To get to Liskeard above the navigable river, the means of transport was on the backs of horses: the first wheeled wagon was introduced into the Liskeard district in 1790. As late as the 1830s, pack horses and mules were the general means of transport for goods throughout the county, once off the turnpike roads. Approaching 10 tonnes (11 short tons) of limestone were required per acre annually (about 25 tonnes per hectare), so that its transport was a considerable undertaking.
