their stagnation. The climate of the north of Italy is similar 

 to that of the north of China, and it was there, in the neigh- 

 bourhood, we believe, of Milan, that Mr. Clare tried the ex- 

 periments, of which this paper communicates the result. 



In Italy, in the spring of 1822, some seeds of iVelumbiums 

 were planted in a large tub, half filled with earth, covered 

 with tiles, and then watered, which was changed every second 

 day. The seeds came up well, but the plants were soon 

 covered with confervae, and rotted away. Seeds were then put 

 in a large pot, and plunged in a small stone basin, in which 

 there was a fountain always playing, and the water constantly 

 agitated, from having to supply a large garden. Here the 

 plants produced leaves two feet wide, abundance of flowers, 

 and a great quantity of seeds. They were left every winter 

 in the open air, and have since continued to bear abundantly. 

 N. luteum, in the Botanic Garden of Pavia, lived from year 

 to year but never flowered, till, the tub becoming leaky, it be- 

 came necessary to turn on a perpetual supply of running 

 water, soon after which the plant sent up flowers and ripened 

 many seeds. 



In England, ^elumbiums must have the protection of glass ; 

 but Mr. Clare thinks it " very possible, that at some future 

 time, hybrids may be obtained from them, and our own beau- 

 tiful -/Vymphae'a alba, odorata, and cserulea, or others, which 

 seed freely in this climate." In the south of Europe, he thinks, 

 TVelumbiums may possibly become so common as that the 

 seeds will be exposed for sale, as those of the Spanish 

 chestnut. 



This paper, in connection with that of Mr. Stewart on the 

 same subject, shows the great difference to plants between 

 stagnant water and water in a state of motion, and that the 

 probable necessity of procuring this motion will ever render it 

 difficult to cultivate in gardens plants of the sea.

Tweed Tcoseberry Strawberries. — Mr. G. Meredew, gar- 

 dener to C. Calvert, Esq., of Whitton, plants two runners in 

 a pot early in July ; the pots are placed in a shady situation 

 till the end of the month ; they are then plunged in an open 

 quarter of the garden till the end of September, when they 

 are transported, one plant in a pot ; they are now set under 

 a frame with a little bottom heat till the end of November, 

 when they are taken into the pine stove, and ripen their fruit
