James Halse was MP for St Ives between 1826 and 1838, a period which saw six general elections and the passing of the Great Reform Act of 1832. He lost the seat briefly at the August 1830 election but regained it the next year in July 1831. He was elected for the 4th time on January 7th 1835.
Halse is probably best remembered for building the mining village of Halsetown for his workforce from St Ives Consols mine. Halsetown was, for Cornwall, an unusual venture which resembled the colliery villages of the north England in so far as it provided tied cottages to employees. It's a village planned in the light of Robert Owen's New Lanark and as such forward looking. Halse made a fortune from mining in a time when competition was pretty cut-throat, bankruptcies common and regulation non-existent. It's not surprising therefore that his establishment of Halsetown has been seen by some as a cynical ploy to establish a secure electoral base in the face of the 1832 electoral reform legislation. The franchise was widened and the male householders of Halsetown now had a vote but it would be perilous to use it against against their landlord and employer. By 1841 there were 86 households in Halsetown providing James Halse with a secure political base while his mining investments in Wheel Reeth and St Ives Consols, together with other mines such as Boscaswell Downs in St Just, provided a secure financial base.
