It is not necessary to state that to have passed through his severe ordeal scatheless needed no small amount of courage, intelligence, and ready shrewdness on the part of the witness. Nicholas Wood, who was present on the occasion, has since stated that the point on which Stephenson was hardest pressed was that of speed. "I believe," he says, "that it would have lost the company their bill if he had gone beyond eight or nine miles an hour. If he had stated his intention of going twelve or fifteen miles an hour, not a single person would have believed it to be practicable." Mr. Alderson had, indeed, so pressed the point of "twelve miles an hour," and the promoters were so alarmed lest it should appear in evidence that they contemplated any such extravagant rate of speed, that immediately on Mr. Alderson sitting down, Mr. Joy proceeded to re-examine Stephenson, with the view of removing from the minds of the committee an impression so unfavorable, and, as they supposed, so damaging to their case. "With regard," asked Mr. Joy, "to all those hypothetical questions of my learned friend, they have been all put on the supposition of going twelve miles an hour: now that is not the rate at which, I believe, any of the engines of which you have spoken have traveled?" "No," replied Stephenson, "except as an experiment for a short distance." "But what they have gone has been three, five, or six miles an hour?" "Yes." "So that those hypothetical cases of twelve miles an hour do not fall within your general experience?" "They do not." The committee also seem to have entertained some alarm as to the high rate of speed which had been spoken of, and proceeded to examine the witness farther on the subject. They supposed the case of the engine being upset when going at nine miles an hour, and asked what, in such a case, would become of the cargo astern. To which the witness replied that it would not be upset. One of the members of the committee pressed the witness a little farther. He put the following case: "Suppose, now, one of these engines to be going along a railroad at the rate of nine or ten miles an hour, and that a cow were to stray upon the line and get in the way of the engine; would not that, think you, be a very awkward circumstance?" "Yes," replied the witness, with a twinkle in his eye, "very awkward--_for the coo_!" The honorable member did not proceed farther with his cross-examination; to use a railway phrase, he was "shunted." Another asked if animals would not be very much frightened by the engine passing at night, especially by the glare of the red-hot chimney? "But how would they know that it wasn't painted?" said the witness.
