18. An Account of a Method of obtaining very early Crops of the 

 Grape and Fig. By Thomas Andrew Knight, Esq. F.R.S. Pre- 

 sident. Read March 1. 1825. 



Mr. Arkwright has proved that vines, of which the wood 

 and fruit have ripened late in one season, will vegetate late in 

 the following season, under any given degree of temperature ; 

 and Mr. Knight has shown the converse of this proposition to 

 be equally true. A Verdelho vine, growing in a pot, was placed 

 in the stove early in the spring of 1823, where its wood be- 

 came perfectly mature in August. It was then taken from the 

 stove, and placed under a north wall, where it remained till 

 the end of November, when it was replaced in the stove, and 

 it ripened its fruit early in the following spring. In May it 

 was again transferred to a north wall, where it remained in a 

 quiescent state till the end of August. It then vegetated 

 strongly, and showed abundant blossom, which, upon being 

 transferred to the stove, set very freely ; and the fruit having 

 been subjected to the influence of a very high tempeiature, 

 ripened early in February. 



The white Marseilles fig, and figue blanche, which very 

 closely resemble each other, succeed most perfectly under 

 similar treatment ; and if the trees be taken from the stove in 

 the end of May or beginning of June, and placed under a 

 north wall till September, and be then again transferred to 

 the stove, they will begin to ripen their fruit in January or 

 February, and continue to produce it till the end of May or 

 the beginning of June, when they should be again removed 

 from the stove. 



19. On the Culture of the Pine Apple. In a Letter to the Secre- 

 tary. By Mr. William Greenshields, Gardener to Richard 

 Benyon de Beauvoir, Esq. F. H. S., at Englefield House, in 

 Berkshire, Corresponding Member of the Horticultural Society. 

 Read April 19. 1825. 



The following directions are for the management of pine 

 plants that are intended to show their fruit eighteen months 

 after removal from the parent plant. In the end of August, 

 or beginning of September, prepare a pit for the stock of crowns 

 and suckers. A bed 24 by 6 feet will hold 400 plants. 

 Stick in the crowns and suckers in rows, as thick as they will 

 stand, and about one inch and a half deep. Keep to 70°, and 

 shade during hot sunshine. Through the winter, apply dung 

 linings, to keep the internal air between 50° and 60°, and pro- 

 tect the glass with mats during the night. If the bed should 

 get very dry, give a gentle watering over the surface. No 

 other care or attention will be necessary till March, the roots
