th those found here. These
are hemispherical in form, and consist for the most part of coir
(coco fibers); and, as if prepared by the hand of man, the whole
interior is covered with an irregular net-work of fine threads of
the glutinous edible substance, as well as the upper edge, which
swells gently outwards from the center towards the sides, and expands
into two wing-shaped prolongations, resting on one another, by which
the nest is fixed to the wall. Dr. v. Martens conjectures that the
designation salangane comes from langayah, bird, and the Malay prefix
sa, and signifies especially the nest as something coming from the
bird.--("Journal of Ornith.," Jan., 1866.)

[135] According to the Catalogue, the following ores are
found:--Variegated copper ore (cobre gris abigarrado), arsenious copper
(c. gris arsenical), vitreous copper (c. vitreo), copper pyrites
(pirita de cobre), solid copper (mata cobriza), and black copper
(c. negro). The ores of most frequent occurrence have the following
composition--A, according to an analyzed specimen in the School of
Mines at Madrid; B, according to the analysis of Santos, the mean of
several specimens taken from different places:--

Silicious Acid 25.800 47.06
Sulphur 31.715 44.44
Copper 24.640 16.64

[136] According to the prices current with us, the value would be
calculated at about $12; the value of the analyzed specimen, to which
we have before referred, $14.50.

[137] In Daet at that season six nuts cost one cuarto; and in Nags,
only fifteen leagues away by water, they expected to sell two nuts for
nine cuartos (twenty-sevenfold). The fact was that in Naga, at that
time, one nut fetched two cuartos--twelve times as much as in Daet.

[138] N. Loney asserts, in one of his excellent reports, that there
never is a deficiency of suitable laborers. As an example, at the
unloading of a ship in Iloilo, many were brought together at one
time, induced by the small rise of wages from one to one and one-half
reales; even
