appearance in any particular place often indi- 

 cate very clearly the character of the soil; 

 Such knowledge may be of considerable use 

 to the cultivator, for he may often thus, at a 

 glance, learn facts of great value concerning 

 certain areas. Thus on rich soils the ' trumpet 

 tree ' or bois canon (Cecropia) ; balisier (Heli- 

 conici) ; the wild egg-plant or sushumber . 

 French weed or Herbe grasse, and nut- grass 

 (Cyperus) are commonly met with. All -spice 

 or bois d? I fide ; logwood ; gru-gru palm and the 

 coco plum are especially characteristic of poor 

 lands. Sedges are almost entirely confined to 

 wet places and French cotton (Calotropis) to 

 sandy localities. 



PRACTICAL WORK. 



Examine the plants which occur in the 

 -.mien, and endeavour to determine where 

 they come from, and how it is that some of 

 them recur again and again after all attempts 

 to get rid of them. In many, this will be found 

 to he due to a good method of seed dispersal. 

 Others, which are exceedingly difficult to get 

 rid of, have underground stems, bulbs, and 

 tubers, which remain in the ground.
