The Iowa State College recently blasted eighty-two oak andelm stumps and trees averaging 20 inches in diameter, at an aver-age cost of about 38 cents each for explosives. On a large land clearing operation in Minnesota during thesummer of 1 909, eight thousand, nine hundred and seventy stumpswere blasted out. Although a considerable number of these were.
