Calico – cheap cotton cloth printed in a figure pattern of bright colors, as the dictionary says – was a renowned product of the Cocheco Millworks in Dover, New Hampshire.
The city was not alone. Throughout New England, red-brick mills clustered around rivers seemingly anywhere a dam could be constructed – sometimes leading to factory compounds more than a mile long, like those at Lawrence, Lowell, and Manchester (itself famed for its denim, which gave rise to San Francisco-based Levi Strauss).
Sometimes, the operation would be much smaller, supporting little more than a village.
Upstream, existing ponds were enlarged to guarantee sufficient water flow through the year. Altogether, their commerce left its imprint on the landscape and its character while financing the legacy of the Boston Brahmins.
Likewise, the rain and snowfall flow through many of my poems. It’s not just water over the dam on the Cocheco River, after all, that’s noticed.

I like how this complements the poem you posted earlier and deepens my appreciation of it. Thank you!
