THEGUNCLUB

DuringtheWaroftheRebellion,anewandinfluentialclubwasestablishedinthecityofBaltimoreintheStateofMaryland。

Itiswellknownwithwhatenergythetasteformilitarymattersbecamedevelopedamongthatnationofship-owners,shopkeepers,andmechanics。Simpletradesmenjumpedtheircounterstobecomeextemporizedcaptains,colonels,andgenerals,withouthavingeverpassedtheSchoolofInstructionatWestPoint;

nevertheless;theyquicklyrivaledtheircompeersoftheoldcontinent,and,likethem,carriedoffvictoriesbydintoflavishexpenditureinammunition,money,andmen。

ButthepointinwhichtheAmericanssingularlydistancedtheEuropeanswasinthescienceofgunnery。Not,indeed,thattheirweaponsretainedahigherdegreeofperfectionthantheirs,butthattheyexhibitedunheard-ofdimensions,andconsequentlyattainedhithertounheard-ofranges。Inpointofgrazing,plunging,oblique,orenfilading,orpoint-blankfiring,theEnglish,French,andPrussianshavenothingtolearn;buttheircannon,howitzers,andmortarsaremerepocket-pistolscomparedwiththeformidableenginesoftheAmericanartillery。

Thisfactneedsurprisenoone。TheYankees,thefirstmechaniciansintheworld,areengineers——justastheItaliansaremusiciansandtheGermansmetaphysicians——byrightofbirth。

Nothingismorenatural,therefore,thantoperceivethemapplyingtheiraudaciousingenuitytothescienceofgunnery。

WitnessthemarvelsofParrott,Dahlgren,andRodman。

TheArmstrong,Palliser,andBeaulieugunswerecompelledtobowbeforetheirtransatlanticrivals。

NowwhenanAmericanhasanidea,hedirectlyseeksasecondAmericantoshareit。Iftherebethree,theyelectapresidentandtwosecretaries。Givenfour,theynameakeeperofrecords,andtheofficeisreadyforwork;five,theyconveneageneralmeeting,andtheclubisfullyconstituted。SothingsweremanagedinBaltimore。Theinventorofanewcannonassociatedhimselfwiththecasterandtheborer。Thuswasformedthenucleusofthe"GunClub。"Inasinglemonthafteritsformationitnumbered1,833effectivemembersand30,565correspondingmembers。

Oneconditionwasimposedasa_sinequanon_uponeverycandidateforadmissionintotheassociation,andthatwastheconditionofhavingdesigned,or(moreorless)perfectedacannon;or,indefaultofacannon,atleastafirearmofsomedescription。Itmay,however,bementionedthatmereinventorsofrevolvers,fire-shootingcarbines,andsimilarsmallarms,metwithlittleconsideration。Artilleristsalwayscommandedthechiefplaceoffavor。

Theestimationinwhichthesegentlemenwereheld,accordingtooneofthemostscientificexponentsoftheGunClub,was"proportionaltothemassesoftheirguns,andinthedirectratioofthesquareofthedistancesattainedbytheirprojectiles。"

TheGunCluboncefounded,itiseasytoconceivetheresultoftheinventivegeniusoftheAmericans。Theirmilitaryweaponsattainedcolossalproportions,andtheirprojectiles,exceedingtheprescribedlimits,unfortunatelyoccasionallycutintwosomeunoffendingpedestrians。Theseinventions,infact,leftfarintherearthetimidinstrumentsofEuropeanartillery。

ItisbutfairtoaddthattheseYankees,braveastheyhaveeverprovedthemselvestobe,didnotconfinethemselvestotheoriesandformulae,butthattheypaidheavily,_inpropriapersona_,fortheirinventions。Amongthemweretobecountedofficersofallranks,fromlieutenantstogenerals;militarymenofeveryage,fromthosewhowerejustmakingtheir_debut_

intheprofessionofarmsuptothosewhohadgrownoldinthegun-carriage。Manyhadfoundtheirrestonthefieldofbattlewhosenamesfiguredinthe"BookofHonor"oftheGunClub;andofthosewhomadegoodtheirreturnthegreaterproportionborethemarksoftheirindisputablevalor。Crutches,woodenlegs,artificialarms,steelhooks,caoutchoucjaws,silvercraniums,platinumnoses,werealltobefoundinthecollection;anditwascalculatedbythegreatstatisticianPitcairnthatthroughouttheGunClubtherewasnotquiteonearmbetweenfourpersonsandtwolegsbetweensix。

Nevertheless,thesevaliantartilleriststooknoparticularaccountoftheselittlefacts,andfeltjustlyproudwhenthedespatchesofabattlereturnedthenumberofvictimsatten-foldthequantityofprojectilesexpended。

Oneday,however——sadandmelancholyday!——peacewassignedbetweenthesurvivorsofthewar;thethunderofthegunsgraduallyceased,themortarsweresilent,thehowitzersweremuzzledforanindefiniteperiod,thecannon,withmuzzlesdepressed,werereturnedintothearsenal,theshotwererepiled,allbloodyreminiscenceswereeffaced;thecotton-plantsgrewluxuriantlyinthewell-manuredfields,allmourninggarmentswerelaidaside,togetherwithgrief;andtheGunClubwasrelegatedtoprofoundinactivity。

Somefewofthemoreadvancedandinveteratetheoristssetthemselvesagaintoworkuponcalculationsregardingthelawsofprojectiles。Theyrevertedinvariablytogiganticshellsandhowitzersofunparalleledcaliber。Stillindefaultofpracticalexperiencewhatwasthevalueofmeretheories?

Consequently,theclubroomsbecamedeserted,theservantsdozedintheantechambers,thenewspapersgrewmouldyonthetables,soundsofsnoringcamefromdarkcorners,andthemembersoftheGunClub,erstwhilesonoisyintheirseances,werereducedtosilencebythisdisastrouspeaceandgavethemselvesupwhollytodreamsofaPlatonickindofartillery。

REPLYFROMTHEOBSERVATORYOFCAMBRIDGE

Barbicane,however,lostnotonemomentamidalltheenthusiasmofwhichhehadbecometheobject。Hisfirstcarewastoreassemblehiscolleaguesintheboard-roomoftheGunClub。

There,aftersomediscussion,itwasagreedtoconsulttheastronomersregardingtheastronomicalpartoftheenterprise。

Theirreplyonceascertained,theycouldthendiscussthemechanicalmeans,andnothingshouldbewantingtoensurethesuccessofthisgreatexperiment。

Anotecouchedinpreciseterms,containingspecialinterrogatories,wasthendrawnupandaddressedtotheObservatoryofCambridgeinMassachusetts。Thiscity,wherethefirstuniversityoftheUnitedStateswasfounded,isjustlycelebratedforitsastronomicalstaff。Therearetobefoundassembledallthemosteminentmenofscience。HereistobeseenatworkthatpowerfultelescopewhichenabledBondtoresolvethenebulaofAndromeda,andClarketodiscoverthesatelliteofSirius。ThiscelebratedinstitutionfullyjustifiedonallpointstheconfidencereposedinitbytheGunClub。

So,aftertwodays,thereplysoimpatientlyawaitedwasplacedinthehandsofPresidentBarbicane。

Itwascouchedinthefollowingterms:

_TheDirectoroftheCambridgeObservatorytothePresidentoftheGunClubatBaltimore。_

CAMBRIDGE,October7。

Onthereceiptofyourfavorofthe6thinstant,addressedtotheObservatoryofCambridgeinthenameofthemembersoftheBaltimoreGunClub,ourstaffwasimmediatelycalledtogether,anditwasjudgedexpedienttoreplyasfollows:

Thequestionswhichhavebeenproposedtoitarethese——

"1。Isitpossibletotransmitaprojectileuptothemoon?

"2。Whatistheexactdistancewhichseparatestheearthfromitssatellite?

"3。Whatwillbetheperiodoftransitoftheprojectilewhenendowedwithsufficientinitialvelocity?and,consequently,atwhatmomentoughtittobedischargedinorderthatitmaytouchthemoonataparticularpoint?

"4。Atwhatprecisemomentwillthemoonpresentherselfinthemostfavorablepositiontobereachedbytheprojectile?

"5。Whatpointintheheavensoughtthecannontobeaimedatwhichisintendedtodischargetheprojectile?

"6。Whatplacewillthemoonoccupyintheheavensatthemomentoftheprojectile\'sdeparture?"

Regardingthe_first_question,"Isitpossibletotransmitaprojectileuptothemoon?"

_Answer。_——Yes;provideditpossessaninitialvelocityof1,200yardspersecond;calculationsprovethattobesufficient。

Inproportionaswerecedefromtheearththeactionofgravitationdiminishesintheinverseratioofthesquareofthedistance;

thatistosay,_atthreetimesagivendistancetheactionisninetimesless。_Consequently,theweightofashotwilldecrease,andwillbecomereducedto_zero_attheinstantthattheattractionofthemoonexactlycounterpoisesthatoftheearth;thatistosayat47/52ofitspassage。Atthatinstanttheprojectilewillhavenoweightwhatever;and,ifitpassesthatpoint,itwillfallintothemoonbythesoleeffectofthelunarattraction。

The_theoreticalpossibility_oftheexperimentisthereforeabsolutelydemonstrated;its_success_mustdependuponthepoweroftheengineemployed。

Astothe_second_question,"Whatistheexactdistancewhichseparatestheearthfromitssatellite?"

_Answer。_——Themoondoesnotdescribea_circle_roundtheearth,butratheran_ellipse_,ofwhichourearthoccupiesoneofthe_foci_;theconsequence,therefore,is,thatatcertaintimesitapproachesnearerto,andatothersitrecedesfartherfrom,theearth;inastronomicallanguage,itisatonetimein_apogee_,atanotherin_perigee_。Nowthedifferencebetweenitsgreatestanditsleastdistanceistooconsiderabletobeleftoutofconsideration。Inpointoffact,initsapogeethemoonis247,552miles,andinitsperigee,218,657milesonlydistant;afactwhichmakesadifferenceof28,895miles,ormorethanone-ninthoftheentiredistance。Theperigeedistance,therefore,isthatwhichoughttoserveasthebasisofallcalculations。

Tothe_third_question。

_Answer。_——Iftheshotshouldpreservecontinuouslyitsinitialvelocityof12,000yardspersecond,itwouldrequirelittlemorethanninehourstoreachitsdestination;but,inasmuchasthatinitialvelocitywillbecontinuallydecreasing,itwilloccupy300,000seconds,thatis83hrs。20m。inreachingthepointwheretheattractionoftheearthandmoonwillbe_inequilibrio_。Fromthispointitwillfallintothemoonin50,000seconds,or13hrs。53m。20sec。Itwillbedesirable,therefore,todischargeit97hrs。13m。20sec。beforethearrivalofthemoonatthepointaimedat。

Regardingquestion_four_,"Atwhatprecisemomentwillthemoonpresentherselfinthemostfavorableposition,etc。?"

Onthe_fifth_question,"Atwhatpointintheheavensoughtthecannontobeaimed?"

_Answer。_——Theprecedingremarksbeingadmitted,thecannonoughttobepointedtothezenithoftheplace。Itsfire,therefore,willbeperpendiculartotheplaneofthehorizon;

TheseareouranswerstothequestionsproposedtotheObservatoryofCambridgebythemembersoftheGunClub:

Tosumup——

1st。Thecannonoughttobeplantedinacountrysituatedbetween0@and28@ofN。orS。lat。

theseatomscombinedtogetherchemicallyaccordingtotheiraffinities,formedthemselvesintomolecules,andcomposedthosenebulousmasseswithwhichthedepthsoftheheavensarestrewed。

Thesemassesbecameimmediatelyenduedwitharotarymotionaroundtheirowncentralpoint。Thiscenter,formedofindefinitemolecules,begantorevolvearounditsownaxisduringitsgradualcondensation;then,followingtheimmutablelawsofmechanics,inproportionasitsbulkdiminishedbycondensation,itsrotarymotionbecameaccelerated,andthesetwoeffectscontinuing,theresultwastheformationofoneprincipalstar,thecenterofthenebulousmass。

Byattentivelywatching,theobserverwouldthenhaveperceivedtheothermoleculesofthemass,followingtheexampleofthiscentralstar,becomelikewisecondensedbygraduallyacceleratedrotation,andgravitatingrounditintheshapeofinnumerablestars。

Thuswasformedthe_Nebulae_,ofwhichastronomershavereckonedupnearly5,000。

Amongthese5,000nebulaethereisonewhichhasreceivedthenameoftheMilkyWay,andwhichcontainseighteenmillionsofstars,eachofwhichhasbecomethecenterofasolarworld。

Iftheobserverhadthenspeciallydirectedhisattentiontooneofthemorehumbleandlessbrilliantofthesestellarbodies,astarofthefourthclass,thatwhichisarrogantlycalledtheSun,allthephenomenatowhichtheformationoftheUniverseistobeascribedwouldhavebeensuccessivelyfulfilledbeforehiseyes。

Infact,hewouldhaveperceivedthissun,asyetinthegaseousstate,andcomposedofmovingmolecules,revolvingrounditsaxisinordertoaccomplishitsworkofconcentration。Thismotion,faithfultothelawsofmechanics,wouldhavebeenacceleratedwiththediminutionofitsvolume;andamomentwouldhavearrivedwhenthecentrifugalforcewouldhaveoverpoweredthecentripetal,whichcausesthemoleculesalltotendtowardthecenter。

Anotherphenomenonwouldnowhavepassedbeforetheobserver\'seye,andthemoleculessituatedontheplaneoftheequator,escapinglikeastonefromaslingofwhichthecordhadsuddenlysnapped,wouldhaveformedaroundthesunsundryconcentricringsresemblingthatofSaturn。Intheirturn,again,theseringsofcosmicalmatter,excitedbyarotarymotionaboutthecentralmass,wouldhavebeenbrokenupanddecomposedintosecondarynebulosities,thatistosay,intoplanets。Similarlyhewouldhaveobservedtheseplanetsthrowoffoneormoreringseach,whichbecametheoriginofthesecondarybodieswhichwecallsatellites。

Thus,then,advancingfromatomtomolecule,frommoleculetonebulousmass,fromthattoprincipalstar,fromstartosun,fromsuntoplanet,andhencetosatellite,wehavethewholeseriesoftransformationsundergonebytheheavenlybodiesduringthefirstdaysoftheworld。

Now,ofthoseattendantbodieswhichthesunmaintainsintheirellipticalorbitsbythegreatlawofgravitation,somefewinturnpossesssatellites。Uranushaseight,Saturneight,Jupiterfour,Neptunepossiblythree,andtheEarthone。Thislast,oneoftheleastimportantoftheentiresolarsystem,wecalltheMoon;anditisshewhomthedaringgeniusoftheAmericansprofessedtheirintentionofconquering。

Themoon,byhercomparativeproximity,andtheconstantlyvaryingappearancesproducedbyherseveralphases,hasalwaysoccupiedaconsiderableshareoftheattentionoftheinhabitantsoftheearth。

FromthetimeofThalesofMiletus,inthefifthcenturyB。C。,downtothatofCopernicusinthefifteenthandTychoBraheinthesixteenthcenturyA。D。,observationshavebeenfromtimetotimecarriedonwithmoreorlesscorrectness,untilinthepresentdaythealtitudesofthelunarmountainshavebeendeterminedwithexactitude。Galileoexplainedthephenomenaofthelunarlightproducedduringcertainofherphasesbytheexistenceofmountains,towhichheassignedameanaltitudeof27,000feet。AfterhimHevelius,anastronomerofDantzic,reducedthehighestelevationsto15,000feet;butthecalculationsofRicciolibroughtthemupagainto21,000feet。

AtthecloseoftheeighteenthcenturyHerschel,armedwithapowerfultelescope,considerablyreducedtheprecedingmeasurements。

Heassignedaheightof11,400feettothemaximumelevations,andreducedthemeanofthedifferentaltitudestolittlemorethan2,400feet。ButHerschel\'scalculationswereintheirturncorrectedbytheobservationsofHalley,Nasmyth,Bianchini,Gruithuysen,andothers;butitwasreservedforthelaborsofBoeerandMaedlerfinallytosolvethequestion。Theysucceededinmeasuring1,905differentelevations,ofwhichsixexceed15,000feet,andtwenty-twoexceed14,400feet。Thehighestsummitofalltowerstoaheightof22,606feetabovethesurfaceofthelunardisc。Atthesameperiodtheexaminationofthemoonwascompleted。Sheappearedcompletelyriddledwithcraters,andheressentiallyvolcaniccharacterwasapparentateachobservation。

Theabsenceofairentailstheabsenceofwater。Itbecame,therefore,manifestthattheSelenites,tosupportlifeundersuchconditions,mustpossessaspecialorganizationoftheirown,mustdifferremarkablyfromtheinhabitantsoftheearth。

Atlength,thankstomodernart,instrumentsofstillhigherperfectionsearchedthemoonwithoutintermission,notleavingasinglepointofhersurfaceunexplored;andnotwithstandingthatherdiametermeasures2,150miles,hersurfaceequalstheone-fifteenthpartofthatofourglobe,andherbulktheone-forty-ninthpartofthatoftheterrestrialspheroid——notoneofhersecretswasabletoescapetheeyesoftheastronomers;andtheseskillfulmenofsciencecarriedtoanevengreaterdegreetheirprodigiousobservations。

Onewouldhavethoughtthatthemoonhadjustappearedforthefirsttime,andthatnoonehadeverbeforecaughtaglimpseofherintheheavens。Thepapersrevivedalltheoldanecdotesinwhichthe"sunofthewolves"playedapart;theyrecalledtheinfluenceswhichtheignoranceofpastagesascribedtoher;inshort,allAmericawasseizedwithselenomania,orhadbecomemoon-mad。

Thescientificjournals,fortheirpart,dealtmoreespeciallywiththequestionswhichtouchedupontheenterpriseoftheGunClub。

TheletteroftheObservatoryofCambridgewaspublishedbythem,andcommenteduponwithunreservedapproval。

Untilthattimemostpeoplehadbeenignorantofthemodeinwhichthedistancewhichseparatesthemoonfromtheearthiscalculated。

Theytookadvantageofthisfacttoexplaintothemthatthisdistancewasobtainedbymeasuringtheparallaxofthemoon。

Thetermparallaxproving"caviaretothegeneral,"theyfurtherexplainedthatitmeanttheangleformedbytheinclinationoftwostraightlinesdrawnfromeitherextremityoftheearth\'sradiustothemoon。Ondoubtsbeingexpressedastothecorrectnessofthismethod,theyimmediatelyprovedthatnotonlywasthemeandistance234,347miles,butthatastronomerscouldnotpossiblybeinerrorintheirestimatebymorethanseventymileseitherway。

Themotionofrotationisthatwhichproducesdayandnightonthesurfaceofthemoon;savethatthereisonlyonedayandonenightinthelunarmonth,eachlastingthreehundredandfifty-fourandone-thirdhours。But,happilyforher,thefaceturnedtowardtheterrestrialglobeisilluminatedbyitwithanintensityequaltothatoffourteenmoons。Astotheotherface,alwaysinvisibletous,ithasofnecessitythreehundredandfifty-fourhoursofabsolutenight,temperedonlybythat"paleglimmerwhichfallsuponitfromthestars。"

Somewell-intentioned,butratherobstinatepersons,couldnotatfirstcomprehendhow,ifthemoondisplaysinvariablythesamefacetotheearthduringherrevolution,shecandescribeoneturnroundherself。Tosuchtheyanswered,"Gointoyourdining-room,andwalkroundthetableinsuchawayastoalwayskeepyourfaceturnedtowardthecenter;bythetimeyouwillhaveachievedonecompleteroundyouwillhavecompletedoneturnaroundyourself,sinceyoureyewillhavetraversedsuccessivelyeverypointoftheroom。Well,then,theroomistheheavens,thetableistheearth,andthemoonisyourself。"

Regardingthealtitudewhichthemoonattainsabovethehorizon,theletteroftheCambridgeObservatoryhadsaidallthatwastobesaidinthisrespect。Everyoneknewthatthisaltitudevariesaccordingtothelatitudeoftheobserver。Buttheonlyzonesoftheglobeinwhichthemoonpassesthezenith,thatis,thepointdirectlyovertheheadofthespectator,areofnecessitycomprisedbetweenthetwenty-eighthparallelsandtheequator。Hencetheimportanceoftheadvicetotrytheexperimentuponsomepointofthatpartoftheglobe,inorderthattheprojectilemightbedischargedperpendicularly,andsothesoonestescapetheactionofgravitation。Thiswasanessentialconditiontothesuccessoftheenterprise,andcontinuedactivelytoengagethepublicattention。

Regardingthepathdescribedbythemooninherrevolutionroundtheearth,theCambridgeObservatoryhaddemonstratedthatthispathisare-enteringcurve,notaperfectcircle,butanellipse,ofwhichtheearthoccupiesoneofthe_foci_。Itwasalsowellunderstoodthatitisfarthestremovedfromtheearthduringits_apogee_,andapproachesmostnearlytoitatits_perigee_。

SuchwasthentheextentofknowledgepossessedbyeveryAmericanonthesubject,andofwhichnoonecoulddecentlyprofessignorance。Still,whiletheseprincipleswerebeingrapidlydisseminatedmanyerrorsandillusoryfearsprovedlesseasytoeradicate。

Forinstance,someworthypersonsmaintainedthatthemoonwasanancientcometwhich,indescribingitselongatedorbitroundthesun,happenedtopassneartheearth,andbecameconfinedwithinhercircleofattraction。Thesedrawing-roomastronomersprofessedtoexplainthecharredaspectofthemoon——adisasterwhichtheyattributedtotheintensityofthesolarheat;only,onbeingremindedthatcometshaveanatmosphere,andthatthemoonhaslittleornone,theywerefairlyatalossforareply。

Hencetheyconcluded,logicallyenough,thatanaccelerationofmotionoughttobeaccompaniedbyacorrespondingdiminutioninthedistanceseparatingthetwobodies;andthat,supposingthedoubleeffecttobecontinuedtoinfinity,themoonwouldendbyonedayfallingintotheearth。However,theybecamereassuredastothefateoffuturegenerationsonbeingapprisedthat,accordingtothecalculationsofLaplace,thisaccelerationofmotionisconfinedwithinveryrestrictedlimits,andthataproportionaldiminutionofspeedwillbecertaintosucceedit。
