the Zambezi bridge towards Tete, with a view to exploiting the
Moatise coalfield. By this time, however, labour was wanted
above all for growing cotton. The promotion of cotton-growing
had for some years been one aim of Portuguese colonial policy.
The expansion of Portugal's textile industry in the early years of
the century had been supplied mainly from outside its empire. In
an attempt to reduce this drain of foreign exchange, the military
government introduced in 1926 a decree designed to boost
cotton-production in the colonies. Zones were specified within
which Africans could discharge labour obligations by growing
cotton, while the right to buy, process and market cotton would
be leased to companies. This scheme only began to make progress
after
1933,
when a minimum price for cotton was introduced, and
the main impetus came in 1938 when a Cotton Export Board was
set up to provide seed, train experts and conduct research.
Between 1935 and 1940 cotton output in Mozambique, mostly
from the northern districts, rose from 2,300 tons to 19,000 tons,
for which Portugal paid 30 per cent below the world price. The
advent of war intensified the drive to produce cotton, which on
the lower Zambezi caused the extortion of forced labour from
women at the expense of their own food supplies. Intolerable
conditions continued to drive many people from northern Moza-
mbique to settle in Nyasaland, especially Mlanje district; even
though the British discouraged this in the 1930s, it is likely that
in the course of the decade there were at least 50,000 such
migrants.

By 1940 the pressure to produce for export had placed great
strain on traditional farming methods and the ecological balance
of even the most fertile regions. The concession companies could
all command contract labour in generous quantities. As a result
they tended to increase output by essentially labour-intensive
methods. There was little technical advance and Mozambique
became a producer of primary products, many of which, like
cashew nuts, had to be sent abroad even for preliminary proces-
sing. Factories existed to make fireworks, perfume, bus bodies,
ice,
tin cans, lime, soap and furniture, and to process maize, tea,

and 1945, allowing for an element of natural increase: cf. R. R. Kuczynski,
