  He's　deaf　as　a　post；　too；　from　shell…shock。　He　tumbled　over　in　a

  But　the　surgeon…general　waded　in　and　took　a　hand　in　the　game

  〃I　didn't　mean　to　be　fresh；〃　apologized　the　jaunty　one。　〃Won't

  The　boche　heavies　and　snipers　and　machine…guns　all　cut　loose　to
  stop　him　as　he　scooted　up　the　hill。　And　a　measly　giant　of　a
  German　police　dog　tried　to　kill　him；　too。　Bruce　got　through　the
  lot　of　them；　and　he　reached　headquarters　with　the　SOS　call　that
  saved　us。　The　poor　chap　was　cut　and　gouged　and　torn　by　bullets
  and　shell…scraps；　and　he　was　nearly　dead　from　shell…shock；　too。
  But　the　surgeon　general　worked　over　him；　himself；　and　pulled　him

  〃He　is　a　loved　pet　of　a　man　and　a　woman　in　your　America；　I　have

  welcome。〃
  When　Bruce；　an　hour　later；　trotted　into　the　trenches；　on　the　way
  to　the　〃Here…We…Come〃　colonel's　quarters；　he　was　received　like　a
  visiting　potentate。　Dozens　of　men　hailed　him　eagerly　by　name　as
  he　made　his　way　to　his　destination　with　the　message　affixed　to
  his　collar。
  Many　of　these　men　were　his　well…remembered　friends　and　comrades。
  Mahan　and　Vivier；　and　one　or　two　more；　he　had　grown　to　likeas
  well　as　he　could　like　any　one　in　that　land　of　horrors；　three
  thousand　miles　away　from　The　Place；　where　he　was　born；　and　from
  the　Mistress　and　the　Master；　who　were　his　loyally　worshiped　gods。
  Moreover；　being　only　mortal　and　afflicted　with　a　hearty　appetite；
  Bruce　loved　the　food　and　other　delicacies　the　men　were　forever
  offering　him　as　a　variation　on　the　stodgy　fare　dished　out　to　him
  and　his　fellow　war…dogs。
  As　much　to　amuse　and　interest　the　soldiers　whose　hero　he　was；　as
  for　any　special　importance　in　the　dispatch　he　carried；　Bruce　had
  been　sent　now　to　the　trenches　of　the　Here…We…Comes。　It　was　his
  first　visit　to　the　regiment　he　had　saved；　since　the　days　of　the
  Rache　assault　two　months　earlier。　Thanks　to　supremely　clever
  surgery　and　to　tender　care；　the　dog　was　little　the　worse　for　his
  wounds。　His　hearing　gradually　had　come　back。　In　one　shoulder　he
  had　a　very　slight　stiffness　which　was　not　a　limp；　and　a
  new…healed　furrow　scarred　the　left　side　of　his　tawny　coat。
  Otherwise　he　was　as　good　as　new。
  As　Bruce　trotted　toward　the　group　that　so　recently　had　been
  talking　of　him；　the　Missouri　recruit　watched　with　interest　for
  the　dog's　joy　at　this　reunion　with　his　old　friends。　Bruce's　snowy
  chest　and　black…stippled　coat　were　fluffed　out　by　many　recent
  baths。　His　splendid　head　high　and　his　dark　eyes　bright；　the
  collie　advanced　toward　the　group。
  Mahan　greeted　him　joyously。　Vivier　stretched　out　a　hand　which
  displayed　temptingly　the　long…hoarded　lump　of　sugar。　A　third　man
  produced；　from　nowhere　in　particular；　a　large　and　meat…fringed
  soup…bone。
  〃I　wonder　which　of　you　he'll　come　to；　first；〃　said　the　interested
  Missourian。
  The　question　was　answered　at　once；　and　right　humiliatingly。　For
  Bruce　did　not　falter　in　his　swinging　stride　as　he　came　abreast　of
  the　group。　Not　by　so　much　as　a　second　glance　did　he　notice
  Mahan's　hail　and　the　tempting　food。
  As　he　passed　within　six　inches　of　the　lump　of　sugar　which　Vivier
  was　holding　out　to　him；　the　dog's　silken　ears　quivered　slightly；
  sure　sign　of　hard…repressed　emotion　in　a　thoroughbred　collie；
  but　he　gave　no　other　manifestation　that　he　knew　any　one　was
  there。
  〃Well；　I'll　be　blessed！〃　snickered　the　Missourian　in　high
