NATURE AND BOOKS. 21 



have I gone in three steps from May dandelion to Sep- 

 tember apple ; an immense space measured by things 

 beautiful, so filled that ten folio volumes could not hold 

 the description of them, and I have left out the meadows, 

 the brooks, and hills. Often in writing about these 

 things I have felt very earnestly my own incompetence 

 to give the least idea of their brilliancy and many-sided 

 colours. My gamut was so very limited in its terms, 

 and would not give a note to one in a thousand of those 

 I saw. At last I said, I will have more words ; I will

 old time, and turned to again ; some I read for the first 

 time, some translated from the German, and so on. It 

 appeared that, experimenting with physical colour, tan- 

 gible paint, they had found out that red, yellow, and 

 blue were the three primary colours ; and then, experi- 

 menting with light itself, with colours not tangible, they 

 found out that red, green, and violet were the three 

 primary colours ; but neither of these would do for the 

 dandelion. Once upon a time I had taken an interest
