canal to its present terminus, where a connection was made to the Cromford sough, even though they had to purchase the land from Arkwright at £1000 and landscape (at unknown cost) the grounds of his then house. Water could be drawn from the sough at night as well as on Sundays, when Cromford Mill was not working. Coming from underground, it was slightly warm, and it was said that it never froze. (Arkwright had been using the sough water to power Cromford Mill since the previous century.) The opening of the Nottingham Canal provided further water via the Butterley Reservoir, almost above Butterley Tunnel and on the summit level of the Cromford Canal. The sign illustrated (left) was displayed at both ends of the Butterley tunnel, and stressed the importance of only using the narrow tunnel in any one direction at particular times. There are reported instances of fines levied for non-compliance with these rules. In 1819 the Mansfield and Pinxton Railway opened up trade with Mansfield including moulding sand for the foundries. In 1831, the Cromford and High Peak Railway opened a route up to Manchester The canal also carried limestone from the Butterley Company's quarry at Crich with a plateway to the Amber Wharf at Bullbridge. In an attempt to avoid using cable-haulage or a rack and pinion system, a remarkable steam engine, the "Steam Horse" was tried out in 1813. In 1840 when the North Midland Railway was built, George Stephenson was faced with the problem at Bullbridge of taking the line over the road but under the canal, thus the Bullbridge Aqueduct, in its final form, placed the river, road, railway and canal at four levels. In 1846 the mining beneath Wirksworth had reached such a depth that Meerbrook Sough was built, draining into the Derwent near Whatstandwell, which deprived both Arkwrights mill and the canal of water, leaving the latter with only that from Butterley Reservoir. Accordingly, the canal owners first hired a pump and then built the Leawood Pump House in 1849 buying a Cornish type beam engine from Grahams of Elscar. Decline In 1802 the canal had carried over 150,000 tons and by 1842 nearly 300,000, then in 1849, the Manchester, Buxton, Matlock and Midlands Junction Railway was built alongside as far as Ambergate, which reached Manchester in 1867. A further line to Pye Bridge was built in 1875. By 1888 trade had
