other in order of their age, the oldest lying topograjohically highest. 

 The same year, J. A. Bonsteel published a report on the soils of St. Mary's 

 County. 



The next yenv Shattuck published a report on Cecil County in which 

 he referred to the lignite deposits of St. Mary's County and suggested an 

 explanation of their origin. In 1904 the Miocene deposits of Maryland 

 were fully described by Clark, Shattuck, Dall, Glenn, Martin, and 

 others. In this report a geologic map, sections and many ^photographs 

 were published. In 1906 the St. Mary's Folio, by Shattuck and 

 Miller, was published by the U. S. Geological Survey. This contained a 

 summary of the geology of the county and a geologic map of its south- 

 ern portion. Clark and Mathews also published a summary of the physi- 

 cal features and geologj' of Maryland in which St. Mary's County was 

 given considerable attention. Before the close of the year the report on 

 the Pliocene and Pleistocene deposits of Maryland appeared under the 

 authorship of Clark, Shattuck, HoUick, Lucas, and others. In this 

 report the surficial deposits of St. Mary's County are discussed at great 

 length.
