Noah Howell, collier v Arthur William Latham and John Harper.

Howell trying to recover £60 being the balance due in regard of the purchase of his share in the gale by Latham and Harper.
Howell was granted the gale as a free miner but by arrangement it was registered in the name of Harper in 1891 or 92.  The gale was opened by Howell and his son at a cost of £18.  Latham then became anxious to get a share.  It was agreed that the interests of Howell and Harper should be treated as worth £100 each and that Latham should pay £100 to equalise capital.  Howell to be working manager at 30s. a week plus a third of the profits.  At the end of twelve months Howell was reduced to 24s. a week.  Latham and Harper were then to pay  Howell £100 for his share if he got out in February 1895.  He was actually only paid £40 plus an I.O.U.
Mr. Latham had blossomed into a colliery proprietor, living in a house at Ross with three collieries and two coal stations and 40 or 50 men in his employ.
‘What is Latham?’  ‘He was a Baptist minister, but I suppose he found coal business better than preaching.’
Noah Howell had in 1891 applied for the gale.  Traded as the Darkhill & Ellwood Colliery Co.
In October 1898 there was a dispute between Latham and Harper.  The former paid Harper £300+ for his share in the gale.
Latham carried on business as the Pheonix Coal Co. at Ross.
Colliery had been a great loss.
Found in favour of Howell plus costs.
