ponyat', kak, ne primenyaya tolstyh derevyannyh katkov i prochnyh kanatov, mozhno bylo peredvigat' i ustanavlivat' podobnye glyby. U ostrovityan ne bylo ni koles, ni tyaglovogo skota i nikakogo drugogo istochnika energii, krome sobstvennyh muskulov. Udivitel'no i to, chto v 1770 g. statui eshche stoyali, no v 1864 g. vse oni okazalis' oprokinutymi samimi ostrovityanami. Zachem oni vysekali ih v kar'ere? Pochemu oni prekratili eto zanyatie? Obshchestvo, sozdavavshee statui, dolzhno bylo sushchestvenno otlichat'sya ot teh 2000 chelovek, kotoryh videl Roggeven. Ono dolzhno bylo byt' horosho organizovano. CHto s nim proizoshlo?
