the 19th of February, a Description of Pine-Pits, worked 

 without fire or dung heat. The pits are somewhat on Mac 

 Ph ail's plan, but adapted by Mr. Dall to the culture of 

 Pines; the outside of the pits is surrounded with a mound of 

 leaves five feet and a half thick, five feet high in front, and 

 seven feet at the back. As the leaves settle, additions of fresh 

 leaves are made, to keep up the height of the mound, which 

 requires neither turning nor changing for a twelvemonth. After 

 that period, the leaves are removed for forcing Asparagus, 

 Sea Kale, &c. ; and in the third year they become vegetable 

 mould. The length of the Pinery is one hundred and sixty 

 feet, and there are seven hundred one-horse cart loads of 

 leaves gathered yearly, which produce three hundred cubic 

 yards of vegetable mould. From the stock of Pine plants 

 (which are in number from five to six hundred,) there are two 

 hundred and fifty fruit cut annually. At the time of making 

 the communication, Mr. Dall had practised this mode of 

 raising and fruiting Pines for four years, and has since conti- 

 nued it with the greatest success. 



Mr. James Smith, Gardener to the Earl of Hopetown, at 

 Hopetown House, in Scotland, communicated, in a Letter to 

 the Secretary, read at the Meeting on the 19th of March, a 

 method for forcing Rhubarb. In the last week of December 

 he takes up roots of the Rheum hybridum, with the fibres 

 as little broken as possible, and plants them in a light soil, in 

 boxes three feet long, one foot eight inches wide, and one foot 

 three inches deep, as close together as possible. The boxes 

 are placed in a Mushroom-house, or other dark room, and wa- 

 tered occasionally. If the temperature of the place be from
