There was one branch, however, of the York and North Midland Line in which he took an anxious interest, and of which he may be said to have been the projector—the branch to Scarborough, which proved one of the most profitable parts of the railway. He was so satisfied of its value, that, at a meeting of the York and North Midland proprietors, he volunteered his gratuitous services as engineer until the company was formed, in addition to subscribing largely to the undertaking. At that meeting he took an opportunity of referring to the charges brought against engineers of so greatly exceeding the estimates: "He had had a good deal to do with making out the estimate of the North Midland Railway, and he believed there never was a more honest one. He had always endeavored to state the truth as far as was in his power. He had known a contractor who, when he (Mr. Stephenson) had sent in an estimate, came forward and said, 'I can do it for half the money.' The contractor's estimate went into Parliament, but it came out his. He could go through the whole list of the undertakings in which he had been engaged, and show that he had never had any thing to do with stock-jobbing concerns. He would say that he would not be concerned in any scheme unless he was satisfied that it would pay the proprietors; and in bringing forward the proposed line to Scarborough, he was satisfied that it would pay, or he would have had nothing to do with it."

During the time that our engineer was engaged in superintending the execution of these undertakings, he was occupied upon other projected railways in various parts of the country. He surveyed several lines in the neighborhood of Glasgow, and afterward alternate routes along the east coast from Newcastle to Edinburg, with the view of completing the main line of communication with London. When out on foot in the field on these occasions, he was ever foremost in the march, and he delighted to test the prowess of his companions by a good jump at any hedge or ditch that lay in their way. His companions used to remark his singular quickness of observation. Nothing escaped his attention—the trees, the crops, the birds, or the farmer's stock; and he was usually full of lively conversation, every thing in nature affording him an opportunity for making some striking remark or propounding some ingenious theory. When taking a flying survey of a new line, his keen observation proved very useful, for he rapidly noted the general configuration of the country, and inferred its geological structure. He afterward remarked to a friend, "I have planned many a railway traveling along in a post-chaise, and following the natural line of the country." And it was remarkable that his first impressions of the direction to be taken almost invariably proved correct; and there are few of the lines surveyed and recommended by him which have not been executed, either during his lifetime or since. As an illustration of his quick and shrewd observation on such occasions, we may mention that when employed to lay out a line to connect Manchester, through Macclesfield, with the Potteries, the gentleman who accompanied him on the journey of inspection cautioned him to provide large accommodation for carrying off the water, observing, "You must not judge by the appearance of the brooks; for after heavy rains these hills pour down volumes of water, of which you can have no conception." "Pooh! pooh! don't I see your bridges?" replied the engineer. He had noted the details of each as he passed along.

Among the other projects which occupied his attention about the same time were the projected lines between Chester and Holyhead, between Leeds and Bradford, and between Lancaster and Maryport by the west coast. This latter was intended to form part of a western line to Scotland; Stephenson favoring it partly because of the flatness of the gradients, and because it could be formed at comparatively small cost, while it would open out a valuable iron-mining district, from which a large traffic in ironstone was expected. One of its collateral advantages, in the engineer's opinion, was that, by forming the railway directly across Morecambe Bay, on the northwest coast of Lancashire, a large tract of valuable land might be reclaimed from the sea, the sale of which would considerably reduce the cost of the works. He estimated that, by means of a solid embankment across the bay, not less than 40,000 acres of rich alluvial land would be gained. He proposed to carry the road across the ten miles of sands which lie between Poulton, near Lancaster, and Humphrey Head on the opposite coast, forming the line in a segment of a circle of five miles' radius. His plan was to drive in piles across the entire length, forming a solid fence of stone blocks on the land side for the purpose of retaining the sand and silt brought down by the rivers from the interior. The embankment would then be raised from time to time as the deposit accumulated, until the land was filled up to high-water mark; provision being made, by means of sufficient arches, for the flow of the river waters into the bay. The execution of the railway after this plan would, however, have occupied more years than the promoters of the West Coast line were disposed to wait, and eventually Mr. Locke's more direct but less level line by Shap Fell was adopted. A railway has, however, since been carried across the head of the bay, in a modified form, by the Ulverstone and Lancaster Railway Company; and it is not improbable that Stephenson's larger scheme of reclaiming the vast tract of land now left bare at every receding tide may yet be carried out.

While occupied in carrying out the great railway undertakings which we have above so briefly described, George Stephenson's home continued, for the greater part of the time, to be at Alton Grange, near Leicester. But he was so much occupied in traveling about from one committee of directors to another—one week in England, another in Scotland, and probably the next in Ireland, that he often did not see his home for weeks together. He had also to make frequent inspections of the various important and difficult works in progress, especially on the Midland and Manchester and Leeds lines, besides occasionally going to Newcastle to see how the locomotive works were going on there. During the three years ending 1837—perhaps the busiest years of his life[78]—he traveled by post-chaise alone upward of 20,000 miles, and yet not less than six months out of the three years were spent in London. Hence there is comparatively little to record of Mr. Stephenson's private life at this period, during which he had scarcely a moment that he could call his own.

To give an idea of the number of projects which at this time occupied our engineer's attention, and of the extent and rapidity of his journeys, we subjoin from his private secretary's journal the following epitome of one of them, on which he entered immediately after the conclusion of the heavy Parliamentary session of 1836.

Such is a specimen of the enormous amount of physical and mental labor undergone by the engineer during the busy years above referred to. He was no sooner home than he was called away again by some other railway or business engagement. Thus, in four days after his arrival at Alton Grange from the above journey into Scotland, we find him going over the whole of the North Midland line as far as Leeds; then by Halifax to Manchester, where he staid for several days on the business of the South Union line; then to Birmingham and London; back to Alton Grange, and next day to Congleton and Leek; thence to Leeds and Goole, and home again by the Sheffield and Rotherham and the Midland works. And early in the following month (October) he was engaged in the north of Ireland, examining the line, and reporting upon the plans of the projected Ulster Railway. He was also called upon to inspect and report upon colliery works, salt works, brass and copper works, and such like, in addition to his own colliery and railway business. He usually also staked out himself the lines laid out by him, which involved a good deal of labor since undertaken by assistants. And occasionally he would run up to London, attending in person to the preparation and depositing of the plans and sections of the projected undertakings for which he was engaged as engineer.

His correspondence increased so much that he found it necessary to engage a private secretary, who accompanied him on his journeys. He was himself exceedingly averse to writing letters. The comparatively advanced age at which he learned the art of writing, and the nature of his duties while engaged at the Killingworth Colliery, precluded that facility in correspondence which only constant practice can give. He gradually, however, acquired great facility in dictation, and had also the power of laboring continuously at this work, the gentleman who acted as his secretary in the year 1835 having informed us that during his busy season he one day dictated no fewer than thirty-seven letters, several of them embodying the results of much close thinking and calculation. On another occasion he dictated reports and letters for twelve continuous hours, until his secretary was ready to drop off his chair from sheer exhaustion, and at length pleaded for a suspension of the labor. This great mass of correspondence, though closely bearing on the subjects under discussion, was not, however, of a kind to supply the biographer with matter for quotation, or to give that insight into the life and character of the writer which the letters of literary men so often furnish. They were, for the most part, letters of mere business, relating to works in progress, Parliamentary contests, new surveys, estimates of cost, and railway policy—curt, and to the point; in short, the letters of a man every moment of whose time was precious.

Fortunately, George Stephenson possessed a facility of sleeping, which enabled him to pass through this enormous amount of fatigue and labor without injury to his health. He had been trained in a hard school, and could bear with ease conditions which, to men more softly nurtured, would have been the extreme of physical discomfort. Many, many nights he snatched his sleep while traveling in his chaise; and at break of day he would be at work, surveying until dark, and this for weeks in succession. His whole powers seemed to be under the control of his will, for he could wake at any hour, and go to work at once. It was difficult for secretaries and assistants to keep up with such a man.
