View of a sawmill on the Penobscot River showing many logs in the water in the foreground. Workers are visible guiding logs from the storage pond up jack ladders into the mill to be processed.
After logs were cut and floated down the Penobscot, they were drawn up short by the boom streched across the river. Here, the logs were identified by the hallmarks cut into them at lumber camps, and separated by owners. In this picture, the ebbing tide has tumbled logs against each other along the bank. The pylons of the boom can be seen in the background in the middle of the river; a chain reached between them to halt the logs.
