18 in. for sides as for ponds, and finished with an 

 inch of cement. The inner wall should slope 

 outwards slightly to give easy expansion to water 

 in the event of its freezing. 



Four ft. is ample depth for any basin. When 

 water lilies are required they should be planted in 

 boxes, for which Diagram 69 gives a good pattern. 

 ^ It is 2 ft. every way out- 



side measurement, and put 

 together with strong square 

 corner pieces which project 

 at the bottom about 3 in. 

 This enables a free circula- 

 tion of water, and makes 

 DIAGRAM 69. the boxes easier to handle 



by passing ropes between 



the legs. The wood should be oak, teak, or other 

 hard wood, and be tarred as well. There should 

 be holes in the bottom for drainage, and the soil 

 is made up with drainage material and rough stuff 

 in exactly the same way as for ordinary potting, 

 except for a finish of about 2 in. of clean gravel 

 on the top. 



Copings of some sort are necessary. A very 

 simple finish can be obtained directly with the 

 material used. The concrete basis should be 

 roughly moulded to a curve, and the final shape 

 worked up with the cement by means of a template. 

 Tn making a circular basin a strong stake is driven 

 in for the centre, and a piece of wood nailed to
