And here the foe of location is of prime importance. Make 
a selection protected from the sweep of the winds. Remember 
that there are few evergreens, and these among the pines, that 
orded is not sufficient it may be supplemented by planting 
the higher places with hardier and more resistant varieties, such 
as Pinus sylvestris and Pinus austriaca. This protection may 
consist of an existing wind-break of deciduous trees, as shown 
in plate CVIII. his view is in the Garden at the north end 
of the valley containing, among other collections, the economic 
garden. The native fringe of deciduous trees breaks the force 
of the winds from the north. The conifers here shown are the 
Japanese cedar, Cryptomeria japonica. There is also a small 
plant of Seguoia iM abel the Big Tree of California, 
which was set out a year ago the past fall and survived in 
excellent condition the cee trying winter. Further south 
in the same valley are trees of the Deodar, Cedrus Deodara, and 
of the Mt. Atlas Cedar, Cedrus atlantica. It would be impos- 
sible to cultivate these plants in an open wind-swept area. In 
plate CIX. an artificial wind-break is afforded by an ace 
This protects also from the north winds. The protection here is 
so effective that Chamaecyparis Lawsoniana may be cultivated, 
ifficult plant for this section, as it comes from the much milder 
and more humid climate west of the Cascade Mountains, and is 
consequently much affected by severe cold and especially by dry- 
ing winds. Its successful cultivation in this cn illustrates the 
efficiency of choice of location for individual plan

esented were severely damaged in more exposed situations in 
other parts of the Garden.
