2. The development of Malaya’s resources has 
been carried out in the main by imported labour. The 
amount of skilled labour employed is comparatively 
small and is drawn mostly from China. The chief 
demand is for unskilled labour — a demand which the 
indigenous Malay population has been quite insufficient 
to meet. The supply has been supplemented from 
three sources: — 
1. India. 
2. China. 
3. Certain of the islands of the Malay Archi- 
pelago of which the principal are Java and 
Sumatra. 
The third source of supply has not provided anything 
comparable to the number of labourers that have come 
fo this country from India and China, but it cannot 
be entirely ignored in any review of Malayan labour 
and is probably capable if necessary of further 
development. 
3- The three main classes of employment requir- 
ing unskilled labour are: — 
1. Agricultural estates, of which rubber estates 
are by far the most important, 
2. Tin mining. 
3. Essential public services such as roads and 
railways. 
Of these the tin mines are worked almost entirely 
by Chinese, the estates mostly by Indian labour though 
considerable numbers of Chinese, Javanese and Malays 
are also employed.
