132 WALL AND WATER GARDENS 



Where tubs of aquatic plants are not sunk in the 

 ground their form seems to suggest some rather 

 symmetrical arrangement, but in this case their dis- 

 position would entirely depend on what local circum- 

 stances would offer or demand. 



The little bog -garden will probably belong to 

 persons of small or moderate means, to whom it is 

 an object to avoid costly labour. Many an owner

 that the barrel could be changed if necessary. The 

 piece of rock-wall would be buttressed back on each 

 side of the barrel and a little rough arch made in 

 front for hand access to the tap. Then somewhere

 upper end of the pipe. The dark hole under the
