VUl PREFACE. 



tions of broad-leaved trees which have succeeded in other conditions — 

 the poplar, the willow, and the aspen, the elm, the elder, the ash, 

 the acacia, the oak, the hazel, and the dogwood, the birch, and the 

 wild pear. There has been prepared a twin volume, in which these 

 subjects have been discussed. 



This volume was originally compiled in view of what seemed to be 

 required at the Cape of Good Hope. It has been revised, and printed 

 now, only as a contribution towards a renewed enterprise, to arrest and 

 utilise sand-wastes which stretch from Table ' Mountain to the 

 Hottentot Holland Mountains ; and additional information is forth- 

 coming if it should be desired. 



Appended to reports of the Colonial Botanist for 1864 is a letter 

 on grasses adapted to arrest drifting sand (pp. 99-102), and appended 

 to report of the Colonial Botanist for 1865 is a letter on the arrest of 

 drifting sand, and planting the same with trees (pp. 83-93). 



Haddington, 10th April, 1878.
