Fig. 98.— Cross section of an attractively edged pool of concrete with a supplementary, 

 smaller pool and waterfall provided at one end for added effect 



larger than a walnut. By adding water, a little at a time, and pound- 

 ing with a wooden maul reduce the whole to a putty-like consistency; 

 then start moistening and pounding the second load, etc. Having re- 

 duced sufficient clay to a proper consistency spread it about three inches 

 thick over the sides and bottom of the pool, beating it down as laid. 

 In treating the margins of such a pool it is best to lay rocks in the 

 clay down the bank to about a mean water level; this will prevent a 

 gradual washing away of the clay at the water's edge. If water plants 

 are to be used in the pool put in a layer of rich soil twelve inches to 

 fifteen inches deep; then let in enough water to cover this layer about 

 three inches deep and let the pond stand for a few days to warm up 

 before planting. 



PLANTING 



In concrete or brick pools it is necessary to plant in some sort of 

 a receptacle, either fixed or movable, the size ranging from one by two 

 feet to two by four feet and the depth from ten to twelve inches. If 

 these pockets are made of brick, do not cement the joints, but merely 

 build a loose wall. Tubs make good receptacles in which to plant. 



WINTERING 



Hardy Water Lihes will take care of themselves, and natural ponds 

 may remain undisturbed. The more tender varieties planted in loose 

 tubs may be removed to a cool cellar, or, if they cannot be removed, 

 drain off the water and cover the plants with hay, leaves, etc., and 

 place a few planks over the top. Really tender day bloomers are quite 

 difficult to winter over, and unless the grower understands the subject 

 thoroughly it would not be advisable for him to attempt the growing 

 of these tender sorts.
