unfortunate ones huddled up in the scanty shadow, we remembered the day when we, too, had been sold by our bitter and well-hated enemy, Samory. I smiled as I reflected what terrible revenge this great army of the Naya could wreak upon the Arab chief, and found myself anticipating the day when the soldiery of Mo should gather before the old villain's stronghold. Kona, who had come up beside me, walked on in silent amazement. He knew nothing of civilization, and the sights he now witnessed held him dumb. The African mind is slow to understand the benefits of civilization and modern progress, unless it be the substitution of guns for bows and bullets for arrows. At last we turned a corner suddenly, and saw before us, rising against the intensely blue sky and flashing in the brilliant sunlight, the three great gilded domes of the royal palace. "Gold!" cried Kona, in an awed tone. "See!" and he turned to several of his sable brethren. "See! they build their great huts of solid gold! What treasure they must have!" As we advanced in imposing procession, the great gate of this royal residence, grim and frowning as a fortress, over which a large flag was floating, bearing the sign of the vampire bat, opened wide, and, unchallenged by the crowds of gaily-dressed soldiers drawn up in line and saluting, we went forward amid vociferous cheering.
