 worth being ill to enjoy such a scene." 



Encoui-agement like this must surely add new life and

 be induced to try their skill. The great secret is robust growth 

 in summer, when there is plenty of heat in the greenhouses ; 

 but for further and particular instruction, see the chapter on 

 the cultivation of the In/caste, and also that on the treatment

 and where only a few plants exist, such a plan is by no means
