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 . rked below the cylinder*and the engine shaft was of cast-iron, square in section,and measured 3| inches on the side. A fly-wheel wasadded to equalize the motion. The vessel was originallyfitted with two pair of paddle-wheels, 7 feet in diameter,having spur-wheels of 3| feet diameter attached, sothat, by means of another spur-wheel of the samediameter, placed between these, and gearing into them,each pair of paddles was rotated at the same arrangement was obviously very inefficient, as theone pair of paddle-wheels worked in the wash of the otherpair, besides the loss of power due to working throughthe toothed wheels. It is said that Robertson, theengineer, tried to dissuade Bell from arranging his wheelsin this manner, but the latter stuck firm to his idea, andthe boat was tried with them, but proved a failure. Thedouble wheels were then removed, and Robertson madeanother engine of about 4-horse power, having a cylinder of12| inches diameter. The workshop where the engine of.
