Copy letter from Robert William Frederick Harrison, to Messrs Wildsen & Company Harrison sends a cheque for their account for Welsh coal. He asks, given their steady use of Welsh steam coal for heating apparatus throughout the winter, whether Wildsen would consider giving a contract price at the beginning of the winter for a certain number of tons. They lack the storage for a winter supply of this type in addition to the house coal. He enquires if there is a cheaper type of coal which would be suitable for their furnace. He also asks if they are able to obtain a winter's supply of "coalite" for them in lieu of ordinary coal, and whether it would occupy more space than an equivalent volume of ordinary coal. 29 April 1907
