description- – Image of Holyoke?s wooden dam, the first successful structure to harness the Connecticut River for its power-generating potential. Built in 1849, it was replaced by the current stone dam in 1900. In the foreground the water of the Connecticut River cascades over the dam creating hydroelectric power for the city of Holyoke. To the right of the dam is a view of Howard Street, located in the Highlands neighborhood of Holyoke. In the background is a misty view of Mount Tom.

description- – Image of two men standing in a penstock. Penstocks are used to convey water under pressure from the collecting pool underneath a dam to the turbines used to power factories. The men are in the process of repairing the grate designed to regulate the flow of water through the penstock. Both men hold hammers. They are standing on a frame of wood. The walls of the penstock surround them showing the large rivets fastening the large metal plates. A pile of wood can be seen in the foreground.
