SO much description cf the v/ays i" whi^'n t^e^e '-neasur ■^r = -ts 

 were obtained a? is needed to render tlsm intelligble. This 

 description is mainly taken from McLean's paper, which deals 

 with the growth .1' soy-bean -lants, but for onl^- -^^-'O of the 

 stations, Easton and Oakland. The present paper gives the 

 m.ain results for soy-bean slants, for all of the stations, 

 together with some attempts at interpretation. This stij-^^- 

 has been carried out partly through financial aid furnished by 

 the Maryland State V/eather Service. 



'^he stations employed were Oakldnd, Ohewsville, Monrovia, 

 College Park, Baltimore, Darlington, Coleman, Saston, and 

 Princess Anne. One station, Oakland, is in the Allegheny 

 plateau. Four stations are 'n the piedmont plateau, one 

 fChev/sville) in the Hagers-^own valley, two CDarlington and 

 Monrovia) in the hilly country north and west of Baltimore, 

 and one (Baltimore) at the Itywer edge of the plateau near 

 Chesapeake bay. Pour stations. College Park, Coleman, 3aston, 

 and Princess Anne, are in the coastal plain. Coleman, 3aston 

 and Princess Anne are eas . . Chesapeake bay, -'-^t^ ^nii c~o 

 Park is west of it and much farther inland, near tiie line of 

 demarcation between th" coastal plain and the piedmont plateau. 

 All ' C-. *-.-•-; o>"_s except Oaklnn'' ere ^t comparatively" l'"^"

 Oakland has an elevation of 775 meters (2500 feet), '^he 

 geographical distribution (rj^-~ ^ig, 1) c:'' +-hese stations is 

 such that considerable differences in climatic conditions 

 exist5between them.
