As ice is usually sold on the pond for one dollar per ton, an ice pond will be found an excellent investment in any dairy country. All that is required is a clear running stream, with low banks bordered by flat bottom land. A dam may be thrown across the stream to back the water up to the higher ground on each side. The dam must be built upon sound principles, or it will not retain the water. The bottom must rest on solid fresh ground, free from stone, grass, or decaying.

A trench three feet wide is dug out on the line of the dam down to solid ground, clay, or hard pan. Stakes are then driven in the middle of the trench reach- ing as high as the top of the intended dam, and tongued and grooved or otherwise tightly-fitted planks are nailed to these stakes. Solid earth is then packed and puddled in the trench on both sides of the planks, and the dam is then raised to the hight desired over this foundation (figure 60). The slope of the dam should be such as to make a six-foot dam nine feet wide at the bottom on the inside and six feet wide on the outside, or fifteen feet in all. This slope is needed to prevent leakage and the washing down of the soil. The earth for the dam may be dug out of the intended Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Stewart, Henry.
