Evidence was called to show that the house property passed by the proposed railway would be greatly deteriorated—in some places almost destroyed; that the locomotive engines would be terrible nuisances, in consequence of the fire and smoke vomited forth by them; and that the value of land in the neighbourhood of Manchester alone would be deteriorated by no less than £20,000! Evidence was also given at great length showing the utter impossibility of forming a road of any kind upon Chat Moss. A Manchester builder, who was examined, could not imagine the feat possible, unless by arching it across in the manner of a viaduct from one side to the other. It was the old story of “nothing like leather.” But the opposition mainly relied upon the evidence of the leading engineers—not like Stephenson, self-taught men, but regular professionals. One of these, Mr. Francis Giles, C.E., had been twenty-two years an engineer, and could speak with some authority. His testimony was mainly directed to the utter impossibility of forming a railway over Chat Moss. “_No engineer in his senses_,” said he, “would go through Chat Moss if he wanted to make a railroad from Liverpool to Manchester. . . . In my judgment _a railroad certainly cannot be safely made over Chat Moss without going to the bottom __of the Moss_. The soil ought all to be taken out, undoubtedly; in doing which, it will not be practicable to approach each end of the cutting, as you make it, with the carriages. No carriages would stand upon the Moss short of the bottom. My estimate for the whole cutting and embankment over Chat Moss is £270,000 nearly, at those quantities and those prices which are decidedly correct . . . It will be necessary to take this Moss completely out at the bottom, in order to make a solid road.”
