The slow elevations here referred to may be looked upon as being one of the more important factors in the production of earthquakes. By various causes the rocky coast is bent until, having reached the limit of its elasticity, it snaps, and, in flying back like a broken spring, causes the jars and tremors of an earthquake. If this is the case, then the number of earthquakes felt in a district which is being elevated may possibly be a function of the rate of elevation. APPENDIX.
