found to be $3,763 ; and $3,367 having been the revenue in 1916, by deducting $882, 
the value of the 1915 rubber sold in 1916, and adding $1,264 the value of the 1916 
rubber sold in 1917, the value of the rubber made in 1916 is found to be $3,749, or 
almost the same as in 1915. The difference in the Gardens’ income is thus attributable 
to the conditions under which the rubber was sold. 
The revenue made in Penang, which is almost all from ornamental plants, was 
increased by 3 per cent, $629 against $611. * 
As the Committee of Management for the Waterfall Gardens only came into 
existence late in the year, the $399.76 made earlier was paid into the Treasury; but 
the $227.33 mac le later was banked and is the Committee’s opening balance for 1917. 
Buildings. 
At the turn of the Riding road in the Economic Gardens, Singapore, close to the 
plots where most of the experiments in food plants are being made, the Gardens’ 
Committee built a fruit-store and a house for the Fruit-store keeper. The site was 
selected not only for the convenience of work, but that some protection against thefts 
might be obtained. Beyond this nothing more than petty repairs were executed, both 
in Singapore and in Penang. 
Collections, Records and Investigations. 
Acquisitions include plants and seeds from Messrs. Lawrie C. Rrown, A. T. 
Bryant, St. V. B. Down, W. Lowther Kemp, J. C. Peter, F. 0 . Rasmussen, 
H, B. F. Barnard, H. S. Whiteside and the Rev. Father Couvreur ; from Drs. N. 
Annandale of Calcutta and N. P. Pierce of Sta. Ana, California, Mr. H. N, 
Ridley, lately the Director, and Mr. L. G. REGNARD, Mauritius ; the Royal Botanic 
Gardens, Kew, Calcutta, and Peradeniya ; the Botanic Gardens, Hopetown, Jamaica, 
Trinidad, Hanoi and Buitenzorg ; the Agri-Horticultural Society, Calcutta; from 
Lord Brougham’s garden on the Riviera by the kindness of Lady Swettenham ; from 
the Departments of Agriculture, Egypt, Gold Coast, Nigeria, and Costa Rica : from the 
Bureaux of Agriculture, Washington and Manila; from the College of Agriculture, 
Los Banos, Philippine Islands; from the Forest Department of the Straits Settlements 
and Federated Malay States, the Deputy Conservator of Forests, Tavoy, and the 
Forestry Department, Formosa. 
Roots of no less than 139 races of Canna were the gift of Father Couvreur, which 
sooner or later will be available in quantity sufficient for bedding. Seeds of Warsc- 
zewiczia coccinea were received for the second time from the Botanic Gardens, Trini- 
dad, but the seedlings damped off as before : however, two well-grown plants were 
received later from the Buitenzorg Gardens, from which it is hoped to establish this 
beautiful plant. From Madagascar were received seeds of a Spathodea , which perhaps 
is S', campanulata only ; but as S’, campnnulata never seeds in the Straits, new stock 
is valuable. One seedling was raised from Ceylon seed of the giant bamboo, Dendro - 
calamus giganteus, got in the hope that finer plants might be obtained than exist here. 
Seedlings of the palms Wallichia disticha and Borassus flabelliformis have been raised 
from seed kindly supplied by the Royal Botanic Gardens, Calcutta, and of Phoenix 
Roebelinii from seed sent by M. HAUTEFEUILLE of the Botanic Gardens, Hanoi. 
Cupressus glabra, raised from seed sent to Singapore by the Bureau of Agricul- 
ture, Washington, appears to be a very useful acquisition : a dozen plants of it are at 
present growing well in pots. 
Mr. G. E. S. CUBITT, Conservator of Forests, and his officers, in prosecution of 
the investigation on Dipterocarps and other forest trees, named in last year’s report, 
supplied 98 samples of seed, which were all sown, and the seedlings studied. Two 
papers of results have already appeared in the Journal of the Straits Branch of the 
Royal Asiatic Society. 
Just outside the limits of the Gardens occurs the only known tree of Shorea 
gibbosa. The opportunity of its fruiting was taken to raise seedlings which are being 
established in the Gardens. Near the Shorea stands the only tree in Singapore 
of Ormosia macrodisca, which unfortunately is going to pieces without leaving any 
seedlings of its kind. 
Seedlings of Bombax insigne have been raised from Tavoy seed, and of Bombax 
malabariczwi from Calcutta seed. It has been of interest to notice their stems swollen 
as in the Baobab. 
The Director of the Royal Botanic Gardens, Kew, was so good as to obtain for 
the Gardens seed of two kinds of Quebracho, both of which are growing satisfactorily, 
It is curious that this tan-bark tree had not been introduced earlier.
