1912年，美国爱荷华州曼森，一位工人挖井却挖出了奇怪软水。41年后，经爱荷华大学地理学家实验勘察异样的岩石，断定该地区软水和独特的岩石层系古老而又不明确的火山活动所致。这一结论符合当时的学识水平，但只可惜它是不对的。

The water was odd too. It was almost as soft as rainwater. [---2---]

Though Manson’s strange rocks and silken waters were matters of curiosity, 41 years would pass before a team from the University of Iowa got around to making a trip to the community, [---3---] In 1953, after sinking a series of experimental bores, university geologists agreed that the site was indeed anomalous and attributed the deformed rocks to some ancient, unspecified volcanic action.
