Pagina i - No natural science is more instructive, more attractive, and more practically useful, than Meteorology, treated as you have treated it, where the philosophical explanations of the various phenomena of the atmosphere are founded upon an extensive induction of facts. This science is more particularly interesting to the young, because it explains so many things, that are daily occurring around them, and it thus inspires a taste for philosophical reasoning.

Soon the sun rose; but, instead of one sun, we had three; all seemed of equal brilliancy, but, as they continued to rise, the middle one only retained its circular form, while the others shot into huge columns of fire, which blended with the air near their summits. The "breadth of the columns was that of the sun's apparent diameter, and their height about twelve times the same diameter; they were between twenty...

The eye, however, can seldom command a distinct view of these verdant hills ; for overhanging clouds, surcharged with rain, almost constantly veil the spreading tops of the trees. It is a proverbial saying in Chiloe, that it rains six days of the week, and is cloudy on the seventh.
