9th and 10th day same Position — llth day lateral branches un- 
folding, and on to 14 tb day remained in same position with 
branches nnfolded when observations ended. 
8) Shoot 6.5 cm tall when covered, erect; older slioots outside 
cover, 9 cm tall when transverse bend was made. After 2 days, 
covered shoot bent 45° from vertical — after 3 days more declined 
to70° —1 day more same — during following 14 days declined to 
90° and nnfolded lateral branches. Numerous observations showed 
no considerable nutation of tip from time declination began. Total 
length of shoot 20 cm. Period of Observation 26 days. 
9) Shoot 7.7 cm tall when convered, erect; older shoots 
outside cover were 14 cm tall when transverse bend was made. 
After 2 days covered shoot declined to 80° — so continued for 
10 days when lateral branches of first Order were nnfolded. Total 
hight of shoot 18 cm. Period of Observation 12 days. 
The examples described under 6, 7, 8 and 9 above are clear 
cases of cessation of growth after the upper part of the shoots 
had reached the transverse position. The following 4 plants had 
perhaps not reached their definitive position, for they had not un- 
folded their lateral branches when the experiments were ended. 
These 4 shoots however declined steadily each in one plane, instead 
of nutating irregularly as did numbers 1, 2, 3, 4 and 5, indicating 
that light had some inflnence. 
10) Shoot 1.7 cm above ground when covered, vertical; older 
shoots outside cover were 20 cm tall when transverse bend was 
made. After 8 days covered shoot declined to 40 0 — so continued 
for 12 days, when shoot 36 cm long — during next 8 days shoot 
declined to 90° where it remained for 6 days when experiment 
ended. Lateral branches were not unfolded. Period of Observation 
34 days. 
11) Shoot 4.5 cm tall when convered — for 11 days mostly 
vertical, then declined 30° — 12 th day same — 13 th day same — 
14 th day declined to 45° when experiment ended. 
12) Shoot 3.5 cm tall when covered — for 9 days vertical, 
then declined 30° — llth day declined to35° — 12th day same 
— 13 th day declined to 45° — 14 th day same when experiment 
ended. 
13) Shoot 1.5 cm tall when covered — vertical tili llth 
day when tip declined 15° — 12 th day same — 13 th day vertical 
— 13 th day evening declined to 30° — 14 th day declined to 40°, 
and experiment ended. 
The following 4 shoots were continued long enough under 
experiment to determine whether the plagiogeotropic position which 
they took was final. The effect of light is still evident: 
14) Shoot 28 mm above ground when covered, grew erect 
for 10 days, when it reached hight of 24 cm. Older shoots outside 
cover showed length of 21 cm, the diageotropic curve being 11 cm 
above ground. On llth day, covered shoot declined 15° — so 
continued for 3 days, then declined to 20° — next day declined 
to 30° — 17 th day vertical tip, leaving section below bent 30° —
