Shading the Trunk. 283 
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
