PLANTS THAT PRODUCE LIGHTS 131

 tion of source and supply here either the plant 

 giving of its phosphorescence to the insect, or vice 

 versa or whether there is merely an attraction of 

 likes; or whether there is indeed any connection 

 between the kindred powers of insect and plant, and 

 this intimate association, is a question that yet re- 

 mains to be answered. 



When the Creator made light, that was not 

 enough ; there must be eyes to appreciate this light ; 

 so He created animals with eyes, and human be- 

 ings with eyes, and lastly, although the average 

 person knows it not, plants with eyes, that they too 

 might worship this great work of their Maker. 



The number of plant eyes is legion. They are 

 usually tiny cells located in the epidermis of the 

 leaves, and occasionally on the leaf -stalk. Numer- 

 ous experiments have been made by Dr. Haber- 

 landt which prove conclusively that the eyes of 

 many species of plants are capable of detecting 

 as slight shades of variation in light as are those of 

 man. This is amply proved by the fact that cer- 

 tain plants, like the vetch, pea, or lentil, may be so 

 influenced in their earliest stages of growth that 

 they deliberately turn toward lights. 



The scientific world now thoroughly recognises 

 that plants have eyes, and actually see! Not only
