New Use for Wheat Straw. The wheat growers of the Central West are a t last about to realize a dream that they never believed would come true. They are to have an outlet for the waste straw that is left over after every harvest. The custom has been for the farmer to apply a lighted match to the straw stacks on some still night, as the easiest and quickest way to get rid of them. Because of the long, tough, fibrous nature of wheat straw it would hardly be eaten by a starving animal. Its low content of nitrogen, phosphorus, and potash made it of negligible value far fertilizing purposes and its resistance to the corroding action of the elements made it a nuisance when the farmer began preparing his land for the next mop. The fact that straw can be converted into insulating board of the highest quality is one of the recent and valuable discoveries of science. Tests have shown that straw as insulating material has a value of more than 10 per cent aver other fibrous g-rowths, such as cornstalks, which were found unsuited for the purpose of good insulation I t also showed remarkable tests for structural strength. The first mill to engage in the manufacture of straw into insulating boards is now building a t St. Joseph, Missouri, and will represent the latest developments in pulp and insulating board equipment. Its proximity to the wheat fields of Kansas, Missouri, Nebraska, and the Dakotas insures a never-failing supply of raw material and give5 to the farmers of this region an outlet for a waste product that will add many dollars to credit a t the bank.
