The fishermen, and other families of Arabs, are 193,000:
making, in all, -811,700 families.
Total strength. Allowing one-fourth for the usual exaggerations of the east,
there would still be about 600,000 families, which, at an average
of four and a half persons to each, would give 2,700,0001'lyats.
The revenue understood to have been collected in 1830 and
1831 on the Kanats and families, gave six millions for the
cultivators, manufacturers, and other fixed inhabitants of the
towns and villages of Persia. The grand total is, therefore,
about eight millions. This is widely different from the forty
millions of subjects, which was the number estimated by
Chardin. It must not, however, be forgotten that Abbas II.
possessed nearly the whole of 'Iran; and if that territory
were included, there would be, according to the preceding
calculations, a population of upwards of thirty millions.
It may not be unacceptable in this place to introduce a table
which will put it in the power of the reader to compare the
preceding account with the state of I'ran about nine centuries
since, at which time much attention appears to have been paid
to the population and revenue of the country.
Ancient As early as the close of the second century of the Hijrah
statistics. guide-books were written, which, according to Ibn Haukal,
contained a description of the curiosities to be found in the
different towns; and likewise a detailed account of the land
and other taxes, the factories, productions, and traffic by ships
as well as caravans. Abu Yusuf has made a statement of
the revenue in the time of Harun al-.Rashid : Ibn Khallikan
has given in much detail that of a portion of the empire;
and Ibn Khaldun has collected with great care accounts of
the productions of 36 provinces; 1 but the following extracts
made by Dr. Aloys Sprenger, M.D., from the valuable manu
script copy written by Ibn Khordadbeh, 630 a. h ., con
tain ample and most interesting details on this subject. 2 The

Library at Oxford, Uri's Catalogue, No. 994; and its antiquity, in addition to
the want of the diacritical points, caused great difficulty in decyphering it.
