Shading the Trunk.

the hot plains regions, to shade the trunks of 

 young trees in order to prevent sun -scald. In the 

 nursery rows, the bodies of the trees are ordinarily 

 well shaded. There are 

 various means of provid- 

 ing this shade, but the 

 best results may be ex- 

 pected to follow from 

 some protection which 

 simply breaks the force 

 of the sun and does not 

 entirely obstruct it ; for 

 in the latter case, the 

 bark does not so read- 

 ily become inured to 

 exposure to sunshine. 

 Finely woven wire net- 

 ting rolled around the 

 tree (in more than one 

 thickness, if necessary), is 

 said to afford very good 

 protection for this pur- 

 pose, as shown in Fig. 

 43 (but preferably ex- 

 tending higher up the 

 trunk). The upper part 

 of the trunk is likely to be shaded sufficiently 

 by the branches of the tree, although this is not 

 always the case. These rolls of wire netting also 

 serve a purpose in keeping away mice and other 

 vermin.
