COLORATION BY SUNLIGHT ii 



7. If all countries had one quality of 

 forage, all horses would have one strength. 



8. It follows that the study of light, heat, 

 moisture, landscape, soil, and food should 

 explain the origin of the wild types of horses. 

 Our breeds are got by crossing from these 

 varieties. 



If, therefore, the facts which we find out by 

 study shall correspond with the reader's own 

 experience of horses, no further proof is 

 needed ; but if they fail to appeal to the 

 reader's sense and judgment, no balancing of 

 proofs upon a point of falsehood will save a 

 useless book from the flames which await 

 waste paper. 



PART I. COLORATION BY SUNLIGHT. 



The best way to train one's sense of colour 

 is to dabble in landscape painting. At first, 

 one feels that there must be a personal Devil, 

 but with luck the colours begin to clear, show- 

 ing that the tones of night and the deep sea 

 are based on indigo, while those of the day 

 are blue, red and yellow variously mixed. 

 The blend of blue and red is violet ; the mix- 

 ture of blue and yellow gives us green ; and 

 if we want an orange we use red and yellow. 

 The blending of all seven is sunlight in theory, 

 but makes mud in practice.
