rsal use of rotary motion, and of the reduplication of parts. The steam-engine is a machine of reciprocating, converted into rotary, motion by the crank. The progress of mechanical engineering during the nineteenth century is measured by the improvements of the steam-engine, principally in the direction of saving fuel, by the invention of internal combustion or gas-engines, the application of electrical transmission, and, latest, the practical development of steam turbines by Parsons, Westinghouse, Delaval, Curtis, and others. In these a jet of steam impinges upon buckets set upon the circumference of a wheel. Their advantages are that their motion is rotary and not reciprocal. They can develop speed of from 5,000 to 30,000 revolutions per minute, while the highest ever attained by a reciprocating engine is not over 1,000. Their thermodynamic losses are less, hence they consume less steam and less fuel. Duplication of parts has lowered the cost of all products. Clothing is

sh Institution of Civil Engineers: Engineering is the art of controlling the great powers of nature for the use and convenience of man. The seed sown by Bacon was long in producing fruit. Until the laws of nature were better known, there could be no practical application of them. Towards the end of the eighteenth century a great intellectual revival took place. In literature appeared Voltaire, Rousseau, Kant, Hume, and Goethe. In pure science there came Laplace, Cavendish, Lavoisier, Linnaeus, Berzelius, Priestley, Count Rumford, James Watt, and Dr. Franklin. The last three were among the earliest to bring about a union of pure and applied science. Franklin immediately applied his discovery that frictional electricity and lightning were the same to the protection of buildings by lightning-rods.

entury. The only radical advance is the use of a better steel than could be had in earlier days. Steel-arched bridges are now scientifically designed. Such are the new Niagara Bridge, of 840-foot span, and the Alexandra Bridge at Paris. That which marks more clearly than anything else the great advance in American bridge building, during the last forty years, is the reconstruction of the famous Victoria Bridge, over the St. Lawrence, above Montreal. This bridge was designed by Robert Stephenson, and the stone piers are a monument to his engineering skill. For forty winters they have resisted the great fields of ice borne by a rapid current. Their dimensions were so liberal that the new bridge was put upon them, although four times as wide as the old one. The superstructure was originally made of plate-iron tubes, reinforced by tees and angles, similar to Stephenson's Menai Straits Bridge. There are twenty-two spans of 240 feet each, and a central one of 330 feet. I

When Dalton first applied mathematics to chemistry and made it quantitative, he gave the key which led to the discoveries of Cavendish, Gay-Lussac, Berzelius, Liebig, and others. This new knowledge was not locked up, but at once given to the world, and made use of. Its first application on a large scale was made by Napoleon in encouraging the manufacture of sugar from beets. known, there could be no practical application of them.

odern times that the reign of law was greatly extended, and men were insured the product of their labors. Then came the union of scientists, inventors, and engineers. So long as these three classes worked separately but little was done. There was an antagonism between them. Ancient writers went so far as to say that the invention of the arch and of the potter's wheel were beneath the dignity of a philosopher. One of the first great men to take a different view was Francis Bacon. Macaulay, in his famous essay, quotes him as saying: Philosophy is the relief of man's estate, and the endowment of the human race with new powers; increasing their pleasures and mitigating their sufferings. These noble words seem to anticipate the famous definition of civil engineering, embodied by Telford in the charter of the British Institution of Civil Engineers: Engineering is the art of controlling the great powers of nature for the use and convenience of man.

i itself to the Gulf of Mexico, is a logical sequence of the first project. The Nicaragua Canal would then form one part of a great line of navigation, by which the products of the interior of the continent could reach either the Atlantic or Pacific Ocean. The cost would be small compared with the resulting benefits, and some day this navigation will be built by the government of the United States. The deepening of the Southwest Pass of the Mississippi River from 6 to 30 feet by James B. Eads was a great engineering achievement. It was the first application of the jetty system on a large scale. This is merely confining the flow of a river, and thus increasing its velocity so that it secures a deeper channel for itself. The improvement of harbors follows closely the increased size of ocean and lake vessels. The approach to New York Harbor is now being deepened to 40 feet, a thing impossible to be done without the largest application of steam machinery in a suction dredge
