“Atanyrate，“saidAlcide，“whateverthedangermaybe，Iknowsomeonewhowillnotland！“

Ataboutteno’clock，however，HarryBlountcaughtsightofanumberofblackobjectsmovingontheiceblocks。
Springingfromonetotheother，theyrapidlyapproached。
“Tartars！“hethought。Andcreepinguptotheoldboatman，hepointedouttohimthesuspiciousobjects。
Theoldmanlookedattentively。“Theyareonlywolves！“saidhe。
“IlikethembetterthanTartars。Butwemustdefendourselves，andwithoutnoise！“
Thefugitiveswouldindeedhavetodefendthemselvesagainsttheseferociousbeasts，whomhungerandcoldhadsentroamingthroughtheprovince。Theyhadsmeltouttheraft，andwouldsoonattackit。
Thefugitivesmuststrugglewithoutusingfirearms，fortheycouldnotnowbefarfromtheTartarposts。Thewomenandchildrenwerecollectedinthemiddleoftheraft，andthemen，somearmedwithpoles，otherswiththeirknives，stoodpreparedtorepulsetheirassailants。
Theydidnotmakeasound，butthehowlsofthewolvesfilledtheair。

Infact，halfanhourafterthecommencementoftheattack，thewolveswerestillcominginhundredsacrosstheice。Theexhaustedfugitivesweregettingweaker。Thefightwasgoingagainstthem。
Atthatmoment，agroupoftenhugewolves，ragingwithhunger，theireyesglowinginthedarknesslikeredcoals，sprangontotheraft。
Jolivetandhiscompanionthrewthemselvesintothemidstofthefiercebeasts，andMichaelwasfindinghiswaytowardsthem，whenasuddenchangetookplace。
Inafewmomentsthewolveshaddesertednotonlytheraft，butalsotheiceontheriver。Alltheblackbodiesdispersed，anditwassooncertainthattheyhadinallhasteregainedtheshore。
Wolves，likeotherbeastsofprey，requiredarknessfortheirproceedings，andatthatmomentabrightlightilluminatedtheentireriver。
Itwastheblazeofanimmensefire。ThewholeofthesmalltownofPoshkavskwasburning。TheTartarswereindeedthere，finishingtheirwork。Fromthispoint，theyoccupiedbothbanksbeyondIrkutsk。Thefugitiveshadbythistimereachedthedangerouspartoftheirvoyage，andtheywerestilltwentymilesfromthecapital。

Theconflagrationwasgoingonwithfrightfulrapidity。

Nevertheless，thefugitives，lightedeverynowandthenbytheglare，wouldhavebeenundoubtedlyperceivedhadnottheincendiariesbeentoomuchoccupiedintheirworkofdestruction。

But，happily，thebreezedidnotblowfromthatside。

Itwasjustpossiblethatthefugitiveswouldescapethisdanger。

Bythistimeitwasnearlymidnight。Thedeepgloomagainthrewitsprotectingshadowsovertheraft。TheTartarswerethere，goingtoandfroneartheriver。Theycouldnotbeseen，buttheycouldbeheard。

“Youhearthem，“saidAlcide。
“Yes，“repliedMichael，“butGodiswithus！“
Thesituationbecamemoreandmoreserious。Shouldtheraftbestopped，notonlywouldthefugitivesnotreachIrkutsk，buttheywouldbeobligedtoleavetheirfloatingplatform，foritwouldbeverysoonsmashedtopiecesintheice。
