Edgar Hastings, a Pennsylvania farmer, is sealed in his snowbound cabin in 1835 and preserved asleep until 2135. A descendant guides him through a reformed America, and he measures each change against the drunkenness, filthy streets, and legal subjection of wives he remembers.
The book argues that when married women gained legal control of their own property and earnings, other reforms followed. A wife who is no longer economically captive can refuse a drunkard or a wastrel. Men then have to reform their conduct to keep a household, so temperance and moral improvement come from changed incentives rather than from preaching.
The reformed future treats clean streets, pure water, and orderly public works as moral institutions, not just amenities. Removing filth and disorder from the shared environment lowers disease and degraded habits together. How people behave in public follows from the conditions the city physically provides.
Moving an ordinary man from the present into a reformed future turns the present's accepted customs into things that need explaining. What 1835 took as natural, such as a husband owning his wife's wages or drunkenness as part of daily life, looks arbitrary once a future exists without it. The outsider's surprise works as an argument that current arrangements are choices, not necessities.
