ALIVINGinterrogation-pointandaborninvestigatorfromchildhood，Edisonhasneverbeenwithoutalaboratoryofsomekindforupwardofhalfacentury。
Inyouthfulyears，asalreadydescribedinthisbook，hebecameardentlyinterestedinchemistry，andevenattheearlyageoftwelvefeltthenecessityforaspecialnookofhisown，wherehecouldsatisfyhisunconvincedmindofthecorrectnessorinaccuracyofstatementsandexperimentscontainedinthefewtechnicalbooksthenathiscommand。
Ordinarilyhewaslikeothernormalladsofhisage——fullofboyish，heartyenjoyments——butwithalpossessedofanunquenchablespiritofinquiryandaninsatiabledesireforknowledge。Beingblessedwithawiseanddiscerningmother，hisaspirationswereencouraged；andhewasallowedacornerinhercellar。Itisfairtooffertributeheretoherbraveryaswellastoherwisdom，forattimesshewasinmortalterrorlesttheprecociousexperimenterbelowshould，inhisinexperience，makesomeawfulcombinationthatwouldexplodeandbringdownthehouseinruinsonhimselfandtherestofthefamily。
Fortunatelynosuchcatastrophehappened，butyoungEdisonworkedawayinhisembryoniclaboratory，satisfyinghissoulandincidentallydepletinghislimitedpocket-moneytothevanishing-point。Itwas，indeed，owingtothislattercircumstancethatinayearortwohisaspirationsnecessitatedanincreaseofrevenue；andaconsequentdeterminationtoearnsomemoneyforhimselfledtohisfirstrealcommercialenterpriseas“candybutcher“ontheGrandTrunkRailroad，alreadymentionedinapreviouschapter。
Ithasalsobeenrelatedhowhispreciouslaboratorywastransferredtothetrain；howheanditweresubsequentlyexpelled；andhowitwasre-establishedinhishome，wherehecontinuedstudiesandexperimentsuntilthebeginningofhiscareerasatelegraphoperator。
Thenomadiclifeofthenextfewyearsdidnotlessenhisdevotiontostudy；butitstoodseriouslyinthewayofsatisfyingtheever-presentcravingforalaboratory。Thelackofsuchaplaceneverpreventedexperimentation，however，aslongashehadadollarinhispocketandsomeavailable“holeinthewall。“Withtheturningofthetideoffortunethatsuddenlycarriedhim，inNewYorkin1869，frompovertytotheopulenceof$300amonth，hedrewnearertoarealizationofhischerishedambitioninhavingmoney，place，andsometimestolenfromsleepformoreseriousexperimenting。Thusmatterscontinueduntil，atabouttheageoftwenty-two，Edison'sinventionshadbroughthimarelativelylargesumofmoney，andhebecameaverybusymanufacturer，andlesseeofalargeshopinNewark，NewJersey。
Now，forthefirsttimesinceleavingthatboyishlaboratoryintheoldhomeatPortHuron，Edisonhadaplaceofhisowntoworkin，tothinkin；butnooneinanywayacquaintedwithNewarkasaswarmingcentreofmiscellaneousandmultitudinousindustrieswouldrecommenditasacloisteredretreatforbroodingreverieandintrospection，favorabletocreativeeffort。Somepeoplerevelinsurroundingsofhustleandbustle，andfindthereinnohindrancetogreataccomplishment。TheelectricalgeniusofNewarkisEdwardWeston，whohasthrivenamiditsturmoilandtherehasdevelopedhisbeautifulinstrumentsofprecision；justasBrushworkedouthisarc-lightingsysteminCleveland；orevenasFaraday，surroundedbythedinandroarofLondon，laidtheintellectualfoundationsofthewholemodernscienceofdynamicelectricity。ButEdison，thoughdeaf，couldnotmaketoohurriedaretreatfromNewarktoMenloPark，where，asiftojustifyhischangeofbase，vitalinventionssooncamethickandfast，yearafteryear。ThestoryofMenlohasbeentoldinanotherchapter，butthepointwasnotemphasizedthatEdisonthen，aslater，triedhardtodropmanufacturing。Hewouldinfinitelyratherbephilosopherthanproducer；butsomehowthenecessityofmanufacturingisconstantlythrustbackuponhimbyaprofound——perhapsfinical——senseofdissatisfactionwithwhatotherpeoplemakeforhim。Theworldneversawamanmoredeeplyanddesperatelyconvincedthatnothinginitapproachesperfection。Edisonisthedoctrineofevolutionincarnate，appliedtomechanics。AstotheremovalfromNewark，hemaybeallowedtotellhisownstory：“IhadashopatNewarkinwhichImanufacturedstocktickersandsuchthings。WhenImovedtoMenloParkItookoutonlythemachinerythatwouldbenecessaryforexperimentalpurposesandleftthemanufacturingmachineryintheplace。Itconsistedofmanymillingmachinesandothertoolsforduplicating。Irentedthistoamanwhohadformerlybeenmybookkeeper，andwhothoughthecouldmakemoneyoutofmanufacturing。Therewasabout$10，000worthofmachinery。Hewastopayme$2000ayearfortherentofthemachineryandkeepitingoodorder。
AfterImovedtoMenloPark，Iwasverybusywiththetelephoneandphonograph，andIpaidnoattentiontothislittlearrangement。Aboutthreeyearsafterward，itoccurredtomethatIhadnotheardatallfromthemanwhohadrentedthismachinery，soIthoughtIwouldgoovertoNewarkandseehowthingsweregoing。WhenIgotthere，Ifoundthatinsteadofbeingamachineshopitwasahotel！I

Alwaysashrewd，observant，andkindlycriticofcharacter，EdisontellsmanyanecdotesofthemenwhogatheredaroundhiminvariouscapacitiesatthatquietcornerofNewJersey——MenloPark——andlateratOrange，intheLlewellynParklaboratory；
