this paper, and that the Indians and Chinese preferred it
(and perhaps they still do) to rag paper or other kinds,
because of the horrible taste it gives the tobacco.

"In China they commonly made paper of bamboo, but more
principally from cotton and a plant which travellers have cited
only by its common name, which they transcribe in various ways,
calling it _kochu_, _kotsu_, or _kotzu_. Today it is known
that this plant is an ulmacea (_Broussonetia papyrifera_)
from a mash of which they still make cloth in Japan. Cotton
paper is superior to it, and naturally more expensive; but
the paper of inferior quality which was received in Manila,
where nothing was imported regularly but common articles of low
price, was of _kotsu._ As all Chinese-made paper it was coated
with alum, the finer [the paper] the thicker [the coating],
for the purpose of whitening it and making the surface smooth,
a deplorable business, for it made the paper very moisture
absorbent, a condition fatal in such a humid climate as
in these islands. Moreover, as the alum used is impure and
contains a large proportion of iron salts, the humidity and
weather oxidize it which finally darkens the paper, so that
Philippine books present a coloration which runs the gamut
of tones from the color of bone to that of dark cinnamon." [3]

Teachings of Christianity," contains the basic elements of the religion
which the missionaries were trying to spread among the unbaptized
in the remote regions of the world, it was the most useful handbook
they had. A summary of the contents of the present edition shows the
