December 27, 1903, Thursday. Spent the day at the meeting of the C. S. A. in the Astoria Building. Payton's Presidential Address on Criteria of Congric Conclution appeared to me to set up a lot of "sham creel" to have the fun of knocking them down. He is going it strong on showing that the Legalian of Congric Percentage of the living is erroneous. Dana stated this once than to success, and beside Payton often uses them in his own oral conclution. White's Presidential Address on Isostasy printed much later, the results of which come to show as well as can be that the crust is in isotatic balance. Borries paper on the old and new triangulation of California made a plain case that this state is undojing a tricol of "sham creels." There is with local horizontal movement, a general movement from the south to the north. Cushman and I had a long talk on the value of trams in underground conclution.
