rectly in a Forcing-box or pots, generally made over the 

 pipes in tlie hottest house, where a temperature of 80° to 

 95° F. can be maintained. They are first soalsed in water 

 for a day or two and then liept in this heavy heat until 

 flower buds are well developed (Fig. 853). Tulips, hya-

 dangerous, and not 

 good practice; better 



(lowering wild pbiTits 

 may be forced with 

 satisfaction. 



Although no rules 

 can be given for the 

 time required in Forc- 

 ing, it is knowledge 

 not hard to acquire 

 with even surprising 

 exactness. Nothing 

 is likely to require 

 more than three

bringing in from the 

 pits. A month or six

There is great difference in plaTiis. IxlMi.liMlriuln.iis ( fhe 

 hybrids) require eight weeks or iiion-, but one species 

 will often bloom in March, within twenty-four hours. 

 Plants like the rose, which must make a growth before 

 the buds form, take more time than azaleas. The differ- 

 ence between dull and bright weather is an important 

 factor, but with extra firing, or the use of the Forcing- 

 box, these matters even up, and the average time of 

 flowering is wonderfully even. In this work, a man with 

 good plant sense is most likely to succeed.
