39. Mr. David T. Fullaway, Entomologist and Chief Plant Inspector, Board of Commissioners of Agriculture and Forestry, Honolulu, Hawaii, again very kindly supplied the Department with a consignment of the Plume Moth (Platyptilia pusillidactyla). The insects were sent in a carton by air from Honolulu to Manila, then by ship to Hong Kong. For several days following their arrival, numbers of moths were liberated on Lantana flowers, in various parts of the Colony. Flower buds of the Lantana which are infested by Plume Moths do not open and consequently cannot produce seed. So far there is no evidence of the moth having established itself in the Colony.
40. Protection of Plantations.-The clearing of all fire barriers and forestry paths was carried out before the commencement of the dry season. The total length of old fire barriers dealt with was 49 miles and forestry paths 46 miles. New fire barriers were formed at Shek O, Tai Hang and Tsat Tze Mui; new forestry paths were made on Mount Collinson, Shek O and Taipo Kau Forestry Reserve.
41. Undergrowth Clearing.-In Hong Kong, Kowloon and the New Territories, the total areas cleared in connection with anti-malarial work totalled 2,997,815 square feet; other clearing carried out in connection with surveys, building development and traffic requirements amounted to 791,695 square feet.
AGRICULTURE, ETC.
42. Fan Ling Experimental Garden. The plots of Citrus were given a weekly spraying of lime-sulphur mixture throughout the whole year. Two well-known varieties, Chiu Chau Kom and Tim Chang made good progress and produced heavy crops of fruits; a plot of another very interesting but lesser-known Citrus, named locally as Sha Kom, and obtained from two isolated trees in a village near Taipo, was planted and at the end of the year produced a small number of fruits. This sour Citrus is a beautifully coloured fruit and is from one to two pounds in weight. The cultivation of the Citrus, generally, appears to be almost entirely neglected in the New Territories. It would be greatly to the advantage of the residents if healthy stocks of plants could be introduced and planted in place of the very poor types of orchards which are to be seen in the vicinity of nearly all villages.
43. Inspection of Nursery Stock and Vegetable Products. The following shipments were inspected and certified as fit for export-Sixty-four of fresh and dried vegetables to the Philippine Islands, three of mixed lily bulbs and twenty-three of Narcissus Tazetta, containing 81,660 bulbs to Britain, Honolulu, Germany, United States of America, Australia and Canada, twenty lots of Sugar Cane, totalling 132,000 pieces to Malaya and twenty-six small lots of mixed seeds and plants to various other countries.
