AQUATIC ADJUNCTS OF A ROCK GARDEN, iii 



with one side open to a raging snowstorm, will perhaps 

 enjoy it rather more then than on a day of blazing 

 summer heat, when the water sparkles joyously in 

 the sun, the dragon-flies expand their brilHant wings, 

 and the Water Lihes open their exquisite flowers on 

 the surface ; but the ordinary mortal will like it best 

 under genial conditions. Just as the holiday maker 

 flies to the sea when the thermometer rises to 85° in 

 the shade, so the garden-lover turns his footsteps 

 towards the bog-garden or Lily pool when heat op- 

 presses the garden. 



The bay system of making a rock garden has been 

 referred to. The earth is ridged round an enclosure, 

 and stones placed in position. The central space in 

 the bay provides the most favourable place for making 

 a bog garden. Poor chalky soil will not do here. 

 Leaf mould and peat are required. If the soil is dry, 

 and of a character unsuitable for development into 

 a damp " mould," it will be necessary to remove it 

 to a depth of some eighteen inches, and substitute 

 the other ingredients named. If the natural soil is 

 a good loam it wiU suffice to add peat or leaf mould 

 liberally. This soil must be kept moist by some means 

 or other. I have myself arranged matters by forming 

 a cemented pool to take the roof water, and utilising 

 the overflow from this for a bog bed. The plan has 

 necessitated cutting a trench across a drive and carry- 

 ing it through a border to the lowest site, but the 

 expense entailed was very small, for it does not take 

 a couple of navvies long to open a few yards of trench, 

 and piping costs little.
