"Cassia grows in all the southern provinces of China,
especially Kwang-si and Yun-nan, also in Annam, Japan, and the Isles of the
Archipelago. The wood, bark, buds, seeds, twigs, pods, leaves, oil, are all
objects of commerce..... The buds (kwei-tz') are the fleshy ovaries of
the seeds; they are pressed at one end, so that they bear some resemblance
to cloves in shape." Upwards of 500 piculs (about 30 tons), valued at 30
dollars each, are annually exported to Europe and India. (Chin. Commercial
Guide, 113-114).
The only doubt as regards this explanation will probably be whether the
cassia would be found at such a height as we may suppose to be that of the
country in question above the sea-level. I know that cassia bark is
gathered in the Kasia Hills of Eastern Bengal up to a height of about 4000
feet above the sea, and at least the valleys of "Caindu" are probably not
too elevated for this product. Indeed, that of the Kin-sha or Brius, near
where I suppose Polo to cross it, is only 2600 feet. Positive evidence I
cannot adduce. No cassia or cinnamon was met with by M. Garnier's party
where they intersected this region.
But in this 2nd edition I am able to state on the authority of Baron
Richthofen that cassia is produced in the whole length of the valley of
Kien-ch'ang (which is, as we shall see in the notes on next chapter,
Caindu), though in no other part of Sze-ch'wan nor in Northern Yun-nan.
