The Mayor authorized the undertaking, a balloon was made and placed at the disposal of Forster and five of his companions. They were provided with arms as they might have to defend themselves in descending, and food in case their aerial voyage should be prolonged. The departure of the balloon had been fixed for the 18th of March. It was to start in the night, and with a moderate breeze from the northeast, the party expected to arrive at the quarters of General Lee in a few hours. But the wind from the northeast was not a mere breeze. On the morning of the 18th there was every symptom of a storm, and soon the tempest broke forth, making it necessary for Forster to defer his departure, as it was impossible to risk the balloon and those whom it would carry, to the fury of the elements. The balloon, inflated in the great square of Richmond, was all ready, waiting for the first lull in the storm; and throughout the city there was great vexation at the settled bad weather. The night of the 19th and 20th passed, but in the morning the storm was only developed in intensity, and departure was impossible. On this day Cyrus Smith was accosted in one of the streets of Richmond by a man whom he did not know. It was a sailor named Pencroff, aged from thirty-five to forty years, strongly built, much sun-burnt, his eyes bright and glittering, but with a good countenance. This Pencroff was a Yankee who had sailed every sea, and who had experienced every kind of extraordinary adventure that a two-legged being without wings could encounter. It is needless to say that he was of an adventurous nature, ready to dare anything and to be astonished at nothing. Pencroff, in the early part of this year, had come to Richmond on business, having with him Herbert Brown, of New Jersey, a lad fifteen years old, the son of Pencroff’s captain, and an orphan whom he loved as his own child. Not having left the city at the beginning of the siege, he found himself, to his great displeasure, blocked. He also had but one idea: to get out. He knew the reputation of the engineer, and he knew with what impatience that determined man chaffed at his restraint. He did not therefore hesitate to address him without ceremony. “Mr. Smith, have you had enough of Richmond?” The engineer looked fixedly at the man who spoke thus, and who added in a low voice:— “Mr. Smith, do you want to escape?” “How?” answered the engineer, quickly, and it was evidently an inconsiderate reply, for he had not yet examined the man who spoke. “Mr. Smith, do you want to escape?” ““Who are you?” he demanded, in a cold voice. Pencroff made himself known. “Sufficient,” replied Smith. “And by what means do you propose to escape?” “By this idle balloon which is doing nothing, and seems to me all ready to take us!”—
