Another experiment tried by Sir James Campbell himself gave
the following results:
Experiment begun in 1861 to test the value, if any, of merely
lifting and replanting oak trees in the same holes without
change of soil, situation, or giving increased space; as compared
with the experiment already detailed, which was begun in
1800.
In 1861, twelve oak trees of about 25 years' growth, which
had been self-sown (dropping from old trees afterwards cut
down) in a thick plantation, were selected, all within gunshot
of each other, and circumferences measured at five feet from
the ground. Of these, six were taken up and immediately replanted
in the same holes. The other six were not interfered with
at all.
Aggregate admeasurement of six Aggregate admeasurement of six
dug up and replanted. Marked not interfered with. Marked in
in _white_ paint 1, 2, 3, &c. _red_ paint 1, 2, 3, &c.
1861, 24-1/2 inches 27 inches (_i. e._, 2-1/2 inches more
than the transplanted ones,
at starting.
