The Run a Cape Cod Naturalist Experiences the Beauties and the Dangers of the Cycles of the Migrating Alewife

Sublime and enchanting is how John Hay has the reader feeling. It is truly a superb book, well written and thoughtful as well as thought provoking.

I first read this book in the early 1970s when I was conducting my Ph.D. thesis research, which dealt with the migratory behavior of a fish called the alewife, also known as river herring. Alewife are like small, silvery salmon. About 10 inches long, they migrate into small streams and rivers along the East Coast in the spring to spawn, and the juveniles then migrate to the ocean in the fall, where they live for four or five years before returning to their home stream to spawn. John Hay captures the mystery and delight of an alewife run. Unlike salmon runs that occur in large rivers where the fish can't be seen, alwife migrate into many very small streams, many of which pass through towns and under old mills, such that the fish are readily visible to people. To see thousands of fish stacked up at the base of a dam, knowning that they had traveled thousands of miles in the Atlantic for years before finding their way back to the location where their life began as an egg, is almost incredible. John Hay describes the essence of the alewife in a very informative but tremendously readable style. This is a must read for anyon who enjoys fine writing and has an interest in the natural world.
