The early 1790s were a time when there was an increasing demand for coal, but a shortage in many places because much of the coal being produced was being consumed by industries close to the mines. There were coal reserves near Barnsley, but no transport links to distribute it to the region. In July 1792, the Aire and Calder Canal Company asked William Martin, who was the manager of the canal, to prepare plans for a link from near Wakefield to the Barnsley mines. Hearing of the plans, the River Don Navigation Company proposed an alternative, which involved the canalisation of the River Dearne, to reach the same destination. The Aire and Calder scheme foresaw a healthy trade in coal and manufactured goods from Barnsley to the Aire and Calder, and agricultural lime from Knottingley in the reverse direction. Martin and the Aire and Calder's resident engineers surveyed the route, and at a public meeting held on 20 September 1792, the canal engineer William Jessop suggested that the line from just below Wakefield to Barnsley and Silkstone could be built for approximately £50,000. The Aire and Calder decided to subscribe £20,000 for shares, to ensure that they held a majority shareholding. A further meeting in mid-October reported that the cost was now £60,000, and that 86 people had subscribed to it. The River Don company attended the meeting, as they were keen to use the Barnsley to Silkstone route for their Dearne and Dove Canal, but an agreement was reached, whereby the Barnsley Canal company would build the Barnby to Barnsley section, but no water would be taken from the River Dearne, which was needed to supply the Dearne and Dove canal. A branch from Barugh to Haigh Bridge, including an extra seven locks, was added to the scheme. The Aire and Calder proposed to pump all the water for the canal from the River Calder, using steam-driven pumps at Agbrigg, Walton and Barugh. The Haigh branch would have required a fourth engine, but the Haigh furnace closed and the branch was never built. The pumps at Walton and Agbrigg were replaced by a reservoir at Cold Hiendley, which increased the construction costs by £3,000, but reduced running costs by £350 per year. An Act of Parliament was obtained on 3 June 1793, which created the company and authorised them to raise £72,000 by the issuing of shares, with an
