GREENHOUSE 



room where the atmosphere has very little, if 

 any, moisture in it, and where the temperature 

 is away up in the nineties at one time, and 

 down dangerously near the freezing-point a 

 few hours later. Here the red spider and the 

 aphis will flourish and do their best or their 

 worst to complete the work begun by mois- 

 tureless air and a temperature which goes to 

 extremes, combined with lack of sufficient 

 light. Only when one has a place made ex- 

 pressly for plants, where all the conditions of 

 heat, moisture, and light are under control, can 

 a satisfactory measure of success in their cul- 

 ture be attained. 



The idea prevails that a greenhouse is, and 

 must be, an expensive luxury. That it is a 

 luxury we admit, but it is not an expensive 

 one, neither is it one of those luxuries which 

 come under the head of foolish extravagances 

 on which money is, to all intents and purposes, 

 thrown away. Flowers are like books and 

 pictures and music to those who love and 

 understand them. They do much in refining 

 and uplifting and developing our better 

 natures, and soon become as much necessities, 

 if we give them a chance, as the books arid 

 music cultivated people cannot well get along
