The workmansliip of this engine was good ; working parts firm, 

 and strong-fitted ; complete ; with mercury-gauge, and an ad- 

 ditional safety-valve placed out of the control of the engineman, 

 thereby giving greater safety. The boiler was tubular, but 

 formed of two sets of tubes, the one direct, the other returning 

 the smoke from the smoke-box to the chimney placed in front of 

 the boiler. This arrangement caused a great deficiency in the 

 draft, so that combustion of the fuel proceeded very slowly, and 

 consequent upon this, the time used in getting up steam, namely, 

 92 minutes, was too long to be good in practice, and the effective 

 duty performed by the engine showed a corresponding result."

"A 6-horse patented portable engine, manufactured by the 

 patentees, Messrs. Garrett and Son. The boiler of this engine 

 was formed with two direct side flues and one return circular 

 flue, the chimney being over the fire-box, and was the only flue- 

 boiler exhibited, which makes it interesting to notice, that with a 

 good draft and capability of burning an inferior description of 

 fuel, the duty done was equal to several of the tubular boilers, 

 while the price is less. The workmanship of this engine was 

 good, working parts firm, strong, and well fitted, with mercury 

 ami water-gauges and governors well adjusted. The force- 

 pump is fitted with a tap so constructed as to return a portion 

 of water back to the cistern when the boiler is sufficiently sup- 

 plied, thereby rendering the bursting of the joints through the 

 carelessness of the attendant, impossible. This engine was 

 mounted on strong wooden wheels very suitable to farmi roads."

'' A 6-horse portable engine, also manufactured by Messrs. 

 Garrett and Son. The general remarks made upon their 

 former engine are also equally applicable to this as respects 

 workmanship and strength; it is also fitted with the necessary 

 steam and water-gauges and governors, and we would espe- 

 cially notice the strength and construction of the one carriage 

 of the four bearings of the crank-shaft, admitting of their being 

 bored out at one operation in the lathe. The boiler of this engine 

 is tubular, but the fire-box circular, the outer case being an uni- 

 form cylinder throughout, thereby attaining great strength and 

 durability, points so essential to be noticed in engines to be worked 

 by unexperienced hands ; the plates of this boiler were -|, and tube- 

 plate |-inch thick, showing much greater strength than in the one 

 which obtained the second prize. The duty performed by this 

 engine was very satisfactory, as will be seen by refereuce to the 

 tabular statement : and if we make due allowance for a cold rain 

 falling during the whole of //i25 trial , the other engines having the
