Brushmakers
W J Wilson, brush and mop manufacturer, placed a large advertisement in the Western Times in 1835, in which he thanked the inhabitants of Ashburton for their support over the previous 6 years. He listed 38 types of brushes that were always available, including horse brushes, shoe brushes, hair brushes, painter's tools of all description, flue brushes, cementing brushes, hatter's brushes and wool mops.

A General Election was taking place during January and February* of 1835.  At about the same date Mr Wilson also wrote to the Western Times, claiming that he had been offered £30 by a member of Mr Palmer's committee not to vote for Mr Lushington. John Jennings, the chairman of the committee, wrote a strong denial in reply.

The editor noted that this was one person's word against another's, and that it was 'very possible' that the committee would not have offered a bribe. He added, however, that 'it is by no means certain that some of his friends did not resort to the disgraceful practice.'

* There was not one single day for voting at this time.
