 fp. 566^ _^i/.y. '5^, Jigs. Gl). — This is the first of a proposed series of 

 reports dealing with the climatic features of Maryland, including the 

 physiography, meteorology, h3"drograph3', medical climatology, agri- 

 cultural soils, foresty, crop conditions, and flora and fauna of the 

 State. The present volume is confined to a discussion of physiograplw 

 and meteorology, and includes the following articles: Introduction, by 

 W. B. Clark, explaining the establishment of the State weather service 

 and the lines of investigations pursued; A general report on the phys- 

 iography of Maryland, and The aims and methods of meteorological 

 work, by C. Abbe; A sketch of the progress of meteorolog}^ in Mary- 

 land and Delaware, by O. L. Fassig; and An outline of the present 

 knowledge of the meteorolog}" and climatology of Maryland, bv 

 F. J. Walz.
