C. Davison on “Earthquakes in Mining Districts” (Geol. Mag., 
no. 491, May, 1905, pp. 219-223) describes three shocks apparently 
due to the removal of coal or the pumping out of water, which 
resulted in underground slips along fault planes. 
The great Cullinan diamond is described and illustrated by Hatch 
and Costorphine in the Geological Magazine (no. 490, decade s, vol. 
II, pp. 170—171, 1905) in an article entitled * Big Diamond from the 
Transvaal." 
A summary of the laws of the various states regarding underground 
waters has been prepared by Dr. D. W. Johnson, and published as 
Water Supply and Irrigation Paper, 122, of the United States Geo- 
logical Survey, under the title “Relation of the Law to Under- 
ground Water." 
The pollution of the water of Lake Champlain by the discharge of 
waste from pulp mills and sewage has been studied by M. O 
Leighton of the United States Geological Survey, and the results of 
this investigation are published as Water Supply and Irrigation 
Paper, 121 —“ A Preliminary Report on the Pollution of Lake 
Champlain." 
A valuable bibliography of 628 titles of the different papers on
