But, as I was saying, after one of the most awful catastrophes that ever took place, the bursting of a boiler which scalded to death forty-one members of Congress, (on their way home,) besides upwards of thirty women and children, and nine of the crew, the people of this country began to arouse themselves, and very severe laws were enacted. Before, however, any farther loss of lives occurred, a stop was put to the use of steamboats altogether. The dreadful accident of which I spoke occurred in the year 1850, and in that eventful year a new power was brought into use, by which steamboats were laid aside for ever."
"What is the new principle, and who first brought it to light?"
