Letter from C F Cross of Cross & Beaven Analytical and Consulting Chemists to William B Hardy Does not think there are any figures to be circulated [to the sub-committee on alcohol], but has information on the production of alcohol from carbide in Switzerland -- notes that the 'immediate practical solution to the problem is the wood process' and that it would be important to have the figures as to the production of waste wood, sawdust, and chips. 14 February 1917
