Ever since Mr. Darwin's little work, the motion of tendrils has become an interesting study. In Scientific Farmer for March, Prof. Penhallow gives some account of observations made on a squash. The tendrils soon after development commence motion - searching for something to cling to. The revolutions continue for two or three days, at no regular rate, when, if no support is found the tendrils die there. Often about the fourth day they will fall to the ground exhausted, and, after a few hours start up again, make a few more revolutions and fall back again. It will often do this several times before giving up finally. How much these act like animated things!
