Cocoanuts will sproutamong rocks where thrown up by the sea, their roots sustained bythe milk while searching perhaps several yards for crevices inwhich to secure a hold and food. Countless kinds of seeds blown bywind or carried by water sprout among mountain rocks where bothsoil and water are in very small supply. Spanish moss seeds ger-minate on the limbs of trees. Mistletoe does this also, but thesprouts take parasitic root in the tissues of the tree to which theyattach themselves. Still water retards germination. In the case of buckwheat grownexperimentally, most seeds sprouted in 24 hours in running water,but those in still water took two days or FIG. 16—CUTTING FRAMEFOR WINDOWA handy device for school-rooms.

Seeds will stand much heat and coldif dry, but if wet, frost may injure them and heat maycook them. In seed storage, everything promotive ofdecay must be avoided. Especially must the seed be kept
