 (inOG). Nos. ]■',, pp. 55S-.')6G, pU. S, fig. 1; 16, pp. 743-754, pl- 1; 5 (1906). No. 17. 

 lip. l.'/O-l'iS. figs. 2). — Obsei'vations and experiments on various plants are 

 rei)orted which lead to the conclusion that in regions of little cloud jind exces- 

 sive sunlight, as is the case at Pretoria, Transvaal, the early sun's rays are 

 especially active in stinuilating the grow^th of plants and indicate the desira- 

 bility of so planting croi)s that they may utilize to the fullest extent such rays 

 .•ind be protected from excessive sunlight. 



The author states the belief "that, besides rain. heat, soils, and .-ill the well- 

 recognized factors which enter into the question of growth, there are some subtle 

 intluences at work which have hithex'to been little, or not at all. taken into 

 accoimt." 



In conuuenting upon these conclusions H. Ingle and I. B. Pole Evans discuss 

 the principal factors influencing plant growth in their bearing upon the deduc- 

 tions set forth, concluding that the results upon which the deductions are based 

 " may be explained liy the effects of temperature changes, and without attribut- 

 ing any occult influence to the morning sunshine per se. . . . 



" One important conclusion may be dediiced from the considerations discussed 

 in this review — that many plants, would be benefited by being shaded from the 

 hot midday sun. thus often preventing them from being heated above their 

 maxinuim temi)erature for growth. . . . 



" It is probable that sunrise light contains a sufticienc.v of orange and yellow 

 rays to pi'oduce rapid carbon assimilation, while the blue and violet rays, which 

 tend to reduce growth, are relatively deficient. 



" The unscreened plants, receiving such rays at a period when their tempera- 

 ture is favorable for the performance of their vital functions, thus have an 

 advantage over their screened neighbors, which do not receive such strong light 

 until later in the day. when their temperature is quickl.v raised to a point not 

 so favorable for assimilation, but more favorable to the respiratory processes by 

 which their tissues are oxidized and diminished."
