This article begins by tracing the experiments and technology that went into the development of various methods of pipelines and tubing systems for moving maple sap from trees to boiling areas in the sugarbush. The majority of the article focuses on the efforts of three men who were working simultaneously during the 1950s to make a plastic tubing system for sap gathering a reality. These men were George Breen of Jamaica, Vermont; Nelson Griggs of Montpelier, Vermont; and Robert Lamb of Liverpool, New York.
Because space for images and photographs in the published article was limited, I was only able to include a few photographs of Breen, Griggs, and Lamb. With this website, I am happy to share a few more images that accompany the article and better illustrate their efforts, experimental designs, and the resulting commercial products of these creative men.
George Breen
George Breen was a sugarmaker from Jamaica, Vermont who decided that there must be a better way to gather sap than laboriously hauling pails of sap through the snow. This led him in 1953 to begin to experiment with flexible plastic tubing to use gravity and the natural pressure in trees to move sap from the tree to a collection point. In time, Breen’s experiments caught the attention of the 3M Corporation and together they created, patented, and marketed the Mapleflo sap gathering system. Here are a few photos of Breen at work in his sugarbush working with his early tubing design.

Nelson Griggs
Nelson Griggs was an engineer with an interest in maple sugaring and an idea that plastic tubing might be a viable alternative and improved method of gathering maple sap in the sugarbush. In 1955, while working as a engineering consultant with the Bureau of Industrial Research at Norwich University, in Northfield, Vermont, Griggs partnered with the University of Vermont’s maple research team to put his flexible plastic tubing ideas to the test in the sugarbush of the Proctor Maple Research Farm. The following are some photos related to that research.

Robert Lamb
Bob Lamb was in the chainsaw and boat motor sales and repair business in the Syracuse, New York region, mostly working with the logging and marine industry when in 1955 he was asked by a sales contact in forestry business if he could help come up with an idea for moving maple sap using tubing. Lamb put his creative mind to work and developed and marketed his Lamb Sap Gathering System, later named the Naturalflow Tubing System. The following are images related to the early years of Bob Lamb’s tubing design.
