put into small sized pots, and plunged in fresh tan, with a 

 good bottom heat kept up by dung linings. They are shaded 

 from the sun in the heat of the day, and a little air given 

 until they begin to grow, which will be in about three weeks 

 from the time they are potted. The above operation may be 

 performed any time between the months of February and 

 September. 



Mr. John Breese, Gardener to Sir Thomas Neave, 

 Bart, at Dagnam Park, Essex, communicated to the Meeting, 

 on the 17th of September, an account of his method of 

 growing Pines with a bottom heat of dung, in a house in which 

 Vines for early Grapes were also to be forced. The house 

 in which he made his experiment is forty-four feet long by 

 seventeen feet wide, and the pit within it is thirty-six feet 

 long by nine feet wide. He placed strong bars across the 

 pit, and on them rested six rows of moveable shelves length- 

 ways, so as to hold six rows of Pine plants, twenty in each 

 row, the bottoms of the pots being about six inches below 

 the curb. From these shelves to the bottom of the pit is 

 about three feet, two feet and a half of which depth was 

 filled up with rank dung from the stable, and the other six 

 inches with old exhausted dung from the linings of Cucumber 

 beds. The Pine plants were then placed on the shelves, and 

 the steam from the fresh dung rising through the exhausted 

 dung on the top, entered the house sufficiently sweet for all 

 the purposes of vegetation, not only of the Pines but also for 

 the Vines, which are trained to the rafters. When the heat 

 declined much, it was renewed by turning the dung once a 

 month and adding a little fresh, and when this failed to give
