Shoot nearly yard long —no leaves, depended

~~At least 20 inches~~ Nearly two feet of of this ci curled from side to like a snake with tip I I believe going round — movement slow.

I think nearly whole yard moves.

Nov. 23d I may say that the swaying & curling movement of whole shoot & rotation of axis is slow & irregular from about 16° to 22° or 24°.— Observation made during several days. — Horwood says that little roots or shoots stick like Ivy!!!

(Certainly tip curls but not very well round any object.)

(Shoot 32 inches long — 6 internodes & 1 shoot one inch long.—)
