WALLING. 



The top course of brick should be two or three inches below the ground level, 

 so that the green sod will cover all trace of masonry. After the walls are 

 built, finish off with a facing of Portland cement. The bottom may be made of 

 concrete or broken bricks well grouted in, and afterwards finished off with a 

 layer of Portland cement. The division walls 

 for Nelumbiums may be made of four-inch 

 work, if the sections are not large ; otherwise 

 build them eight inches thick. These need not 

 be built to the surface, as they are intended 

 only to confine the roots. 



An overflow pipe is essential, and an outlet 

 is very handy, but if Water Lilies and Nelum- 

 biums are to be planted out, the water will be 

 kept in the pond all winter ; there will, how- 

 ever, be times when transplanting, renewal of 

 soil, etc., will necessitate the water being 

 drawn off, and then the usefulness of an outlet 

 will be apparent. A drain must be provided to 

 carry off the water, and one or more outlets 

 made, according to the size of the pond. A 

 two-inch pipe, or three-inch pipe, of malleable 

 iron, built into the solid masonry at the bottom, 

 can be made to answer for outlet and overflow. 

 An L fitting, attached to this pipe, should be 

 level with the bottom, and to this may be joined 

 an upright piece of pipe that will reach the 

 surface ; this may be in two pieces, one of 

 eighteen inches, another of six inches. If, 

 after planting, it is desirable to have but six 

 inches of water in the pond, remove the top 

 section of pipe, which can be replaced when

A most useful tank is one built of either 

 brick work or concrete, twelve feet long, five feet six inches wide, and from 

 eighteen to twenty inches deep. This will afford room for six or eight tubs 

 in summer, and will prove one of the best tanks for wintering stock ; using a 

 frame and sashes, and in severe weather a shutter or covering of salt hay or
