As seen in the engraving (reproduced from Engi-neering) there is no diaphragm plate and no netting. Thereis something occult In the adjustment of the exhaust nozzleson this road for high speed engines, and I suspect that thenozzles are not exactly vertical. The axis of the nozzle is. A.

Whether there is anythingin it I cannot say, but the fact remains that the last adjust-ment ot the new ten-wheel engine which resulted in fine steam-ing, consisted in a slight tipping of the nozzle. This fact, at least, serves to indicate how carefully the drafting is done, andthat is the important fact to be brought out. These parts receivethat is the important fact to be brought out. The brick archreceives as careful attention as the drafting, and these little en-gines steam well without tearing their boilers all to pieces. An exceedingly important feature of British locomotive prac-tice is the fact that the appearance of a new design is con-sidered an epoch-making event in the department. It isprepared for perhaps two years in advance. The study putupon the drawings Is something unknown with us, and
