Letter from the Rt Hon Arthur James Balfour to William B Hardy Dictated letter. Tells Hardy that his sympathies 'have always been on the side of Science, and I have always preached the absolute necessity of marrying Science to Industry, if the latter is to be fruitful' -- suggests that the Treasury's method of dealing with institutions like the National Physical Laboratory have contributed to a narrow government outlook -- however, points out that real understanding of the best contemporary science work is confined to a very small number of people, none of whom have devoted themselves to government -- 'they are as inevitably ignorant as the public they represent'. 30 March 1918
