# The Polar Spring explained — The Adventures of Captain Hatteras > Chapter companion for The Adventures of Captain Hatteras by Jules Verne. ## What happens Dr. Clawbonny persuades Captain Hatteras to allow the use of the American ship Porpoise's wreckage to build a launch for summer exploration, arguing that the glory of reaching the Pole belongs to the expedition's leader regardless of the boat's origin. Altamont agrees to join the expedition and to help build the boat. The chapter then describes the arrival of the polar spring: a sudden thaw, the return of birds and animals, and the brief resurgence of life, followed by a sharp freeze that forces the men to wait for warmer weather. ## Themes in this chapter ### Friendship and Companionship Clawbonny's diplomatic efforts to reconcile Hatteras and Altamont highlight the importance of cooperation for survival and success. ### The Sublime and Dangerous Nature The sudden transition from spring thaw to a severe freeze, along with the return of predators like wolves and foxes, underscores the harsh and unpredictable Arctic environment. ### Human Endurance and Survival The crew's adaptation to extreme temperature swings, hunting for fresh food, and repairing their shelter demonstrate their resilience. ## Character check-ins ### John Hatteras Reluctantly agrees to use the American wreck for a launch after Clawbonny's persuasion, but remains suspicious and hostile toward Altamont. ### Dr. Clawbonny Acts as mediator, convincing Hatteras to accept Altamont's help and the use of the Porpoise's wood; also observes the natural signs of spring. ### Altamont Agrees to join the summer expedition and to build a boat from the wreck of the Porpoise, showing willingness to cooperate. ### Johnson Regrets the burned skins but remains cheerful; helps repair the house after the bear attack and keeps the dogs safe from wolves. ### Bell Tasked with building the launch; experiences the sudden freeze when he steps outside. ## Key lines > You want to reach the North Pole,” resumed the doctor; “I understand your ambition, I share it, but to reach this end we need the means.” “Well, haven’t I so far sacrificed everything in order to succeed?” “No, Hatteras, you have not sacrificed your personal prejudices, and at this moment I see that you are ready to refuse the indispensable means of reaching the Pole.” Clawbonny tells Hatteras that his refusal to use Altamont's wreck is a prejudice that jeopardizes reaching the Pole. _Clawbonny appeals to Hatteras's ambition to overcome his national pride._ > The prisoners were set free; they expressed their joy by the warmth of their thanks to the doctor. The men freed from the bear attack thanked Clawbonny warmly. _Refers to the rescue of the crew trapped by bears in the previous chapter._ > Oh, this polar climate!” cried the doctor, a little disappointed; “that’s the way it goes! Well, I shall have to begin sowing again.” Clawbonny laments the sudden freeze that ruined his newly planted garden. _Shows the doctor's philosophical acceptance of Arctic weather extremes._ ## Links - HTML: https://www.betterreads.online/discover/the_adventures_of_captain_hatteras_se/chapters/xiv-the-polar-spring - Book: https://www.betterreads.online/discover/the_adventures_of_captain_hatteras_se - All chapters: https://www.betterreads.online/discover/the_adventures_of_captain_hatteras_se/chapters
