 A, being just pushed into the soil, while if the roof glass 

 is fairly large, it can be raised high enough above the 

 sides to give ample ventilation, without allowing the 

 rain and wind to drive in to any damaging extent.

For various reasons I was obliged to make a path

 and start the rockery from the inside edge of this. 

 I took considerable care to arrange that the outline
