Many Orchids will be in a condition to need and appreciate 

 new rooting material now. Calanthes not yet potted, late flowering

 Admit air chiefly by means of the lower ventilators ; top ventila-

 lower ventilators on the lee side of the cool houses open a little 

 all night. 



Odontoglossums not in flower may be sprayed very lightly 

 overhead in the morning on all bright days.

 taken to prevent it from overgrowing seedlings, or endangering the 

 new growths of older Orchids. Clip off^ excessive sphagnum growth 

 with sharp scissors.

Ventilate early in the day, and close the houses early in the
