雷尼先生多年來是在東方從事麵粉生意的領導人物。1907年1月，雷尼麵粉廠由梅含理先生主持開幕。麵粉廠是香港珍貴的資產，因為如果有需要，它們可以隨時供應食物給全港人口，包括軍隊至少四個月。Mr. A. H. Rennie was for many years the leading man in the flour business in the East. In January 1907, the mills were opened by the Hon. Mr. F. H. May. The mills were a valuable addition to the assets of Hong Kong, for they could at any time, if necessary, supply the entire population, including naval and military forces, with food for a period of at least four months.
