Halse, who was apparently descended from a ‘historian of Cornwall of the same name’, settled in St. Ives around 1790, established himself as an attorney and became town clerk and an alderman. He was also ‘one of the most enterprising and successful adventurers in mines’ of his day, and he ‘derived a large part of his substantial fortune’ from the Wheal Reeth tin mine, which he had reopened. His other main venture was the St. Ives Consols tin mine, which he opened in 1818 and used to build an electoral interest by creating the village of Halsetown, within the borough boundary, to accommodate his workers.
He was a silent Member whose occasional votes exhibited independent Tory leanings. He divided against Catholic relief, 6 Mar., and for the spring guns bill, 23 Mar. 1827. He was granted six weeks’ leave for urgent business, ‘having served on an election committee’, 30 Mar. He voted against Canning’s ministry for the separation of bankruptcy jurisdiction from chancery, 22 May, but with them for the grant to improve water communications in Canada, 12 June 1827. He divided for repeal of the Test Acts, 26 Feb., but against Catholic relief, 12 May 1828. He voted with the duke of Wellington’s ministry against abolition of the office of lieutenant-general of the ordnance, 4 July, but divided for the corporate funds bill, 10 July 1828. In February 1829 Planta, the patronage secretary, correctly predicted that he would side ‘with government’ for Catholic emancipation. He voted accordingly, 6 Mar., but was in the largely Whig minority for allowing Daniel O’Connell to take his seat without swearing the oath of supremacy, 18 May 1829. He divided against Jewish emancipation, 17 May 1830. He was presumably the ‘James Hulse’ who voted for the grant for South American missions and against abolition of the death penalty for forgery, 7 June 1830. At the general election that summer he was defeated at St. Ives by the new interest established by Wellington’s nephew, William Pole Long Wellesley*.
By the time of the 1831 general election Halse had reasserted his position and he was returned unopposed in conjunction with the reformer Edward Bulwer Lytton.
At the general election of 1832 Halse was returned for St. Ives, now a single Member borough, as a ‘reformer’. He sat until his death in May 1838, by which time he was a ‘Conservative’.
