GLAUCOUS-LEAVED MAGNOLIA. 9 
Propagation and Culture. Plants of this species are generally produced 
from seeds ; but the Magnolia glauca thompsoniana, and other varieties, are pro- 
pagated by inarching, or by layers, which require two years to root properly. 
The seeds should be sown in pots of bog earth about the beginning of March, 
or later, according to the climate or season, and placed in gentle heat, if neces- 
sary, under glass. They should annually be transplanted into small pots until 
they are wanted for final planting. A tree in ordinary circumstances will 
attain the height of one foot per annum until it is fifteen or twenty feet high, 
after which it will remain stationary. 
Insects. The Magnolia glauca is very free from the attack of insects. It is 
noted, however, in Smith and Abbot's " Insects of Georgia," that the Sphinx vitis 
feeds upon this tree as well as upon the grape-vine. 
Properties and Uses. In general, this tree can only be used for ornamental 
purposes, and no collection should be without it. The wood, however, is some- 
times employed for making joiners' tools ; and the bark is also used in some 
parts of the country, like that of the cinchona, in the case of intermittent and 
remittent fevers. It is aromatic and pungent, apparently more so than the other 
species. When distilled, it has a peculiar flavour, and an empyreumatic smell. 
In a dry state it affords a little resin. The aroma is volatile, and probably con- 
tains an essential oil, or a variety of camphor. The bark, seeds, and cones, are 
employed in tincture, in chronic rheumatism. That from the cones is very bitter, 
and is sometimes used to cure coughs and pectoral diseases, and for preventing 
autumnal fevers. The flowers in a dried state, may be used in drawing-rooms 
for pot pourri, as a substitute for those of the lily of the valley.
