ENGINEERING EVIDENCE. Usually the most profitable part of the present railway mania consists in persons going before the committees of the House of Commons, to give what is called engineer- ing evidence. Engineers are consequently in very great request; and, while they are at their present tremendous premium, Punch has it in contemplation to take a few. pupils, and qualify them for giving their testimony at ten guiueas a day from each Committee before which they are examined. Punch undertakes to qualify any person to pass an examination in the following triumphant style, for a bonus of ta0 and a share in the profits of the evidence;- Q. Now, Sir, can you explain the engineering advan- tages of this line? A. I can. Q. Do so if you please in your own manner. A. It is obvious that if I take a mean isosceles triangle of three and a quarter, it gives a gradient of five to the square inch, and thus tunnelling will be avoided through at least one-half the line. ° Q. But how about the embankments ? I. Cl,t a square inch out of a rhomboid, and throw i on at right angles, it is clear that there can be no sup- port to the sides. If on the other hand, I establish a fulcrum on the surface of a spheroid plane, it is impossi- ble that the embankments can fall in and this, I take it, is the great advantage of the proposed line. The Chairman -Allow us to ask, Sir, whether you think a gradient of two will be sufficient? A.-Certainly I do. If I had a lever and a screw now in the room, I would undertake to show in five minutes that a patent axle working on a broad gauge and going consecutively in rotation after a double stuffing box would be of itself sufficient to do all that was required. his an9wer caused the greatest excitement in the L'i Lomnuttee-room, and strangers were at once ordered to withdraw that the Committee might deliberate. In 8 •»« J a ^uar^er °f an hour the public were re-ad- mi ted, and the Chairman said he had only one more question to ask of the last witness. It was simply this -Can it be possible for the broad gauge to wear out the cylinder of a single valve, without tearing off the siphon- cock from the main boiler 1 The witness, after making a few drawings in his note- hook, and a TeFereoee to a five foot rule, with which he measured the table in three different directions, answered diliberately, • and with great emphasis-Certaiuly not. f ,e V., Irifau immediately announced the preamble o ue Bill to be proved; and the rush to the door was so overwhelming that our reporter was carried into group Z, and thence into Palace-yard cab stand. Ex- presses were waiting for every part of the kingdom, and shares immediately went up to 75, at which everybody, refused to realise; but a flaw having been discovered, after every one had left the room, and before the Com- mittee had finally broken up, the Bill was subsequently, declared to be lost, and the shares fell to 2, with a down ward tendency—Punch.
