The Municipalities of Singapore and of Georgetown, Penang, contribute 
towards the upkeep of the Department $300 and $1,200 respectively in 
return for advice upon roadside trees, etc.; and the Municipality of Singapore, 
further, meets the expenditure incurred by reason of music in the Gardens. 
Expenditure in Singapore was greatly reduced: the cost of labour was 
$18,315 against $33,294 in 1921: and of stores, tools, travelling, books and 
book-binding $14,013 against $17,235. 
Half of this reduction had been anticipated in preparing the estimates : 
the other half was by savings effected during the year. 
The expenditure on labour in Penang was $900 less than in 1921 and 
upon stores, tools and miscellaneous $560 less. 
Investigations and Collections. 
For many years the local rainfall has been read in the Botanic Gardens, 
Singapore. From September, 1922, the observations were extended to 
temperature, evaporation and humidity, the instruments having been sup¬ 
plied by Dr. Gilbert Brooke, and the readings 'are daily transmitted to him 
for official record.

bin Hassan, Ahmed bin Hadji Omar and Abdul Kadir of Singapore and 
a number of Malay and Chinese exhibitors who at the close of the Malay- 
Borneo Exhibition allowed the Department to select from their exhibits; the 
^ Royal Botanic Gardens, Kew, Calcutta and Peradeniya; the Botanic Gar¬ 
dens, Buitenzorg. Cambridge, Port Darwin, and Saigon; the Jardin Colonial 
of Laecken, and Mr. A. Robertson-Proschowsky of the Jardin d’ Acclima- 
tation ££ Les tropiques” at Nice, the Chief Forest Officer, Zomba, British 
Central Africa; and the Director of the Amani Experimental Station, 
Tanganyika territory ; the Conservator of Forests, S. S. and F. M. S., and 
his officers; M. M. Andrieux-Vilmorin et Cie., the Arnold Arboretum, 
Jamaica Plain, Mass., U. S. A., the Department of Agriculture of the United 
States, and the Experimental Stations in Hawaii and Porto Rico. 
Owing to identity of climate between the south of the Malay Peninsula 
and the lower Amazon valley, an exchange has long been sought with the 
Botanic Gardens, Para, but cannot be obtained. In default of this the kind¬ 
ness of Mr. Davidson in sending seeds is greatly appreciated. 
♦ 
Mr. Frost gave to the Waterfall Gardens a large consignment of 
Dendrobia from the South Sea islands in return for assistance rendered 
earlier in connection with collecting. 
Mr. G. H. Vernon’s gift of a large plant of Dendrobium Johannis was. 
much appreciated. It was exhibited at a meeting of the Singapore Natural 
History Society and a note upon it will be found in the Society’s trans¬ 
actions. The seed of Widdringtonia Whitei which the Chief Forest Officer, 
Zomba, so kindly procured, has given a supply of seedlings: they are being 
carefully nursed. The Director of the Amani Experimental Station 
supplied seed of Vitex Volkensii which yields a new drug; seedlings have 
been raised. 
Casuarina Rumphii was successfully raised from seed from Buitenzorg. 
Kew and Cambridge supplied collections of Kalanchoe.
