The statement, often repeated on high authority, that the pyramids were built before the Egyptians acquired the art of writing hieroglyphics, however, which they do contain, do not convey that full knowledge of the state of the arts among them, at the time the pyramids were constructed, which is to be learned from the writings and pictures in their tombs and temples, in regard to the state of their arts at a subsequent period. But we have the less valuable authority of Herodotus that the blocks of stones were lifted from one course to the other up the steps of the pyramid. Remains of Cheops’ grand causeway, for transporting the blocks quarried from the rocks on the east bank, are still seen leading up the great pyramid from the plain, a shapeless ridge of ruinous masonry and sand. According to Herodotus, it was one thousand yards long, sixty feet wide, and forty-eight feet high, was adorned with figures of animals, and was a work of ten years. Some of the stone used for the coping over the passages are seven feet thick and more than seventeen feet long. Lifting these stones up the side of a pyramid four hundred and fifty feet high was certainly a work of great labor; but as a feat of engineering it was mere child’s play compared with some of the triumphs of modern science and skill,—for instance, lifting the Menai bridge on to its piers, or raising on end and placing on its pedestal the monstrous monolith which adorns the city of St. Petersburg.
RAILROADS FROM 1760—ENGLAND.
In 1760, wooden railroads were in pretty general use to facilitate mining operations. Tram-roads, with rails of cast iron, first introduced at the Colebrookdale Works, at the instance of Mr. Reynolds in 1767; at the Sheffield colliery in 1776. Stone props for the support of the rails substituted for timber in 1797, at Newcastle-upon-Tyne. Edge rails were brought into use by Mr. Jessop in 1789, at Loughborough. Malleable iron edge rails adopted at Newcastle in 1805, and at Tinsdale Fell in 1808. The improved malleable edge rail now in use was invented by Mr. Birkinsaw in 1820. A locomotive engine propelled by steam was employed for the first time on the Merthyr-Tydvil Railroad in Wales in 1804. Blenkinsop’s locomotive engine, which operated by means of cog-wheels and rack rails, was invented and applied on the Leeds Railroad in 1811. But the locomotive engine that has obtained the greatest reputation and been most generally adopted was that invented by Mr. George Stevenson in 1814. This engine has undergone a variety of improvements up to 1829, and was deemed at that period more efficient than any of its predecessors.
RAILROADS IN THE UNITED STATES.
(Abstract of the Seventh Census.)
In no other particular can the prosperity of a country be more strikingly manifested than by the perfection of its roads and other means of internal communication. The system of railroads, canals, turnpikes, post-routes, river navigation, and telegraphs possessed by the United States presents an indication of its advancement in power and civilization more wonderful than any other feature of its progress. In truth, our country in this respect occupies the first place among the nations of the world.
From returns received at this office in reply to special circulars, and other sources of information, it is ascertained that there were, at the commencement of the year 1852, 10,814 miles of railroads completed and in use, and that 10,898 miles were then in course of construction, with a prospect of being speedily brought into use. While the whole of these 10,898 miles will, beyond reasonable doubt, have been finished within five years, such is the activity with which projects for works of this character are brought forward and carried into effect, that it is not extravagant to assume that there will be completed within the limits of the United States before the year 1860 at least 35,000 miles of railroads.
The Quincy Railroad, for the transportation of granite from the quarries at Quincy to Neponset River, and the Mauch Chunk Railroad, from the coal-mines to the Lehigh River, in Pennsylvania, were the first attempts to introduce that mode of transportation in this country; and their construction and opening, in the years 1826 and 1827, are properly considered the commencement of the American railroad system. From this period until about the year 1848, the progress of the improvements thus begun was interrupted only by the financial revulsion which followed the events of 1836 and 1837. Up to 1848, it is stated that about 6000 miles had been finished. Since that date an addition of 5000 miles has been made to the completed roads, and, including the present year, new lines, comprising about 14,000 miles, have been undertaken, surveyed, and mostly placed under contract.
The usefulness and comparative economy of railroads as channels of commerce and travel have become so evident that they have in some measure superseded canals, and are likely to detract seriously from the importance of navigable rivers for like purposes. In a new country like ours many items of expense which go to swell the cost of railroads in England and on the continent are avoided. Material is cheap, the right of way usually freely granted, and heavy land damages seldom interpose to retard the progress of an important work. It is difficult to arrive at a clear approximation to the average cost of railroad construction in the United States. Probably the first important work of this class undertaken and carried through in the Union was the cheapest, as it has proved one of the most profitable, ever built. This was the road from Charleston, in South Carolina, to Augusta, on the Savannah River. It was finished and opened for traffic in 1833. The entire expense of building the road and equipping it with engines and cars for passengers and freight was, at the date of its completion, only $6700 per mile; and all expenditures for repairs and improvements, during the eighteen years that the road has been in operation, have raised the aggregate cost of the whole work to only $1,336,615, or less than $10,000 per mile.
