286 Gardening Under Glass 



that we may bring in and establish in gardens 

 under glass — but also a whole world of plants of 

 another character (many the result of careful and 

 long breeding or selection) which must be as 

 carefully studied as new worlds always are, in 

 order that their requirements shall be understood 

 and met. Moreover, these plants come from 

 widely different places, and require a great deal 

 more than simply protection from cold to enable 

 them to grow so far from their native clime and 

 condition; and they are not all of the same taste 

 and temperament, either — not by any means. 

 Some like much moisture and heat, others need 

 little of either, and still others come between and 

 will be satisfied with no extremes. This can be 

 easily met by a careful selection according to the 

 proposed temperature of your greenhouse ; or else 

 by having a series of "compartments" run at the 

 different temperatures to meet these varying 

 needs. Of course your own common sense tells 

 you not to expect to grow everything that may 

 be fancied in your greenhouse, simply because it 

 affords j^rotection to things that are not hardy in 

 your latitude. You will attempt growing only 

 what you make definite provision for when you 

 are building.
