This  experimental  work  became  a  principal  source  of  the  early  knowledge  on  which
the  properties  and  requirements  for  the  design  of  roinf orccd-concrotG  structures
was  based  by  engineers  and  engineering  organizations  and  on  T^hich  the  principles
and  methods  of  practice  were  fonaulated.   The  conception  of  relations  existing

between  the   strength  of  a  concrete  mixture  and  items   involving  the  absolute
volumes  of   cement,    sand,    and  coarse  aggregate,    and  the  voids   in  the  mixture,    as
well  as   the   so-called  relative  water  content   of  the  mixture,    put    forth  in  a  paper
in  1921,    and  in  a  later  bulletin  of   the  Engineering  Experiment    Station,    has
proved  useful   to   concrete   engineers.      Tests  of   stone,   brick,    and  concrete,    the
investigation  of   steel  columns  and  timber  stringers,    and  a  variety  of   other
experimental  and  analytical  works  lia.ve  also  aided  to   engineering  knowledge.      There
v/ere  many  contributions,    in  addition,    in  the  field  of  hydraulics.      Altogether,
Professor  Talbot   was  author  of   thirteen  bulletins,   and  was   co-author  of  nine  more.
