The Municipalities of Singapore and Georgetown, Penang, contributed 
$300 and $1,200 respectively towards the cost of maintenance, in return for 
advice upon roadside trees, etc.; and the Municipality of Singapore met the 
cost of music in the Gardens. 
Expenditure in Singapore was far below the votes, chiefly by reason of 
a reduction of the labour employed in the Economic Garden to one watchman, 
one mandor, and on an average 77 men per diem. Expenditure in Penang 
used up the whole of the votes for Penang; and they were supplemented by 
two amounts transferred from savings in Singapore. 
BUILDINGS. 
In Singapore quarters for six hindu watchmen, ten married tamil coolies, 
six subordinates, and a barrack for thirty unmarried men were erected, and 
occupied as soon as ready; whereupon the temporary lines for tamils in the 
Economic Garden and the condemned lines for the watchmen were abandoned 
and pulled down. 
A Tea-kiosk was erected in the Gardens and gas was laid on tc the 
Laboratory. 
In Penang Plant-house No. 3 was re-erected, plant-house No. 10 demo¬ 
lished, and a new house srbuilt upon a more suitable spot. 
INVESTIGATIONS AND COLLECTIONS. 
Living collections .—For the gift of plants and seeds the following are 
thanked:—Messrs. Ahmed bin Hassan, and J S. W. Arthur; Captain 
H. Berkeley, o.b.e.; Messrs. D. R. Boyce, L. C. Brown, and 
G. B. Deshmukh; Dr. F. W. Foxworthy; Mrs. Lim of Union Street, 
Penang; Messrs. G. Rican, B. K. Sahib, C. L. Samuel, Akira Satow, Tan 
Chye Sian, Tan Tang Nian, and W. L. Wood; His Siamese Majesty’s 
Consul-General; the Agricultural Experiment Station of Santiago de las 
Vegas, Cuba; the Botanic Gardens of Kew, Port Darwin, Buitenzorg and 
Kingston, Jamaica; the Departments of Agriculture of the United States 
and Union of South Africa, and the Superintendent of Horticultural 
Operations, Delhi, India. 
The total number cf plants inwards to Singapore was 721 with 513 packets 
of seed; and to Penang 936 with 315 packets of seed. The Director, when 
returning, brought with him four Wardian cases and three boxes of plants, 
containing 147 species as a gift from the Royal Botanic Gardens, Kew, and 
a number of supplementary purchases. By the kindness of the Director the 
whole had been assembled and packed at Kew. 
At the end of the year 1922 the Chief Forest Officer, British Central 
Africa, supplied seeds of the Mlanji cedar; the seedlings are growing satis¬ 
factorily in Singapore; but they damped off in Penang. The Montezuma 
pine is one of the new introductions to the Gardens in Singapore. 
Among living plants brought into cultivation in Penang as the result 
of a collecting trip in Kelantan, is a new and showy Dendrobium, — 
D. Haniffii, Ricll. The Dendrobium mentioned in the last report as the gift 
of Mr. J. C. Frost, has flowered well and proved to be D. atro-violaccum. 
Of the new species received in Penang in the form of seed from Delhi 
but few survived the seedling stage. What suits the climate of northern 
India is scarcely likely to suit that of Penang, and indeed in general does not. 
In 1918 it was discovered that the Gardens possessed a tree of Hevea 
confusa; and lest it should hybridise with the Para rubber trees and so cause 
deterioration of the Gardens’ seed, it was removed as soon as determined. 
Two seeds from it were preserved and the resulting seedlings planted in the 
Botanic Gardens near the main gate; they flowered at the end of 1923. and 
both were found to be hybrids. They were destroyed immediately, having- 
served the purpose of showing how readily H. confusa and H. brasiliensis 
cross.
