The Pot (Maine, United States) (search for this): chapter 19
t part of the East River known as Hellgate so dangerous to navigation in Long Island Sound. The principal of these were Pot Rock, on which the British frigate Hussar was wrecked at the close of the Revolutionary War, occasioning the loss of many livaken by Maillefert in 1851. Under an agreement with the New York Chamber of Commerce, this engineer undertook to remove Pot Rock, the Frying Pan, and Way's Reef for the sum of $15,000. The first of these, shown in profile at a, was, at its highesas made August 19, 1851, and was perfectly successful, knocking off about 4 feet from the highest projecting pinnacle of Pot Rock. Operations were continued on this and other obstructions until March 26, 1852, when three men were killed by an explos of the battery connections. During this period 284 charges, containing in all 34,231 pounds of powder were exploded on Pot Rock, reducing its level to 18 feet below low-water mark; and 240 charges, containing nearly 27,926 pounds, on Way's Reef an

Spin′ning-wheel. A machine consisting of a large wheel, band, and spindle, and driven by foot or by hand. The wool is carded into rolls, which are twisted, drawn, and wound a length at a time, the wheel being turned periodically to twist the yarn. It was the first great improvement upon spinning by a distaff and spindle. It appears to have been in use for many ages in Hindustan, but did not reach Europe before the sixteenth century. One account states that it was invented at Nuremberg about 1530: the statement is improbable. The accompanying cut is taken from an illuminated manuscript of the fourteenth century, in the British Museum (M. S. Reg. 10 E. IV.), and represents a lady spinning at her wheel. Spinning-wheel. The spindle is rotated in horizontal bearings, having a spool, over which the band from the larger wheel passes. A roving, being attached to the end of the spindle, is twisted as the latter revolves, the roving being allowed to slip between the

In the English service there were, until lately, sitain by Henry Anderson, who, about 1610, brought them from Stralsund, Pomerania, and was granted a patent for the privilege of running them between Edinburgh and Leith. Some fourteen or fifteen years afterward they had become known in England. In 1659 the Coventry coach is referred to, and in 1661 the Oxford coach, which took t

lowered, it and the disk e turn on the universal joint as a center, causing the disk f to rotate on its axis and around the disk e until the propeller assumes the desired position. Mr R. Griffiths, of London, well known in connection with propellers, has recently proposed to employ a screw placed within a tunnel both at the bow and stern; from trials with models he concludes that an increase of nearly 50 per cent in speed can be gained with the same power. A small boat employed at Burlington, Iowa, for crossing the Mississippi, 50 feet long 7 feet beam, drawing 30 inches aft and 1 foot forward, and propelled by a 4-foot propeller, attains a speed of 10 to 12 miles up stream, and 15 miles down stream.

alum, and saltpeter. The latter made gold potable, and no doubt induced the worthy Arabian to think that he was on the eve of the discovery of the transmutation of metals. To Rhazes, born A. D. 860, physician-in-chief to the great hospital at Bagdad, is due the credit of the discovery of absolute alcohol, which he obtained by distilling spirit of wine from quicklime. He also prepared sulphuric acid. Achild Bechil obtained phosphorus by the distillation together of urine, clay, lime, and Asia Minor at the head of 300,000 soldiers, and dictated a humiliating peace. About this time Charlemagne was subduing the Slavi of the Elbe and the Avars of Hungary. The king of the Franks at Aix-la-Chapelle received from the great Haroun of Bagdad presents, consisting of the keys of the holy sepulcher, a consecrated standard of Jerusalem, a wheelclock that struck the hours, an organ, an ape, and an elephant.

A hammer having a head of an oblately spheroidal form, with the handle in line of its axis. Stone bridge. Stone bridges appear to have originated among the Romans, who were the first to employ the arch on an extended scale. One with six arches, commenced by Augustus and finished by Tiberius, as its inscription indicates, still exists at Rimini. Others, some of which are yet in service, constructed by that remarkable people, are found, touched to a greater or less degree by the hand of time, in different parts of the former Roman Empire. Their stability, no doubt, was in great part due <

to Reading, and is situate in the heart of a coal country. It is 108 miles in length, and its construction cost about $2,500,000. This line of navigation is formed by 34 dams thrown across the stream, with 29 locks, which overcome a fall of 610 feet. It is navigated by boats from 50 to 60 tons burden. Slack-water navigation also occurs at intervals on many of the great lines of canals. About 78 miles of the Rideau Canal, in Canada, are formed in this way, and it is met with on the Erie, Oswego, Pennsylvania, Lycoming, and Lehigh Canals. The same mode is adopted on the river Severn in England, the dams being made of masonry. Slade. The sole of a plow. Slag. 1. (Metallurgy.) Vitreous mineral matter removed in the reduction of metals.
