There are definite earthquake zones on the surface of the earth following definite rift lines. They occur where mountain-making is in progress. Large segments of the earth in adjusting themselves in equilibrium exert tremendous pressure. By this process mountains are raised in the course of a few million years, a comparatively short time geologically speaking. From time to time under the huge stresses which fold and warp rocks, the strain becomes too great in the earth's crust, something gives way and the whole earth shakes. No exact, scientific explanation of these movements has been reached...
...under way for its reception and entertainment during the 3 minutes, 36 seconds it will be the guest of the Western Hemisphere. This period of totality is about the average for all total eclipses.

The " belt of totality " of the coming eclipse will be about 100 miles wide. It will pass in a wide curve across...
...constant number and appearance for each species of plant or animal which appear in the cells during cell-division) called the X-or accessory chromosome, which is found in half the spermatozoa of male animals. This is present in addition to the regular number of chromosomes, which always occur in pairs (48 in man), thus giving rise to an uneven number. Ova, on the other hand, in variably have two X-chromosomes. Eggs fertilized by spermatozoa con taining the X-element (thus giving the product a double dose of X's) become females, and the others, males. All experimentalists...

Thereafter the situation eased off in those two states, except in Providence. The telephone Company published advertisements asking the public to bear such inconveniences as might occur and declaring that operators' wages had not been reduced from the war-time peak, that they received two weeks' vacation with full pay each year and other perquisites. The strike appeared to have been broken...
