This spray gun is now sold by two manufacturers. It is estimated that between 5 and 10 percent of gum- producing trees are now treated with acid. Three years ago only a small fraction of one percent was treated. The satisfactory spray gun will be an important factor in further increasing this percentage.

Chipping and Dipping Offer Best Possibility for Mechanization A survey of the time and cost of woods operations revealed that dipping and chipping present the best possibilities for mechanization. These two jobs require walking 3>000 miles per crop per season, a distance equal to a walk across the United States. Biweekly or triweekly chipping, made possible by acid stimulation, reduces this to 1,800 or 1,4-25 miles, respectively. A bulletin covering this research is being published by the University of Approximate distribution of gum production costs for large operators, as of 1946. - IS -.
