Axial Twisting — Kidney Beans July 27th 64

First show this not cause of movement—

Then give Mohl's statement of movement up, & state that K. B. round string not at all twisted, except mechanical spin which is very plain, because internode takes 3 turns round —

Also round smooth iron .35 in diameter — so round glass .25 in diameter. — But round turned smooth wood .95 in diameter, some little twisting — this I believe due to shoot not clasping well so thick a support & tip being blown off by wind— For on string & glass— the fine end became twisted & especially when it wound round & passed the transverse support at top of string & glass rod. — There was great contrast in stem round the string & glass. with those round ordinary roughish & slightly inclined sticks.— Hence it seems that twisting is connected with stem being free & in getting round odd crooked placed— Can it be to gain rigidity— like twisted rope, to support itself when quite free & revolving in climber, or in passing by odd crooked places.

The glass rod, best case, because when fixed beneath in split stick, internodes much cu twisted & at tip when it passed the supporting oblique sticks. —

Kinks on string & glass-rod, did not cause twisting, though spire made more open. —
