Short History

Prior to European settle colonization, Indigenous peoples likely used the resources on the island seasonally for thousands of years. In the 1600s, the island was granted to Elder Brewster of Plimouth Colony. Later, Charles Apthorp owned the island, as well as other property in the Harbor, including Long Island. In 1789, the Massachusetts Humane Society constructed a "hut of refuge" here.

James Turner (who later became the keeper of Bug Light at the western end of Brewster Spit) owned the island in 1845, he and built his home from two deckhouses that washed ashore from the wrecked steamer Ontario. In the same year, a small group of lobster fishermen occupied the island. They built small wooden shelters here. Illegal boxing matches were staged on the island in 1883.

In 1902, Benjamin P. Cheney and his wife, actress Julia Arthur, built a colonial style, two-story summer estate with roofs used to collect rainwater. The last of the estate remains were burned in 1971, and in the 1990s vandals toppled one of two chimneys.

The US Government acquired rights to the island during World War I until the end of World War II.

 

Natural History Overview

Vegetation

The windswept island has a thin layer of soil that supports grasses, shrubs and salt-tolerant trees. A 1903 newspaper article describes the island landscape: "... here are groves of wild cherries, clumps of sumac, precipitous cliffs interspersed with ideal stretches of beach, fringed with wild basaltic rocks. Here is pasturage for two Jerseys, soil enough for a garden, a miniature pond and broad stretches of lawn." Today the island supports wild cherry, beach plum, tall grasses, chives, and mock orange. Further research is needed to document remains from the Cheney's cultivated landscape.
