In a long letter to a friend, dated September 17, 1811, he thus describes some of the sights of London:—

"A few days since I walked about four miles out of town to a village of the name of Hackney to witness the ascension of a Mr. Sadler and another gentleman in a balloon. It was a very grand sight, and the next day the aeronauts returned to Hackney, having gone nearly fifty miles in about an hour and a half. The number of people who attended on this occasion might be fairly estimated at 300,000, such a concourse as I never before witnessed.

"When the balloon was out of sight the crowd began to return home, and such a confusion it is almost impossible for me to describe. A gang of pickpockets had contrived to block up the way, which was across a bridge, with carriages and carts, etc., and as soon as the people began to move it created such an obstruction that, in a few moments, this great crowd, in the midst of which I had unfortunately got, was stopped. This gave the pickpockets an opportunity and the people were plundered to a great amount.

"I was detained in this manner, almost suffocated, in a great shower of rain, for about an hour, and, what added to the misery of the scene, there were a great many women and children crying and screaming in all directions, and no one able to assist them, not even having a finger at liberty, they were wedged in in such a manner. I had often heard of the danger of a London crowd, but never before experienced it, and I think once is amply sufficient and shall rest satisfied with it.

"A few evenings since I visited the celebrated Vauxhall Gardens, of which you have doubtless often heard. I must say they far exceeded my expectations; I never before had an idea of such splendor. The moment I went in I was almost struck blind with the blaze of light proceeding from thousands of lamps and those of every color.

"In the midst of the gardens stands the orchestra box in the form of a large temple and most beautifully illuminated. In this the principal band of music is placed. At a little distance is another smaller temple in which is placed the Turkish band. On one side of the gardens you enter two splendid saloons illuminated in the same brilliant manner. In one of them the Pandean band is placed, and in the other the Scotch band. All around the gardens is a walk with a covered top, but opening on the sides under curtains in festoons, and these form the most splendid illuminated part of the whole gardens. The amusements of the evening are music, waterworks, fireworks, and dancing.

"The principal band plays till about ten o'clock, when a little bell is rung, and the whole concourse of people (the greater part of which are females) run to a dark part of the gardens where there is an admirable deception of waterworks. A bridge is seen over which stages and wagons, men and horses, are seen passing; birds flying across and the water in great cataracts falling down from the mountains and passing over smaller falls under the bridges; men are seen rowing a boat across, and, indeed, everything which could be devised in such an exhibition was performed.

"This continues for about fifteen minutes, when they all return into the illuminated part of the gardens and are amused by music from the same orchestra till eleven o'clock. They then are called away again to the dark part of the gardens, where is an exhibition of the most splendid fireworks; sky-rockets, serpents, wheels, and fountains of fire in the greatest abundance, occupying twenty minutes more of the time.

"After this exhibition is closed, they again return into the illuminated parts of the gardens, where the music strikes up from the chief orchestra, and hundreds of groups are immediately formed for dancing. Respectable ladies, however, seldom join in this dance, although gentlemen of the first distinction sometimes for amusement lend a hand, or rather a foot, to the general cheerfulness.

"All now is gayety throughout the gardens; every one is in motion, and care, that bane of human happiness, for a time seems to have lost her dominion over the human heart. Had the Eastern sage, who was in search of the land of happiness, at this moment been introduced into Vauxhall, I think his most exalted conceptions of happiness would have been surpassed, and he would rest contented in having at last found the object of his wishes.
