The Clyde from its source to the sea, its development as a navigable river, the rise and progress of marine engineering and shipbuilding on its banks, and the leading historical, geological, and meteorological features of the Clyde Valley . a laterdate, tried the running of a steamer above the name of Robert Napier, however, is linked toothers who took a leading part in the development ofocean-going steamers. We find the history of eventsbringing us in contact with great commercial undertak-ings, and one more especially where the Clyde and theMersey in some measure joined hands. In 1824 the firm at that time being only about 7 lbs. on tlio square inch, with a piston speed of240 feet per minute. With the higher pressures now used and greater pistonspeeds, the indicated horse-power is about five times the nominal. Nominalhorse-power, as a commercial term, may be calculated by squaring the diameterof piston in inches and dividing the result by 12 for a non-condensing engine,and by 24 for a condensing engine. THE RIVER, 209 of Messrs. G. & J. Burns was started, their vessels ply-ing to the North of Ireland. In 1828 they built theirfirst steamer for the Liverpool traffic.

Burns andMr. Napier took aleading part, his en-gines were placed inthe first steamer ofthe company, andthe steamers them-selves were all built on the Clyde by such well-knownfirms as those of Duncan, Wood, and Steele. In connection with this it is interesting to notice thatthe four vessels with which the Cunard Coy. startedin the Liverpool and American service in 1840, Britannia, Acadia, Caledonia, and Columbia, allwooden paddle boats of about 1100 tons burthen each,have been year by year added to until the total number ofboats used since that t
