The　floor　was　of　smooth；　mosaic…fitted　blocks　of　a　faintly
  yellow　tinge。　　They　were　not　light…emitting　like　the　blocks
  that　formed　the　walls。　　The　radiance　from　these　latter；　I
  noted；　had　the　peculiar　quality　of　THICKENING　a　few　yards
  from　its　source；　and　it　was　this　that　produced　the　effect　of
  misty；　veiled　distances。　　As　we　walked；　the　seven　columns　of
  rays　streaming　down　from　the　crystalline　globes　high　above
  us　waned　steadily；　the　glow　within　the　chamber　lost　its　pris…
  matic　shimmer　and　became　an　even　grey　tone　somewhat　like
  moonlight　in　a　thin　cloud。
  Now　before　us；　out　from　the　wall；　jutted　a　low　terrace。　　It
  was　all　of　a　pearly　rose…coloured　stone；　slender；　graceful　pil…
  lars　of　the　same　hue。　　The　face　of　the　terrace　was　about　ten
  feet　high；　and　all　over　it　ran　a　bas…relief　of　what　looked　like
  short…trailing　vines；　surmounted　by　five　stalks；　on　the　tip　of
  each　of　which　was　a　flower。
  We　passed　along　the　terrace。　　It　turned　in　an　abrupt　curve。
  I　heard　a　hail；　and　there；　fifty　feet　away；　at　the　curving　end
  of　a　wall　identical　with　that　where　we　stood；　were　Larry　and
  Marakinoff。　　Obviously　the　left　side　of　the　chamber　was　a
  duplicate　of　that　we　had　explored。　　We　joined。　　In　front　of　us
  the　columned　barriers　ran　back　a　hundred　feet；　forming　an
  alcove。　　The　end　of　this　alcove　was　another　wall　of　the　same
  rose　stone；　but　upon　it　the　design　of　vines　was　much　heavier。
  We　took　a　step　forwardthere　was　a　gasp　of　awe　from
  the　Norseman；　a　guttural　exclamation　from　Marakinoff。　　For
  on；　or　rather　within；　the　wall　before　us；　a　great　oval　began　to
  glow；　waxed　almost　to　a　flame　and　then　shone　steadily　out　as
  though　from　behind　it　a　light　was　streaming　through　the
  stone　itself！
  And　within　the　roseate　oval　two　flame…tipped　shadows
  appeared；　stood　for　a　moment；　and　then　seemed　to　float　out
  upon　its　surface。　　The　shadows　wavered；　the　tips　of　flame　that
  nimbused　them　with　flickering　points　of　vermilion　pulsed
  outward；　drew　back；　darted　forth　again；　and　once　more
  withdrew　themselvesand　as　they　did　so　the　shadows　thick…
  enedand　suddenly　there　before　us　stood　two　figures！
  One　was　a　girla　girl　whose　great　eyes　were　golden　as　the
  fabled　lilies　of　Kwan…Yung　that　were　born　of　the　kiss　of　the
  sun　upon　the　amber　goddess　the　demons　of　Lao…Tz'e　carved
  for　him；　whose　softly　curved　lips　were　red　as　the　royal　coral；
  and　whose　golden…brown　hair　reached　to　her　knees！
  And　the　second　was　a　gigantic　frogA　WOMAN　frog；　head
  helmeted　with　carapace　of　shell　around　which　a　fillet　of　bril…
  liant　yellow　jewels　shone；　enormous　round　eyes　of　blue
  circled　with　a　broad　iris　of　green；　monstrous　body　of　banded
  orange　and　white　girdled　with　strand　upon　strand　of　the
  flashing　yellow　gems；　six　feet　high　if　an　inch；　and　with　one
  webbed　paw　of　its　short；　powerfully　muscled　forelegs　resting
  upon　the　white　shoulder　of　the　golden…eyed　girl！
  Moments　must　have　passed　as　we　stood　in　stark　amaze…
  ment；　gazing　at　that　incredible　apparition。　　The　two　figures；
  although　as　real　as　any　of　those　who　stood　beside　me；　un…
  phantomlike　as　it　is　possible　to　be；　had　a　distinct　suggestion
  ofprojection。
  They　were　there　before　usgolden…eyed　girl　and　gro…
  tesque　frog…womancomplete　in　every　line　and　curve；　and
  still　it　was　as　though　their　bodies　passed　back　through　dis…
  tances；　as　though；　to　try　to　express　the　wellnigh　inexpressi…
  ble；　the　two　shapes　we　were　looking　upon　were　the　end　of　an
  infinite　number　stretching　in　fine　linked　chain　far　away；　of
  which　the　eyes　saw　only　the　nearest；　while　in　the　brain　some
  faculty　higher　than　sight　recognized　and　registered　the　un…
  seen　others。
  The　gigantic　eyes　of　the　frog…woman　took　us　all　in
  unwinkingly。　　Little　glints　of　phosphorescence　shone　out
  within　the　metallic　green　of　the　outer　iris　ring。　　She　stood
  upright；　her　great　legs　bowed；　the　monstrous　slit　of　a　mouth
  slightly　open；　revealing　a　row　of　white　teeth　sharp　and
  pointed　as　lancets；　the　paw　resting　on　the　girl's　shoulder；　half
  covering　its　silken　surface；　and　from　its　five　webbed　digits
  long　yellow　claws　of　polished　horn　glistened　against　the
  delicate　texture　of　the　flesh。
  But　if　the　frog…woman　regarded　us　all；　not　so　did　the
  maiden　of　the　rosy　wall。　　Her　eyes　were　fastened　upon　Larry；
  drinking　him　in　with　extraordinary　intentness。　　She　was　tall；
  far　over　the　average　of　women；　almost　as　tall；　indeed；　as
  O'Keefe　himself；　not　more　than　twenty　years　old；　if　that；
  I　thought。　　Abruptly　she　leaned　forward；　the　golden　eyes
  softened　and　grew　tender；　the　red　lips　moved　as　though　she
  were　speaking。
  Larry　took　a　quick　step；　and　his　face　was　that　of　one　who
  after　countless　births　comes　at　last　upon　the　twin　soul　lost　to
  him　for　ages。　　The　frog…woman　turned　her　eyes　upon　the　girl；
  her　huge　lips　moved；　and　I　knew　that　she　was　talking！　　The
  girl　held　out　a　warning　hand　to　O'Keefe；　and　then　raised　it；
  resting　each　finger　upon　one　of　the　five　flowers　of　the　carved
  vine　close　beside　her。　　Once；　twice；　three　times；　she　pressed
  upon　the　flower　centres；　and　I　noted　that　her　hand　was　curi…
  ously　long　and　slender；　the　digits　like　those　wonderful　taper…
  ing　ones　the　painters　we　call　the　primitive　gave　to　their　Vir…
  gins。
  Three　times　she　pressed　the　flowers；　and　then　looked　in…
  tently　at　Larry　once　more。　　A　slow；　sweet　smile　curved　the
  crimson　lips。　　She　stretched　both　hands　out　toward　him　again
  eagerly；　a　burning　blush　rose　swiftly　over　white　breasts　and
  flowerlike　face。
  Like　the　clicking　out　of　a　cinematograph；　the　pulsing　oval
  faded　and　golden…eyed　girl　and　frog…woman　were　gone！
  And　thus　it　was　that　Lakla；　the　handmaiden　of　the　Silent
  Ones；　and　Larry　O'Keefe　first　looked　into　each　other's
  hearts！
  Larry　stood　rapt；　gazing　at　the　stone。
  〃Eilidh；〃　I　heard　him　whisper；　〃Eilidh　of　the　lips　like　the
  red；　red　rowan　and　the　golden…brown　hair！〃
  〃Clearly　of　the　Ranadae；〃　said　Marakinoff；　〃a　develop…
  ment　of　the　fossil　Labyrinthodonts：　you　saw　her　teeth；　da？〃
  〃Ranadae；　yes；〃　I　answered。　　〃But　from　the　Stegocephalia；
  of　the　order　Ecaudata〃
  Never　such　a　complete　indignation　as　was　in　O'Keefe's
  voice　as　he　interrupted。
  〃What　do　you　meanfossils　and　Stego　whatever　it　is？〃
  he　asked。　　〃She　was　a　girl；　a　wonder　girla　real　girl；　and
  Irish；　or　I'm　not　an　O'Keefe！〃
  〃We　were　talking　about　the　frog…woman；　Larry；〃　I　said；
  conciliatingly。
  His　eyes　were　wild　as　he　regarded　us。
  〃Say；〃　he　said；　〃if　you　two　had　been　in　the　Garden　of
  Eden　when　Eve　took　the　apple；　you　wouldn't　have　had　time
  to　give　her　a　look　for　counting　the　scales　on　the　snake！〃
  He　strode　swiftly　over　to　the　wall。　　We　followed。　　Larry
  paused；　stretched　his　hand　up　to　the　flowers　on　which　the
  tapering　fingers　of　the　golden…eyed　girl　had　rested。
  〃It　was　here　she　put　up　her　hand；〃　he　murmured。　　He
  pressed　caressingly　the　carved　calyxes；　once；　twice；　a　third
  time　even　as　she　hadand　silently　and　softly　the　wall　began
  to　split；　on　each　side　a　great　stone　pivoted　slowly；　and　before
  us　a　portal　stood；　opening　into　a　narrow　corridor　glowing
  with　the　same　rosy　lustre　that　had　gleamed　around　the
  flame…tipped　shadows！
  〃Have　your　gun　ready；　Olaf！〃　said　Larry。　　〃We　follow
  Golden　Eyes；〃　he　said　to　me。
  〃Follow？〃　I　echoed　stupidly。
  〃Follow！〃　he　said。　　〃She　came　to　show　us　the　way！　　Follow？
  I'd　follow　her　through　a　thousand　hells！〃
  And　with　Olaf　at　one　end；　O'Keefe　at　the　other；　both　of
  them　with　automatics　in　hand；　and　Marakinoff　and　I　be…
  tween　them；　we　stepped　over　the　threshold。
  At　our　right；　a　few　feet　away；　the　passage　ended　abruptly
  in　a　square　of　polished　stone；　from　which　came　faint　rose
  radiance。　　The　roof　of　the　place　was　less　than　two　feet　over
  O'Keefe's　head。
  A　yard　at　left　of　us　lifted　a　four…foot　high；　gently　curved
  barricade；　stretching　from　wall　to　walland　beyond　it　was
  blackness；　an　utter　and　appalling　blackness　that　seemed　to
  gather　itself　from　infinite　depths。　　The　rose…glow　in　which
  we　stood　was　cut　off　by　the　blackness　as　though　it　had　sub…
  stance；　it　shimmered　out　to　meet　it；　and　was　checked　as
  though　by　a　blow；　indeed；　so　strong　was　the　suggestion　of
  sinister；　straining　force　within　the　rayless　opacity　that　I
  shrank　back；　and　Marakinoff　with　me。　　Not　so　O'Keefe。　　Olaf
  beside　him；　he　strode　to　the　wall　and　peered　over。　　He　beck…
  oned　us。
  〃Flash　your　pocket…light　down　there；〃　be　said　to　me；　point…
  ing　into　the　thick　darkness　below　us。　　The　little　electric　circle
  quivered　down　as　though　afraid；　and　came　to　rest　upon　a
  surface　that　resembled　nothing　so　much　as　clear；　black　ice。　　I
  ran　the　light　acrosshere　and　there。　　The　floor　of　the　corridor
  was　of　a　substance　so　smooth；　so　polished；　that　no　man　could
  have　walked　upon　it；　it　sloped　downward　at　a　slowly　increas…
  ing　angle。
