evaporated  milk  for  home  consumption.  While  but  12,000  pounds 
were  tinned  in  1916,  more  than  62,000,000  pounds  of  the  case  goods 
were  manufactured  in  191 9,  as  shown  by  the  following  table.  In 
19 1 6,  the  production  of  the  substitute  compared  with  the  produc- 
tion of  true  evaporated  milk,  case  goods,  was  negligible,  while  the 
production  had  increased  to  over  5  per  cent,  by  the  close  of  1919:

Dr.  D.  R.  Mendenhall  states  that  "from  the  feeding  experiments 
recently  conducted  on  animals  it  does  not  seem  probable  that  either 
of  the  vitamines  so  far  determined  is  injured  by  the  high  tempera- 
ture. By  diluting  with  equal  parts  of  sterile  water,  evaporated  milk 
can  be  reconstituted,  approximately,  as  ordinary  milk;  also,  it  can 
be  of  great  use  in  the  general  nutrition  of  the  household  and  it  cer- 
tainly has  a  more  tenable  place  in  the  feeding  of  infants  and  young 
children,  when  fresh  milk  cannot  be  obtained,  than  condensed  milk. 
We  must  recognize  the  facts  that  it  will  freeze  and  is,  therefore, 
not  suitable  for  transportation  in  cold  weather;  that  it  must  be  care- 
fully handled  after  opening  the  can,  if  it  is  to  remain  a  sterile  food 
and  one  fit  to  give  an  infant;  and  that  even  though  condensed  to 
one-half  to  two-fifths  of  its  original  bulk,  it  is  still  bulky  to  trans- 
port. Also,  all  condensed  milk  is  relatively  high  in  price  as  com- 
pared with  grade  A,  raw  milk  *  *  *  *  these  reasons 
make  evaporated  milk  far  from  the  ideal  substitute  for  fresh  milk."
