Then, after many months' work, the men advanced out on to the open plain. For weeks and months trains of trucks were constantly coming laden with earth, which was tipped on to the lower ground, forming an embankment, which gradually came nearer and nearer the river bank. Down by the river bank, on the far side, and on the near side as well, were men digging for weeks at a time. Then, these made way for an army of brick layers and masons, and loads and loads of brick and stone were brought along the line, or dragged by horses through the old country lanes to the waterside. There, on each side of the stream, what looked like big towers were erected, as tall as the church tower, or taller perhaps, and still the earth day by day was being brought along the way and tipped, adding to the embankment yard by yard. Such earth, too; clay, perhaps, or earth of such kind as the oldest man in the parish had never seen in those parts before, because it had been brought from a place or places many miles away.
Then, when the brickwork on each side of the river was in position, there was the building of a bridge to watch. There were several huge arches of brick, or perhaps of stone, brought from far-off quarries. But what were those queer, lattice-work things, looking something like spiders' webs, which were brought down to the waterside? There was nothing like that ever seen in the village before. What did it mean? They saw these great iron lattice-work sections hoisted in the air by steam cranes and swung slowly up and round till they were placed in position, resting on the piers of masonry. It must have been a wonderful sight to watch the river being spanned by a huge bridge or by these girders, and to see the different sections being fitted and fastened together.
You may be sure that there was much shaking of heads and many prophecies that this sort of thing was a flying in the face of Providence—just as in our own time there has been over cycles, motor-cars, and air-craft. How could those great trains and heavy engines pass safely over such a flimsy-looking bridge as that? It would be sure to snap in the middle. And when an accident happened—and sad accidents did happen—many declared that it was the Almighty's judgment upon men for thinking that they knew better than their fathers before them.

So the work went on, and in time the railway became an accomplished fact and was no longer a wonder, and a race grew up to whom railways became part and parcel of everyday life.
But the railways brought many other changes. Those loads of earth brought from distant parts of the line not only altered the appearance of the country where they were deposited, but caused other alterations as well. Grass soon grew on the slopes of these embankments, but with the grass came up also strange weeds and plants. These seeded, the wind scattered the seeds, and, in the fields on either side of the line, these new weeds showed themselves the next season. For a year or two, probably, nobody noticed this very particularly; but, before very long, whole districts might be overrun with varieties of weeds never seen in that district before.
In some places marshes had to be drained, and, in consequence, many broad, shallow stretches of water disappeared. Such "sedgy pools" in quiet districts were once the haunt of many varieties of wild fowl. As the pools have disappeared the wild fowl which made these their haunt disappeared also, and with them the wild flowers and water-plants belonging thereto have died out as well. In much the same way insects have been imported in the loads of earth and found a home in a new district where they have, so to speak, "settled", and have done in some cases good, and in other cases harm, to the land.
Many cuttings through the beds of gravel and rocks have taught us something of the changes which have taken place in the earth's crust. It has been possible to examine the structure of the soil of many parts of England more thoroughly in the deep railway cuttings and tunnels than could have been done in any other way. Geologists have gathered much most valuable information from the soil and rock dug out in railway excavations.
