But to return to the engine which we just left in the engine-house. As soon as the driver has carefully examined it, and has recorded in a book the report we have described, the “foreman of the fitters” comes to it, and examines it all over again; and if anything is found out of order which, on reference to the book, the driver has not reported, the latter is reported by the former for his negligence. A third examination is made by Mr. Walker, the chief superintending engineer of the station, a highly intelligent and valuable servant of the Company, who has charge of the repairs of the locomotive department between Camden and Tring. If HE detects any defect that has escaped the notice not only of the driver, but of the foreman of the fitters, woe betide them both! While the engine, with several workmen screwing and hammering at it, is undergoing the necessary repairs, we will consider for a moment a subject to which Englishmen always attach considerable importance, namely, its victuals and drink, or, in other words, its coke and water. There is at Camden Station a coke-factory composed of eighteen ovens, nine on each side, in which coal after being burnt for about fifty hours gives nearly two-thirds of its quantity of coke. These ovens produce about 20 tons of coke per day; but, as 50 tons per day are required for the Camden Station alone, the remaining 30 tons are brought by rail all the way from Newcastle. Indeed, with the exception of fifty ovens at Peterborough, the whole of the coke required annually for the London and North-Western Railway, amounting to 112,500 tons, of an average value of 1_l._ per ton, comes from the Northern Coal-fields. For some time there were continual quarrels between the coke suppliers and receivers, the former declaring that the Company’s waggons had been despatched from the North as soon as loaded, and the latter complaining that they had been unnecessarily delayed. A robin-redbreast settled the dispute, for, on unloading one of the waggons immediately on its arrival at Camden Station, her tiny nest with three eggs in it minutely explained that the waggon had _not_ been despatched as soon as loaded.
