GEOLOGY — HISTORY. 359 



though they may have Httle du-ect bearing on the specific problem of 

 the genesis of the earth. A considerable part of the rest of the year 

 has been spent in putting this matter in order. Incidental to these 

 two chief lines of work, some progress has been made on the lines of 

 geologic inquiry that seem most to invite future attention — the major 

 dynamics of earth-shaping and the climates of the geologic ages. 



Vaughan, T. Wayland, U. S. Geological Survey, Washington, District of 

 Columbia. Study of the stratigraphic geology and of the fossil corals and 

 associated organisms in several of the smaller West Indian Islands. (For 

 previous report see Year Book No. 14.) 



During the year from October 1, 1915, to September 30, 1916, 

 most of the time which could be spared from my fixed duties on the 

 U. S. Geological Survey was devoted to the completion of three papers 

 in press as parts of Pubhcation No. 213 of the Carnegie Institution of 

 Washington. However, the short papers listed on page 38 of this 

 Year Book were published and the following manuscripts were written : 



An outline of the geotectonic provinces and of the geologic history of the perimeters 



of the Gulf of Mexico and of the Caribbean Sea. 

 An outline of the physiographic features and of the stratigraphic geology of Cuba. 



A summary of the geologic history of the coral faunas of the south- 

 eastern United States, the West Indies, and Central America during 

 Tertiary and Quaternary time is included in a paper entitled "A reef- 

 coral fauna from Carrizo Creek, Imperial County, Cahfornia, and its 

 significance," in press as Professional Paper 98-T of the U. S. Geo- 

 logical Survey. Collections made during February and March 1914, in 

 Antigua, St. Bartholomew, and Anguilla were utilized in the preparation 

 of this paper. The reports on the stratigraphic geology, the paleon- 

 tology, and the geologic history of Cuba and of the Lesser Antilles, 

 are ahnost ready for press. There is no need to repeat information 

 contained in the progress reports pubhshed in Year Book No. 13, pages 

 358-360, and Year Book No. 14, pages 368-373. 



HISTORY. 



Andrews, Charles M., Yale University, New Haven, Connecticut. Prepara- 

 tion of a general history of the colonies in America. (For previous report 

 see Year Book No. 14.) 



Since September 1, 1915, I have continued my investigations as fol- 

 lows: During September I worked in the New York Public Library 

 and the New York Historical Society ; during the academic tenn from 

 October 1 to February 1, 1916, I spent nearly all the week-ends in the 

 Connecticut Archives; beginning February 1 and continuing until 

 September 1, I visited Washington, Richmond, Raleigh, Wihnington, 

 Charleston, and Boston, searching for colonial manuscripts. The bulk 

 of the material gathered will not be used for some time, but one or two 

 brief papers are in preparation as by-products of the investigation.
