BRITISH CENTRAL AFRICA
Meanwhile, the British government had given its backing in 1929
to plans for a railway bridge across the Zambezi, while preventing
the one thing which might have made it pay — the development
of
the
Moatize coalfield, opposite Tete, which would have
challenged Welsh exports
to
South Africa. Once again,
the
financing was underpinned by Nyasaland, which paid interest on
debentures out
of
loans from the Colonial Development Fund.
When the bridge was opened in
1935,
Nyasaland's public debt had
swollen to over £jm: this was relatively the heaviest such burden
in British colonial Africa,
for in
that year revenue was only
£422,000 and exports worth only £736,000. Between 1930 and
1936 the number of Africans employed within the territory fell
from about 80,000 to
5
o,ooo (many of whom were immigrants),
and in the latter year as many as 120,000 people from Nyasaland
were employed outside its borders. The railway was extended in
1935 from Blantyre to Lake Nyasa, but this had much less effect
on the revival of export values in 1934-8 than the expansion of
tea-planting due
to
a favourable international quota secured
in
1933;
in
1938-9 tea briefly replaced tobacco as the chief export
commodity. As elsewhere
at
the time, the government tried
to
shore up its revenues by increasing African cash-crop production,
but in 1936
it
formally acknowledged its dependence on labour
exports,
in
agreements which regularised
the
recruitment
of
workers
for
Southern Rhodesia and South Africa.
No
great
changes in numbers resulted, but the government was now able
to control migration more easily and ensure that Nyasaland
received some return from the contribution made by its workers
elsewhere.
For most Central Africans the decade of the 1930s was bleak.
Yet there were important gradations and exceptions within the
overall pattern of rural deprivation. Villages were indeed often
half-emptied of their men: in northern Nyasaland and eastern and
north-eastern Northern Rhodesia the absentee rate was between
40 and
60
per cent. This strained the capacity
of
those who
remained
to
grow food for themselves, but some communities
were able to cope better than others. In northern Nyasaland, the
lakeside Tonga adjusted to the loss of male labour by netting fish
and cultivating cassava, which women could grow with little or
no male assistance. In the woodlands of Northern Rhodesia, male
labour was essential for bush clearance and tree-lopping. This
could be secured
if,
as among the Mambwe, the men of
a
