. Lloyd's steamboat directory, and disasters on the western waters . at in the ladiescabin, were destroyed. Capt. J. V. Throop, the commander of the Lexington, has been en-gaged on the river for twenty-five years. He is a prudent and ex-perienced officer, and this is the first accident that ever befel a boatunder his command. THE END. PALMERS GREAT MARINE PUMP. We have seen all kinds of Marine pumps in operation, have knoYn some of thesepumps to throw ten thousand j^allons of water per minute and raise sunken vesselsin five and sis hours, but we have seen a pump in operation that eclipses them allin rc2;ard to utility and power, we mean Palmers Marine Pump, justly entitledto the name of the Invincible. Palmers Marine Pump is constructed on anentire new principle, combining the most simple and gigantic means for raisingsunken vessels. This great Marine Pump was patented July, 1855. It consistsof a wheel chamber between tliree and four feet in diameter, with a suction anddischarge pipe attached, all of cast iron. The latter is eighteen and a half inclv-. palmers marine pump as worked ey hand.in diameter. In the chamber is a perpendicular screw wheel, which, when in ope-ration, isTOade rapidly to revolve, and thus on the principles of reaction and ai-mospheric pressure, the water is raised and discharged at the rate of seventeenthousand gallons per minute, rendering it almost impossible for a steamboat or shipto sink tchile one of these tremendotis pumps is in operation. Had tlie ill-fated steam-ship Arctic been supplied with Palmers Marine Pumps at the time of her colli-sion, she would never have ffone to the bottom of the Atlantic, hurrying into eternitythree hundred souls. For wrecking purposes, an engine of five or six horse power is used, and as thereare to valves to Palmers Marine Pump, it is so constructed that sand, grain, cof-fee, dried fruit, or any article of like nature, cannot choke it up and impede itsrapid operations. The Pump is not cumbersome, but can
