pits of any sort are preferable to dung beds, and this one, if 

 partially sunk under the ground-surface, or surrounded with a 

 neat wall as high as the perforations in the side walls, will 

 have a neat and respectable appearance. 



The Edmonstone pit is calculated either for the cultivation 

 of melons, cucumbers, or young pines, and may be understood 

 by a glance at the accompanying sketch. Its length is eighteen 



and a half feet, and six 

 feet in breadth; the 

 height of the back wall 

 is five feet, and that of 

 the front one, three feet 

 nine inches. The heat 

 is supplied by linings of 

 eg J .| hot dung, which sur- 



round the pit three feet 

 deep and two feet three 

 inches broad, and is 

 separated from the sur- 

 rounding ground by a 

 nine-inch wall as high 

 as the ground-surface, 

 which wall is finished 

 with a course of hewn 

 stone on the top. The 

 linings are covered with 

 a wooden cover, which 

 is sujiported by the 

 above wall and front 

 wall of the pit, and 

 which prevents the 

 dung of the linings from 

 being chilled by rain 

 or cold, and completely 

 hides all that is so of- 

 fensive to the eye in 

 ordinary hot-beas and pits where the lining is exposed. This 

 pit is in very general use in Scotland, and is described in a 

 communication in the CaL xlort. Trans. To these may be
