ANALYSES OF NOVA SCOTIAN SOILS. HARLOW. 333 



Hence, a soil, whether artifically made by powdering a rock, 

 or taken from a lately deposited marsh area, from a leached 

 hillside or from a field worn out by cropping, will give the 

 essential elements as shown by the analysis of the following: 



A. New tide deposit B. A "worn out" hillside 

 from Gaspereau field from Upper Stew- 



River iacke, Col. Co. 



Insoluble in acid of 1.11 sp. gr. 83.66 80.02 



Potash 72 .42 



Soda (Na 2 0) '. 82 .09 



Lime 9 .55 



Magnesia 1.39 .63 



Sulphuric acid 19 .11 



Ferric oxide * ( 7.7 3.25 



Alumina ( 5.68 



Phosphoric acid 1 .12 



Volatile at red heat 3.57 8.51 



Water at 100 1.1 1.28 



Nitrogen ; 06 1.8 



Further analysis of the same ebb tide water shows in 

 lOOOcc 29.95gm. of dissolved solid made up as follows: 



Sodium chloride 24.24 



Potassium chloride .38 



Magnesium chloride 2.47 



Magnesium bromide .036 



Magnesium sulphate 1.63 



Calcium sulphate 1.18 



In addition to these, Ditmar gives about 30 other ele- 

 ments which are easily proven in salt water. That rock 

 residue may become available to plants has been proven by 

 Wohler, who, in a classical experiment, found the zeolite 

 apophyllite to be sufficiently physically soluble in pure water 

 to be recrystallized from it. F. W. Clarke found muscovite, 

 orthoclase, albite, and othei micas, feldspars and zeolites 

 to be soluble in pure water.
