orchids: how to okow in km successfully. .39 



be borne in Tiiind that some of these climbers are subject to mealy 

 bug and other troublesome inst^cts which ^\'ill ne(!d careful watching 

 and attention. 



THE COOL HOUSE. 



Fig. D. and E. represents a model house, should a new structure 

 l)e (a-ected for Cool house Orchids, and it should have east and 

 west side aspects, so as to get an equal amount of light. A. shows 

 the bottom ventilation, which should be on a level with the 

 hot- water pipes and protected inside with perforated zinc, with 

 the holes not too small, but sufficiently so to keep out vermin. 

 />. shows top ventilation, and ('. shows sid(^ ventilation, which is 

 veiy beneficial to Cool Orcliids, if opened slightly when the 

 atmosphere outside is damp and not veiy cold, but they should 

 not be open in very dry or cold weather. J), shows the framework 

 to suppoi-t the roller blinds, and E. the roller blind. /'. is the end 

 s(»ction, showing the centre and side stages, which should be open 

 wood-work, so that the air may have free circulation amongst the 

 plants. a. indicates the slates or tiles supported on bricks, 

 immediately over and three or four inches from the pipes, and on 

 these half decapng leaves of trees should be placed at intervals, to 

 throw off a nice moisture; impregnated with amiuonia from the 

 leaves, and assimilated with the dry heat from the pipes. H. is 

 the soft watt'r tank, a great essential in an Orchid-house. If a 

 supply from an outside pressure from waterworks in the town 

 .should exist, and an india rubber hose sufficiently long is connected, 

 the entire length of the house can soon be damped down — and this 

 is so often nt^edcd in hot, dry weather — thoroughly watering every 

 available space about the floor and stages, without watering the 

 plants over head. If a syiinge has to be used for this pm-^DOse, 

 much longer time is required. 



THE INTERMEDIATE HOUSE. 



Such a house running from east to west, the sides having one 

 H northern, the other a southern aspect, would enable an amateui* 

 to gi-ow a still greater variety of Orchids successfully — those 

 requiring a great amoimt of light being placed on the south side, 

 and those loving shade on the northern side. Tliis house is 

 identical in structure with the Cool house, with this exception.
