Not illustrated. 1915 edition. Excerpt: ... in this way the body is kept warm. Food supplies three essential body needs: --1. Building material. 2. Energy or power for play or work. 3. Heat to warm the body. All good foods supply each of these three things. Very few foods contain just the right amount of each The types kind of food material. Some foods, such as of food eggs and meat, contain more building material material. tan jjy nee(js, while others, as butter and sugar, are composed wholly of energy and heatmaking material.

If laid out straight and measured, this canal would be about thirty feet long. more
