and August, ranging by night from 65 to 70, and by day 

 rising with the heat of the sun from 70 even to 85. 



During growth, with but few exceptions, Orchids should 

 never be exposed to the full rays of the sun ; during rest 

 the more sun and light the better. 



We cannot bring the plants to observe one rule and to 

 conform to a day or even a month ; constant watching is 

 necessary to adapt treatment to the peculiar condition of 

 each plant, and thus we see the necessity of providing 

 houses to be kept at different temperatures, that the 

 proper treatment for each plant may be afforded.
