Snidll portable Fire Engine. 



.R. HORBLOWER, of Featherstone Street, City Road, 

 with whose talents the world is well acquainted, has re- 

 quested me to mention a construction of the fire engine which 

 he has made, which renders it of much utility within the 

 apartments of an house. 1 have not seen the engine j but he 

 .states, that it stands in the compass of fourteen inches square 

 and two feet high, and may be carried from one room to 

 another with ease. He finds, by experiment, that the four 

 sides of a bed-room, all on fire, may he extinguished in the 

 space of a minute, by little more than a pail of water. All 

 that is required is to keep it filled in its proper place, and to 

 work it off every month or six weeks, for the purpose of 

 changing the water and ascertaining that it is in proper work- 

 incf state. 



EnquirT/ respecting Grease Spots. 



A Correspondent requests to be informed of a method of 

 discharging grease spots from coloured goods, composed of 

 silk and worsted. He observes, that it frequently, happens, 

 in the process of weaving, that the tallow or oil drops on the 

 work from the candles or lamps used by the weavers, and 

 forms spots which render the goods quite unsaleable ; and he 

 suggests, that if any of the readers of this Journal should point 

 out a method of discharging them, they would render a cop.- 

 aiderable service to manufacturers. 



I wish it were in my power to point out the remedy here 

 desired from actual experiment ; but I must leave the answer 

 to othersj and shall only Venture to speak in general terms of
