A man was despatched on a horse with the letter, and when he reached Killingworth he made diligent enquiry after the person named upon the address, “George Stephenson, Esquire, Engineer.” No such person was known in the village. It is said that the man was on the point of giving up all further search, when the happy thought struck some of the colliers’ wives who had gathered about him, that it must be “Geordie the engine-wright” the man was in search of; and to Geordie’s cottage he accordingly went, found him at home, and delivered the letter. About the end of September, Stephenson went carefully over the line of the proposed railway, for the purpose of suggesting such improvements and deviations as he might consider desirable. He was accompanied by an assistant and a chainman,—his son Robert entering the figures while his father took the sights. After being engaged in the work at intervals for about six weeks, Stephenson reported the result of his survey to the Board of Directors, and showed that by certain deviations, a line shorter by about three miles might be constructed at a considerable saving in expense, while at the same time more favourable gradients—an important consideration—would be secured. It was, however, determined in the first place to proceed with the works at those parts of the line where no deviation was proposed; and the first rail of the Stockton and Darlington Railway was laid with considerable ceremony, near Stockton, on the 23rd May, 1822. It is worthy of note that Stephenson, in making his first estimate of the cost of forming the railway according to the Instructions of the directors, set down, as part of the cost, £6200 for stationary engines, not mentioning locomotives at all. The directors as yet confined their views to the employment only of horses for the haulage of the coals, and of fixed engines and ropes where horse-power was not applicable. The whole question of steam locomotive power was, in the estimation of the public, as well as of practical and scientific men, as yet in doubt. The confident anticipations of George Stephenson, as to the eventual success of locomotive engines, were regarded as mere speculations; and when he gave utterance to his views, as he frequently took the opportunity of doing, it even had the effect of shaking the confidence of some of his friends in the solidity of his judgment and his practical qualities as an engineer.
