Manuscript pocket-diary of Charles Ross of Greenlaw, a Scottish surveyor, architect, farmer, nurseryman and gardener near Paisley, with daily weather readings and notes of his activities and health from 1 January 1795 to 27 June 1805. The diary contains some illustrations. Charles Ross was at the forefront of the Agricultural Revolution in South-West Scotland in the second half of the 18th century. His journal reveals that in his late 70s and early 80s he remained physically and socially active and fully employed despite chronic health problems. It forms a remarkable testimony to life in and around Paisley at the end of the 18th century and beginning of the 19th century.
