Canned Rhubarb (without sugar)

Rhubarb, 2½ lbs.
Water,1 tablespoon

Adelaide washed and wiped each stalk thoroughly, then cut it into small pieces. These she put in the saucepan with a tablespoon of cold water to keep from burning, and stirred with a wooden spoon. She let the fruit heat very gradually and boiled slowly for fifteen minutes. It was then ready to can, and Adelaide poured the rhubarb into the sterilized pint jar at once, after which she inserted a silver knife between the jar and the fruit, to let all air bubbles rise to the top and break. Next came the new rubber, which she dipped in boiling water, placed over the top smoothly, then sealed quickly. Standing the jar upside down she stood it out of the way of any draft. In the morning Adelaide examined the jar carefully to be sure that it did not leak, wiped off the outside with a damp cloth, pasted on the label and stored the jar away in the preserve closet.
