doing geology for the last six months. He says he has seen in Guadalajara as much as 1000 foot a depth of granite - with large granite boul- ders. Age probably Jurassic. The granite mass constitutes an ancient granitic land to the east= any Llanoria. David Le had also seen Triassic but I much doubt this. It seemed to me that he had but little of his geology in final dated order. at the depot For an hour showed Horton my paleog- ographic maps and explained to him Llanoria and the Mexican Paleozoic geosynclines. Got into the sleeper at 10 P.M. Hand an uphearth. The train moved out at 3 A.M.
