Artemus Ward's Lecture on the Mormons at the Egyptian Hall, Piccadilly, was a great success. His humour was so entirely fresh, new, and unconventional, it took his hearers by surprise, and charmed them. His failing health compelled him to abandon the lecture after about eight or ten weeks. Indeed, during that brief period he was once or twice compelled to dismiss his audience. I have myself seen him sink into a chair and nearly faint after the exertion of dressing. He exhibited the greatest anxiety to be at his post at the appointed time, and scrupulously exerted himself to the utmost to entertain his auditors. It was not because he was sick that the public was to be disappointed, or that their enjoyment was to be diminished. During the last few weeks of his lecture-giving he steadily abstained from accepting any of the numerous invitations he received. Had he lived through the following London fashionable season, there is little doubt that the room at the Egyptian Hall would have been thronged nightly. Our aristocracy have a fine delicate sense of humour, and the success, artistic and pecuniary, of "Artemus Ward" would have rivalled that of the famous "Lord Dundreary." There are many stupid people who did not understand the "fun" of Artemus Ward's books. In their vernacular "they didn't see it." There were many stupid people who did not understand the fun of Artemus Ward's lecture on the Mormons. They could not see it. Highly respectable people--the pride of their parish, when they heard of a lecture "upon the Mormons"- -expected to see a solemn person, full of old saws and new statistics, who would denounce the sin of polygamy, and bray against polygamists with four-and-twenty boiling-water Baptist power of denunciation. These uncomfortable Christians do not like humour. They dread it as a certain personage is said to dread holy water, and for the same reason that thieves fear policemen--it finds them out. When these good idiots heard Artemus offer, if they did not like the lecture in Piccadilly, to give them free tickets for the same lecture in California, when he next visited that country, they turned to each other indignantly, and said "What use are tickets for California to us? We are not going to California. No! we are too good, too respectable, to go so far from home. The man is a fool!" One of these ornaments of the vestry complained to the doorkeepers, and denounced the lecture as an imposition; "and," said the wealthy parishioner, "as for the panorama, it's the worst painted thing I ever saw in all my life!"
