Notwithstanding the beauty of the Oleander, 

 it is one of the most virulent of vegetable poisons. 

 Beautiful greenhouse plants, but which require a 

 higher temperature to start them in the spring. 

 Cuttings of shoots, getting firm, in sand, under a 

 bell-glass, and kept warm ; cuttings a little older 

 do well in phials of water, also kept warm; peat 

 and loam, enriched with cow-dung and leaf- 

 mould. Winter temp., 35 to 48; summer, 60 

 to 75. The shoots made this season should 

 bloom the next, if well ripened.

 as fresh growth commences; cuttings of young 

 shoots in sandy soil, under a hell-glass; sandy

NETTING is employed to prevent the 

 radiation of heat from walls, and the 

 rude access of wind to trees grown upon 

 them, as well as to prevent the ravages of 

 birds. 



Netting is a very effectual preventive of 

 cooling, for reasons which will be stated 

 when considering Screens generally ; and 

 in connexion with that, it may be ob- 

 served, that it is not altogether immate- 

 rial of what substance netting is formed. 

 Worsted is to be preferred, not only be- 

 cause it is the most durable, but because it 

 is the best preventive of a wall's cooling. 

 We have found the thermometer under 

 a hemp net sink, during the night, from 

 2 to 4 lower than that under a net of 

 worsted, the meshes being small and ot 

 equal size in both nets. This can only be 



because worsted is known to be a worse 

 conductor of heat than hemp; and, not 

 absorbing moisture so easily, is not so 

 liable to the cold always produced by its 

 drying. Netting will also exclude flies 

 and other winged insects from the fruit 

 against walls, although the meshes are 

 more than large enough to permit their 

 passage. Why this is the case is not very 

 apparent ; but the netting is equally effi- 

 cient in keeping similar insects from in- 

 truding into rooms if there are no cross 

 lights. If there are windows on different 

 sides of the room, and it is to be pre- 

 sumed, therefore, also in a green or hoU 

 house, nets would not be so efficient. 



One hundred square yards of netting, 

 according to some merchants' mode of 

 measuring, will not cover more than fifty 

 square yards of wall, for they stretch the 

 net, first longitudinally, and then laterally, 

 when making their measurement, and not 

 in both directions at once, as the gar- 

 dener must when covering his trees. Dis- 

 appointment, therefore, should be avoided, 

 when ordering new nets, by stating the 

 size of the surface which has to be co- 

 vered. This may be done without any 

 fear of imposition. 



Mr. Eichardson, net-maker, New Road, 

 London, informs us, that one cwt. of old 

 mackarel-net, weighed when quite dry, 

 will cover eight hundred square yards; 

 and one cwt. of old herring -net (smaller 

 meshes) will cover six hundred square 

 yards. Mr. Hulme, of Knutsford, has 

 sent us various specimens of his nets and 

 open canvass for inspection some made 

 of woollen and others of hemp : the last 

 does not shrink after being wetted like the 

 woollen. Mr. J. Haythorn, of Nottingham, 

 has also sent us specimens of his excel- 

 lent hexagonal netting.

NEW ZEALAND SPINACH (Tetragon ia

 for summer spinach, being of more deli-

 whole summer.
