used good deal of California red wood
and some Colorado mountain pine, but
Texas long leafed yellow pine was the
material chiefly used. After carefully
weighing the merits of each, | came
to the conclusion before leaving there,
that the Texas pine was quite equal,
and In many resepcts preferable, to the
red wood. This pine has but little
pitch, and clisely resembles the Ore
gon red fir, which certainly has re-
markable enduring qualities, and in
my judgment is entirely reliable rot

Bear creek, three large PROSTATE logs
of red fir, apparently sound, that had
been lying SO long that trees one to
two feet in diameter had grown on top
and over them. These samples speak

slaves needs to be clear, free from sap.
