Brayley in his History of Surrey says, "Besides this Mansion (near York House) there are several handsome seats fronting the river and various large manufacturing establishments, Chemical works, and melting furnaces, etc. are extensive along its banks, greatly to the annoyance of the market gardeners and florists who complain grievously of the injury they sustain by the smoke and noxious vapours of the numerous steam engines now employed in this hitherto rural district. The establishment here for the preservation of timber from the dry rot, called _Kyanizing_ from the name of its inventor, was destroyed by fire on the 20th of March, 1847; and the conflagration extended to other neighbouring works. The process was carried on by forcing tar through the pores of the wood, and here was a large pond of that fluid, the blaze of which set fire to immense piles of timber which had either undergone the process, or were in a state of preparation for it."--_Brayley, Surrey Mantel_, _Vol. iii. P._ 447. A very useful thing is that dentated instrument called the _Saw_. Pliny says that the saw was invented by Dædalus. According to Apollodolus Talus invented the saw. Talus it is said having found the jaw-bone of a snake employed it to cut through a piece of wood and then formed an instrument of iron like it. Saw-mills were erected in Madeira in 1420. At Bresdan in 1427. Norway had the first saw-mills in 1530. The Bishop of Ely Ambassador from Mary of England in the escort of Rome describes a saw-mill there 1555. The attempts to introduce saw-mills into England were violently opposed, and one invented by a Dutchman in 1663 was forced to be abandoned. Saw-mills were erected near London about 1770. The excellent saw machinery at Woolwich Dockyard is based upon the invention of the Elder Brunel, 1806-13. Sir Mark Isambard Brunel was the son of a Normandy farmer, and born at Hacqueville, near Rouen, on the 25th of April, 1769. He early shewed an inclination for mechanics, and at school preferred the study of the exact sciences to the classics. In 1786, he became a sailor in the French Navy. In the revolutionary period of 1793, having involved himself by his political opinions he escaped from Paris to the United States. Brunel's career as an engineer began 1794 when he was appointed to survey for the Canal which now connects Lake Champlain with the river Hudson, at Albany. He afterwards acted as an architect in New York. On his return to Europe in 1799, he married the daughter of William Kingdom, Esq., Plymouth, and settled in England. Here he soon established his reputation as a mechanician by the invention of a machine for making block pulleys for the rigging of ships. The erection of steam saw-mills in Chatham Dockyard, a machine for making seamless shoes for the army, machines for making nails and wooden boxes, for rolling paper and twisting cotton hanks, and lastly a machine for producing locomotion by means
