down not only by pass-laws but by cash debts and much-prized
grazing rights. The latter helped workers to support families:
altogether, there were over two million Africans living on white
farms in 1936. But the combined effect of immiseration in the
reserves and artificial barriers to mobility was to depress real farm
wages even below their value in 1910.
Other fields of employment expanded fast. Between 1929 and
1939 the black workforce in manufacturing nearly doubled, while
that on the mines rose by one-third to 424,000, the first major
increase since 1907—10. During the worst of the depression, from
1929 to 1933, the Transvaal mines reduced their reliance on
contract labour from Mozambique

in favour of men from
within the Union, of whom only 40 per cent were contracted by
labour recruiters. In the same period, the proportion of mine-
workers from the Cape in the Transvaal rose from 30 to 43 per
cent, even though by 1935 one-third of job-seekers from the
Transkei were rejected by the mines on medical grounds. Mean-
while, the recent discovery of a sulphonamide drug provided a
cure for the pneumonia to which mineworkers from the tropics
were specially prone. In 1934, under pressure from the mine
companies, the government allowed a gradual resumption of
recruitment north of latitude 22°S, and by 1939 the Transvaal
mines employed some 20,000 men from central Africa, mostly
from Nyasaland. On the goldmines, increasing mechanisation
underground widened the scope for white workers: by 1939 there
were 43,000, almost twice as many as in the later 1920s. However,
there was no marked change in real wages for either black or white
mineworkers, which in 1941 were much the same as they had been
in
1911.

This was broadly true of workers in other industries
and in government or municipal employment. Annual wages for
black workers in manufacturing averaged £41 to £46 in 1924-37;
mineworkers earned two-thirds as much.
By and large, the boom in goldmining had the effect of
intensifying existing trends towards white proletarianisation and
black dependence on wage labour. Between 1921 and 1936 the
number of whites in urban areas increased by a
half,
yet that of
blacks in urban areas doubled. Moreover, there were clear signs
that Africans were tending increasingly to make their homes in

A new labour convention had been made with Portugal in 1928; cf. p. 516.
