necessary to construct a freight index covering the whole period;
and, by making allowance for the variations in the price level,
to estimate the freight bill for each year of the period. The pro-
portion of exports for which freight was paid by Australians
has been estimated at 25 per cent. of recorded value.
(0) Insurance. Although there are differences in the rates
quoted by brokers for the different kinds of commodities con-
signed to Australian ports, the great bulk of cargoes falls within

a fairly narrow range of quotation. The two methods of esti-
mating the average rate of freight upon the sample cargo men-
tioned in the last section, and of collecting the impressions of a
number of brokers constantly handling Australian cargoes at
Lloyd’s were employed. The estimate of average insurance upon
which the figures in the accompanying table are based was fixed
in this way at three-eighths of 1 per cent. The method followed
at Lloyd’s in computing the value of cargoes for insurance is to

payable in advance, and to quote the rate upon that total.

tourists moving to and from Australia is necessarily very in-
exact. The records of shipping companies engaged in carrying
