Moreover，thesedust—raisingdialecticiansignoresomeofthemostimportantandwell—knownfactswhichbearuponthequestion。AnythingmorethanaparochialacquaintancewithphysicalgeographyandgeologywouldsufficetoreminditspossessorthattheHolyLanditselfoffersastandingprotestagainstbringingsuchadelugeasthatofNoahanywherenearit，eitherinhistoricaltimesorinthecourseofthatpleistoceneperiod，ofwhichthe\"greaticeage\"formedapart。
JudaeaandGalilee，MoabandGilead，occupypartofthatextensivetablelandatthesummitofthewesternboundaryoftheEuphratesvalley，towhichIhavealreadyreferred。Ifthatvalleyhadeverbeenfilledwithwatertoaheightsufficient，notindeedtocoverathirdofArarat，inthenorth，orhalfofsomeofthemountainsofthePersianfrontierintheeast，buttoreachevenfourorfivethousandfeet，itmusthavestoodoverthePalestinianhog’sback，andhavefilled，uptothebrim，everydepressiononitssurface。ThereforeitcouldnothavefailedtofillthatremarkabletrenchinwhichtheDeadSea，theJordan，andtheSeaofGalileelie，andwhichisknownasthe\"Jordan—Arabah\"valley。
Thislonganddeephollowextendsmorethan200miles，fromnearthesiteofancientDaninthenorth，tothewater—partingattheheadoftheWadyArabahinthesouth；anditsdeepestpart，atthebottomofthebasinoftheDeadSea，lies2500feetbelowthesurfaceoftheadjacentMediterranean。ThelowestportionoftherimoftheJordan—ArabahvalleyissituatedatthevillageofElFuleh，257feetabovetheMediterranean。Everywhereelsethecircumjacentheightsrisetoaverymuchgreateraltitude。
Hence，ofthewaterwhichstoodovertheSyriantableland，whenasmuchdrainedoffascouldrunaway，enoughwouldremaintoforma\"Mere\"withoutanoutlet，2757feetdeep，overthepresentsiteoftheDeadSea。Fromthistimeforth，thelevelofthePalestinianmerecouldbeloweredonlybyevaporation。Itisanextremelyinterestingfact，whichhashappilyescapedcaptureforthepurposesoftheenergeticmisunderstanding，thatthevalley，atonetime，wasfilled，certainlywithin150feetofthisheight——probablyhigher。Anditisalmostequallycertain，thatthetimeatwhichthisgreatJordan—Arabahmerereacheditshighestlevelcoincideswiththeglacialepoch。Butthentheevidencewhichgoestoprovethis，alsoleadstotheconclusionthatthisstateofthingsobtainedataperiodconsiderablyolderthaneven4000B。C。，whentheworld，accordingtothe\"Helps\"（orshallwesay\"Hindrances\"）providedforthesimplestudentoftheBible，wascreated；thatitwasnotbroughtaboutbyanydiluvialcatastrophe，butwastheresultofachangeintherelativeactivitiesofcertainnaturaloperationswhicharequietlygoingonnow；andthat，sincethelevelofthemerebegantosink，manythousandyearsago，noseriouscatastropheofanydescriptionhasaffectedthevalley。
TheevidencethattheJordan—Arabahvalleyreallywasoncefilledwithwater，thesurfaceofwhichreachedwithin160feetofthelevelofthepassofJezrael，andpossiblystoodhigher，isthis：Remainsofalluvialstrata，containingshellsofthefreshwatermolluskswhichstillinhabitthevalley，worndownintoterracesbywaveswhichlongrippledatthesamelevel，andfurrowedbythechannelsexcavatedbymodernrainfalls，havebeenfoundattheformerheight；andtheyarerepeated，atintervals，lowerdown，untiltheGhor，orplainoftheJordan，itselfanalluvialdeposit，isreached。Thesestrataattainaconsiderablethickness；andtheyindicatethattheepochatwhichthefreshwatermereofPalestinereacheditshighestlevelisextremelyremote；thatitsdiminutionhastakenplaceveryslowly，andwithperiodsofrest，duringwhichthefirstformeddepositswerecutdownintoterraces。Thisconclusionisstrikinglyborneoutbyotherfacts。AvolcanicregionstretchesfromGalileetoGileadandtheHauran，oneachsideofthenorthernendofthevalley。Someofthestreamsofbasalticlavawhichhavebeenthrownoutfromitscratersandcleftsintimesofwhichhistoryhasnorecord，haverunathwartthecourseoftheJordanitself，orofthatofsomeofitstributarystreams。
Thelavastreams，therefore，mustbeoflaterdatethanthedepressionstheyfill。Andyet，wheretheyhavethustemporarilydammedtheJordanandtheJermuk，thesestreamshavehadtimetocutthroughthehardbasaltsandlaybarethebeds，overwhich，beforethelavastreamsinvadedthem，theyflowed。
Infact，theantiquityofthepresentJordan—Arabahvalley，asahollowinatableland，outofreachofthesea，andtroubledbynodiluvialorotherdisturbances，beyondthevolcaniceruptionsofGileadandofGalilee，isvast，evenasestimatedbyageologicalstandard。Nomarinedepositsoflaterthanmioceneageoccurinoraboutit；andthereiseveryreasontobelievethattheSyro—Arabianplateauhasbeendryland，throughouttheplioceneandlaterepochs，downtothepresenttime。
Raisedbeaches，containingrecentshells，ontheLevantineshoresoftheMediterraneanandonthoseoftheRedSea，testifytoageologicallyrecentchangeofthesealeveltotheextentof250or300feet，probablyproducedbytheslowelevationoftheland；and，asIhavealreadyremarked，thealluvialplainoftheEuphratesandTigrisappearstohavebeenaffectedinthesameway，thoughseeminglytoalessextent。Butofviolent，orcatastrophic，changethereisnotrace。Eventhevolcanicoutburstshaveflowedinevensheetsovertheoldlandsurface；
andthelonglinesofthehorizontalterraceswhichremain，testifytothegeologicalinsignificanceofsuchearthquakesashavetakenplace。Itis，indeed，possiblethattheoriginalformationofthevalleymayhavebeendeterminedbythewell—
knownfault，alongwhichthewesternrocksarerelativelydepressedandtheeasternelevated。But，whetherthatfaultwaseffectedslowlyorquickly，andwheneveritcameintoexistence，theexcavationofthevalleytoitspresentwidth，nolessthanthesculpturingofitssteepwallsandoftheinnumerabledeepravineswhichscorethemdowntotheverybottom，areindubitablyduetotheoperationofrainandstreams，duringanenormouslengthoftime，withoutinterruptionordisturbanceofanymagnitude。Thealluvialdepositswhichhavebeenmentionedarecontinuedintothelateralravines，andhavemoreorlessfilledthem。But，sincethewatershavebeenlowered，thesedepositshavebeencutdowntogreatdepths，andarestillbeingexcavatedbythepresenttemporary，orpermanent，streams。
Hence，itfollows，thatalltheseravinesmusthaveexistedbeforethetimeatwhichthevalleywasoccupiedbythegreatmere。ThisfactacquiresapeculiarimportancewhenweproceedtoconsiderthegroundsfortheconclusionthattheoldPalestinianmereattaineditshighestlevelinthecoldperiodofthepleistoceneepoch。ItiswellknownthatglaciersformerlycamelowdownontheflanksofLebanonandAntilebanon；
indeed，theoldmorainesarethehauntsofthefewsurvivorsofthefamouscedars。ThisimpliesaperennialsnowcapofgreatextentonHermon；therefore，avastlygreatersupplyofwatertothesourcesoftheJordanwhichriseonitsflanks；and，inaddition，suchatotalchangeinthegeneralclimate，thattheinnumerableWadys，nowtraversedonlybyoccasionalstormtorrents，musthavebeenoccupiedbyperennialstreams。Allthisinvolvesalowerannualtemperatureandamoistandrainyatmosphere。Ifsuchachangeofmeteorologicalconditionscouldbeeffectednow，whenthelossbyevaporationfromthesurfaceoftheDeadSeasalt—panbalancesallthegainfromtheJordanandotherstreams，thescalewouldbeturnedintheotherdirection。ThewatersoftheDeadSeawouldbecomediluted；
itslevelwouldrise；itwouldcover，firsttheplainoftheJordan，thenthelakeofGalilee，thenthemiddleJordanbetweenthislakeandthatofHuleh（theancientMerom）；and，finally，itwouldencroach，northwards，alongthecourseoftheupperJordan，and，southwards，uptheWadyArabah，untilitreachedsome260feetabovetheleveloftheMediterranean，whenitwouldattainapermanentlevel，bysendinganysuperfluitythroughthepassofJezraeltoswellthewatersoftheKishon，andflowthenceintotheMediterranean。
Reversetheprocess，inconsequenceoftheexcessoflossbyevaporationovergainbyinflow，whichmusthavesetinastheclimateofSyriachangedaftertheendofthepleistoceneepoch，and（withouttakingintoconsiderationanyothercircumstances）

TheevidenceofthegeneralstabilityofthephysicalconditionsofWesternAsia，whichisfurnishedbyPalestineandbytheEuphratesValley，isonlyfortifiedifweextendourviewnorthwardstotheBlackSeaandtheCaspian。TheCaspianisasortofmagnifiedreplicaoftheDeadSea。Thebottomofthedeepestpartofthisvastinlandmereisabout3000feetbelowtheleveloftheMediterranean，whileitssurfaceislowerby85
feet。Atpresent，itisseparated，onthewest，bywidespacesofdrylandfromtheBlackSea，whichhasthesameheightastheMediterranean；and，ontheeast，fromtheAral，138feetabovethatlevel。ThewatersoftheBlackSea，nowincommunicationwiththeMediterraneanbytheDardanellesandtheBosphorus，aresalt，butbecomebrackishnorthwards，wheretheriversofthesteppespourinagreatvolumeoffreshwater。ThoseoftheshallowernorthernhalfoftheCaspianaresimilarlyaffectedbytheVolgaandtheUral，while，intheshallowbaysofthesoutherndivision，theybecomeextremelysalineinconsequenceoftheintenseevaporation。TheAralSea，thoughsuppliedbytheJaxartesandtheOxus，hasbrackishwater。Thereisevidencethat，intheplioceneandpleistoceneperiods，togonofartherback，thestraitoftheDardanellesdidnotexist，andthatthevastarea，fromthevalleyoftheDanubetothatoftheJaxartes，wascoveredbybrackishor，insomeparts，freshwatertoaheightofatleast200feetabovetheleveloftheMediterranean。Atthepresenttime，thewater—partingwhichseparatesthenorthernpartofthebasinoftheCaspianfromthevastplainstraversedbytheTobolandtheObi，intheircoursetotheArcticOcean，appearstobelessthan200feetabovethelatter。Itwouldseem，therefore，tobeveryprobablethat，undertheclimatalconditionsofpartofthepleistoceneperiod，thevalleyoftheObiplayedthesamepartinrelationtothePonto—Araliansea，asthatoftheKishonmayhavedonetothegreatmereoftheJordanvalley；andthattheoutflowformedthechannelbywhichthewell—knownArcticelementsofthefaunaoftheCaspianenteredit。ForthefossilremainsimbeddedinthestratacontinuouslydepositedintheAralo—Caspianarea，sincethelatterendofthemioceneepoch，shownosignthat，fromthattimeonward，ithaseverbeencoveredbyseawater。
Therefore，thesuppositionofafreeinflowoftheArcticOcean，whichatonetimewasgenerallyreceived，aswellasthatofvarioushypotheticaldelugesfromthatquarter，mustbeseriouslyquestioned。
TheCaspianandtheAralstandinsomewhatthesamerelationtothevastbasinofdrylandinwhichtheylie，astheDeadSeaandthelakeofGalileetotheJordanvalley。Theyaretheremainsofavast，mostlybrackish，mere，whichhasdriedupinconsequenceoftheexcessofevaporationoversupply，sincethecoldanddampclimateofthepleistoceneepochgaveplacetotheincreasingdrynessandgreatsummerheatsofCentralAsiainmoremoderntimes。ThedesiccationoftheAralo—Caspianbasin，whichcommunicatedwiththeBlackSeaonlybyacomparativelynarrowandshallowstraitalongthepresentvalleyofManytsch，thebottomofwhichwaslessthan100feetabovetheMediterranean，musthavebeenvastlyaidedbytheerosionofthestraitoftheDardanellestowardstheendofthepleistoceneepoch，orperhapslater。FortheresultofthusopeningapassageforthewatersoftheBlackSeaintotheMediterraneanmusthavebeenthegradualloweringofitsleveltothatofthelattersea。WhenthisprocesshadgonesofarastobringdowntheBlackSeawatertowithinlessthanahundredfeetofitspresentlevel，thestraitofManytschceasedtoexist；andthevastbodyoffreshwaterbroughtdownbytheDanube，theDnieper，theDon，andotherSouthRussianriverswascutofffromtheCaspian，andeventuallydeliveredintotheMediterranean。Thus，thereisasconclusiveevidenceasonecanwellhopetoobtaininthesematters，that，northoftheEuphratesvalley，thephysicalgeographyofanareaaslargeasallCentralEuropehasremainedessentiallyunchanged，fromthemioceneperioddowntoourtime；justas，tothewestoftheEuphratesvalley，Palestinehasexhibitedasimilarpersistenceofgeographicaltype。Tothesouth，thevalleyoftheNiletellsexactlythesamestory。TheholesboredbymiocenemollusksinthecliffseastandwestofCairobearwitnessthat，inthemioceneepoch，itcontainedanarmofthesea，thebottomofwhichhassincebeengraduallyfilledupbythealluviumoftheNile，andelevatedtoitspresentposition。ButthehigherpartsoftheMokattamandofthedesertaboutGhizeh，havebeendrylandfromthattimetothis。ToolittleisknownofthegeologyofPersia，atpresent，toallowanypositiveconclusiontobeenunciated。But，takingthenametoindicatethewholecontinentalmassofIran，betweenthevalleysoftheIndusandtheEuphrates，thesuppositionthatitsphysicalgeographyhasremainedunchangedforanimmenselylongperiodishardlyrash。
Thecountryis，infact，anenormousbasin，surroundedonallsidesbyamountainousrim，andsubdividedwithinbyridgesintoplateausandhollows，thebottomofthedeepestofwhich，intheprovinceofSeistan，probablydescendstotheleveloftheIndianOcean。Thesedepressionsareoccupiedbysaltmarshesanddeserts，inwhichthewatersofthestreamswhichflowdownthesidesofthebasinarenowdissipatedbyevaporation。IamacquaintedwithnoevidencethatthepresentIranianbasinwaseveroccupiedbythesea；buttheaccumulationsofgraveloveragreatextentofitssurfaceindicatelong—continuedwateraction。Itis，therefore，afairpresumptionthatlargelakeshavecoveredmuchofitspresentdeserts，andthattheyhavedriedupbytheoperationofthesamechangedclimatalconditionsasthosewhichhavereducedtheCaspianandtheDeadSeatotheirpresentdimensions。
ThusitwouldseemthattheEuphratesvalley，thecentreofthefabledNoachiandeluge，isalsothecentreofaregioncoveringsomemillionsofsquaremilesofthepresentcontinentsofEurope，Asia，andAfrica，inwhichallthefacts，relevanttotheargument，atpresentknown，convergetotheconclusionthat，sincethemioceneepoch，theessentialfeaturesofitsphysicalgeographyhaveremainedunchanged；thatithasneitherbeendepressedbelowthesea，norsweptbydiluvialwaterssincethattime；andthattheChaldaeanversionofthelegendofafloodintheEuphratesvalleyis，ofallthosewhichareextant，theonlyonewhichisevenconsistentwithprobability，sinceitdepictsalocalinundation，notmoreseverethanonewhichmightbebroughtaboutbyaconcurrenceoffavourableconditionsatthepresentday；andwhichmightprobablyhavebeenmoreeasilyeffectedwhenthePersianGulfextendedfarthernorth。
Hence，therecoursetothe\"glacialepoch\"forsomeeventwhichmightcolourablyrepresentaflood，distinctlyassertedbytheonlyauthorityforittohaveoccurredinhistoricaltimes，ispeculiarlyunfortunate。EvenaWelshantiquarymighthesitateoverthesuppositionthatatraditionofthefateofMoelTryfaen，intheglacialepoch，hadfurnishedthebasisoffactforalegendwhicharoseamongpeoplewhoseownexperienceabundantlysuppliedthemwiththeneedfulprecedents。
Moreover，ifevidenceofinterchangesoflandandseaaretobeacceptedas\"confirmations\"ofNoah’sdeluge，thereareplentyofsourcesforthetraditiontobehadmuchnearerthanWales。
