entire surface of the granules are wet put mch and pentane into a liquid mixer vessel and stir for 15 minutes or until homogeneous put the dimer acid polyamide beads in a solids mixer equipped with a spray impregnation apparatus and begin mixing spray the solution of mch into the granules while mixing when the entire solution has been transferred stop the solids mixer and inspect visually for uniform wetness of the granules if the solid is not uniformly wet continue spraying pentane not containing mch until uniform wetting is achieved blend for 5 minutes apply a slight vacuum and remove pentane while continuing the blending operation all of the formulations should be packaged in fiber drums with heavy polyethylene bag liners as various changes could be made in the above compositions without departing from the scope of the invention it is intended that all matter contained in the above description shall be interpreted as illustrative and not in a limiting sense the concentration of mch need not be limited to 2 percent the field test was conducted during 1975 in meadow creek drainage 6 miles southwest of elk river clearwater county idaho elevation was 3 000 feet above sea level tree species in the test area were douglas fir pseudotsuga menziesii var glauca biessn franco grand fir abies grandis dougl lindl western larch larix occidentalis nutt and western white pine pinus monticola dougl in order of abundance thirty live dominant douglas fir trees averaging 24 inches diameter at breast height 129 feet height and 103 years age were felled 21 22 april treatments were applied 9 may a few days prior to first douglas fir.
