To those who may not immediately comprehend the principle of the 

 annexed pit, the follo\sing explanation will he of use. The inventor, 

 W. Atkinson, Esq., being aware of the danger which often attends the 

 admission of rank steam into forcing-pits, directed his attention to the 



subject, with a ^iew to remedy its defects, and the pit before us is the 

 result of his ingenuity. The pit is sunk under the ground level about 

 one-half of its height, as shown in the sections, and is heated by hnings, 

 apphed in the usual way, round its sides and ends. The interior is filled 

 with either dung, tan, or leaves, the latter in all cases to be preferred. 

 The heated air from the linings, wliich should be of fresh unfermented 

 dung, enters through the back wall, between the open com'ses of brick- 

 work ; but the rank steam is prevented at the same time from entering 

 immediately to the plants, as it is admitted into the cavity between the 

 walls and a partition formed of large AYelsh slates set edgeways, where it 

 is confined or let out at the pleasure of the cultivator, as this cavity is 

 covered over at top with narrow slips of slate or boarding, which can be 

 left on or removed at pleasure. When the intention is to admit the heat 

 unaccompanied with steam, this covering is kept on, and the heat finds its 

 way into the bed through the slates ; but when it is desirable to admit damp 

 vapour or steam, the covering is partially or wholly removed. With
