 the back part of sashes, which can be made to slide 

 either up or down for ventilation ; while, in addition, 

 there are boxes let into the sides of the front and back 

 walls, through which ventilation may also be given. It 

 is heated from a wrought-iron saddle boiler, and, as will 

 be seen in the section (fig. 5), there are seven rows of 

 4-inch hot-water pipes, with some evaporating troughs 

 cast on the pipes, and fitted in the rows for top heat. 

 Both amateurs and gardeners will find a forcing pit -of 

 this description most useful. The length is 65 feet 

 by 12 feet, and, as far as my memory serves me, the 

 whole cost was about £150.

and all kinds of erections for horticultural purposes, I
