This is the second severe earth tremor registered at the Peabody Museum in the past ten days...
...Rennie, was looking beautiful and young Toes, sociable no end, repeated the remark at home. Kim, the lean Irish rake, who had often enough growled that Rennie had "neither chic nor chien" and who despised the chows as stupid foreigners, bristled at the news, but not in anger. A tremor passed down the lupine spine off big Boris, too, and that very afternoon he was so sentimental about Rennie's glossy brown coat and hang-down ears that Tessa, his Russian-temperamental fiancee, bit him on all four legs. Golden Toes had no idea what it was all about...
...intensity of earthquakes is measured by what is called the Rossi Foucel scale," said Professor Mather. "This scale is based upon the amount of damage done by an earthquake, 10 representing complete destruction and 1 representing an imperceptible tremor. The degrees between these extremes are measured according to whether chimneys are toppled, the amount of vibration felt by people, and so forth. The earthquake in Concord was probably about intensity 4, enough to frighten people...
When asked whether the seismograph at the University Museum had recorded these recent quakes. Professor Mather said that it had responded to the one at Concord, but that there had been no record of the tremor in Japan. This was probably due to the disturbances which have been caused by the construction on the new Chemical Laboratory next door, where the steam shovels cause small earthquakes...
...seismograph, Professor Mather continued, is really two instruments, each pointing in different directions at right angles to each other. This aids in determining the direction from which the tremor comes. Each seismograph has a point which rests upon a revolving cylinder. An earthquake is recorded by the agitation of the line drawn by the point on the cylinder. When there is no agitation in the ground this line is perfectly straight...
