Note 8 — VII

Erd and Picketing, of the United States exploring expedition, determined the height to be 6,500 English feet (7,143 Spanish), not an unsatisfactory result, considering the imperfect means they possessed for making a proper measurement. In the Manila Estado geografico for 1865, the height is given, without any statement as to the source whence the estimate is derived, as 7,030 feet. The same authority says, “the large volcano is extinct since 1730, in which year its last eruption took place. The mountain burst into flames on the southern side, threw up streams of water, burning lava, and stones of an enormous size; traces of the last can be observed as far as the village of Sariaya. The crater is perhaps a league in circumference, it is highest on the northern side, and its interior is shaped like an egg-shell: the depth of the crater apparently extends half-way down the height of the mountain.”
