the long Low Moor Waggonway between there and Barnby basin, which was carrying coal by 1802. By 1804, around 10,000 tons was leaving the colliery, although the Dearne and Dove Canal had opened in late 1803, and only about half of the trade travelled the full length of the canal to the Aire and Calder. Coal from the Silkstone collieries was sporadic, as the tramway which had been authorised by the Act of Parliament was not built due to financial constraints. The Barnby Furnace mine failed in May 1807, and the company found itself with no money and little traffic. It obtained a new Act of Parliament on 28 March 1808, authorising it to raise another £43,000 in share capital, and £10,000 by mortgage. They were also able to raise the tolls. The Silkstone Waggonway was completed in 1810. Barnby basin was enlarged to cope with the expected trade, which grew steadily. Coal accounted for just 23 per cent of the 22,270 tons carried in 1800, but had risen to 109,945 tons out of a total of 181,063 tons by 1821. The other main cargoes were corn and limestone. Receipts also rose, from £2,028 in 1803 to 7,649 in 1821, the latter figure being supplemented by a further £2,094 raised from tramway tolls. Profits were sufficient to pay dividends from 1810. In order to keep the boats moving, the Barnsley Canal Company attempted to take water from the River Dearne on several occasions, and were ordered to remove the works which diverted the water by the River Don Navigation Company, who had sponsored the Dearne and Dove Canal. A compromise was reached in 1812, which allowed some of the Dearne water to be used by the Barnsley canal. Between 1828 and 1830, a number of bridges were raised, to allow larger vessels, called "Billy-boys", to use the canal. Competition Competition in the form of railways started to affect the canal from the 1840s. The canal company initially welcomed some of the schemes, but the Don Navigation Company proposed to lease the canal for a year in 1845 and then to buy it, in order to prevent the railways gaining access to the Silkstone coal resources, and to protect the water supplies. They quickly offered to pass the canal on to the Aire and Calder Company, and to buy the Dearne and Dove Canal, but although they took over the Dearne
