48 ELEMENTARY FORESTRY. 
Protection to Buildings may be furnished by a few rows of 
a grove of trees. It is generally best to locate the buildings in 
a grove, or grow one up around them, so that protection may be 
afforded from every quarter to the best advantage. The garden 
should also be included in the grove or shelterbelt about the 
buildings. 
Distance ofthe Trees from the Buildings and Roadways. 
Of whatever the protection consists, it should not be close to the 
buildings or to any paths which are used in winter, for the snow 
drifts which always form to the leeward of such protection may 
become a great nuisance under such circumstances during win- 
ters of great snowlall. The windbreak had better be placed 
about one hundred feet back from the buildings, and if shade is 
wanted it can be obtained from scattered trees near the buildings, 
which will not drift the snow. The same rule applies to the 
planting of trees on the north side of a roadway. The drifts of 
snow which would®be formed to the leeward of a windbreak so 
planted would take longer to thaw in the spring, and would keep 
the road muddy and in poor condition after those that were not 
protected had become dry and firm. A row of trees is very ap- 
propriate by the side of a street or roadway and affords a pleas- 
ant shade, and if not planted too closely together will not drift 
the snow sufficiently to be an objection. 
Protection to Crops by Windbreaks. The objection to 
windbreaks close to driveways may also be made against their 
use in fields, for they often keep the land for a short distance to 
leeward wet and in unfit condition to work after the rest of the 
field has become dry. This is an objection where spring grains 
are grown, but to winter grains it is an advantage. On the 
other hand, the protection of a windbreak may give a much need- 
ed or beneficial covering of snow to crops on the leeward side. 
The protection from dust storms and drying winds has alréady 
been mentioned. The important question is how to get the ad- 
vantages without the disadvantages. In many sections the dis- 
advantage of having the snow linger on the field near the wind- 
bréak may be overcome by leaving a strip of land near it in 
permanent meadow, or use it for a rotation that does not take 
in eréps that require very early planting. But even with spring- 
planted grains it is more than probable that windbreaks properly
