Director. After bringing out twenty-one successive editions 
he transferred the duty to Prof. Oliver, the keeper of the 
Library and Herbarium, who in 1863 included the Arboretum 
in the Guide book. 
In 1850 the Board of ‘Woods and Forests’ was divided into 
two, that of ‘ Works and Public Buildings,’ of which latter 
the Chief Commissioner became a Minister of the Crown ; and 
that of ‘Woods, Forests, and Land Revenues,’ which became 
practically a department of the Treasury. The Botanic 
Gardens and Pleasure Grounds were transferred to the first 
of these as revenue-expending establishments ; the Deer Park 
to the second as revenue-yielding. The Palace and its 
domains, together with the Swiss Cottage in the Pleasure 
Ground and the ground around it, remained under the control 
of the Queen’s Household 1 . 
On this fission of the office its chief, Lord Seymour (after- 
wards twelfth Duke of Somerset), became Chief Commissioner 
of Works and Public Buildings, of which Mr. Philipps retained 
the secretaryship. Mr. Milne, on the other hand, remained 
a Commissioner of Woods and Forests, &c., to my father’s 
great regret, for this gentleman had from the first taken 
a special interest in the development of Kew Gardens, and 
had in many ways smoothed the Director’s path. Happily 
in Lord Seymour and Mr. Philipps my father had excellent 
friends, and I have heard him say that Lord Seymour was 
on the whole, as a man of business and intelligence, the 
most efficient chief he had served under. I must add that 
as First Lord of the Admiralty the Duke continued to show 
his zeal for the establishment he had ruled over. 
The following passages from my father’s correspon- 
dence are interesting as referring to effects retained by 
Mr. Aiton (who died in 1849), on resigning the Directorship 
of Kew : — 
‘Kew, August 13, 1851. I have just received a catalogue 
of the two brothers Aiton’s combined sale, which is to take 
1 Her late Majesty latterly transferred these also to the Department of Works 
and Public Buildings, when they came under the control of the Director of Kew.
