C. F. VON HERRMANN 



Introductory. 

 The object for which the Maryland State Weather Service was or- 

 ganized is to stud}- thoroughly the climatic features of the different 

 sections of Maryland, to ascertain as far as possible the effect of each 

 of the controlling factors, and to publish the ineteurological 

 data available in sufficient detail to enable students to investigate the 

 numerous problems of climate as related to hygiene, agriculture, and 

 the mechanical arts, the solution of which is important for the welfare 

 of the people. Pursuant to this plan, a General Sketch of the Climate 

 of Maryland, by Mr. F. J. Walz, was published in Volume I of the 

 Maryland Weather Service Reports, and a full account of the Weather 

 and Climate of Baltimore, by Dr. Olivci- L. Fassig appeared in Volume 11. 

 Chapters have also been published on the climate of three counties in 

 the State, namely Allegan}', Cecil, and Garrett, and it is intended ulti- 

 mately to cover every county in the State. Collected into one volume, 

 these county reports will form an invaluable repertory of meteorological 

 information ifor the student. The excellent plan adopted in the first 

 sketches published has been but slightly modified in the following account 

 of the climate of Calvert County.
