THE impending retirement of Sir Daniel Hall from the directorship of the John Innes Horticultural Institution will presumably close his very long connexion with agricultural administration and research. From the time when he was the first principal of the South-Eastern Agricultural College, Wye, and throughout his directorship of the Rothamsted Experimental Station, his tenure of office as principal scientific adviser to the Ministry of Agriculture and Fisheries, and lately as director of the John Innes Institution, Sir Daniel has impressed all by his knowledge, his sound judgment and tact, and not least by his great ability as a writer and speaker. Like the late Lord Ernie, and his successor at Rothamsted, Sir Daniel excels in the art of exposition, and British scientific agriculture has indeed been fortunate in commanding the services of men of this type. Now that he has passed the stage when, in the pursuit of duty, it is no longer necessary to “rise earlier than virtue and go to bed later than vice”, we hope that Sir Daniel will find occasion to continue his great interest in the social contacts of science ; but no one will grudge him time to devote to oriental art and other “digressions of a man of science”. Science needs men like him who can write and speak, as well as think and do, in order that its voice may be heard amidst the disharmonies of a world torn by political turmoil and social strife.
