FOREST TREES. 223 
In its native countries the Cypress is of ines- 
timable value. Its cultivation for timber would 
doubtless succeed as far north as St. Louis, perhaps 
further. It thrives best in moist soils, or situations 
where the roots will have access to water. It endures 
the climate of Northern Illinois, but its growth is 
checked by the severity of the winters, the trees being 
sometimes split or otherwise injured by the intense 
cold. These circumstances preclude the idea of its 
successful culture as a timber tree in that latitude. Its 
light, graceful foliage and handsome appearance enti- 
tle it to notice for ornamental purposes wherever the 
climate is not too severe. It is more easily raised from 
seed than most other trees of itsclass. Michaux makes 
the following remarks in regard to its propagation: 
“The Cypress is multiplied from seed, which is the 
best method; by layers and by slips. In the begin- 
ning of spring the seeds are sown and lightly covered 
in vessels filled with mould and sand. The young 
plants must be kept in the shade and protected from 
frost. To obtain good seed, in March or April select 
the cones which begin to open, and store them in a dry 
place; the seeds which fall out are best; those which 
are obtained by opening the cones rarely germinate.” 
The Cypress should be transplanted while small, as 
the roots descend deeply into the earth wherever the 
nature of the soil permits.
