in, and 200 kinds of silks and gauzes.... The weavers
are divided into two guilds, the Nankin and Suchau, and have together
about 7000 looms. Thousands of men and women are engaged in reeling the
thread." (_Rev. H.C. Du Bose, Chin. Rec._, xix. pp. 275-276.)--H.C.]

NOTE 2.--I believe we must not bring Marco to book for the literal
accuracy of his statements as to the bridges; but all travellers have
noticed the number and elegance of the bridges of cut stone in this part
of China; see, for instance, _Van Braam_, II. 107, 119-120, 124, 126;
and _Deguignes_ I. 47, who gives a particular account of the arches.
These are said to be often 50 or 60 feet in span.

["Within the city there are, generally speaking, six canals from North to
South, and six canals from East to West, intersecting one another at from
a quarter to half a mile. There are a hundred and fifty or two hundred
bridges at intervals of two or three hundred yards; some of these with
arches, others with stone slabs thrown across, many of which are twenty
feet in length. The canals are from ten to fifteen feet wide and faced with
stone." (_Rev. H.C. Du Bose, Chin. Rec._, xix., 1888, p. 207).--H.C.]

NOTE 3.--This statement about the abundance of rhubarb in the hills near
Su-chau is believed by the most competent authorities to be quite
erroneous. Rhubarb _is_ exported from Shang-hai, but it is brought
thither from Hankau on the Upper Kiang, and Hankau receives it from the
further west. Indeed Mr. Hanbury, in a note on the subject, adds his
disbelief also that _ginger_ is produced in Kiang-nan. And I see in
the Shang-hai trade-returns of 1865, that there is _no_ ginger among
the exports. [Green ginger is mentioned in the Shang-hai Trade Reports for
1900 among the exports (p. 309) to the amount of 18,756 piculs; none is
mentioned at Su-chau.--H.C.]. Some one, I forget where, has suggested a
confusion with Suh-chau in Kan-suh, the great rhubarb mart, which seems
possible.

["Polo is correct in giving Tangut as the native country of Rhubarb
(_Rheum palmatum_) but no species of Rheum has hitherto been gathered by
our botanists as far south as Kiang-Su, indeed,
