After the scoring was complete the ice was cut in one direction by a horse drawn ice saw. The ice was then cut in the opposite direction following the scored lines but only cut about two thirds of the way through resulting in long chains of ice, which were gradually moved in open water canals to the ice house for storage.
As the ice chains neared the ice house the final cut was made with a hand held ice saw to form blocks approximately 34 inches by 22 inches. The ice was moved into the ice house by a steam driven endless chain "elevator" fired by a steam boiler. The entrance to the elevator was under water, and the ice blocks were poled on to the elevator.
When the ice got to the top of the elevator the blocks were moved along gravity fed ramps to their final storage location. The ice was insulated by sawdust between the individual blocks and the layers. When the ice house was full, it was insulated by salt hay and additional sawdust and sealed with boards on the exterior to protect the ice from the weather. Companies generally harvested at least one-third more ice than they anticipated selling because of losses due to melting during storage and shipping.
 In mid-March when the need for ice began, the ice was gradually transferred into barges using the same endless chains in reverse order. The summer crew was much smaller than the winter harvesting crew as fewer people were needed to move the ice into the flat-bottomed barges. Also, farmers who worked in the winter were no longer available to work in the summer months. The holds of the barges could carry from 400 to 1,100 tons of ice. The family of the barge owner lived in the engine house on the deck of the barge. While not shown in this photograph, later barges had windmills on the top of them to provide power to pump out water from the hold as the ice melted. A tug boat would haul a line of barges down the river to the New York City area for distribution.
Once the barges reached their destination they were unloaded by derricks to over 700 ice dealers who backed up their wagons to receive the ice for distribution to their local customers. This early newspaper advertisement extolled the merits of the ice wagons for sale. The last line in the lower left of the advertisement is somewhat amusing. Brakes for the ice wagons were optional for an additional ten dollars!
After the development of artificial ice in the 1920s and refrigeration in 1932, the demand for river ice dropped off dramatically. The ice harvesting declined very rapidly during this time until it ceased all together. Some of the massive ice houses were later used as mushroom "factories" for a few years, but most of the ice houses were taken down, or they fell into decline and later burned until there was no visible sign left of this once thriving Hudson Valley business.
An excellent series of newspaper articles on the ice industry was written in 1983 by Alice Walsh, former Castleton Village Historian. These articles provided much more detail than provided here and included names of local people involved in the ice industry and their recollections. Copies of the articles are available in the Town of Schodack Historian's office.
