　　To　thee　be　the　glory；　because　the　love　of　life　was　brighter　before　thy　face　than　the　fear　of　death　was　dark。　Thou　art　Demeter　and　Hertha　and　Isis；　Cybele　of　the　Lions；　and　the　Mountain…Mother。　From　thy　daughters　shall　spring　tribes；　and　from　thy　grandsons；　nations！　Thy　name　is　The　Mother；　and　they　shall　call　thee　blessed。　
　　There　will　be　laughter　and　song　again。　Maidens　will　walk　in　the　meadows；　young　men；　leap　by　the　brooks。　Their　children's　children　shall　be　again　as　the　pine　trees　of　the　mountainside。　They　shall　call　thee　blessed；　because　in　a　dark　time　thy　look　was　toward　the　light。　
　　While　they　were　still　uncertain；　Em　looked　out　one　morning　and　said；　〃See；　some　rats！〃　
　　He　looked。　Sure　enough；　two　rats　were　nosing　their　way　along　the　base　of　the　hedge；　foraging　about　or　merely　investigating。　Em　pointed　out　the　rats　to　Princess　through　the　window；　and　then　opened　the　door。　But　being　a　dog　who　gave　tongue　to　tell　the　hunter　where　the　chase　was　leading；　she　leaped　out　baying；　and　the　rats　vanished　before　she　was　anywhere　near　them。　
　　That　afternoon　they　saw　more　rats　at　several　times；　one　place　and　another；　near　the　house；　in　the　street；　or　running　in　the　gardens。　
　　Next　morning　the　wave　had　engulfed　them。　Rats　were　everywhere。　These　were　merely　ordinary…looking　rats；　no　larger　or　smaller　than　rats　were　expected　to　be；　not　particularly　fat　or　particularly　lean…just　rats。　Ish　thought　of　the　way　the　ants　had　been　some　time　ago；　and　felt　a　cold　shiver　run　through　him。　
　　The　only　thing　to　do　was　to　make　an　investigation；　and　thus　render　the　rats　less　horrible；　because　when　you　knew　sometlung　about　the　situation；　you　saw　the　interest　that　lay　in　it。　
　　In　the　station…wagon　they　drove　about　here　and　there；　often　crushing　some　rat　which　decided　to　dash　across　the　street；　just　ahead　of　their　fires。　At　first　they　shuddered　a　little　at　the　soft　squash；　and　looked　at　each　other；　but　before　long　it　had　bee　so　mon　that　they　thought　nothing　about　it。　The　area　which　the　rats　were　occupying　was　roughly　the　city；　although　they　spread　outward　from　the　built…up　area；　covering　somewhat　larger　an　area　than　the　ants　had　done。　…　
　　What　had　happened；　in　general；　was　clear　enough。　Ish　remembered　some　kind　of　statistics　which　declared　that　the　number　of　rats　in　a　city　was　generally　about　equal　to　the　number　of　people。　
　　〃Well；〃　he　explained　to　Em；　〃you　start　then　with；　say；　a　million　rats；　half　of　them　being　does　or　bitches　or　whatever　you　call　lady　rats。　Some　of　the　stores　and　warehouses　are　rat…proof；　but　still　there　has　been　for　all　this　tune　what　you　can　call　an　unlimited　supply　of　food。〃　
　　〃Then　how　many　rats　should　there　be　now？〃　
　　〃I　can't　do　that　problem　in　my　head。　I'll　try　later。〃　
　　That　evening　at　home　he　sat　down　to　it　as　a　mathematical　problem。　With　the　aid　of　his　father's　encyclopedia　he　determined　that　rats　had　approximately　one　litter　a　month；　with　an　average　of　about　ten　young。　That　is；　one　month　of　uninterrupted　breeding　might　have　produced　about　a　population　of　ten　million　rats　in　this　given　area。　These　young　females；　in　turn；　would　begin　to　breed　before　they　reached　the　age　of　two　months。　There　must　be　some　casualties；　of　course；　and　he　had　no　way　of　determining　just　how　many　of　the　rats　would　live　to　maturity　But；　c：ertainly　the　increase　must　be　prodigious　under　the　circumstances。　His　mathematics　broke　down。　
　　But　even　if　the　rats　should　only　be　increasing　at　the　rate　of　doubling　their　numbers　every　month；　an　estimate　which　seemed　ridiculously　conservative；　there　should　by　this　time　be　already　somewhere　in　the　neighborhood　of　fifty　million。　If　they　were　increasing　threefold　each　month；　an　estimate　which　still　seemed　conservative；　there　would　now　be　in　the　area　approximately　one　billion　rats。　
　　As　he　considered　the　problem；　he　saw　no　reason　at　all　why。　the　rats；　with　unlimited　food；　might　not　possibly　quadruple　their　numbers　every　month。　In　the　Old　Times　man　had　been　the　only　important　natural　enemy　of　the　city　rats；　and　even　man　had　had　to　maintain　constant　war　against　them　to　keep　their　numbers　under　control。　With　man　gone；　their　only　enemies　would　have　been　the　small　number　of　dogs　whose　instinct　led　them　to　catch　rats；　and　somewhat　larger　number　of　cats。　But　here　a　secondary　result　must　have　influenced　the　situation　in　favor　of　the　rats。　As　he　had　noticed；　the　rat…catching　dogs　seemed　to　hold　the　ground　alone　without　the　help　of　any　cats。　Probably　the　dogs　had　killed　the　cats　as　much　as　they　had　the　rats；　and　so　had　eliminated　the　chief　control。　And　in　the　end；　the　dogs　themselves　had　probably　been　overwhelmed　in　the　mere　increase　of　numbers。　Now　he　no　longer　saw　any　dogs。　It　seemed　unlikely　that　they　had　actually　been　killed　by　the　rats；　although　the　rats　may　very　well　have　cleaned　out　many　litters　of　puppies。　Probably；　the　dogs　had　merely　retreated　before　the　swarms　of　rats；　and　were　still　hanging　around　on　the　outskirts；　now　having　been　driven　from　the　city　into　the　suburbs。　
　　Whether　there　were　a　billion　rats　or　only　fifty　million　made　very　little　difference。　There　certainly　were　too　many　rats；　and　Ish　and　Em　felt　themselves　in　a　state　of　siege。　They　watched　all　the　doors　carefully。　Nevertheless；　one　rat　appeared　in　the　kitchen　from　some　unknown　quarter；　and　they　had　a　mad　scurry　as　Ish　pursued　it　with　a　broom。　Cornered；　it　leaped　viciously　at　the　broom…handle；　and　left　teeth　marks　in　the　hard　wood　before　he　was　able　to　crush　it　against　the　floor。　
　　After　a　few　days；　moreover；　they　began　to　see　a　kind　of　difference；　both　in　the　appearance　and　in　the　behavior　of　the　rats。　Apparently；　the　supplies　of　food；　vast　though　they　were；　had　at　last　begun　to　yield　before　the　attack　of　an　ever…pyramiding　number　of　rats。　The　rats　now　appeared　thinner；　and　they　ran　around　even　more　feverishly　in　search　of　food。　They　began　to　burrow　in　the　ground。　They　dug　up　the　tulip　bulbs；　first　of　all；　seeming　particularly　fond　of　them。　Then　they　attacked　the　less　palatable　bulbs　and　roots。　They　ran　along　the　branches　of　the　trees；　apparently　eating　any　insects　they　could　find　or　any　remains　of　seeds　or　fruit。　They　even；　at　last；　began　to　gnaw　the　bark　of　young　trees；　like　rabbits。　
　　Ish　parked　the　car　as　close　to　the　house　as　he　could　now；　and　made　a　dash　for　it；　wearing　high　boots。　But　actually　the　rats　never　made　any　attempt　at　an　attack。　Ish　kept　Princess　in　the　house　mostly；　although　the　rats　had　offered　her　no　violence　either。　
　　Still　driving　about　to　investigate；　Ish　became　more　and　more　accustomed　to　the　soft　squash　beneath　his　tires。　He　began　to　feel　as　if　he　were　plastering　the　streets　with　a　continuous　line　of　crushed　rats。　In　the　angle　of　two　walls；　as　he　drove　slowly　by；　a　small　white　object　caught　his　attention。　Stopping　the　car　and　looking　carefully；　he　saw　that　it　was　the　skull　of　some　small　dog。　The　long　teeth；　still　shining　white；　indicated　that　it　had　probably　been　a　terrier。　Apparently；　the　rats　had　cornered　the　dog　in　the　angle　of　the　walls；　or　else；　the　dog　'　fighting　for　its　life；　had　retreated　there。　Whether　the　rats　had　dared　attack　a　strong　and　healthy　dog；　Ish　could　not　know。　Perhaps　it　had　suffered　an　accident　or　had　been　chewed　up　in　a　fight　with　another　dog。　Perhaps　it　was　old　or　sick。　But　apparendy'　for　once；　the　swarm　of　rats　had　been　too　much　even　for　the　ratter。　Ish　saw　only　a　few　of　the　larger　bones；　4he　rest　had　apparently　either　been　gnawed　to　pieces　or　dragged　away。　In　the　vicinity；　he　saw　also　the　skulls　of　several　rats；　indicating　that　the　terrier　had　gone　down　fighting。　He　tried　to　imagine　the　scene。　The　swarrning　gray　bodies　clambering　all　over　the　struggling　dog；　the　dog　unable　to　attack　those　which　hung　to　its　back。　Others　must　have　slashed　at　the　hamstrings　like　wolves　attacking　an　old　bison…bull。　Though　the　dog　might　kill　a　dozen　or　fifty；　in　the　end　the　mad；　hunger…frenzied　rodents　must　have　gnawed　through　the　skin　and　tendons　until　the　dog　collapsed。　Ish　drove　away　from　the　spot　feeling　definitely　sober；　and　deciding　that　they　must　keep　an　even　more　careful　watch　on　Princess。　
　　He　remembered；　hopefully；　that　the　ants　had　vanished　almost　overnight；　and　he　kept　expecting　that　something　like　that　also　might　happen　to　the　rats。　But　ther
