THE FLOWER GROWER'S GUIDE. 



in chapter devoted to Commercial Floriculture). No stagings are fixed permanently, 

 and the hot- water pipes are usually distributed, that is to say, the flow pipes are taken 

 along the sides and the "returns" brought back on each side of the central pathway. 

 All are blocked up just clear of the soil or border. During the spring, summer, and 

 autumn months, tomatoes, either in pots or planted out, are in full possession of some 

 of these houses, and cucumbers on raised mounds occupy the rest during the summer 

 months. When the time arrives for housing carnations, cyclamens, chrysanthemums, 

 cinerarias, zonale pelargoniums, and other winter flowering plants, temporary stagings 

 are erected for those kinds requiring to be raised near to the glass, while the taller 

 growing kinds, notably arums and chrysanthemums, are arranged on the borders. If 



after the tomatoes are planted will meet the case. 



Where a suitable wall exists, plain lean-to structures may be cheaply erected and 

 they are very useful. An end view of a lean-to greenhouse is shown in Fig. 64. The 

 interior arrangement, shown in the illustration, meets the requirements of a very large 

 number of persons. This class of greenhouse answers well for mixed collections of 

 plants, the staging lending itself to effective arrangement without any of the occupants 

 being unduly shaded. What is known as a "pit" in front (a) costs little, and is of 

 enormous value for preserving and growing various kinds of small or dwarf habited 

 plants. As already hinted, the particular houses under notice are not so desirable for the 

 preparation of particular kinds of conservatory plants as is a span-roofed greenhouse. 



It may be well to show a hip or three-quarter span house. This can be erected 

 against a lower wall than is necessary for a span roof. It also differs from the foregoing 

 as regards both the staging and the heating arrangements. Instead of front and back

amateurs and others adopt somewhat 

 similar arrangements, they may probably 

 derive more pleasure as well as profit 

 from their houses than they would with 

 fixed stagings. Especially is this arrange- 

 ment desirable in the case of chrysan- 

 themum enthusiasts, with a limited 

 amount of house room at their disposal. 

 Paved pathways interfere with the pre- 

 paration of the beds for tomato plants.
