THE ORCHID WORLD. 



in growing it, his method of culture may be of 

 some considerable help to others less fortunate. 



He ascribes his success in a great measure to 

 giving abundance of air when the outside 

 conditions will permit. He endeavours to 

 secure a minimum day temperature during the 

 growing months of 70 deg. F., and this with 

 top and bottom ventilation. The house is 

 provided with side lights which open besides 



sufficient water is given to prevent shrivelling, 

 and a buoyant, intermediate temperature of 

 4S to 50 degrees is maintained. The plants 

 are potted in Osmunda fibre, moss, and 

 crocks. 



Suspended from the rafters in this house 

 were many strong plants of Epidendrum 

 vitellinum in fine productive growth. 



The seedling house is 33 feet by 12 feet,

the usual bottom ventilators over the pipes, 

 and all are opened to their full capacity on 

 suitable days. A considerable amount of top 

 ventilation is left on the house at night during 

 the summer. The plants are watered in the 

 afternoon, and when in active growth are 

 frequently syringed, and at this period 

 occasionally with soot water, which must be of 

 immense benefit to plants with so many aerial 

 roots. During winter, when the roots seal 

 over and growth is reduced to a minimum, just 



and has a heated case built on one staging to 

 slope with the glass. The bottom of the case 

 is made of perforated zinc, over which sphag- 

 num moss is placed, and in this the seed pans 

 are plunged to half their depth. One relies 

 largely on brisk, moist heat for raising the 

 Cattleya and Laelia seed, and this was ger- 

 minating and growing with great freedom, and 

 evidence of recent success was to be seen in 

 the many thousands of seedlings that were 

 distributed over the various houses, only a
