[August, 



in the first p sition, in order lo receive a fresh supply of rompresscd air and 

 nater, to set the piston in the I;irge cylinder again in mution, which com- 

 municates i's power to a pump or engrine. 



The •' £clij!se.'' — A new iron steam-boat has just been completed by Messrs. 

 John and 1-rancis Napier, of Mill-uall, said to be decidedly the fastest 

 steamer in Knf;land. She lias niiide sevcr.il experimenlal trips up and down 

 the river, and from her surprising sjiecd and singu'ar app-arance (having 

 two funnels and the piston cross-lu-ad working above the dccli) a report has 

 (jot ahror.d that she is driven by high piessnre steam This, however, i^ in- 

 correct : she is propelled hy one enginr of 100 horse power, the cylinder is 

 54i inches di.-imeter. with four feet stroke : she has a double bottom, which 

 gives increased strength and safety, and at the same time allords a large 

 space wherein the steam is conveniently condensed, which keeps up a regular 

 supply of fresh water to the boilers, saving nearly the entire power of work- 

 ing .an air-pump, i^he has tour separate boilers, any three of which are 

 adequate to supply the engine; so that one may be repaired. See, without 

 causing any delay. The makers have met the report of " liisiU-pressure steam " 

 being used, by aii ofier to run the Erli/jse, against any steamer afloat, for any 

 distance under 500 miles, with steam at a lower pressure than tliat of her op- 

 ponent! — Mecli. Mug. 



New mode of propelling Slenm Bonis. — Falkirk, July 7. — An ingenious me- 

 chanic, residing at Gr hamstone. has been for a long period engaged in con- 

 structing a small vessel to be propelled by means of pressure-pumps — the 

 application of a principle (juite new to the masters of this science. On Mon- 

 day evening the boat was launched into the Forth and Clyde canal, at Bains- 

 ford-bridge, and proceeded beautifully along the reach at a rate of not less 

 than 15 miles per hi.ur. conducted alone by the inventor, who worked the 

 pumps. This novel invention has produced much speculation am-ng the 

 members of the proiession in this place, and it is now reported tliat he is so 

 much satisfied with his first experiment, that another on a larger scale is 

 fortlmith to be undertaken, and a patent procured to protect the invention. 

 He has no doubt that it will, at no distant era. entirely supersede the present 

 mode of propulsion by means of paddle-wheels. — Times.
