VAN WYKS VLEY. 



Period, January, 1884, June, 1885 — 



Evaporation and soakage together ... ... 94 inches 



Ditto, ditto, 1887— 



Evaporation, soakage, and irrigation, 600 morgen 92|- 





The above data (Australian) are to nearest whole numbers. 



The Cape data for 1884-5 are, as stated in the paper read this 

 evening, extravagant. The data for correction of the observations 

 for 1887 are not at hand ; the nearest approximation I can make to 

 net loss by infiltration and evaporation combined is 76 inches.
