s of occupation in the new
regions, especially in Turkestan, also meant a permanent drain on the
national funds. There was a special need for horses, for the people of
the steppes could only be fought by means of cavalry. As the Hsiung-nu
were supplying no horses, and the campaigns were not producing horses
enough as booty, the peasants had to rear horses for the government.
Additional horses were bought at very high prices, and apart from this
the general financing of the wars necessitated increased taxation of the
peasants, a burden on agriculture no less serious than was the enrolment
of many peasants for military service. Finally, the new external trade
did not by any means bring the advantages that had been hoped for. The
tribute missions brought tribute but, to begin with, this meant an
obligation to give presents in return; moreover, these missions had to
be fed and housed in the capital, often for months, as the official
receptions took place only on New Year's Day. Their maintenance entailed
much expense, and meanwhile the members of the missions traded privately
with the inhabitants and the merchants of the capital, buying things
they needed and selling things they had brought in addition to the
tribute. The tribute itself consisted mainly of "precious articles",
which meant strange or rare things of no practical value. The emperor
made use of them as elements of personal luxury, or made presents of
some of them to deserving officials. The gifts offered by the Chinese in
return consisted mainly of silk. Silk was received by the government as
a part of the tax payments and formed an important element of the
revenue of the state. It now went abroad without bringing in any
corresponding return. The private trade carried on by the members of the
missions was equally unserviceable to the Chinese. It, too, took from
them goods of economic value, silk and gold, which went abroad in
exchange for luxury articles of little or no economic importance, such
as glass, precious stones, or stud horses, which in no way benefited the
general population. Thus in this last century B.C. China's economic
situation grew steadily and fairly rapidly worse. The peasants, more
heavily taxed than ever, were impoverished, and yet the exchequer became
not fuller but emptier, so that gold began even to be no longer
available for payments. Wu Ti was aware of the situation and called
different groups together to discuss the problems of economic
