〃But　a　billion　dollars　is　inconceivable；〃　retorted　the　boy。　　〃No　mind
  can　take　in　a　sum　of　that　size；　but　it　exists。〃
  〃Put　that　down！　put　that　down！〃　shrieked　the　other　boy。　　〃You've　struck
  something。　　If　we　get　Berkeley　on　the　paper；　I'll　run　that　in。〃　　He
  wrote　rapidly；　and　then　took　a　turn　around　the　room；　frowning　as　he
  walked。　　〃The　actuality　of　a　thing；〃　said　he；　summing　his　clever
  thoughts　up；　〃is　not　disproved　by　its　being　inconceivable。　　Ideas　alone
  depend　upon　thought　for　their　existence。　　There！　　Anybody　can　get　off
  stuff　like　that　by　the　yard。〃　　He　picked　up　a　cork　and　a　foot…rule；
  tossed　the　cork；　and　sent　it　flying　out　of　the　window　with　the
  foot…rule。
  〃Skip　Berkeley；〃　said　the　other　boy。
  〃How　much　more　is　there？〃
  〃Necessary　and　accidental　truths；〃　answered　the　tutor；　reading　the
  subjects　from　his　notes。　　〃Hume　and　the　causal　law。　　The　duality；　or
  multiplicity；　of　the　ego。〃
  〃The　hard…boiled　ego；〃　commented　the　boy　the　ruler；　and　he　batted　a
  swooping　June…bug　into　space。
  〃Sit　down；　idiot；〃　said　his　sprightly　mate。〃
  Conversation　ceased。　　Instruction　went　forward。　　Their　pencils　worked。
  The　causal　law；　etc。；　went　into　their　condensed　notes　like　Liebig's
  extract　of　beef；　and　drops　of　perspiration　continued　to　trickle　from
  their　matted　hair。
  II
  

  Bertie　and　Billy　were　sophomores。　　They　had　been　alive　for　twenty　years；
  and　were　young。　　Their　tutor　was　also　a　sophomore。　　He　too　had　been
  alive　for　twenty　years；　but　never　yet　had　become　young。　　Bertie　and
  Billy　had　colonial　names　（Rogers；　I　think；　and　Schuyler）；　but　the
  tutor's　name　was　Oscar　Maironi；　and　he　was　charging　his　pupils　five
  dollars　an　hour　each　for　his　instruction。　　Do　not　think　this　excessive。
  Oscar　could　have　tutored　a　whole　class　of　irresponsibles；　and　by　that
  arrangement　have　earned　probably　more；　but　Bertie　and　Billy　had
  preempted　him　on　account　of　his　fame　or　high　standing　and　accuracy；　and
  they　could　well　afford　it。　　All　three　sophomores　alike　had　happened　to
  choose　Philosophy　4　as　one　of　their　elective　courses；　and　all　alike　were
  now　face　to　face　with　the　Day　of　Judgment。　　The　final　examinations　had
  begun。　　Oscar　could　lay　his　hand　upon　his　studious　heart　and　await　the
  Day　of　Judgment　likeI　had　nearly　said　a　Christian！　　His　notes　were
  full：　Three　hundred　pages　about　Zeno　and　Parmenides　and　the　rest；　almost
  every　word　as　it　had　come　from　the　professor's　lips。　　And　his　memory　was
  full；　too；　flowing　like　a　player's　lines。　　With　the　right　cue　he　could
  recite　instantly：　〃An　important　application　of　this　principle；　with
  obvious　reference　to　Heracleitos；　occurs　in　Aristotle；　who　says〃　He
  could　do　this　with　the　notes　anywhere。　　I　am　sure　you　appreciate　Oscar
  and　his　great　power　of　acquiring　facts。　　So　he　was　ready；　like　the　wise
  virgins　of　parable。　Bertie　and　Billy　did　not　put　one　in　mind　of　virgins：
  although　they　had　burned　considerable　midnight　oil；　it　had　not　been　to
  throw　light　upon　Philosophy　4。　　In　them　the　mere　word　Heracleitos　had
  raised　a　chill　no　later　than　yesterday；the　chill　of　the　unknown。　　They
  had　not　attended　the　lectures　on　the　〃Greek　bucks。〃　　Indeed；　profiting
  by　their　privilege　of　voluntary　recitations；　they　had　dropped　in　but
  seldom　on　Philosophy　4。　　These　blithe　grasshoppers　had　danced　and　sung
  away　the　precious　storing　season；　and　now　that　the　bleak　hour　of
  examinations　was　upon　them；　their　waked…up　hearts　had　felt　aghast　at　the
  sudden　vision　of　their　ignorance。　　It　was　on　a　Monday　noon　that　this
  feeling　came　fully　upon　them；　as　they　read　over　the　names　of　the
  philosophers。　　Thursday　was　the　day　of　the　examination。　　〃Who's
  Anaxagoras？〃　　Billy　had　inquired　of　Bertie。　　〃I'll　tell　you；〃　said
  Bertie；　〃if　you'll　tell　me　who　Epicharmos　of　Kos　was。〃　　And　upon　this
  they　embraced　with　helpless　laughter。　　Then　they　reckoned　up　the　hours
  left　for　them　to　learn　Epicharmos　of　Kos　in；between　Monday　noon　and
  Thursday　morning　at　nine；and　their　quailing　chill　increased。　　A　tutor
  must　be　called　in　at　once。　　So　the　grasshoppers；　having　money；　sought
  out　and　quickly　purchased　the　ant。
  Closeted　with　Oscar　and　his　notes；　they　had；　as　Bertie　put　it；　salted
  down　the　early　Greek　bucks　by　seven　on　Monday　evening。　　By　the　same
  midnight　they　had；　as　Billy　expressed　it；　called　the　turn　on　Plato。
  Tuesday　was　a　second　day　of　concentrated　swallowing。　　Oscar　had　taken
  them　through　the　thought　of　many　centuries。　　There　had　been
  intermissions　for　lunch　and　dinner　only；　and　the　weather　was　exceedingly
  hot。　　The　pale…skinned　Oscar　stood　this　strain　better　than　the
  unaccustomed　Bertie　and　Billy。　　Their　jovial　eyes　had　grown　hollow
  to…night；　although　their　minds　were　going　gallantly；　as　you　have
  probably　noticed。　　Their　criticisms；　slangy　and　abrupt；　struck　the
  scholastic　Oscar　as　flippancies　which　he　must　indulge；　since　the　pay　was
  handsome。　　That　these　idlers　should　jump　in　with　doubts　and　questions
  not　contained　in　his　sacred　notes　raised　in　him　feelings　betrayed　just
  once　in　that　remark　about　〃orriginal　rresearch。〃
  〃Nineteneleventwelve；〃　went　the　little　timepiece；　and　Oscar　rose。
  〃Gentlemen；〃　he　said；　closing　the　sacred　notes；　〃we　have　finished　the
  causal　law。〃
  〃That's　the　whole　business　except　the　ego　racket；　isn't　it？〃　said　Billy。
  〃The　duality；　or　multiplicity　of　the　ego　remains；〃　Oscar　replied。
  〃Oh；　I　know　its　name。　　It　ought　to　be　a　soft　snap　after　what　we've　had。〃
  〃Unless　it's　full　of　dates　and　names　you've　got　to　know；〃　said　Bertie。
  〃Don't　believe　it　is；〃　Billy　answered。　　〃I　heard　him　at　it　once。〃　（This
  meant　that　Billy　had　gone　to　a　lecture　lately。）　〃It's　all　about　Who　am
  I？　and　How　do　I　do　it？〃　　Billy　added。
  〃Hm！〃　said　Bertie。　　〃Hm！　　Subjective　and　objective　again；　I　suppose；
  only　applied　to　oneself。　　You　see；　that　table　is　objective。　　I　can　stand
  off　and　judge　it。　　It's　outside　of　me；　has　nothing　to　do　with　me。　That's
  easy。　　But　my　opinion　ofwell；　mywell；　anything　in　my　nature〃
  〃Anger　when　it's　time　to　get　up；〃　suggested　Billy。
  〃An　excellent　illustration；〃　said　Bertie。　　〃That　is　subjective　in　me。
  Similar　to　your　dislike　of　water　as　a　beverage。　　That　is　subjective　in
  you。　　But　here　comes　the　twist。　　I　can　think　of　my　own　anger　and　judge
  it；　just　as　if　it　were　an　outside　thing；　like　a　table。　　I　can　compare　it
  with　itself　on　different　mornings　or　with　other　people's　anger。　　And　I
  trust　that　you　can　do　the　same　with　your　thirst。〃
  〃Yes；〃　said　Billy；　〃I　recognize　that　it　is　greater　at　times　and　less　at
  others。〃
  〃Very　well；　There　you　are。　　Duality　of　the　ego。〃
  〃Subject　and　object；〃　said　Billy。　　〃Perfectly　true；　and　very　queer　when
  you　try　to　think　of　it。　　Wonder　how　far　it　goes？　　Of　course；　one　can
  explain　the　body's　being　an　object　to　the　brain　inside　it。　　That's　mind
  and　matter　over　again。　　But　when　my　own　mind　and　thought；　can　become
  objects　to　themselvesI　wonder　how　far　that　does　go？〃　he　broke　off
  musingly。　　〃What　useless　stuff！〃　he　ended。
  〃Gentlemen；〃　said　Oscar；　who　had　been　listening　to　them　with　patient；
  Oriental　diversion；　〃I〃
  〃Oh；〃　said　Bertie；　remembering　him。　　〃Look　here。　　We　mustn't　keep　you
  up。　We're　awfully　obliged　for　the　way　you　are　putting　us　on　to　this。
  You're　saving　our　lives。　　Ten　to…morrow　for　a　grand　review　of　the　whole
  course。〃
  〃And　the　multiplicity　of　the　ego？〃　inquired　Oscar。
  〃Oh；　I　forgot。　　Well；　it's　too　late　tonight。　　Is　it　much？　　Are　there
  many　dates　and　names　and　things？〃
  〃It　is　more　of　a　general　inquiry　and　analysis；〃　replied　Oscar。　　〃But　it
  is　forty　pages　of　my　notes。〃　　And　he　smiled。
  〃Well；　look　here。　　It　would　be　nice　to　have　to…morrow　clear　for
  review。　　We're　not　tired。　　You　leave　us　your　notes　and　go　to　bed。〃
  Oscar's　hand　almost　moved　to　cover　and　hold　his　precious　property；　for
  this　instinct　was　the　deepest　in　him。　　But　it　did　not　so　move；　because
  his　intelligence　controlled　his　instinct　nearly；　though　not　quite；
  always。　　His　shiny　little　eyes；　however；　became　furtive　and
  antagonisticsomething　the　boys　did　not　at　first　make　out。
  Oscar　gave　himself　a　moment　of　silence。　　〃I　could　not　brreak　my　rule；〃
  said　he　then。　　〃I　do　not　ever　leave　my　notes　with　anybody。　　Mr。
  Woodridge　asked　for　my　History　3　notes；　and　Mr。　Bailey　wanted　my　notes
  for　Fine　Arts　1；　and　I　could　not　let　them　have　them。　　If　Mr。　Woodridge
  was　to　hear〃
  〃But　what　in　the　dickens　are　you　afraid　of？〃
  〃Well；　gentlemen；　I　would　rather　not。　　You　would　take　good　care；　I　know；
  but　there　are　sometimes　things　which　happen　that　we　cannot　help。　One
  time　a　fire〃
  At　this　racial　suggestion　both　boys　made　the　room　joyous　with　mirth。
  Oscar　stood　uneasily　contemplating　them。　　He　would　never　be　able　to
  understand　them；　not　as　long　as　he　lived；　nor　they　him。　　When　their
  mirth　Was　over　he　did　somewhat　better；　but　it　was　tardy。　　You　see；　he
  was　not　a　specimen　of　the　first　rank；　or　he　would　have　said　at　once　what
  he　said　now：　〃I　wish　to　s
