There really must have been wheeled traffic hereabouts long before the memory of the oldest folk I ever knew. When they said that they remembered the first cart, I think they must have meant the first cart used for farm-work on the fields. And in the passage I have quoted, Moore only says that a pair of wheels was scarcely to be seen on a farm in the county, not, scarcely to be seen on the roads. But so long as farmers used pack-saddles on their fields, they would use them on the roads as well; and in an agricultural district there would not be much other traffic. The ancient Britons had wagons of some sort in this part of England long before the Romans came here. They used them for bringing down the ingots from the tin mines to the coast, though these ingots went on pack-horses across France to Marseilles. In narrating this, Diodoros says (v. 22) that the ingots were cast in the shape of an astragalos; and an ingot of about that shape was found in Falmouth harbour, and is now in the Museum at Truro. It would hook on to a pack-saddle, and it weighs about 160 lbs., so that a pair would make a load. A century ago a tramway was laid down for bringing granite from the Haytor quarries to the head of the Teigngrace canal, where the granite was transferred to barges and went on to Teignmouth to be shipped. The quarries are about 1200 feet above the head of the canal, and the distance is about six miles in a straight line: so the tramway goes winding round upon an easier gradient, and thus comes within two miles of here. The lines are formed of granite slabs of no fixed size, but usually four or five feet long and one to two feet wide; and they are put down lengthways, with nothing in between them to impede the horses. Each slab has a level surface, about six inches wide, as a track for the wheels, and an upright surface, two or three inches high, to prevent their running off the track; but the remainder of the slab is rough. The gauge is fifty inches between the out-sides of the upright surfaces, and therefore fifty inches between the in-sides of the wheels. This tramway was completed in 1820, and carried down granite for London Bridge, the British Museum, the General Post Office, and other buildings of that time. But it was abandoned when the quarries failed, and now its slabs are used for building or broken up for mending roads.
