 with such an immense variety to select from, coming from 

 various parts of the world, and having different periods of 

 flowering and resting, there is not much difficulty presented in its 

 attainment. 



But before this can be done it is necessary to have suitable 

 structures in which to grow and to show the plants off when in

 houses " and a series of frames, in which the plants can receive 

 suitable treatment. It is often impossible to provide the 

 necessary conditions to enable plants to complete growth or 

 to rest after flowering when grown amongst others that 

 are starting ; and in most cases plants that are at rest are
