Whitney Floyd, extension forester for-ester at Utah State Agriculture, college recommends since the ui tree constitutes a very serious fire hazard. This hazard increases proportionately propor-tionately with the length of time the tree is kept. A freshly cut tree does not ignite easily because of the moisture content.but the moisture soon evaporates and the tree becomes dry. This drying lowers the kindling point temperature temper-ature and the tree catches fire easily, a fact that is even more true in the case of evergreen trees because they contain resinous substances sub-stances that easily ignite, Professor Profes-sor Floyd states. While the inexpensive methods he recommends will not completely complete-ly fireproof the Christmas trees they will, if followed carefully, greatly reduce their fire hazard. To fireproof a Christmas tree use a soulUon of ammonium sulfate sul-fate sinos it is cheap, effective, and easily obtained. To make the solution so-lution (1) use one-fourth pound ammonium sulfate for each pound the tree weighs. (2) Place the ammonium am-monium sulfate in a glass jar, tin pail, or earthen crock and dissolve dis-solve in water, using VA pints of water for each pound of ammonium ammon-ium sulfate. A narrow-mouth container con-tainer is preferable as it lessens evaporation of the solution. (3) Just before terating, saw off the stem of the tree about an inch from the end, preferably at an oblique angle or in a V shape, |
