Consequently, the whole course of the Rocky Mountains, and of the Andes as well, marks out the longest "line of weakness" weak-ness" in the world, extending almost al-most from the north pole to the south' pole. From Mount St. Blias, the giant mountain of Alaska 18,- ' 000 feet, to the volcanic region of Terra del Fuego, there is a "line of fissures" nearly 10,000 miles in length.

This is also the most important fact to be remembered by all who live near these treacherous destroyers of life and properly. Almost all volcanoes are like manholes man-holes along a sewer. They are located in rows above long cracks or fissures in the earth's surface, so that when volcanoes, several of which have had eruptions since the glacial epoch. The Sierra Nevada and San Francisco Fran-cisco ranges are also located along a "line of weakness" and have a number num-ber of burned-out craters which were in their day as dangerous as Mont Pe-lee Pe-lee and La Soufriorc. The famous Yellowstone Park rep- . resents a tract of weakness rather than a fissure. The whole region is volcanic and in a constant state of eruption. A short "line of weakness" extends through. Colorado and New Mexico, containinfg several extinct volcanoes. And f r.i (Itietomala to Costa Rica is a volcanic bIi v.'iih cones from 8,000 to 10,000 feet high.

"A line of fissures runs from tho Aleutian f Hands southward through North ana South America to Terra del Fuego. t-nd all along the course of this gigantic crevice there may be an earthquake at nny time." According to the experts of the United States Gealogir-al Survey there is a fissure or "line of weakness" which begins at Tr.jy, X'.
