he was engaged in mapping the Pleistocene formations of the 

 Rouse's Point quadrangle in New York, and a part of that area 

 lying in Vermont. A much greater share of his time than usual 

 was given to routine work in the Museum, especially to the in- 

 stallation and working of the seismograph elsewhere referred to. 

 On June 20th he sailed from New York for Rio de Janeiro in 

 charge of the Shaler Memorial Expedition to South America. 



Mr. Eggleston spent three weeks of September, 1907, in the 

 examination of the syenite of Cuttingsville, Yt., and again visited 

 the area in June, 1908. Early in the summer he joined Mr. 

 Varney in a geological and geographical study of the coast of New 

 Brunswick. 



Mr. F. H. Lahee continued his studies of the southern part of 

 the Narragansett basin in the summer of 1908. 



Professor Johnson reports that the course in Economic Geog- 

 raphy (Geology C), offered this year for the first time, was elected 

 by 37 men. In the absence of Professor Davis he conducted the 

 advanced course in Physiography (Geology 20a), in which three 

 men pursued investigations in shoreline topography, drainage 

 modifications, the place occupied by geography in the elemen- 

 tary schools, and the physiographic features of selected states in 

 the Union. One report growing out of this work will be published 

 in the near future. 



During the winter Professor Johnson gave a course of fifteen 

 lectures on Physical Geography in connection with the Teachers' 

 School of Science, under the direction of the Lowell Institute. 

 The lectures were attended by about 115 teachers from Boston 

 and neighboring cities and towns. At a meeting of the geologists 

 of the eastern United States held in New York City in April, Mr. 

 W. G. Reed, Jr., a student in advanced physiography, presented 

 a paper on the development of Nantasket Beach, and Professor 

 Johnson a paper on the origin of beach cusps. 



In June, Professor Johnson sailed for France, where he directed 

 the researches of four students in the volcanic region of the Au- 

 vergne. The following topics were treated: — the physiographic 

 features of the great fault-line scarp west of the Limagne basin, 

 by Mr. S. W. Cushing; drainage modifications due to lava dams, 

 by Mr. W. G. Reed, Jr.; physiographic features due to glacial 

 erosion, by Mr. J. E. Buchanan; and variations in the forms of
