ON STEAM NAVIGATION AT HULL. 121 



low, Lumsden and Co., under the direction of Mr. Anderson their engineer, 

 exhibits the great advantage gained by the alteration. Her register tonnage 

 is 690, and the total tonnage 1014.. She was formerly fitted with steeple 

 engines of 350 horse-power, and had four boilers, two before and two abaft 

 the engines; but these were substituted by direct action engines of 150 

 horse-power, and two of her old boilers replaced, and by this alteration a 

 clear length of hold in midships of 23 feet is gained. She required before 

 the conversion 650 tons of coals for a Petersburg voyage, and consumed 30 

 to 40 cwt. per hour, but now 350 tons for the voyage, and a consumption of 

 20 cwt. per hour. By the change of machinery about 130 tons of dead weight 

 is removed from the ship, and she is now able to carry 400 tons more cargo. 

 Her speed is also improved considerably ; for before the alteration, when 

 drawing on an average about 14 feet, the rate was 6^ knots; but since the 

 change, when drawing even more water, they can steam 8 knots. Thus 

 throughout a saving almost in all the departments of the ship, and other ad- 

 vantages have been effected in this important change. 



During the last two years many fine steam-ships have been built in Hull, 

 and others are in process of building for English and foreign service, by 

 Messrs. Brownlow, Lumsden and Co., Messrs. C. and W. Earle, and Messrs. 

 Martin, Samuelson and Co. 



The last-named firm are making rapid progress in the building of two large 

 iron paddle steam-ships, for the Atlantic Royal Mail Steam Navigation Com- 

 pany, of the following dimensions, power, &c. : — 



feet. 



Length between the perpendiculars 360 



Beam, moulded 40 



Depth 30 



Tonnage, builders' measure 2860 



Nominal horse-power 800 



These ships are to have three decks, and to be fitted fore and aft for pas- 

 sengers. Speed through the water 20 miles per hour. They will be of im- 

 mense strength, and their build and form such as to ensure their becoming 

 fine sea-boats. 



Since the Meeting of the British Association at Dublin, considerable ad- 

 vance has been made in London and other ports in the application of super- 

 heated steam, and I believe with great success and satisfaction in the results. 



Hull, however, is acting on the motto Festina lenie, and before taking a de- 

 cided step in this important discovery, is anxious to see and adopt the best mode 

 of the application of the principle, being assured that, in every onward move- 

 ment, it is better to " make no more haste than good speed." Some attention 

 has been paid to the consumption of smoke in the furnaces of our steam-
