ANNUAL REPORT OF THE 



logical Service, Dr. Orville A. Derby, without whose numerous kind 

 attentions it would have been impossible to find, in so short a time, 

 the most profitable localities for the prosecution of his work. 

 Thanks are also due to Dr. Eusebio Paulo Oliveiro, a geologist 

 attached to the service, whose personal information and skillful 

 guidance in the field contributed to the success of the work in hand. 

 To Mr. Frank Egan, General Superintendent of the Sorocabana 

 Railway, the Expedition was under great obligations and was also 

 indebted to Dr. Pacheco of the "Commissao geographica e geolo- 

 gica do Estado de Sao Paulo" who by permission of the Director, 

 Dr. Ioao Pedro Cardoso, aided in making a geological section from 

 Itaicy to Piracicaba. Thanks are especially due to the Chilean 

 Minister of Railways, who granted transportation facilities, and 

 to Colonel Gorgas for courtesies shown in the Canal Zone. Some 

 study of earthquake effects was made in Valparaiso and at King- 

 ston, Jamaica. 



Professor Woodworth in the second half-year gave Course 5 as 

 usual, with the aid of Mr. Lahee and others in the field work; 

 courses 16 and 12, and also supervised the work of five students in 

 Course 20c, viz., Mr. H. C. Durrell, who worked on the geological 

 structure of the Cretaceous section at Mekoniky, Martha's Vine- 

 yard; Mr. W. P. Haynes, who prepared a report on the geology of 

 South Brazil, including observations made while a member of the 

 Shaler Memorial Expedition; Mr. W. G. Reed, Jr., who prepared, 

 partly under the direction of Professor Davis, a paper on the physi- 

 ography of the Sao Paulo region in Brazil; Mr. Edward Wiggles- 

 worth, who prepared a brief paper on the present knowledge of the 

 occurrence of earthquakes in New England in relation to the geo- 

 logical structure, with especial reference to the postglacially faulted 

 slate belts; Mr. G. C. Curtis wrote a detailed description of the 

 coral island of Bora Bora based on personal observations. The 

 greater part of this work consisted in conferences designed to ascer- 

 tain that the students brought to use the materials which they 

 had gathered, and that they expressed themselves clearly with regard 

 to their observations and conclusions. The courses ordinarily 

 offered in geology to Radcliffe students were withdrawn for the 

 year. 



There have been added to the teaching collections some rocks 

 and fossils collected in Montana in 1908 by Dr. Mansfield; and 

 specimens, gifts of Mr. H. C. Durrell, of Cambridge, and of
