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 analj^sis 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.O) 82 .09 



Lime 9 .55 



Magnesia 1.39 .63 



Sulphuric acid 19 .11 



Ferric oxide j 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 phj^sicallj^ 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.
