 ///. Forests and Moisture ; or Effects of Forests on Humidity

In this are given details of phenomena of vegetation on which

 climate depend of the effects of forests on the humidity of the

 on the moisture of a wide expanse of country, on the local rain- 

 fall and on rivers and of the correspondence between the

 the distribution of forests affected bv the distribution of tho 

 rainfall and the local effects of ft rests on the subsequent

 IV. Hydrology of South Africa; or Details of the Former

 of Causes of its Present Aridity, with Suggestions of 

 Appropriate Remedies for this Ariditity. 

 In this the desiccation of South Africa, from pre-Adaraic 

 times to the present day, is traced by indications supplied by

 interior, with results confirmatory of the opinion that the

 improved forest economy : or the erection of dams to prevent 

 the escape of a portion uf the rainfall to the sea tke abandon-
