155.  Hay. — When  grasses,  clovers  and  similar  crops
are  cut  green  and  dried  in  the  sun  they  form  what  we
call  hay.  The  havs  formed  by  coarser  grasses  such
as  corn  and  sorghum  are  called  fodder,  though  they  are
nothing  more  than  hays.  Hay  differs  from  the  original
green  fodder  in  having  lost  nearly  all  of  its  moisture.
though  apparently  perfectly  dry,  contains  on  an
ure  about  10  per  cent  of  moisture.    Of  course  there
are  many  kinds  of  hay  resulting  from  the  many  kinds
of  forage  plants,  but    we    may  divide    hays    into    two
distil  ft,    namely,   the   hay  of  grasses  and   the

hay  of  legumes.
