48. On the Culture of Nelumbium speciosum. By M. Liibeck, 

 Director of the Gardens of Comte Karrach, at Bruck on the 

 Leitha. 



After the points of the seeds are carefully opened, they are 

 put into a glass of water, where they soon germinate; they 

 should then be planted in pots, half-filled with loamy soil 

 (taken from places where iVymphae^a alba, &c., grow), and 

 filled up with water. This being done in spring, the plants 

 will be very strong-grown against the winter, when no water 

 should be allowed to remain in the pot, but only given 

 from time to time. When they begin again to grow, in the 

 following spring, they are to be shifted into other pots, and 

 treated as in the former year. In the third year they will 

 require a large jar of about 2 ft. high, and IJft. wide. The 

 water must be occasionally changed, but without disturbing 

 the plant, which is easily effected by a tap in the jar. The 

 plants will then grow very vigorously, and flower beautifully. 

 A plant treated in this manner produced a scape 6 ft. high, 

 and also ripe seeds. M. Liibeck recommends this plant, 

 and its varieties, as an ornament in a water basin in conser- 

 vatories ; which basin should, however, not be square, but 

 circular, to allow the roots to run freely round it, which the 

 strongest roots of this plant always do. 



49. On Cleft-Grafting the Vine. By M. Linne. 



This has been practised with perfect success at the royal 

 gardens at Potsdam. The grafting is done as near the 

 ground as possible, and grafts are chosen to be equal in 

 diameter to the stock, so that both sides of the bark of the 

 graft and of that of the stock may fit exactly together. After 

 being tied, the. soil must be raised to cover the graft, and 

 when the stock is too high this may easily be accomplished 

 by a flower-pot filled with earth. By this way of engrafting, 

 grapes were obtained the first year as large and plentiful as 

 on any other vines. 



54. Extract from the Transactions of the Society at the Meeting of 

 October 10. 1824. 



The gardens in Riga, M. Zigra stated, are chiefly laid out 

 in the English and Dutch styles, and consist principally of 

 fruit and kitchen gardens. In several private gardens are 

 large glass-houses, in which pines, peaches, and grapes are 

 grown plentifully. The extensive forcing-houses of the Rus- 

 sians supply abundance of asparagus, melons, cucumbers, 

 and other vegetables, very cheap, and at a season when they
