not stand the environment if treated as individuals. The group 
of vegetation breaks the force of the wind, and prevents the 
excessive and disastrous ten spirauion: Te is true not only of 
eciduous shrubs, of y kind. This 
was illustrated the past winter by several species here at the 
Garden which were planted both singly and in groups. 
Then there is one last resort for the protection at plants which 
one is very desirous of growin: t of doors. This is by indi- 
al protection. This requires time and care, but it will 
enable us to cultivate some eine able plants which can be 
impossible otherwise. If ittle protection is wanted, an old 
barrel placed over the a may suffice, or if this is not sufficient, 
be necessary first to wrap the plant in straw, 
ened article, before placing the barrel. Hemloc aes 
tied around a plant will often serve the purpose, and has the 
added advantage of being green and hence a pleasing object to 
view during the winter. Board fences may be built for wind- 
reak, protecting a whole collection in this way. Sometimes 
large individual trees of considerable height are protected every 
winter by placing about them a wooden portable house. This 
takes a lot of care and trouble, but if the specimen is a prized 
one, this may be the only way to do. The writer remembers a 
large tree of Araucaria imbricata, the monkey- areal which 
grew in the shelter of a dwelling in southern Connecti 
must have been twelve or fifteen feet high. ery an a fen 
wooden house was built around it, and the owner thereby had 
the satisfaction of seeing this peculiar tree in his landscape for 
a great part of the year
