Madras) and four seedlings from the Peradeniya plant of 
B. formosa in Section E. 
Section R. Eleven plants Eucalyptus Naudiniana. 
Section S'. Elceocarpus ganitrus, Nyctanthes arbor-tristis, Lawsonia 
alba, Guettarda speciosa, Malvaviscus Conzatii, Michcelia 
champaca, Thunbergia Kirkii. 
Masonry .—In addition to the work described above, concrete kerbs 
were made along several more of the roads. These define the road edges 
and make the work of keeping them trim much less. The concrete path to 
the office was re-made. 
Seedlings of Bougainvilleas and other shrubs .—In addition to the seeds 
obtained in 1935, one seedlings has been raised from the Madras plant of 
B. formosa, and two seedlings from a plant of B. glabra on Penang Hill. 
Many seedlings of the F* generation of B. lateritia have been obtained. 
Some of the seedlings of the Peradeniya plant of B. formosa have 
flowered and have proved to be inferior to the parent plant. The seedlings 
of Mrs. Frazer, Rosa Catalina, and the hill B. glabra have not yet flowered. 
Seedlings of Holmskioldia sanguined, Petrea volubilis, and Petrea 
rugosa have been raised for the first time. These species do not usually 
produce seeds in Malaya. Among the seedlings of Holmskioldia is some 
colour variation, three plants showing only a trace of the red colour. 
Further breeding might produce a good yellow or orange variety. 
Anti-malarial work .—Operations of the Health Department were carried 
out on various ravines round the Gardens to prevent dangerous mosquito 
breeding. This work occupied the greater part of the year. 
GOVERNMENT HOUSE DOMAIN AND OTHER OUTSIDE 
CHARGES 
Singapore 
Government House Domain .—As in former years, the maintenance of 
grounds was carried out by the Gardens Department, Mr. J. C. Nauen 
being in charge of the work throughout the year. Improvements were 
effected in the nursery and potting yard, and in the areas near the House; 
in the outlying areas, only grass cutting and some attention to recently 
planted trees was possible. 
Along the main drive (Edinburgh Road) twenty badly grown Poinciana 
trees were cut down and replaced by young plants. The work was 
thoroughly done, each planting hole being made 8 to 10 feet in diameter 
and 5 feet fleep; a foot or more of drainage material was put into the bottom 
of each hole and 35 lorry loads of new earth used. The grass verges were 
renewed in sections. 
O11 the second terrace in front of the House three Livistona palms were 
removed to allow for the lengthening and symmetrical arrangement of 
flower borders. These borders were planted with Russellia sarmentosa, 
Plumbago capensis, Pentas carnea and var. alba, and Pentas coccinea, all 
being edged with cream Zephyranthes. Beds of fatropha hastata 'and 
Crotons were added to the row beside the path circling the tennis courts. 
The grass verges in front of the House and bordering the main drives on 
either side of the terraces were replanted and those by the drives also 
widened and made uniform. Hippeastrum and Zephyranthes bulbs were 
planted under the groups of Ptychosperma palms. All Cannas were 
replanted in November. The herbaceous borders were completely replanted
