This engine was severely tested, and worked without accident throughout the day, the seventeenth trial lasting no less than 63 minutes, during which the steam and water were both kept to a pressure of 90 lbs. on the square inch throughout, working through a 1-3/8 inch nose-pipe. At the eighteenth and last trial this engine threw a good vertical jet. Messrs. Shand and Mason's small engine did not raise the steam to 100 lbs. in less than 30 minutes, owing, of course, partly to the mismanagement already mentioned, and partly to the nature of the boiler and fire-box, which, according to the makers' account, are not adapted for raising steam in the shortest possible time. After the engine got to work the steam-pressure was well sustained, and the engine continued working the entire day without accident, concluding in the evening by throwing a good vertical jet. During the time occupied by the trials the direction of the wind was W.N.W. to W. by N., pressure 2-1/2 to 4-1/2 lbs. on the square foot. The barometer stood at 29.97 inches. _Summary._ On the whole the Committee find as follows:-- Messrs. Merryweather and Son have produced, at a price of 700_l._, a steam fire-engine, weighing, according to the makers' account, 65 cwt., with jets and lamps, but without water, coal, suction-pipes, hose, or other gear, and capable, if no accidents occur, of throwing in an available stream the following average quantities of water per minute:-- Distance. Angle. Quantity. 61 feet. 10 deg. 230 gallons. 85 " 21 deg. 124 " Messrs. Shand and Mason have produced an engine, at a cost of 650_l._, weighing, according to their statement, 55 cwt., with jets and lamps, but without water, coals, suction-pipes, hose, or other gear, and capable of throwing in an available stream the following average quantities of water per minute:-- Distance. Angle. Quantity. 61 feet. 10 deg. 250 gallons. 63 " 18 deg. 165 " 82 " 14 deg. 172 " 85 " 21 deg. 137 " 102 " 11 deg. 94 " 104 " 17 deg. 19 " Messrs. Shand and Mason have also produced, at a price of 370_l._, an engine which, under the same conditions, weighs 35 cwt., and is capable of throwing in an available stream the following average quantities per minute:-- Distance. Angle. Quantity. 61 feet. 10 deg. 142 gallons. 63 " 18 deg. 133 " 82 " 14 deg. 56 " 85 " 21 deg. 27 " The best performance during the five trials from which this last average was taken being forty-six gallons, and the lowest five gallons per minute.
