“ As a large landowner Kinnaird made himself practically acquainted with agriculture, and was one of the earliest reformers of the old style of husbandry prevailing in the Carse of Gowrie. Steam-ploughs and threshing-machines were first used in Scotland on his estate, and having an aptitude for mechanics, he himself devised various improvements in agricultural implements. He energetically sought to ameliorate the condition of the labouring classes, organising evening schools for the ploughmen, and establishing free reading-rooms and libraries about his estate. ”
