The laboratory was among the best equipped for its time and was visited by Smithells and Wyndham Dunstan of the Imperial Institute who appreciated the work done. He worked on a diverse range of problems including reclaiming saline soils, problems relating to the sugar industry, the tea industry, food contamination, and on chemical control of insect pests.
