SECT, II. 



*>f metals, and to u the place of fapphires ; and there is 

 nothing hid from the heat thereof" 



What bleffings does this bounteous planet pour 

 On the glad heart of man, when rolling round 

 Kis azure road, he fcatters as he flies, 

 To warm his raptur'd bofom, light and joy ! 



Newcomb. 



The sun is the fountain of light. This glori- 

 ous i obj eft of creation, as a luminary, gives chearful- 

 nefs both in nature and appearance to all things : If 

 light is not fo neceflary to our exiftence as heat, life 

 would yet be miferable without it. 



As to vegetation, we may obferve, without light 

 plants get always fickly, and would not exift long if 

 deprived of it. Light, philofophically confidered, is 

 half their nourishment. All plants turn to the light 

 as to a powerful attraction, or, as ff confcious how 

 necefTary it is to their exiftence. Light at the fame 

 time that it heats, doth wonderfully rarify and raife the 

 fap. It is the fame with J&ther, and it fo mixes with 

 other bodies, as to enter into their compofition, and 

 encreafe their weight. The aromatic flavour of veget- 

 ables feems to depend upon the fun's light as much as 

 colours do. 



The phyfical properties of that eiherial fubftance, 

 which is fo fubtle and pervading as light, we may well 

 believe to be various and wonderful, though incon* 

 ceiyable. 



Behold the light emitted from the fun, 

 "What more familiar, and what more unknown ? 

 While by its fpreading radiance it reveals 

 All nature's face, it ft ill itfelf conceals. 

 How fwift flr effulgent emanations fly- 

 Thro* the blue gulph of interpofing fky ! 

 Millions of miles j fo rapid is their race 

 To cheer the earth, they in few moments pafs.
