The numbering and cataloguing of trees in the gardens was completed 
and the card index of woody plants kept up-to-date. The herbarium of 
plants in the gardens was also re-arranged. 
We express thanks to Dr. E. D. B. Wolfe of Sungei Patani for much 
assistance in the collecting of interesting plants, both for the garden and 
the herbarium. The most notable of these was the Petrseovitex mentioned 
under Field Excursions above. 
Buildings .—A new orchid house was constructed in the potting yard, 
size 26 by 15 feet, with open roof of laths, concrete floor and benches. The 
Public Works Department carried out the following works: —a new foot¬ 
bridge from lawn E to lawn H, an extension of the retaining wall below 
lower bridge, repairs to roof of plant-house No. 1, and a new water supply 
for the Gardens from the stream above the upper bridge. This last item 
has provided a supply of water in all parts of the Gardens even in the driest 
weather. The former supply from the smaller side-valleys often failed 
during drought when it was most needed, thus entailing much work in 
carrying water.

lawn C : —Arenga ambong, Actinorhytis calapparia, Borassus machadonis,

GOVERNMENT HOUSE DOMAIN AND OTHER 
OUTSIDE CHARGES 
Singapore 
Government House Domain .—In addition to the usual routine 
maintenance work carried out in recent years, a special vote enabled certain 
improvements of the outlying parts of the Domain to be carried out. In 
the first place, all boundary hedges were re-dug and most were re-planted, 
and considerable additions made to the flowering trees in various parts of 
the Domain. A beginning was then made on a programme of levelling the
