summer and excellent quality tomato, cauliflower, cabbage, carrot, celery and watercress in winter. The main types of flowers are chrysanthemum and gladiolus which grow all the year round; dahlia, snapdragon, aster, carnation and rose are grown in winter, and ginger lily and lotus flower in summer. Peach blossom is grown especially for the Lunar New Year. The area of land under vegetables and flowers has increased from 2,250 acres in 1954 to 10,015 acres in 1971.

A wide range of fruit is grown on the lower hill slopes. The princi- pal crops are lychee, longan, wampei, local lemon, orange, tangerine, Japanese apricot, guava, papaya, banana and pineapple. The acreage under orchards in 1954 was 952 acres. By 1971, it was 1,584 acres.

Other field crops such as sweet potatoes, groundnut, millet, soy beans and sugar-cane are cultivated in the drier land where water is inadequate for the planting of rice or vegetables. The acreage under the rainfed crops was 3,450 acres in 1954 compared with 1,978 acres in 1971.

As there is insufficient land for extensive grazing, pigs and poultry are the principal animals reared for food. The pigs of Hong Kong are mostly crosses of local animals with exotic stock, and pure strains of the Chinese type are becoming difficult to find. Although locally produced pigs represent only 16 per cent of total pigs killed, their value is some $51 million per annum, and proposals to stimulate and expand production are being implemented.

The poultry industry, including pigeons and quail, which had an annual production value of $198 million is developing rapidly. Farmers are adopting advanced methods of management and success- fully adapting them to local conditions, taking the process through from locally bred chicks to table birds, using both local breeds and imported hybrids. Duck rearing is also important and steps are being taken to expand this industry. Legislation controlling the slaughter and inspection of Chinese style pressed ducks for export to the United States was passed during 1970.

While local cattle and buffaloes are kept mainly for work, imported Friesians are kept by dairies, the main one on Hong Kong Island and others in smaller groups outside Kowloon and in the New Territories. Regular tuberculin testing is carried out on all dairy animals.

Sporadic outbreaks of a mild type of foot-and-mouth disease (type O) and swine fever still occur, but these have been kept under control by vaccination. Newcastle disease in poultry has been con- trolled by the use of the Ranikhet and intra-nasal-drop vaccines.
