may require, according to the sizes they are likely to attain. 
In their subsequent management they should be kept closely 
nailed to the wall, and part cut out of them, when they become 
too crowded. The surface of the border should be loosened 
twice or thrice each season, but no manure dug in. The 
plants should be selected from some of the following genera: 
Acacia, Arbutus, Banksia, Beaufortia, Callistachys, Callis- 
temon. Camellia, Cassuarina, Ceanothus, Colletia, Duvaua, 
Edwardsia, Eucalyptus, Grevillea, Hakea, Leptospermum, Mel- 
aleuca, Metrosideros,Pillosporum,Pomaderris,Sollya,Veronica, 
Viburnum, &c. Until the plants cover the wall, vacant spaces 
may be covered with some of the free-growing greenhouse 
creepers, such as Cobseas, Lophospermums, Maurandyas, Tro- 
paeolums, &c. The soil, as well as the situation near the wall, 
will also be well-suited to the Gladiolus, Ixia, Oxalis, Zephy- 
ranthes, and other greenhouse bulbs. The Belladona Lily 
(Amaryllis belladona), of which flowering bulbs are annually 
imported, would, if planted near the wall, grow finely; and, 
after being established two or three years, will, every autumn, 
send up plenty of flower scapes, of a much larger size than 
those obtained from imported bulbs. This plant will also with- 
stand the severity of ordinary winters, without protection. A 
few plants of Melaleucas, Edwardsias, and Metrosideros, were, 
as far back as 1810, cultivated against a dwelling-house, in the 
nursery of Dicksons and Co., Edinburgh, where they grew for 
many years, and were, perhaps, amongst the first plants so 
treated in our island. 
200 Alstr(EMERia, treatment of. We are indebted to Mr. 
AV. Scott, the intelligent gardener at Bury Hill, for the follow- 
ing observations on the culture of Alstrcemeria, a genus of 
which he is a most successful cultivator. Most of the species 
will do very well in the open ground, but require to be planted 
under a wall, or in front of a greenhouse. As they begin to 
grow in the autumn, and early in spring, they will require 
frequent examinations, as snails and slugs are very fond of 
them ; and a covering of finely-sifted coal ashes will be found 
very useful, in keeping off these enemies, and also as a protec- 
tion from frost. The border should be made of old rotten 
manure and light loam ; and, if the subsoil be wet, a draining 
of brick rubbish would be useful, as too much moisture would
