Production. ~~ 88. The value of rubber products in 1923 was thus 36 per cent.
greater than in 1921; in 1925 it had increased by another 31 per
cent. over 1923, chiefly as the result of the increase of £44,700,000
in the cost of materials. In the rubber tyre branch of the industry
the value of the products in 1925 was £190,000,000, an increase of
about 44 per cent. over the value in 1923. The decline in the
number of establishments in the tyre branch, from 160 in 1993
to 109 in 1927, indicates the tendency towards centralisation of the
iyre industry. There was also a decline in the number of estab-
lishments in the rubber boot and shoe branch, while for other
rubber products the number showed an increase.
89. The total value of the output of the rubber industry in 1927
was slightly less than that for 1925, although greater than that
for 1923. Reductions in tyre prices were responsible for this
decline. The value of the output of boots and shoes, in 1927 , Was
higher than that for 1925 although less than that for 1923. For
other kinds of rubber manufactures the value in 1927 wag higher
than in previous census vear.
