 for the low values shown by the periods "beginning Sept. 7 and 

 Oct. 8 may lie in ^he fact that the ninimum temperature dropped 

 in both these ^j«ix'.. ih tu u. point only severax i«grees tbove

 for the most part less than 100, ?;ith rela"^jvely lo-.^^ niidsuriner

 spectively. The Baltimore plant graphs b = gin -vith high values, 

 and reach maxima of 183 and 233 for stem height and leaf- 

 product respec^^ively. For Darlington the main feajtures of the 

 plant graphs that serve to distingaish this station from others 

 are the very high maxima of 226 for the stem hejght and 295 for 



leaf-product, for the period beginning July 10 :nd the x-rxative-
