Charlotte was visiting Chebeague Island, one of two hundred islands in Casco Bay, 10 miles northeast of Portland.

Since the late 19th century, the area was a popular spot for people of New England who wanted to embrace more simple or rustic living during the summer.

Chebeague can be reached only by boat or ferry – there is no bridge to the mainland.

Charlotte was staying at the Hamilton Hotel, but dozens of summer camps remain on the island today.

On July 27, Charlotte sent a postcard to her friend, Mrs. Amos Miller, who lived in Camp Hill, PA.

Charlotte wrote that, “you and Amos should have been here yesterday”, a very large tuna was caught and brought ashore.

The weather has been chilly; Charlotte notes, “we haven’t had any real warm weather since I’ve been here”.

The face of the postcard is a beautiful illustration of the lighthouse at Portland Head.

In the 19th century, Maine industries of fishing, boat-building, and whaling, depended upon safe navigation and safe harbors.

The Portland Head Light is the oldest lighthouse in Maine, completed in 1791.

The State of Maine has 65 lighthouses.

One hopes that Charlotte continued to enjoy the sights of Chebeague and the Mrs. Miller was pleased to receive the lovely postcard.
