144 PROCEEDINGS OF THE CALIFORNIA 



Dr. Blake closed the discussion by remarking that what was 

 wanted about earthquakes was facts, not theories. Unfortunately, 

 the circumstances attending these phenomena are not favorable to a 

 careful collection of data, and our knowledge is not sufficient to 

 afford a complete explanation. 



Dr. Gibbons gave the result of some recent observations on cloud 

 currents in the upper and lower atmosphere, preceding the late rain. 

 The two currents moved in opposite directions, but apparently in 

 obedience to some common impulse, and finally coalesced. The 

 barometer rose, instead of falling, as the rain approached, and until 

 it fairly set in, and was rapidly falling as the sun broke out and 

 the rain ceased. 



Prof. Davidson gave the result of his observations on the glacial 

 grooves in the southeastern part of Vancouver and adjacent islands. 

 They bear north 9*^ east, true. The rock in which they are found 

 is a highly crystalline feldspar and hornblende. 



He gave the result of his measurement by triangulation of the 

 height of Mt. Baker as follows: north peak, 10,719 feet; south 

 peak, 10,079 ; upper part of the crater, 10,123 ; bottom part of 

 crater, 9,925 ; slope of crater, 30 degrees ; length of crater, 407 

 feet. 



These measurements were never before given. The height of the 

 snow line on the west side of the mountain was found to be 5,301 

 feet, which is 2,150 feet greater than the elevation reported by 

 Alexander Agassiz, which has generally been distrusted. 



Mr. Hanks referred to the reported finding of a ship on the 

 Colorado desert, alleged to have been stranded there centuries ago 

 by the recession of the sea, and proposed that a committee be 

 appointed to investigate the facts. 



Mr. Hanks said that Col. Evans had described the ship in an 

 article published in the Galaxy. 



A motion was carried that Col. Evans be invited to address the 

 Academy on the subject, and that Mr. Hanks be appointed a 

 committee to gather evidence on the subject.
