L quote from bulletin No. 700 OF the Iowa

OF Oregon fir:
Oregon flr IS an excellent wood for stave
silos, as IT can be secured In full-Icneth
slaves and Is quite clear and uniform With
reasonable care and foundation high
enough 10 raise II above moisture a siIo with
FIR slaves should last for a long term OF
years"
From The Same bulletin quote references
made 10 other materials used in sno con-
struction which may be of interest:
Redwood is one OF the confcrs which IL
generally accepted as having the best last
ing qualities OF any wood used In silo con-
struction. Redwood trees are very large and
the lumber uniform. In buying redwood
silos a very good grade OF practically clear
and full-length slaves may be secured The
shrinkagc and swelling due TO moisture Is
less than In other woods This is quite an
advantage on account OF tho shrinknge that
