Mr. JDodds was the first pupil of the late George Stephenson, but prior to that was in his uncle Mr. Ralph Dodd’s office, at Killingworth, then intending to be a colliery viewer. He succeded Mr. Nicholas Wood, anc lias frequently, when a boy, paid George Stephc son’s wages when he wore his working dress, and is believed to be the only one living, who, with Nicholas Wood, William and John. Moody, Wales* and Summersides, the viewers and overmen, and others, amounting to seventeen in number, accompanied “ George ” to the bl°wer, down the Killingworth pit, to try the first safetylamp, in November, 1815, Mr. Dpdds, when a boy, left his uncle and became a pupil to Stephenson, preferring mechanics, and from that date, with a slight exception, was always interested in every improvement, and consulted by Mr. Stephenson in matters connected with locomotive and railway works, especially the mechanical. From 1832 to 1836 Mr. Dodds was the engineer for the Horseley Coal and Iron Company, |n Staffordshire, then a firm of great repute, and here lie took up the question with Stephenson, Locke, Rastrick, and others as to making heavier locomotive engines than were at that time used, and raking railway lines to. be worked by locomotive engines much steeper, whereby much expense might be saved 111 cutting, c.; in this he was opposed by one and all, and only after having had a consultation with Mr. Charles Vignoles, then the engineer op the St. Hlt; in’s and Runcorn Gap Railway, where they were working with two distinct locomotive establishments, one at the top and the other at the bottom of the incline plane which crossed over the Liverpool and Manchester Railway; this incline was worked by fixed engine and rope. Mr. Dodds proposed to make a locomotive engine and to take a larger load than the fixed engine. Mr. Vignoles persuaded the directors to give the order; and, to his credit, aided the carrying out o Mr. Dodds’1 iews, which have become all but universal; the engipc was made, and did the work prescribed well, an the fixed epgine was taken away. Since that day heavy inclines, which before it was thought could not be worked by locomotive engipes pro now so worked, and some of many miles in length. Mr. Dodds, in the first instance/fought tips battle sipgle-hapded, hut found ip Mr. Vignoles or who rps always ready to listep to improvements, and was consulted by lum in the drawing up pf the specification for the locomotive engines for the Dublin and Kingston Railway, and for him Mr. i odds made a sketch, that each locomotive should be a perfect duplicate of the thei and eact detailed part of said engine should also be a duplicate of any other engine, o that the whole family shppld be exactly the same size, weight, and JcLd, and thus a very small stock of detached parts need be kept in the stores.”
