PERSONALITY OF PLANTS 
they have free-swimming larvae analogous to 
the active zoospores of certain members of the 
plant world. 
The first land vegetation of the globe must 
have presented a curious spectacle. Imagine 
a forest consisting of endless repetitions of Al- 
gae, Fungi, Lichens, Liverworts and Mosses, 
with many forms of gigantic sizes. The fresh- 
water Algae early developed a clever device 
to save their race from extinction by drought. 
Certain cells in each plant became hard and 
devoid of water, presenting that phenomenon 
of suspended animation to be observed in many 
of the higher seeds. When drought overtook 
any particular plant, it died, but these special 
restive cells lived, and were carried about by 
the wind or other agencies until a new abundance 
of moisture called them out of their trance. As 
zygotes, they exist in the Nostoc today. 
The first plants were non-sexual and propa- 
gated by cell division. ‘They were therefore

ities for racial improvement and differentia- 
tion were opened up. The Mosses and Ferns
