THE FLOEAL WOELD AND GAEDEN GUIDE. 



The plan of under-ground pipes for sup- 

 plying water direct to the roots is one we 

 have adopted in the culture of ranuueu- 



is an improvement, and is wholly accom- 

 plished on the surface. The tiles are one 

 foot long, and made as represented, a, being 



lusos, much to the benefit of the plants 

 and the lessening of lnbour, as, by turning 



a tap, the bed could be saturated at any 

 time by the flow of the fluid from the 

 pipes j but this plan of Mr. Hodgkinson's

 not all perforated on the top as shown at 

 a, but, at distances of three or four yards, 

 there is such a perforation, large enough to 

 receive a sixty-sized pot. They are laid on 

 the surface, in a line, between two rows of 

 plants, and, the water or liquid manure 

 being poured in at the orifices, runs along 

 the pipe, and passes through the small 

 holes in the tile direct to the roots of the 

 plants. Thus one important purpose is 

 accomplished ; but another advantage is, 

 that the tile screens the roots of the plants 

 from the heat of the sun, and preserves a 

 moistness in the soil long after the liquid 

 has drained away, and the plantation is
