The wheat plant sends up only one long green leaf which 

 corresponds to the one cotyledon. All grains grow like this, 

 such as wheat, barley, oats, and rye. The 

 leaves, sheathe each other instead of growing 

 out from the stem as the beans, peas, and mus- 

 tard seeds do. If you want to try this for your- 

 self, just plant some wheat seeds and some mus- 

 tard seeds in a wet sponge, and watch them for 

 a couple of weeks. The wheat will always send 

 up one leaf, and the mustard seed will send up 

 two. Or you can plant them on wet flannel, 

 or wet sawdust. Keep them in the dark and 

 warmth during the time they are germinating. GRAIN OF WHEAT
