THE NURSERY-MANUAL 



In commercial establishments, cuttings are grown exten- 

 sively in summer. The cuttings are made of growing or matur- 

 ing shoots taken from 

 the natural outdoor 

 growth, as cuttings 

 of similar maturity 

 may be taken from 

 greenhouse stuff in 

 winter and spring. 

 Cover and protection 

 must be provided 

 for these summer 

 cuttings. Low glass- 

 houses, of the forc-

used, being well 



shaded. Such houses are indicated in Fig. 86. They may be 

 utilized for seed-propagation or other work, if needed. Frames 

 are useful, as in Fig. 87; and these are also usable in spring 

 for receiving surplus 

 stock from the 

 greenhouse. They 

 are commonly pro- 

 vided with slat- 

 covers, as shown, to 

 go over the glass; 

 or in summer the 

 covers alone may be 

 used. Usually the 

 frames are ranged 

 together in a yard, 

 and high shading is provided by means of muslin as illus- 

 trated in Fig. 9 and again in Fig. 88.
