25. Pine Seed Collection.-Cones were collected from the Fan Ling plantations, extraction was carried out on concrete floors, which have been specially built for this purpose at Sheung Shui Experimental Garden; up to the end of the year 338 pounds of seeds had been obtained,
26. Insect Pests. For the second year in succession the Pine Tree Caterpillars (Dendrolimus punctatus) appeared in Pine plantation only in exceptionally small numbers. In accordance with advice received from the Bureau of Entomology, Kew, in 1930, all caterpillars collected since that year have been left alive for some time in shallow pits, under conditions that prevented the ultimate emergence of the moths and at the same time allowed of the escape of parasitic enemies of the caterpillars. It is possible that the fortunate absence of the caterpillars during the past two years is due to the strict observance of the advice referred to.
27. Forest and Hill Fires. During the year 79 fires occurred, 40 of them during the month of October; during the previous year only 20 fires were recorded.
28. The usual numerous handbills were distributed and warning notices were posted, prior to the Ching Ming and Chung Yeung Festivals; the vernacular press also kindly gave prominence to notices requesting all visitors to graves and cemeteries to take precautions against causing damage by fire.
29. Public Playgrounds.-Shade trees were planted in the Chinese Recreation Ground, Hollywood Road. Wilful damage and theft necessitated replacements of almost the whole of the stocks of shade trees in the Southorn and Middle Road playgrounds. One corner of the former ground has been enclosed by an unclimbable concrete and barbed wire fence, and this is the only area where the trees are making good progress. Although every tree in the Middle Road ground is strongly protected by an expensive tree guard not one of the original specimens planted in 1935 remains.
30. Paulownia Fortunei, Hemsl. This beautiful tree was introduced by a former Superintendent, Mr. S. T. Dunn in 1905 and flowered for the first time in 1908; although the wood is brittle and the trees receive severe annual punishment from gales, it continues to produce masses of strikingly handsome flowers. A new avenue of 132 trees was planted on the Repulse Bay Road.
31. Cheung Chau.-The roadside planting scheme was increased by the addition of trees of Erythrina indica, Lam., Melaleuca Leucadendron, Linn and Casuarina equisetifolia, Linn. the total number planted was 600. Anti-malarial undergrowth clearing was carried out in vicinity of beaches and dwelling houses.
