“  We  commend  tkis  book  as  a  clear,  elaborate,  and  practieal  treatise  upon
the  department  of  iron  manufacturing  operations  to  which  it  is  devoted.
The  -«riter  states  in  his  preface,  that  for  twenty-five  years  he  has  feit  the
necessity  of  such  a  work,  and  has  evidently  brought  to  its  preparation  the
fruits  of  experience,  a  painstaking  regard  for  accuracy  of  statement,  and  a
desire  to  furnish  Information  in  a  style  readily  understood.  The  book  should
be  in  the  hands  of  every  one  interested,  either  in  the  general  praetice  of
mechanieal  engineering,  or  the  special  branch  of  manufacturing  operations  to
-which  the  work  relates.’’—American  Artisan.
