It covered an acre of ground well north of 125th Street, rising a modest fifteen stories, its foundation secure in that layer of rock which mimics eternity. It deserved its name: here men had brought samples of everything, literally everything known in the course of humanity since prehistory. It was, within human limits, definitive. In its way, considering how much the erosion of time must always steal from scholars, it was perfect. * * * * * No one had felt anything unnatural in the refusal of the Directors of the Museum to move the collection after the Museum weathered the storm of 2057. Instead, ordinary people, more than a thousand of them, donated money so that a mighty abutment could be built around the ground floor, a new entrance designed on the north side of the second. The abutment survived the greater tornado of 2064 without damage, although, during those seven years, the sea had risen another eight feet in its old ever-new game of making monkeys out of the wise. It was left for Brian Van Anda alone, in 2079, to see the waters slide quietly over the abutment, opening the lower regions for the use of fishes and the more secret water-dwellers who like shelter and privacy. In the '90s, Brian suspected the presence of an octopus or two in the vast vague territory which had once been parking lot, heating plant, storage space, air-raid shelter, etc. He couldn't prove it; it just seemed like a comfortable place for an octopus. In 2070, plans were under consideration for building a new causeway to the Museum from the still expanding city in the north. In 2070, also, the final War began and ended. When Brian Van Anda came down the river late in 2071, a refugee from certain unfamiliar types of savagery, the Museum was empty of the living. He had spent many days in exhaustive exploration of the building. He did that systematically, toiling at last up to the Directors' meeting room on the top floor. There he observed how they must have been holding a conference at the very time when a new gas was tried out over New York in the north, in a final effort to persuade the Western Federation that Man is the servant of the state and that the end justifies the means. Too bad, Brian sometimes thought, that he would never know exactly what happened to the Asian Empire. In the little paratroop-invaded area called the Soviet of North America, from which Brian had fled in '71, the official doctrine was that the Asian Empire had won the war and that the saviors of humanity would be flying in any day to take over. Brian had doubted this out loud, and then stolen a boat and got away safely at night. Up in the meeting room, Brian had seen how that new neurotoxin had been no respecter of persons. An easy death, though--no pain. He observed also how some things survive. The Museum, for instance, was virtually unharmed. * * * * *
