approaching a post-house, the messenger sounds
a horn, that a fresh horse or horses, according to his company, may be
brought out, and ready to mount immediately. These speedy messengers have
then bellies, loins, and heads firmly swathed, and they always travel as
fast as their horses can go; and such as are able to endure this excessive
riding, are held in great estimation, as nothing is more admired among the
Tartars than good horsemanship.

Between the _lambs_, or large post-houses, there are other habitations, at
three or four miles distance from each other, where foot-posts are
established, every one of whom has his girdle hung round with shrill
sounding bells. These are always in readiness; and when dispatched with the
khans letters, they convey them with great speed to the next foot-post
station, where they hear the sound of the bells from a distance, and some
one is always in readiness to take the letters, and to run on to the next
station: Thus, by constant change of swift runners, the letters are
conveyed with great dispatch to their destinations. By this means, the khan
often receives letters or new fruits in two days, from the distance often
ordinary days journey: As for instance, fruits growing at Cambalu in the
morning, are conveyed to Xandu by the night of the next day. All the people
employed in the posts, besides being exempted from all tribute, have an
ample recompense for their labour from the gatherer of the khans rents.
There are inspectors employed, who examine the state and conduct of these
posts every month, and are empowered to punish those who are guilty of
faults.

The khan sends every year to the different provinces of his empire, to
inquire whether any injuries have been sustained to the crops by tempests,
locusts, worms, or any other calamity; and when any province or district
has suffered damage, the tribute is remitted for that year, and he even
sends corn for food and seed from the public granaries: For in years of
great abundance, he purchases large quantities of grain, which is carefully
preserved for three or four years, by officers appointed for the purpose;
by which means, when a scarcity occurs in any province, the defect may be
supplied from the granaries of the khan in another province. On these
occasions, he orders his grain to be sold at a fourth part of the market
price, and great care is taken to keep his granaries always well supplied.
