Aiton was a son of the soil, driven out of his own Lanarkshire Eden by poverty, who, like so many other Scots unwelcome to Wilkes and Johnson, came to seek fortune in London. He got a place at the Physic Garden of Chelsea, and thence, perhaps by patronage of Bute, was put in charge of the Princess Dowager’s Botanic Garden, whose reputation throve with his own. His functions must have grown beyond the limits of the Botanic Garden, then only a few acres, for this was the Scotsman who set Cobbett to work, among other jobs, at sweeping up leaves by the Pagoda, on the farther side of the Kew grounds. John Rogers, who worked in the gardens at this time, says that on the death of the elder Haverfield, Aiton came into the entire management both at Kew and Richmond. His first appointment was in the last year of George II. A quarter of a century later, we find him clearly head of the whole establishment. Aiton certainly rose to be no mere working gardener, who published a catalogue of the plants at Kew. He held his post till towards the end of the century, and was then succeeded by his son William Townsend Aiton, to rule at Kew for half a century more; while another son, John, had charge of the royal gardens at Windsor and at Kensington. [Illustration: THE AZALEAS] In the Aiton succession, we come across the fact that a talent for the study of plants is apt to be hereditary. There were two Linnés, not equal in fame, four De Jussieus, three De Candolles, three Darwins of different degrees of note in science; and for more than a century Kew Gardens were under the two dynasties of Aitons and Hookers. In the reign of William Aiton the second, among Scotsmen finding employment in Kew Gardens was a William Macnab, who rose to be foreman here, and in 1810 went to the Edinburgh Botanical Garden as curator or principal gardener. One cannot propitiate Dr. Johnson’s Manes by describing the Edinburgh Garden as a branch from Kew. It is, in fact, an older institution, founded in Charles II.’s reign, and now grown into a model, both of _utile_ and _dulce_, worthy the Modern Athens. The point I have to make is that William Macnab was succeeded at Edinburgh by his son James Macnab, godfather of the _Cupressus Macnabiana_, etc., who managed this garden till his death, 1878, and whose only son, William Ramsay Macnab, bade fair, through a too short life, to continue the family distinction in the botanical world.
