just as well? Probably the result would be that it 

 would be dead in a week or more. How, then, are we 

 to account for plants being sidUcl to their surroundings, 

 so that we can talk of water plants, veld plants, Karroo 

 plants, desert plants, Alpine or high mountainous 

 plants, and even Arctic and Antarctic plants ? That is 

 to say, when we study all the plants found in these 

 very different kinds of surroundings, we find they can 

 live and thrive there ; but many of them will not live 

 at all if transferred from one place to another, especially 

 if the heat and cold, wet and dry surroundings, be very 

 different in amount. 



The Distribution and Evolution of plants all over 

 the world is done as follows : — 



First, we have to disperse the fruits and seeds ; as 

 when they were first brought by bii-ds, wind, or water 

 into Cape Colony, for they could not have come north-

 they do it is by maldng hulls. Though the flowers and
