horticulture and we shall have occasion presently to refer to the most important of all his campaigns in the cause of science.
When John Lindley was about 19 or 20 years of age his father's affairs became involved, and the son with an impulsiveness as just as it was foolish insisted, against the advice of friends, on becoming surety for the father. The mill-stone of financial anxiety thus early hung about his neck caused him trouble throughout his life.
Possessed of nothing but youth, a sound education, great natural ability and one good friend, John Lindley at the age of 20 left Norfolk for London. Thanks to a letter of introduction from the friend (Sir William Hooker) he obtained a post as assistant-librarian to Sir Joseph Banks. He thus gained access to a good library and became acquainted with a large number of men, both English and foreign, interested in scientific subjects. That he made the most of his opportunities is evident, for we find him at 21 a Fellow of the Linnean Society and a member of the Bonn Academy of Natural History. In 1822 began Lindley's long connection with the Horticultural Society, which he served first as Garden Assistant-Secretary, then (1826–1860) as Assistant-Secretary and finally as Secretary.

The most conspicuous direct services rendered by Lindley to the Society were the laying out of the Society's garden at Chiswick and the organisation, with Bentham, of the celebrated flower-shows which have served as models for the exhibits of horticultural societies all over the world. Those who know how extraordinarily valuable, not only to horticulturists but also to botanists, are the periodical "shows" held by the Royal Horticultural Society, will be grateful to Lindley for the perspicuity which led him to replace the old and gaudy "fêtes" by these admirable exhibitions.
Lindley's Professorship of Botany in University College, London, dates from 1828 and was held for over a quarter of a century. Among those who attended his lectures were
