is　to　slip　the　paper　into　his　collar…ring　and　tell　him　the　name
  of　the　person　to　take　it　to。　Naturally；　he　knows　us　all　by　name。
  So　it　is　easy　enough　for　him　to　do　it。　We　look　on　the　trick　as
  tremendously　clever。　But　that's　because　we　love　Bruce。　Almost　any
  dog　can　be　taught　to　do　it；　I　suppose。　We〃
  〃You're　mistaken！〃　corrected　the　guest。　〃Almost　any　dog　CAN'T　be
  taught　to。　Some　dogs　can；　of　course；　but　they　are　the　exception。
  I　ought　to　know；　for　I've　been　where　dog…couriers　are　a　decidedly
  important　feature　of　trench…warfare。　I　stopped　at　one　of　the　dog…
  training　schools　in　England；　too；　on　my　way　back　from　Picardy；
  and　watched　the　teaching　of　the　dogs　that　are　sent　to　France　and
  Flanders。　Not　one　in　ten　can　be　trained　to　carry　messages；　and
  not　one　in　thirty　can　be　counted　on　to　do　it　reliably。　You　ought
  to　be　proud　of　Bruce。〃
  〃We　are；〃　replied　the　Mistress。　〃He　is　one　of　the　family。　We
  think　everything　of　him。　He　was　such　a　stupid　and　awkward　puppy；
  too！　Then；　in　just　a　few　months；　he　shaped　up；　as　he　is　now。　And
  his　brain　woke。〃
  Bruce　interrupted　the　talk　by　reappearing　on　the　veranda。　The
  folded　envelope　was　still　in　the　ring　on　his　collar。　The　guest
  glanced　furtively　at　the　Master；　expecting　some　sign　of　chagrin
  at　the　collie's　failure。
  Instead；　the　Master　took　the　envelope；　unfolded　it　and　glanced　at
  a　word　or　two　that　had　been　written　beneath　his　own　scrawl；　then
  he　made　another　penciled　addition　to　the　envelope's　writing；
  stuck　the　twisted　paper　back　into　the　ring　and　said
  〃Roberts。〃
  Off　trotted　Bruce　on　his　second　trip。
  〃I　had　forgotten　to　say　which　train　you'll　have　to　take　in　the
  morning；〃　explained　the　Master。　〃So　Roberts　wrote；　asking　what
  time　he　was　to　have　the　car　at　the　door　after　breakfast。　It　was
  careless　of　me。〃
  The　guest　did　not　answer。　But　when　Bruce　presently　returned；
  this　time　with　no　paper　in　his　collar…ring；the　officer　passed
  his　hand　appraisingly　through　the　dog's　heavy　coat　and　looked
  keenly　down　into　his　dark　eyes。
  〃Gun…shy？〃　asked　the　guest。　〃Or　perhaps　he's　never　heard　a　gun
  fired？〃
  〃He's　heard　hundreds　of　guns　fired；〃　said　the　Master。　〃I　never
  allow　a　gun　to　be　fired　on　The　Place；　of　course；　because　we've
  made　it　a　bird　refuge。　But　Bruce　went　with　us　in　the　car　to　the
  testing　of　the　Lewis　machineguns；　up　at　Haskell。　They　made　a　most
  ungodly　racket。　But　somehow　it　didn't　seem　to　bother　the　Big　Dog
  at　all。〃
  〃H'm！〃　mused　the　guest；　his　professional　interest　vehemently
  roused。　〃He　would　be　worth　a　fortune　over　there。　There　are　a　lot
  of　collies　in　the　service；　in　one　capacity　or　anotheralmost　as
  many　as　the　Airedales　and　the　police　dogs。　And　they　are　doing
  grand　work。　But　I　never　saw　one　that　was　better　fitted　for　it
  than　Bruce。　It's　a　pity　he　lives　on　the　wrong　side　of　the
  Atlantic。　He　could　do　his　bit；　to　more　effect　than　the　average
  human。　There　are　hundreds　of　thousands　of　men　for　the　ranks；　but
  pitifully　few　perfect　courier…dogs。〃
  The　Mistress　was　listening　with　a　tensity　which　momentarily　grew
  more　painful。　The　Master's　forehead；　too；　was　creased　with　a　new
  thought　that　seemed　to　hurt　him。　To　break　the　brief　silence　that
  followed　the　guest's　words；　he　asked：
  〃Are　the　dogs；　over　there；　really　doing　such　great　work　as　the
  papers　say　they　are？　I　read；　the　other　day〃
  〃　'Great　work！'〃　repeated　the　guest。　〃I　should　say　so。　Not　only
  in　finding　the　wounded　and　acting　as　guards　on　listening　posts；
  and　all　that；　but　most　of　all　as　couriers。　There　are　plenty　of
  times　when　the　wireless　can't　be　used　for　sending　messages　from
  one　point　to　another；　and　where　there　is　no　telephone　connection；
  and　where　the　firing　is　too　hot　for　a　human　courier　to　get
  through。　That　is　where　is　the　war　dogs　have　proved　their　weight
  in　radium。　Collies；　mostly。　There　are　a；　million　true　stories　of
  their　prowess　told；　at　camp…fires。　Here　are　just　two　such
  incidentsboth　of　them　on　record；　by　the　way；　at　the　British　War
  Office
  〃A　collie；　down　near　Soissons；　was　sent　across　a　bad　strip　of
  fire…scourged　ground；　with　a　message。　A　boche　sharpshooter　fired
  at　him　and　shattered　his　jaw。　The　dog　kept　on；　in　horrible　agony；
  and　delivered　the　message。　Another　collie　was　sent　over　a　still
  hotter　and　much　longer　stretch　of　territory　with　a　message。　（That
  was　during　the　Somme　drive　of　1916。）　He　was　shot　at；　a　dozen
  times；　as　he　ran。　At　last　two　bullets　got　him。　He　fell　over；
  mortally　wounded。　He　scrambled　to　his　feet　and　kept　on　falling；
  stumbling；　staggeringtill　he　got　to　his　destination。　Then　he
  dropped　dead　at　the　side　of　the　Colonel　the　message　had　been　sent
  to。　And　those　are　only　two　of　thousands　of　true　collie…anecdotes。
  Yet　some　fools　are　trying　to　get　American　dogs　done　away　with；　as
  'non…utilitarian；'　while　the　war　lasts！　As　if　the　dogs　in　France；
  today；　weren't　earning　their　overseas　brothers'　right　to　live
  and　live　well！〃
  Neither　of　his　hearers　made　reply　when　the　guest　finished　his
  earnest；　eager　recital。　Neither　of　them　had　paid　much　heed　to　his
  final　words。　For　the　Master　and　the　Mistress　were　looking　at　each
  other　in　mute　unhappiness。　The　same　miserable　thought　was　in　the
  mind　of　each。　And　each　knew　the　thought　that　was　torturing　the
  mind　of　the　other。
  Presently；　at　a　glint　of　inquiry　in　the　Master's　eye；　the
  Mistress　suddenly　bent　over　and　buried　her　face　in　the　deep　mass
  of　Bruce's　ruff　as　the　dog　stood　lovingly　beside　her。　Then；　still
  stroking　the　collie's　silken　head；　she　returned　her　husband's
  wretchedly　questioning　glance　with　a　resigned　little　nod。　The
  Master　cleared　his　throat　noisily　before　he　could　speak　with　the
  calm　indifference　he　sought。　Then；　turning　to　the　apparently
  unnoticing　guest；　he　said
  〃I　think　I　told　you　I　tried　to　get　across　to　France　at　the　very
  startand　I　was　barred　because　I　am　past　forty　and　because　I
  have　a　bum　heart　and　several　other　defects　that　a　soldier　isn't
  supposed　to　have。　My　wife　and　I　have　tried　to　do　what　little　we
  can　for　the　Cause；　on　this　side　of　the　ocean。　But　it　has　seemed
  woefully　little；　when　we　remember　what　others　are　doing。　And　we
  have　no　son　we　can　send。〃
  Again　he　cleared　his　throat　and　went　on　with　sulky
  ungraciousness：
  〃We　both　know　what　you've　been　driving　at　for　the　past　five
  minutes。　Andand　we　agree。　Bruce　can　go。〃
  〃Great！〃　applauded　the　guest。　〃That's　fine！　He'll　be　worth　his〃
  〃If　you　think　we're　a　couple　of　fools　for　not　doing　this　more
  willingly；〃　went　on　the　Master　with　savage　earnestness；　〃just
  stop　to　think　what　it　means　to　a　man　to　give　up　the　dog　he　loves。
  Not　to　give　him　up　to　some　one　who　will　assure　him　a　good　home；
  but　to　send　him　over　into　that　hell；　where　a　German　bullet　or　a
  shell…fragment　or　hunger　or　disease　is　certain　to　get　him；　soon
  or　late。　To　think　of　him　lying　smashed　and　helpless；　somewhere　in
  No　Man's　Land；　waiting　for　death；　or　caught　by　the　enemy　and
  eaten！　（The　Red　Cross　bulletin　says　no　less　than　eight　thousand
  dogs　were　eaten；　in　Saxony　alone；　in　1913；　the　year　BEFORE　the
  war　began。）　Or　else　to　be　captured　and　then　cut　up　by　some　German
  vivisector…surgeon　in　the　sacred　interests　of　Science！　Oh；　we　can
  bring　ourselves　to　send　Bruce　over　there！　But　don't　expect　us　to
  do　it　with　a　good　grace。　For　we　can't。〃
  〃I〃　began　the　embarrassed　guest；　but　the　Mistress　chimed　in；
  her　sweet　voice　not　quite　steady。
  〃You　see；　Captain；　we've　made　such　a　petsuch　a　babyof　Bruce！
  All　his　life　he　has　lived　herehere　where　he　had　the　woods　to
  wander　in　and　the　lake　to　swim　in；　and　this　house　for　his　home。
  He　will　be　so　unhappy　andWell；　don't　let's　talk　about　that！
  When　I　think　of　the　people　who　give　their　sons　and　everything
  they　have；　to　the　country；　I　feel　ashamed　of　not　being　more
  willing　to　let　a　mere　dog　go。　But　then　Bruce　is　not　just　a　'mere
  dog。'　He　ishe　is　BRUCE。　All　I　ask　is　that　if　he　is　injured　and
  not　killed；　you'll　arrange　to　have　him　sent　back　here　to　us。
  We'll　pay　for　it；　of　course。　And　will　you　write　to　whomever　you
  happen　to　know；　at　that　dog…training　school　in　England；　and　ask
  that　Bruce　be　treated　nicely　while　he　is　training　there？　He's
  never　been　whipped。　He's　never　needed　it；　you　see。〃
  The　Mistress　might　have　spared　herself　much　worry　as　to　Bruce's
  treatment　in　the　training　school　to　which　he　was　consigned。　It
  was　not　a　place　of　cruelty；　but　of　development。　And　when；　out　of
  the　thousands　of　dogs　sent　there；　the　corps　of　trainers　found　one
  with　promise　of　strong　ability；　such　a　pupil　was　handled　with　all
  the　care　and　gentleness　and　skill　that　a　temperamental　prima
  donna　might　expect。
  Such　a　dog　was　the　big　American　collie；　debarked　from　a　goods　car
  at　the　training　camp　railway　station；　six　weeks　after　the
  Mistress　and　the　Master　had　consented　to　his　enlistment。　And　the
  handlers　treated　him　accordingly。
  The　Master　himself　had　taken　Bruce　to　the　transport；　in　Brooklyn；
  and　had　led　him　aboard　the　overfu
