NE'RTUM. Oleander. (From neros, moist ; referring 

 to their native places of growth. Nat. ord. Dogbanes 

 [Apocynaceae]. Linn. s-Pentandria, i-Monogynia.) 



Notwithstanding the beauty of the Oleander, it is one 

 of the most virulent of vegetable poisons. Beautiful 

 greenhouse plants, but which require a higher tempera- 

 ture 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.

 divisions. Loam, leaf-mould, and plenty of sand.

NESTS' A. (The name of a sea-nymph. Nat. ord.

Nearly hardy, evergreen shrubs, except A T . triftora, a 

 stove perennial herb. Divisions in spring, as fresh growth 

 commences ; cuttings of young shoots in sandy soil, 

 under a bell-glass ; sandy loam and fibrous peat. Winter 

 temp., 45 to 55 ; summer, 60 to 80. The half-hardy 

 ones require the protection of a wall or pit in winter.

NETOU'XIA FORMO'SA. See NECTOUXIA FORMOSA. 



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 connection with that, it may be ob- 

 served, that it is not altogether immaterial of what sub- 

 stance netting is formed. Worsted is to be preferred, 

 not only because 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 of 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 efficient in keeping 

 similar insects from intruding into rooms if there are no 

 cross lights. If there are windows on different sides of 

 the room, and it is to be presumed, therefore, also in a 

 green or hothouse, 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 gardener must when covering his trees. Dis- 

 appointment, therefore, should be avoided, when order- 

 ing new nets, by stating the size of the surface which 

 has to be covered. This may be done without any fear 

 of imposition. 



Mr. Richardson, net-maker, New Road, London, in- 

 forms us that one cwt. of old mackerel-net, weighed 

 when quite dry, will cover 800 square yards ; and one cwt. 

 of old herring-net (smaller meshes) will cover 600 square 

 yards.
