GUTTING ESTABLISHED

Some seeds bury themselves. The Filaree, Foxtail 

 and Wild Oats have seeds of this kind. If you can 

 obtain these, place them on the sur- 

 face of moist soil (a rough, uneven 

 surface is best) , and water them oc- 

 casionally. How do the "clocks" 

 assist in burying the Filaree? In 

 order to see them work to best ad- 

 vantage, they should be placed (seed 

 end down) on moist cotton (see 

 Fig. 55). The seeds of the garden 

 Geranium (or Pelargonium) act in 

 the same way, but to a very slight 

 degree as compared with the Filaree. 



Buried seeds, 

 which escape 

 from their coverings only to find 

 themselves imprisoned under ground, 

 have before them the problem of get- 

 ting their stems up into the air and 

 light ; which plants seem to achieve this 

 most easily? Notice the Corn (Fig. 

 56), which seems to pierce the soil 

 with ease by means of its sharp bod- 

 kin of fii'mly rolled leaves; the Scar- 

 let Runner (Fig. 57) seems clumsy by 

 comparison, ramming its crooked
