Day 356 – For local tribes around Lake Titicaca in Peru and Bolivia, cattails, or Typha, were among the most important plants and every part of the plant had multiple uses. For example, they were used to construct rafts and other boats. During World War II, the United States Navy used the down of Typha as a substitute for kapok in life vests and aviation jackets. Tests showed that even after 100 hours of submersion the buoyancy was still effective. Typha are used as thermal insulation in buildings as an organic alternative to conventional insulating materials such as glass wool or stone wool.
Day 357 – Cattail or Typha stems and leaves can be used to make paper. It is strong with a heavy texture and it is hard to bleach, so it is not suitable for industrial production of graphical paper. In 1853, considerable amounts of cattail paper were produced in New York, due to a shortage of raw materials. In 1948, French scientists tested methods for annual harvesting of the leaves. Because of the high cost these methods where abandoned and no further research was done. Today Typha is used to make decorative paper.
Day 358 – Cattails or Typha can be used as a source of starch to produce ethanol. Because of their high productivity in northern latitudes, Typha are considered to be a bioenergy crop.
Day 359 – The seed hairs of Cattails, as known as Typha, were used by some Native American groups as tinder for starting fires. Some tribes also used Typha down to line moccasins, and for bedding, diapers, baby powder, and cradleboards. One Native American word for Typha meant "fruit for papoose's bed". Typha down is still used in some areas to stuff clothing items and pillows.
Day 360 – Cattails can be dipped in wax or fat and then lit as a candle, the stem serving as a wick. Without the use of wax or fat it will smolder slowly, somewhat like incense, and may repel insects.
