s fruit and _flowers
like cloves_" (p. 28). The cassia-buds have indeed a general resemblance to
cloves, but they are shorter, lighter in colour, and not angular. The
cinnamon, mentioned in the next lines as abundantly produced in the same
region, was no doubt one of the inferior sorts, called cassia-bark.

Williams says: "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.

[Captain Gill (_River of Golden Sand_, II. p. 263) writes: "There were
chestnut trees..; and the Kwei-Hua, a tree 'with leaves like the laurel,
and with a small white flower, like the clove,' having a delicious, though
rather a luscious smell. This was the Cassia, and I can find no words more
suitable to describe it than those of Polo which I have just used."--H. C]

_Ethnology_.--The Chinese at Ch'eng-tu fu, according to Richthofen,
classify the aborigines of the Sze-ch'wan frontier as _Man-tzu, Lolo,
Si-fan_, and _Tibetan_. Of these the Si-fan are furthest north, and extend
far into Tibet. The Man-tzu (properly so called) are regarded as the
remnant of the ancient occupants of Sze-ch'wan, and now
