| Hardening Contd. (2) nickel steel gears, was overdue, but could not be expected for another week. Refrigerator. With reference to the refrigerator plant, Mr Nadin informed the Committee that he had discussed the matter with Mr Haslam, who would submit a scheme shortly. Mr Haslam had informed Mr Nadin that the Daimler Co. were obtaining from Messrs Haslam a cooling plant for the same purpose, but apparently they had not specified a plant which would give a degree of cooling we believed advisable. They had evidently appreciated the importance of keeping the temperature of the oil used for hardening purposes within reasonable limits, but had not advanced quite so far as we had in this respect.
