the temperature desired, slates were put from shelf to shelf, 

 so as to cover the whole space, and the intervals between the 

 pots were rilled with tan. This last operation will not be ne- 

 cessary, unless the heat has declined very much, and then 

 care must be taken that the tan does not get so warm as to 

 burn the roots of the plants. Leaves may be substituted for 

 tan, if more convenient. Mr. Breese has obtained in the 

 house treated as described, both Pines and Grapes superior to 

 what he has seen grown by fire heat. He thinks some plan 

 might be devised to avoid the trouble of moving the plants 

 every time the dung requires turning. 



Mr. William Ross sent to the Meeting, from his Nursery 

 at Stoke Newington, on the 15th of October, bunches of the 

 Black Damascus Grape, the blossoms of which had been fer- 

 tilized by the pollen of the Royal Muscadine, and on the 5th 

 of November Mr. Ross communicated the particulars of the 

 process. He observes that the blossoms of the Black Da- 

 mascus Grape are known to set very imperfectly, even in the 

 stove, and of course more imperfectly in the vinery or open 

 air. He had a plant of this variety on the open wall, which, 

 for many years, invariably failed to set its fruit, producing 

 only three or four very large berries on a bunch, whilst the 

 remaining blossoms proved abortive. With the view to 

 remedy this defect, he caused, when the Vine was pruned, 

 several shoots of it to be trained in amongst shoots of a Royal 

 Muscadine growing near it on the same wall, so that the 

 blossoms of the two plants should come in contact with each 

 other. This had the desired effect ; those bunches which 

 were mixed with the Muscadine all set well, while the rest of
