“Good, you shall have it,” returned the Secretary, with a laugh. “I see you are going to give us big surprises to-morrow.”

“You are right, I am,” said Mark, as the Secretary left him to execute his mission.

Armed with an order, Mark left the palace and hurried through the steep narrow streets of the town, until he reached a piece of road that was being mended by four slaves in long chains. That morning Mark had observed that his friend the crocodile was one of the four. Passing close enough to attract the attention of the poor fellow, he whispered, without stopping, “Mamba, expect me to-morrow.”

This he had said in the native tongue, having by that time acquired a few sentences, of which he made the best and most frequent use possible.

Going to the guard of these slaves, he presented his paper, and said that he should come personally for them early in the morning. Then he returned to the laboratory and assisted his comrades to load the firework cases with various kinds of “fire,” stars, golden rain, etcetera. The young cannon especially was loaded, with a succession of surprises, to the very muzzle, before midnight.

“Suppose he bust!” suggested Ebony, with a solemn visage. “De Queen ob Madigascur be blow’d into middle ob nixt week—hey?”

“I shall take precautions against that, Ebony. In the first place, I’ll have it buried in the earth up to the muzzle, and, in the second place, I’ll not place it too near her Majesty.”

When all was prepared the wearied triumvirate retired to rest, each to dream of the subjects that lay nearest his heart and imagination at the moment. Hockins dreamed of tobacco-pipes and explosions; Mark dreamed of freed slaves, thunder-struck queens, eloping lovers and terrible consequences; and Ebony dreamed of incomprehensible situations, crashing thunderbolts, and unimaginable coruscations of resplendent fire!
