pies about 70 acres, and the remainder is given to arboretum and 
pleasure grounds. There are two main greenhouses: 1. The 
palm house, 362 feet long, the central dome rising 66 feet ; 2. The 
temperate house, of which the central portion is 212 feet long, 
137 feet broad and about 60 feet high, flanked by wings which 
give a total length of about 580 feet, the whole covering between 
one and one and one-half acres of ground. There are also four- 
teen other houses, grouped in two ranges and more or less con- 
nected, given to special collections. There are three botanical 
museums: I. Devoted to economic products; 2. to miscellaneous 
Products; 3. to timbers. There is also a large museum hall given 
to the exhibition of floral paintings by the late Marienne North. 
There is a small laboratory equipped for research in physiological 
botany. The herbarium and library occupy the old palace of the 
King of Hanover, near the main entrance to the garden, and they 
are the largest and most complete in the world. The herbaceous 
ground is planted in long parallel “beds and contains several thou- 
sand species. The arboretum is thoroughly illustrative of all 
trees that will grow in the open at Kew, and the shrubs are, for 
the most part, cultivated in areas by themselves. There are 
numerous special features, such as the rock garden, the bamboo 
garden and the American garden. 
The research work of Kew is principally economic and taxo- 
nomic. Around it centre the 24 botanical gardens and botanical 
Stations of the British Colonies, which are manned chiefly by men 
who have studied or worked at Kew. The principal publications 
at present emanating from Kew are: 
1. The Kew Bulletin of Miscellaneous Information. 
- Hooker’s Icones Plantarum. 
- The Continuation of Hooker’s Flora of India. 
- The Continuation of the Flora of Tropical Africa. 
- Annual Reports. 
- The Index Kewensis. 
The monographs and separate writings of its staff of scientific 
men are too numerous to review at this point. 
3. The Royal Botanical Garden of Berlin is situated in the 
southwestern part of the city, but a project for moving it out into 
the country is now being seriously considered. The palm house
