Quereus virens, L.* 
The Live Oak of North America, evergreen, 60 feet high. Supplies a 
most valuable timber for shipbuilding; it is heavy, compact, fine¬ 
grained ; it is moreover the strongest and most durable of all American 
Oaks. Like <?. obtusiloba, Miohaux., it lives also on seashores, helping 
to bind the sand, but it is then not of tali stature. Of many of the 600 
Oaks of both the Western and Eastern portion of the Northern hemis¬ 
phere, the properties remained unrecorded and perhaps uuexatnined* 
but it would he important to introduce as many kinds as possible for 
local test-growth. The acorns, tvheu packed in dry moss, retain 
their vitality for some mouths. The species with deciduous foliage are 
not desirable for massive ornamental planting, because in this clime 
they shed their dead leaves tardily daring the very time of our greatest 
verdure.
