pump for raising water, we consider it superior to any heretofore 

 in use ; for ships' purposes, we believe it would be found extremely 

 valuable ; for extinguishing fires it may be used to great advan- 

 tage, and it may be esteemed as an important appendage in 

 factories, stores, public buildings, gardens, &c. 



These pumps may be obtained at prices varying from $35 to 

 |1,400, depending on size and materials. Those costing the low- 

 est sum will raise 30 gallons per minute at 120 revolutions. 

 The Institute awarded to the inventor its gold medal in 1851. 



ICE MARKER AND CUTTER. 



Ic€ has now become an almost indispensable article in our 

 domestic economy, consequently every invention which facilitates 

 the acquisition of it, is of interest. 



Messrs. J. k D. Ascough & Co., exhibited at our late fair two 

 instruments which are used with great effect in procuring ice 

 during the period when it is laid up for use through the warm 

 season when it is most required, or for transhipment. These 

 instruments are denominated as a Marker and Cutter, and are 

 constructed thus : the frame work, which is made of wood, re- 

 sembles the beam and handles of an ordinary plough, with the 

 handles permanently attached to the beam. On the under side 

 of the beam, extending the greater part of its length there are 

 fixed a series of cutters made of steel and placed in succession, 

 gradually extending deeper from the front to the rear of the 

 beam, the longest being about 4 inches ; this instrument is used 

 as a marker, cuts about two inches deep, and with the services of 

 one horse and a man will mark off from 1000 to 1,500 tons of ice 

 in 10 hours. The cutter is similarly formed, except that the 

 cutting instruments are made to cut much deeper, say from 8 to 

 12 inches. This also is operated by one horse and a man, and 

 follows in the small furrow made by the marker, and will cut 

 from 500 to 750 tons in 10 hours; thus it requires two cutters to 

 complete the work of one marker, and together they will accom- 

 plish the work of 75 men with saws, which has been the usual 

 mode of cutting ice in use heretofore. A. C.
