Horticultural Society" : — " The bottom 

 of the border is gently sloped from the 

 houses to the extreme edge, where is 

 built a box-drain (a on fig. 415) extending 

 the whole length of the border, as shown 

 in the section. This drain is 1 foot 

 square, the top of it being level with 

 the bottom of the border. When this 

 was completed, dwarf walls, marked c, 

 were built across the border, 3^ feet 

 apart, in the pigeon-hole manner. On 

 the top of these walls were laid rough 

 flags. These in reality form the bottom 

 of the border ; and upon these is placed 

 about 6 inches of broken stones and 

 bricks, marked d, covered with turf, with 

 the grassy side down, to prevent the 

 soil mixing with the stones. There 

 are flues or chimneys at each end of 

 the border and centre, communicating 

 with the drains in the bottom, as shown 

 in the section, marked b. The tops of 

 these flues are nicely made of stone, 

 10 inches square, through which is cut 

 a hole of 6 inches square, into which is 

 inserted a plug, of a wedge-like form, so 

 as to fit tightly, but removable at plea- 

 sure. These flues are about an inch above 

 the ground. At the back of the border 

 are placed cast-iron pipes (marked e) per- 

 pendicularly, and also communicating 

 with the drains underneath. Those, being 

 higher than the flues in front, cause a 

 motion in the air beneath the border. 

 / / are the boilers. After a long continu- 

 ance of rain, the plugs in the flues in 

 front are taken out, thereby creating a 

 great circulation of air, and thus to a vast 

 extent accelerating the proper drying of 

 the borders, which is deemed of much 

 importance." The object of the inventor 

 of this border, no doubt, was to get rid of 

 superfluous water, and at the same time 

 to admit a sufficiency of air naturally 

 warmed by the sun; and by the same 



judicious arrangement, he has it in his 

 power, during cold or damp weather, to 

 exclude the air altogether. By a reference 

 to the section, it will be seen that we 

 have carried the drain- 

 age and ventilation 

 under the border with- 

 in the house, and 

 shown the means of 

 supplying it with air 

 from behind the back 

 wall. By placing hot- 

 water pipes in the front or back drain, 

 the whole border might be warmed when 

 deemed necessary.
