of erosion of the surrounding country vjhich largely governs the present physical 

 condition of the lakes. 



An endeavour has been made to express numerically the differences 

 arising from these conditions of erosion, the results being included in 

 Table I. As an expression of the types of slopes and soil-covering of the 

 surrounding country, the percentage of cultivated land aud alluvial pasture is 

 given for the drainage system of each lake. The steeper slopes are either
