Mr. Crowther was prepared to receive them. A table was placed in the middle of the room, and on it a dish, in which were a few drops of sulphuric acid, so placed that a slight motion of the table would cause it to flow into a mixture of chlorate of potassa and white sugar. An English clock was also in the room, from which a cock issued every hour and crowed. It was arranged that the explosion from the dish, and the crowing of the rooster, should take place at the same moment. The whole thing was to be decided in favor of the party who should perform the greatest wonder. After all were seated, Mr. Crowther made a harangue, and requested them to say who should lead off in the contest. This privilege they accorded to him. The doors were closed, the curtains drawn, and all waited in breathless silence. Both the hands on the clock were fast approaching the figure twelve. Presently the cock came out and began crowing, to the utter astonishment of the learned visitors. Crowther gave the table a jostle; and suddenly, from the midst of the dish burst forth flame and a terrible explosion. This double wonder was too much for these sages. The scene that followed is indescribable. One fellow rushed through the window and scampered; one fainted and fell upon the floor; another, in his consternation, overturned chairs, tables, and everything in his way, took refuge in the bedroom, under the bed, from which he was with difficulty afterwards removed. It need not be added that they gave no more trouble, and the practice they sought to break up was the more increased for their pains.[32] In Southern Guinea, and especially in the Gabun country, the natives are unsurpassed for their cunning and shrewdness in trade; and even in everything in the way of dealing with strangers. The following anecdote will illustrate how easily they can turn matters to their own account.
