ne who had seen it, but he knew the name of the inventor. In 1709, Gusman, a Portuguese monk, constructed a machine in the form of a bird. He was pensioned for this, and was thus perhaps enabled to rise in the world, which his machine signally failed to do. Not discouraged, however, in 1736 he constructed a wicker basket covered with paper, which rose to the hight of 200 feet in the air, by which he gained at least fame, if not money, for he was afterwards reputed a sorcerer. It was in 1783 that the Montgolfiers discovered that the lesser specific gravity of heated air created an ascensive force by which heavy objects might be raised through the atmosphere; and in less than a month afterwards hydrogen gas, which had then been known for about seventeen years, was successfully employed in a balloon for the same purpose. This seemed to render the idea of aerial navigation more feasible, and accordingly Blanchard, one of the earliest aeronauts, on his first ascent from Paris in M

ilago, simila, flos, pollen, cibarium. Two other plans may be noticed; one which produces what is called entire wheat flour, the bran being ground to an impalpable powder and mixed with the flour. Also a French plan, in which grinding is dispensed with; the wheat being decorticated, macerated, and crushed by rollers into a dough fit for baking. The first steam flouring-mill in England, perhaps in the world, was the Albion, erected at the Southwark end of Blackfriars' Bridge, London, in 1783. The best-appointed grinding-mill in England is said to be the City FlourMill of London. Its capacity and arrangement are thus described by Mr. Tomlinson : — The mill, which is fire-proof, is 260 feet in length and 60 in width. There are thirty-two pairs of stones all furnished with the blowing-apparatus, the runner of each pair being worked by a strap. A long horizontal trunk placed above the millstones is supplied with condensed air by means of a powerful fan. From this trunk pr

ntroduction of the steam-engine, which increased the power of the blast, and the blowing engines driven by manual, horse, or ox power were superseded by engines. The dimension of the blast apparatus was increased from time to time, and about 1760 coke was commonly used in blast-furnaces. In 1760 Smeaton erected at the Carron works the first large blowing cylinders, and shortly after Boulton and Watt supplied the steam-engines by which the blowers were driven. Peter Onions, in his patent of 1783, described the rationale of the puddling process; and Henry Cort, of Gosport, in 1784, made it practicable, and added grooved rolls, by which the puddled bar was drawn. Neilson, of Glasgow, introduced the hot blast in 1828. Aubulot, in France, in 1811, and Budd, in England, in 1845, heated the blast by the escaping hot gases of the blast-furnace. The Calder works, in 1831, demonstrated the needlessness of coking when hot blast is employed. Experiments in smelting with anthracite coal we

or 1732; Georgia gazette, 1763. The first paper in New Hampshire was published in 1756, but in the adjacent State of Vermont none existed prior to 1781. After the Revolution, the history of newspaper progress becomes identical with that of the nation, the printing-press keeping closely in the van of Anglo-American civilization. The honor of publishing the first paper west of the Alleghanies is claimed for John Scull of Pittsburgh, who, it is stated, founded the Pittsburgh gazette in 1783. The first north of the Ohio River, being the third or fourth west of the Alleghanies, is said to have been the Centinel of the Northwest territory, by William Maxwell, 1793. According to De Saint Foix, the earliest French newspaper, called the Gazette de France, was established by Renaudot, a physician, who obtained a royal grant of the exclusive privilege of publishing the same for himself and family. He had previously been in the habit of collecting information and circulating news-

describes a machine of this kind used in descending hights. It was not employed in Europe till 1783, when M. le Normand proved its efficacy by letting himself from the windows of a lofty house in the first, or roughing, rolls of a rolling-mill. Invented by Henry Cort, England, and patented in 1783. The loop, or ball of puddled iron, after a preliminary forging, is drawn out by passing throuhe loop is drawn out into bars, instead of being extended under the hammer; this Cort patented in 1783. In each case Cort does not seem to have been the first inventor, though he was the most succeount, were made to his descendants, even as late as 1856. The puddle-rolls patented by Cort in 1783 are described in Payne's patent, 1728. The process of puddling iron in a reverberating furnace described in the specification of the Brothers Cranage, 1766, and the furnace in Onion's patent, 1783.

ich are either plane or grooved to suit the shape to be imparted. The grooved rolls are the invention of Henry Cort, in 1783. Iron, steel, and copper are rolled while red-hot, but most other metals and alloys are rolled cold; in most instances reto assume a direction longitudinal of the bar, some extraneous matters being also removed in the operation. In the year 1783, Henry Cort, of Gosport, England, received an English patent for the rolling of iron, as a substitute for hammering. Durirmingham theater, England. Iron roofs were first used in England, and were the subject of a patent by Robert Ransome, 1783. They are composed of essentially the same members as those of timber, malleable rods or flat bars Roof of the Pancrngland, and effected a great improvement in the manufacture of cables and cordage.

n ship's bottom from worms. Lead was used for the purpose nearly as long ago as the Christian era. The gradual oxidation of the copper has been prevented by the application of pieces of zinc or iron upon different parts of the surface. This renders the copper electro-negative and preserves it, but at the expense of its cleanliness, as marine weeds and barnacles are more apt to adhere to it. The order for the sheathing of the vessels of the English navy with copper-plate was given in 1783. Sheathing-copper is laid on with a lap-joint, the lower and after edges of the sheet lapping upon the sheets below and abaft it. The grades are known by the number of ounces to the superficial foot, as 16-ounce, 18-ounce, 28-ounce, 32-ounce. The heaviest is put forward from the bows to the keel, and on the load-line and four strakes below it. The sizes of these metallic sheets are as follows:— Weight in ounces per square foot182832 Thickness in inches0.0250.0380.044 Length in inc
