404 FORCING DEPARTMENT. 



LATER FORCING PIT. 



The prefixed Plate, No. 24, is illustrative of the 

 principle and construction of the pit intended for forc- 

 ing Melons, Cucumbers, &c. at a more advanced 

 period of the year, when a greater degree of moisture 

 is essential to the well-being of the plants than is 

 necessary at an early period. This pit is construct- 

 ed with four-inch brick work all round, and with nine 

 inch piers, at four feet apart, in order to strengthen 

 the walls. The walls also along the centre, together 

 with the back, front, and end walls, to the depth of 

 two feet, are honey-combed, similar to the back of 

 the two last mentioned pits, which will be seen by 

 the annexed Section. 



This pit is also well adapted for the growth of 

 young Pine plants in the Summer months ; the ex- 

 terior walls being honey-combed all round, admit 

 rather more moisture in the Winter season, than 

 those which are furnished with a cavity in front ; 

 but in other respects they are equally serviceable. 

 This pit is six feet six inches wide, seven feet deep at 

 the back, and five feet deep in front ; and is divided 

 at every three or four sashes in breadth into compart- 

 ments, to suit the different succession of Melons, 

 Cucumbers, &c, and to keep the various kinds in 

 separate divisions.
