duced into France from Persia, in the reign of Henry IV., about 1606; a manufactory being established at Chaillot, near Paris. Workmen from France introduced carpet-making into England about 1750. A carpet-factory was established at Axminster, 1755, the year of the Lisbon earthquake. There are several characteristic processes in the manufacture of carpets. 1. The web is formed of a warp and weft of flax, and the wool or worsted is inserted in tufts which are twisted around each of the Harrison, born in 1693 at Faulby, near Pontefract, in England, undertook the task, and succeeded after repeated attempts, covering the period 1728 – 1761. His first timepiece was made in 1735; the second in 1739; the third in 1749; the fourth in 1755, the year of the great earthquake at Lisbon. In 1758 his instrument was sent in a king's ship to Jamaica, which it reached 5″ slow. On the return to Portsmouth, after a five months absence, it was 1′ 5″ wrong, showing an error of eighteen miles

speedily enters into ebullition; but, unless the machine is kept constantly in action, the vapor which is thus formed will restore very promptly the pressure upon the surface which has been removed by the exhaustion. If, however, the pump be powerful enough to carry off the vapor as fast as it is formed, and be steadily worked, the heat which the rising vapor withdraws from the water will presently reduce the temperature to the freezing-point, and the liquid will be converted into ice. In 1755, Dr. Cullen discovered that removing the pressure of air facilitated evaporation to a degree which enabled him to freeze water even in summer. In 1777, Mr. Nairne discovered that introducing sulphuric acid into an exhausted receiver absorbed an aqueous vapor from and thereby dried rarefied air; and by an arrangement on these principles, in 1810, by which he got rid of the vapor that rose from the water, he prevented its forming a permanent atmosphere, so as to prevent the continuance of t

eacons were erected to direct navigation, and persons were appointed to keep them in order. The expense was defrayed by the county. Pitch boxes were made use of in the reign of Edward III. Lighthouses. The Eddystone lighthouse (b) is erected upon a rock of that name ten miles from shore, off Plymouth, England. A lighthouse was built on the spot, 1696-99, by Winstanley, who perished with it in a storm, November 27, 1703. Rebuilt of wood in a different form by Rudyard, 1706, and burnt 1755. Rebuilt by Smcaton of dovetailed and metal-bound granite blocks, 1757. The surface of the rock was irregular and inclined. It was cut into steps, the risers of which were notched so as to form dovetailed mortises for the similarly shaped blocks of the stones in the course which interlocked with it. Each block had a level bearing, and the outside pieces were guarded by a border of rock which rose around them. The stones in a course were dovetailed together and additionally secured by cr

me crooked, requiring the services of a large number of workmen to straighten them. These being thrown out of employment by the new process made a riot and drove its introducer out of town, but it was finally generally adopted. A similar disturbance had taken place in 1830, on the introduction of the stamping-machine. The machine for pointing is of still more recent introduction. A needle with a point at each end and an eye at the middle of its length was patented in England in the year 1755, for hand-sewing or embroidering, the patentee describing it as used by holding it with the fingers at the middle of its length, so that it will not require turning. In 1829 it was successfully introduced into an embroidering-machine, which is still in extensive use. As many as one hundred and thirty such needles, worked by pincers on opposite sides of the fabric to be embroidered, are used in a single machine. In 1842 a sewing-machine inventor adopted the same kind of needle, and some othe

The hammer-harpsichord, so called from the substitution of hammers for plectra, was the first pianompe made large numbers in England, 1766, and following years.

being interwoven by another thread below. d. Those making the lock-stitch, the same on both sides. The last is the latest and best. See also infra, sewing-machine (for books), page 2119, and shoe-sewing machine, Plate LIX. a. The stitch made by passing the needle completely through the goods, in the manner of hand-sewing, was the first performed by machinery. Such are classed as short-thread machines. The needle with two points and an eye at midlength was patented in England in 1755. The embroidering-machine of Heilmann, patented (to Bock) in England, May 2, 1829, No. 5,788. for that purpose, was for a machine in which a large number of needles, each with an eye in the middle and a point at each end, or tambour-needles, are simultaneously actuated over a moving web of cloth, so as to repeat the patterns at various points from one governing design and on a more minute scale if desired.

were no less than five such waves, each of increasing force, and an hour and a half after their commencement the waves still ran to a hight of forty feet above their usual level. At Iquique, a single wave some 50 feet in hight, after submerging an island lying in front of the town, and rushing far inland, soon resumed its usual condition. Similar effects have been frequently noted in connection with earthquakes. Among the most remarkable was that which occurred at the great earthquake in 1755, so destructive at Lisbon, where an immense wall of water many feet in hight was observed to come rolling inward from the Atlantic, breaking with irresistible force upon the shore and carrying every thing before it. The frequent earthquakes which have devastated the Pacific coast of South America, lying at the base of the Peruvian and Chilian Andes, have been accompanied by the same phenomenon. These waves, far exceeding in hight the ordinary waves of the sea, and still more the great tidal
