Sacramento City was one place by day and another by night; and of the two, its night side was the most peculiar…the canvas house, lighted from within, shone with a broad, obscure gleam that confused the eye and made the streets most familiar by daylight look strangely different …the town, regular as it was, became a bewildering labyrinth of half-light and deep darkness, and the perils of traversing it were greatly increased by the mire and frequent pools left by the rain.
