(the southern half) the masonry is composed of two layers of stone. On the borough half (the northern end) the depth of the stone runs to three layers. When the river level is low, the bases of the previous bridge can be seen in the water immediately upstream of the present bridge. Tolls and earnings The day-to-day running of the turnpike became the responsibility of the Richmond-Lancaster Trust. Between 1758 and 1799, the trust charged a flat rate of 10d for transit throughout the town of Richmond and the borough of Richmondshire. Prices for transit along the route to Lancaster were initially quite high (typically 4 Shillings and 6 pence [4s, 6d]), which was later relaxed when in 1756, an Act of Parliament allowed the turnpike trusts to charge for the carriage of coal. Fothergill noted that the volume of coal traffic using the route from Durham was stopping the route from being rebuilt when it fell into disrepair. Thereafter, charges amounted to 10d for twenty cattle, 5d for twenty sheep, 1d for a laden horse and 6d for three or four horse carriages. In the period from 1825 to 1829, the trust typically paid an interest rate to its shareholders of 5% per year. Besides the droving of animals, which had been going on via the Cam High Road for centuries anyway, goods taken to Richmond were groceries, drink, mahogany and other timber, with corn and butter going westwards from Swaledale and Wensleydale. In 1835, the total receipts from the tollhouses in the eastern district was £271, 7 shillings and sixpence. £116 was spent on wages for labour, tradesmen, the treasurer (£10) and the clerk (£5). However, the trust was in debt to the tune of over £4,100. Conversely, the western district had toll receipts of over £515 and paid their treasurer and clerk twice as much as the eastern district. Their debts were slightly higher at £5,200. In early 1796, the combination of suspected Jacobean uprisings, the Corn Laws and the high price of food, resulted in rioting breaking out through Wensleydale. At least 300 people were rioting within of Bolton Castle, which made the authorities dispatch a "troop of Horse" to deal with the issue. However, the rioters agreed not to interrupt the delivery of grain on the turnpike through the dale. Trust closure A report prepared for Parliament in 1851 stated that the trustees had left
