were kept from wilting in the driest wcatlier. It was also found 

 that syringing the burlap with water increased the cooling effect, and 

 that comparatively little attention was necessary in watering.

Note way new plants develop from roots and the attempts made by the 

 plants to produce new ones. 



142. Cuttings require a moist air of proper tempera- 

 ture and sometimes bottom heat (132). This general 

 statement applies with special force to cuttings and 

 growing parts. Heat and humidity must be carefully 

 regulated to suit the species or variety of plant being 

 propagated, because the demands of each vary more or
