It will be convenient here to explain what became of these several Furnival properties, and then describe very briefly the stages which led to the inventor’s incarceration in Horsemonger Lane Gaol and caused him to address his Statement of Facts to the Government. In April, 1825, he sold his works at Anderton to the British Rock and Salt Company, which continued to ship salt until 1829. The Marston property appears to have been worked until 1847. The Wharton works were managed by Trustees until 1839, when they were taken over by the National Patent Salt Company, which became one of the most important firms in the Winsford trade. In 1875, Justice Manisty, the surviving leaseholder, transferred his interests to Stubbs Brothers, who, in 1888, disposed of the business to the Salt Union. Furnival had no sooner established himself as a salt-maker at Anderton than the old salt proprietors, “who had contrived in the past to ruin all, or any one who should dare to enter the lists against them,” became seriously alarmed at the apparent magnitude of his plans and the great improvements which threatened both their exorbitant profits and their hitherto unchallenged monopoly. Furnival, to employ a colloquialism, proceeded to “back himself both ways.” Having more than once proved his strength by breaking up “the Coalition” (which the old proprietors had formed to regulate the output and price of salt), and bringing down the price of common salt from 20s. to 8s. per ton, he offered to erect his patent apparatus at his own cost and risk on the works of his wealthy rivals, and to allow them two-thirds of the saving effected by its application. According to Furnival’s unsupported but uncontradicted account, they ridiculed his offer, declaring that they wanted none of his patents, that they could command their own profits in defiance of him, and that they would never sanction any improvements or innovations in the trade. Furnival, who had secured patents for France and the Netherlands, thereafter gave his English competitors a rest and proceeded to erect salt-works at Rotterdam and Ghent capable of taking nearly 60,000 tons of rock salt annually from the British market. But the English salt refiners prompted their Dutch and Belgian _confrères_ to bring official discredit upon the enterprise, and Furnival and his partner were compelled to abandon their works, which had cost them £13,000 to erect, and to forgo the £33,000 they were to have received for their patent rights.
