Marco's somewhat
rude description of the process, 'Il prennent la sel e la font cuire, et
puis la gitent en forme,' points to the manufacture spoken of in this
note. The cut which we give from M. Garnier's work illustrates the process,
but the cakes are vastly greater than Marco's. Instead of a half pound they
weigh a preul, i.e. 133-1/3 lbs. In Sze-ch'wan the brine wells are bored
to a depth of 700 to 1000 feet, and the brine is drawn up in bamboo tubes
by a gin. In Yun-nan the wells are much less deep, and a succession of hand
pumps is used to raise the brine.

[Mr. Hosie has a chapter (Three Years in W. China, VII.) to which he
has given the title of Through Caindu to Carajan, regarding salt he
writes (p. 121). "The brine wells from which the salt is derived be at Pai
yen ching, 14 miles to the south west of the city [of Yen yuan] ... [they]
are only two in number, and comparatively shallow, being only 50 feet in
depth.
