It  will  be  observed  that,  although  these  grasses  were  not  ob- 
tained from  one  and  the  same  soil,  they  are  all  from  one  district, 
and  from  land  having  a somewhat  uniform  character.  The 
neighbourhood  of  Cirencester  is  in  the  oolitic  formation,  conse- 
quently the  soils  are  all  largely  mixed  with  carbonate  of  lime ; 
they  are  many  of  them  of  a “ rubbly  ” (fragmentary)  nature,  and 
for  the  most  part  self-drained.
