"Some time before six o'clock, a report of the firing of guns, as of the promised naval engagement on the Serpentine River, reached the ears of the same persons, many of whom seemed to be actuated by a momentary desire to change the scene of action, and to share in the fight, the report of which they had heard from afar. The manifestation of this spirit, however, was merely momentary; they quickly became more peaceably inclined; and, whether apprehensive that they might only come in to witness the _conclusion_ of the sea fight, or resolved, on more mature deliberation, to be satisfied spectators of an aerial flight, and of the destruction of 'a Fortified Castle,' which (strange to tell) was, through the aid of fire, to be transformed into the '_Temple of Peace_'--they, with a few exceptions, took the advice given them in the printed recommendations, and remained on the ground they had originally occupied. "About twenty minutes before six, the Balloon, being then sufficiently inflated, was elevated from the situation it had hitherto occupied, and the car, which was extremely splendid and brilliant, being affixed to it, Mr. Sadler, junior, mounted into the car, which was decorated with four flags. Being supplied with the necessary quantity of ballast, of cards for signals, &c., the youthful and intrepid Aëronaut, being liberated from the chains by which his chariot was confined to the ground, began to ascend in a most solemn and majestic manner, so far as the observers were concerned, yet with a degree of rapidity which must have unstrung the nerves of any one entirely unused to such lofty excursions. "The Balloon took a direction inclining towards the south-east, and was in sight for about half an hour. It was generally reported that Mrs. Henry Johnston was to have accompanied Mr. Sadler, but we could not perceive that either she, or any other lady mounted the car. "Between eight and nine o'clock, the Grand Sea Fight took place on the Serpentine River, where ships of the line, in miniature, manoeuvred and engaged, and the Battle of the Nile, was represented in little. Of this mock naval engagement on the great Serpentine Ocean, it would be extremely difficult to give any adequate description. It is, perhaps, sufficient to observe, that it was about on a par with spectacles of a similar nature, which have been frequently exhibited at the Theatres.
