THE WEB OF LIFE 61 



occvirs in the quite unrelated true ants. Finally, 

 the web is illustrated by the numerous boarders, 

 mostly beetles, that are found in the termitaries — 

 not hostile intruders or parasites, but guests which 

 are fed and cared for apparently for tho sake of 

 a palatable exudation with a pleasant, narcotising 

 effect on the termites. With a centre in termites, 

 what a variety of interests must we not include 

 within the radius of their Hfe and work! — fungi 

 and trees, beetles and birds, lizards and ant-eaters, 

 and man more than any. 



The Hand op Life upon the Earth. — The 

 hand of life has been working upon the earth for 

 untold ages. Take plants, for instance. The sea- 

 weeds lessen the force of the waves, the lichens 

 eat into the rocks, the mosses form huge sponges 

 on the moors which keep the streams flowing 

 in days of drought. Many httle plants are for

 grass — which began to appear in Tertiary ages — • 

 protects the earth hke a garment ; the forests 

 afEect rainfall and temper climate, besides sheltering 

 multitudes of living things, to many of whom every 

 blow of the axe is a death-knell. No plant, from 

 bacterium to oak-tree, hves or dies to itself, or

 animals there are destructive borers and burrowers 

 and conservative agents, such as the coral-polyps 

 and the chalk-forming Foraminifera.
