“Even in the years 1861 and 1862, when I visited these towns, they told me, though with much reserve, that the people of Cojutepeque and Chinameca kept this barbarous custom to prevent the failure of the fish.” Near the end of November, 1879, a series of earthquakes shook the lake (more than six hundred were counted), and on Jan. 11, 1880, the waters had risen about four feet. On the next day, between half-past four and half-past seven in the afternoon, 13,790,000 cubic metres of water escaped from the outlet of the lake, making a stream of greater volume than the Seine at Paris or the Rhine at Basle. The little river Jiboa, which received this torrent, did great damage to the plantations on its banks. As is usual, the earthquakes were accompanied by the discharge of sulphuretted hydrogen, now in such quantities as to be very unpleasant at the city of San Salvador. On the 9th of January there appeared floating on the surface numerous flakes of a black foam composed of ferric sulphide, which in contact with flame burned with a slight explosion. On the 20th, at eleven o’clock in the evening, a great disturbance was noticed in the midst of the lake, and the next morning a pile of rocks was seen, from whose midst arose a column of vapor. For more than a month this vapor column was visible, and the pile of rocks near the centre of the lake increased, while the water was heated and the sulphurous vapors extended over all the neighborhood. Beyond this no permanent volcano was formed above the level of the lake (1,600 feet above the sea). It is dangerous to form conclusions as to the general course of volcanic action anywhere, for science is very much in the dark as to the causes of eruptions and earthquakes, as to the condition of the interior of our globe, whether fluid or solid, and also as to whether the lavas poured out during an eruption have been fluid since the earth was formed, or have been suddenly melted either as cause or effect of what we call an eruption. In the Central American volcanic region, as was stated at the beginning of this chapter, little has been done in the way of scientific exploration, and the facts recorded, beyond popular accounts of some especial disturbance, are so meagre that no large space would be required to present them to the reader. This is not, however, the place to enter into a scientific discussion, and I must content myself with a few bare statements.
