2. Report of the Superintendent of the Coast and Geodetic 

 Survey, O. A. Tittmajstn, shoioing the Progress of the Work 

 from July 1, 1906, to June 30, 1907. Pp. 565, with seven 

 appendixes, numerous plates and 9 maps in pocket. 1907. — The 

 work of the Coast Survey for the period covered by this volume 

 has been in many respects novel, since it included the investiga- 

 tion of the effect of the San Francisco earthquake of April, 1906, 

 on the region in the vicinity of the great fault which extends for 

 a distance of 200 miles, from Point Arena to Monterey. The 

 subject is discussed in detail in Appendix III and some of the 

 conclusions noted are as follows ; First, with reference to an 

 earthquake of 1868, about 1000 square miles of the earth's crust 

 in the region immediately north of San Francisco were perma- 

 nently displaced to the northward about 5*2 feet, the whole area 

 probably moving as a bulk without distortion. During the great 

 earthquake of April, 1906, points on opposite sides of the fault 

 moved in opposite directions, those to the eastward southerly, 

 and those to the westward in a northerly direction, the displace-
