t, productive land is always appropriated,
and in many parts of the Islands is difficult and expensive to
purchase. Near Manila, and in Bulacan, land has for many years past
cost over $225 (silver) an acre.

[57] In Buitenzorger's garden, Java, the author observed, however,
some specimens growing in fresh water.

[58] Boyle, in his Adventures among the Dyaks, mentions that he
actually found pneumatic tinder-boxes, made of bamboo, in use among
the Dyaks; Bastian met with them in Burmah. Boyle saw a Dyak place
some tinder on a broken piece of earthenware, holding it steady with
his thumb while he struck it a sharp blow with a piece of bamboo. The
tinder took fire. Wallace observed the same method of striking a
light in Ternate.

[59] Centigrade is changed to Fahrenheit by multiplying by nine-fifths
and adding thirty-two.--C.

[60] Tylor (Anahuac 227) says that this word is derived from the
Mexican petlatl, a mat. The inhabitants of the Philippines call this
petate, and from the Mexican petla-calli, a mat "house," derive petaca,

[63] According to the report of an engineer, the sand banks are caused
by the river San Mateo, which runs into the Pasig at right angles
shortly after the latter leaves the Lagoon; in the rainy season it
brings down a quantity of mud, which is heaped up and embanked by the
south-west winds that prevail at the time. It would, therefore, be of
little use to remove the sandbanks without giving the San Mateo, the
cause of their existence, a direct and separate outlet into the lake.

[64] They take baths for their maladies, and have hot springs for
this purpose, particularly along the shore of the king's lake (Estang
du Roy, instead of Estang de Bay by a printer's mistake apparently),
which is in the Island of Manila.--Thevenot.

[65] "One can scarcely walk thirty paces between Mount Makiling and
a place called Bacon, which lies to the east of Los Banos, without
meeting several kinds of natural springs, some very hot, some lukewarm,
some of the temperature of the atmosphere, and some very cold. In a
description of this place given in our archives for the year 1739, it
is recorded that a hill called Natognos lies a mile to the south-east
of the village, on the plateau of which there is a small plain 400
feet square, which is kept in constant motion by the v
