144 VILLA GARDENING I'Aiit ii 



when the outside atmosi^here is mild and cahn, but keep out all 

 cold winds. In the matter of both heating and ventilating, a good 

 deal must be left to the cultivator's intelligence. Speaking gene- 

 rally, a great deal more coal and coke is burned than is necessary, 

 and the atmosphere of the conservatory might, with advantage, be 

 changed more frequently. A very small aperture in two or three 

 places will set up a circulation of air early in the morning, and 

 carry otf all impurities which have accumulated during the night. 

 I am not going to recommend any special boiler, l:)eyond saying 

 that for large places I am in favour of the improved tubidar form ; 

 biit almost any kind of boiler will do good work if properly set and 

 looked after, especially in keeping the flues clean. 



List of Plants for Conservatory. — I am speaking now 

 more especially of the permanent plants, i.e. such as are planted in 

 the borders to form the main features ; those for forcing and other 

 purposes will be referred to under their proper headings. In some 

 large gardens I know Camellias occupy a house to themselves, and 

 as they are hardy in our climate and only require protection for 

 the flowers, they are well adapted for the unheated house, which, 

 with Indian Rhododendrons, Azaleas, etc., may be made very gay. 

 Oranges, again, occasionally have a house to themselves, and in fact 

 to do them well it is desiral)le that they shovdd have a separate 

 house, though at the same time they will grow in a mixed collection. 

 The best lot of home-grown Lemons I ever saw were planted out in 

 a Muscat vinery and trained on the back wall. In the same way 

 Oranges have done well on the back walls of the Peach-house. 

 I was in a conservatory lately where a large part of the 

 back wall was covered with Orange trees traiued-in close to the 

 wall, and they were covered with fmit approaching maturity. All 

 the hybrid Abutilons are pretty, and succeed w^ell planted out in the 

 conservatory border, growing and flowering all the winter. A 

 selection of Acacias will be very suitable for a large house. I 

 name half a dozen : Grandis, longifoUa magnifica, platyptera, verti- 

 cillata, armata, and Drummondi. Araucaria Bidwilli, Ai'undo Donax 

 variegata, Bambusa viridi-glaucescens, Brugmansia suaveolens, B. 

 sanguinea, Camellias in variety, Casuarina sumatrana, Citrus in 

 variety. Cytisus racemosus is a very useful plant turned out in 

 the border. I have had it as a standard in the border, have trained 

 it on walls, arches, and pillars, and it is nearly always in flower. 

 Daphne indica, alba, and others, succeed with less trouble planted 

 out than in pots. Dracaena indivisa, Eutaxia floribunda, Ficus 

 australis, Fuchsias in great variety, Grevillea robusta, Habrotham- 

 nus fasciculatus and others, Luculia gratissima. Magnolia fuscata, 

 Musa Ensete, Myrtles, Nerium (Oleander) various, Plumbago
