[The hot springs.] The hot springs of Los Banos are numerous, and in their vicinity large quantities of steam are seen to issue from the shore of the lake.  There are about a dozen which give out a copious supply of water.  The principal one has been enclosed, and made to flow through a stone aqueduct, which discharges a considerable stream.  The temperature of the water as it leaves the aqueduct is 178 deg..  The villagers use it for cooking and washing; the signs of the former employment are evident enough from the quantities of feathers from the poultry that have been scalded and plucked preparatory to cooking.  The baths are formed by a small circular building six feet in diameter, erected over the point of discharge for the purpose of securing a steam-bath; the temperature of these is 160 deg. and 140 deg..  A change of temperature is said to have occurred in the latter.

The rocks in the vicinity are all tufa, and some of the springs break out close to the cold water of the lake.  Near the aqueduct, a stone wall surrounds one of the principal outlets.  Two-thirds of the area thus enclosed is occupied by a pond of warm water, and the other third is divided into two stone reservoirs, built for baths.  These baths had at one time a high reputation, and were a very fashionable resort for the society of Manila; but their celebrity gradually diminished, and the whole premises have gone out of repair, and are fast falling to ruin.

The water of the springs has no perceptible taste, and only a very faint smell of sulphur is perceived.  No gas escapes from it, but a white incrustation covers the stones over which the water flows.

Some of these waters were obtained, and since our return were put into the hands of Dr. C. T. Jackson, of Boston, who gives the following analysis: 

Specific gravity, 1.0043; thermometer 60 deg.; barometer 30.05 in.

A quantity of the water, equal in bulk to three thousand grains of distilled water, on evaporation gave—­

Dry salts, 5.95 grains.

A quantity of the water, equal in bulk to one thousand grains of distilled water, was operated on for each of the following ingredients: 

    Chlorine 0.66
    Carbonic acid 0.16
    Sulphuric acid 0.03
    Soda and sodium 0.97
    Magnesia 0.09

[Mount Maquiling.] On Mount Maquiling, wild buffaloes, hogs, a small species of deer, and monkeys are found.  Birds are also very numerous, and among them is the horn-bill; the noise made by this bird resembles a loud barking; report speaks of them as an excellent bird for the table.  Our gentlemen reached their lodging-place as the night closed in, and the next day again embarked for Manila, regretting that time
