THE ARTIFICIAL ROCK GARDEN 6i 



be obtained in a day's walk in a wild and rocky 

 country than in a week's reading, and a few 

 studies of natural rock made with a camera 

 will prove of untold assistance. The chief 

 difficulty is found when one comes to try to 

 reproduce and adapt these pictures on the 

 reduced scale : such at least has been my 

 experience. 



Those who, undeterred by expense, or the 

 magnitude of the undertaking, wish to make 

 such a garden, but have only sloping ground out 

 of which to form it, will have to dig out the 

 valleys and raise the hills. To such I should 

 recommend working on lines somewhat similar 

 to those laid down for the valley, only, of 

 course, on a very much larger scale, the valleys 

 wider in proportion to their depth and the 

 hills with a more gradual incline. To get the 

 soil in its proper place and to avoid burying 

 what is wanted on the top and to distribute it 

 evenly will be even more difficult than before. 

 For while alpines require at least 12 inches of 

 good soil as a general rule, the shrubs in the 

 valleys require far more, and great ingenuity 

 will have to be exercised to provide all this.
