 the pale sands. Where the forests advance 

 toward the water's edge this grass occupies 

 a narrow strip of shore between tides and 

 trees; but where the sands have drifted 

 inland, driving vegetation before them. 

 Marram Grass often covers large areas and 

 aids in arresting the encroaching desolation. 

 Although other plants are smothered by 

 wind-blown sand, this grass, continuing to 

 grow as the sand collects around it, is found 

 on high dunes with whose rise it has kept
