The following measurements, kindly afforded to us from the books of the Navy Department, give the correct dimensions of the CHEREOKEE and MOHAWK, and will correct some errors we fell into, in our statement made hurriedly last week: The CHEREOKEE, Built at Kingston Dock Yard in 1842, under the superintendence of John Tucker, Esq. Fitted with two Engines of 100 horse power each, manufactured by Maudslay, Field & Son, London. Length between Perpendiculars, 170 feet: keel for tonnage, 150 feet 1 3/4 inches: extreme breadth, 30 feet 10 inches: breadth for tonnage, 30 feet 8 inches: breadth moulded, 30 feet: depth of hold, 16 feet 3 inches: diameter of cylinders, 53 1/2 inches: length of stroke, 5 feet: diameter of wheel, 22 feet 9 inches.
The MOHAWK, Built at Kingston Dock Yard in 1843, under the superintendence of Mr. Tucker.
gitted with two Engines of 30 horse power each, manufactured by the above makers.
Length between perpendiculars, 124 feet 3 in.: keel for tonnage, 112 feet 6 in.: extreme breadth, 19 feet 6 inches: breadth for tonnage, 19 feet 6 inches: breadth moulded, 19 feet 5 1/2 inches: depth of hold, 10 feet: diameter of cylinders, 32 inches: length of stroke, 3 feet: diameter of wheel, 16 feet; the floats, or buckets, being 3 feet long by 2 feet broad. Before she was lengthened to her present length
(26 feet more than she formerly was) she had a wheel only 12 feet in diameter, with buckets 8 feet 9 inches long by 22 1/2 inches broad. Mr. Baird's sweeping paddle wheels have been fitted to her not as some people suppose to increase her speed, but to lessen the space occupied by her, in breadth, so that
she may pass through the Welland Canal. - Whilst talking of her wheels, we may mention that her floats are not placed at the exact angle recommended by Mr. Baird, namely, 45 degrees, but at an angle of 32 degrees, the angle at which they were placed in a model sent home to the Admiralty, and which model
was made by the first Engineer of the CHEREOKEE, Mr. Rob't Fothergill. In Mr. Fothergill's model there is, also, two ribs instead of the one which was proposed by Mr. Baird. The Kingston Foundry - Whilst talking of these Government Steamers we may mention that the lengthening of the MOHAWK, the making of her new wheels and powder magazine, and her other outfittings; and also all the brass work, the new capstan, and outfittings of the CHEREOKEE, were done at the above Foundry: and, we know from conversing with all the officers of the Navy, that the work done has given complete satisfaction.
