[104] This was a favorite notion of George Stephenson's, and he held that what produced light and heat had originally been light and heat. Mr. Fearon, solicitor, has informed the author that he accompanied Stephenson on one of his visits to Belgium, when it seemed to him that the engineer did not take much interest in the towns, churches, or public buildings of Belgium, probably because he knew little of history, and they recalled no associations with the past. One day the party went to see the beautiful Hôtel de Ville at Brussels, but Stephenson did not seem moved by it. On passing out of the square, however, by the little street which leads toward the Montague de la Cour, his interest was thoroughly roused by the sight of an immense fat pig hung up in a butcher's shop. He immediately took out his foot-rule, measured the pig, and expressed a desire to have some conversation with the butcher as to how it had been fed. The butcher accordingly waited upon them at the hotel, and told all he knew about the feeding of the pig; and then, says Mr. Fearon, "George went off into his favorite theory of the sun's light, which he said had fattened the pig; for the light had gone into the pease, and the pease had gone into the fat, and the fat pig was like a field of coal in this respect, that they were, for the most part, neither more nor less than bottled sunshine."
[105] The second Mrs. Stephenson having died in 1845, George married a third time in 1848, about six months before his death. The third Mrs. Stephenson was an intelligent and respectable lady, who had for some years officiated as his housekeeper.
[106] The dams of "crib-work" were formed by laying flattened pine logs along the whole outer edge of the work, and at intervals of from 5 to 10 feet parallel therewith throughout the whole of the breadth, connected with transverse timbers firmly treenailed and notched into them. When one course was formed, another was laid upon and firmly treenailed to it. After two or three courses were laid, transverse timbers were placed over them close together, so as to form a flooring, on which stone was placed to suit the crib as the work progressed. When the under side of the crib touched the bottom, it was carefully filled with loose stones and clay puddle to the water level. The process of puddling and pumping out the water, and building up the pier within the dam thus formed, then proceeded in the usual manner. In some cases a powerful steam dredge was employed to clear out the puddle-chambers.
[107] Mr. Stephenson entertained a very strong opinion as to the inexpediency of making this canal, and the impracticability of keeping it open except at an enormous expense. Of course it was possible to make the canal provided there was money enough raised for the purpose. But, even if made, he held that it would not long be used, for there would not be traffic enough to pay working expenses. In 1846, Mr. Stephenson carefully examined the country along the line of the proposed canal, from Tineh on the Mediterranean, to Suez on the Red Sea, in company with the agents of M. Talabot, a French engineer, and M. de Negrelli, an Austrian engineer. They ascertained that there was no difference of level between the two seas, and that consequently a canal capable of being scoured by the waters of either was impracticable. On the occasion of Captain Pim's reading a paper on the subject of the revived project of the canal before the Geographical Society on the 11th of April, 1859, Mr. Stephenson took part in the discussion which followed. He held that any harbor constructed at Port Said, however far it might be extended into the sea, would only act as a mud-trap, and that it would be impracticable to keep such a port open. Mr. George Rennie had compared the proposed breakwater at Pelusium with the breakwater at Portland, on which Mr. Stephenson observed, "Why, at Portland, the stones are carried out from the shore and thrown into the sea, but at Pelusium there is no solid shore, and all the stones must be brought 100 miles. Can there be any comparison between a breakwater at Portland and one in the Mediterranean on a lee-shore, where there is no stone and no foundation whatever? It is only the silt of the Nile. The Nile brings down millions of tons of mud yearly, and hence the Delta formed at its mouth. The moment you construct a harbor at Port Said and project piers into the sea, you immediately arrest the course of the mud, and will never be able to keep the port open. It would be the most extraordinary thing in the world to project two jetties into an open sea on a lee-shore, which has for almost three months in the year a northeast wind blowing upon it. There is no seaman, except in fair weather, who would venture to approach such a place. To render it at all accessible and safe, there must be a harbor of refuge made, and we know from experience in our own country what a large question that would open up. But even suppose such a harbor to be made. The current carries the mud of the Nile in an easterly direction; and if you provide a harbor of refuge, which means a quiescent harbor, it will act merely as a gigantic mud-trap. I believe it to be nearly if not absolutely true, that there is no large harbor in the world maintained on the delta of a large river. Any such harbor would be silted up in a few years. And whoever has traveled over the district between Port Said and Suez, and seen the moving sands, must see that it would be necessary to dredge, not only that harbor, but the canal itself." Mr. Stephenson's conclusion accordingly was that the scheme was impracticable, that it would not justify the expenditure necessary to complete it, and that, if ever executed, it would prove a commercial failure.
