MR. BIXBY: I think so, and without introducing the crystalline element.
Prof. H. H. Hume of Glen St. Mary, Florida was then asked to speak. He said that he uses fresh pine gum from the turpentine cups to make grafting wax stick. This will mix with beeswax and give the elasticity needed for winter work (in the South). Also it is unaffected by a temperature as high as 120 degrees. He uses a mixture of high grade rosin, beeswax and pine gum with which pieces of cloth are saturated. Gum should be obtained in the spring when it is purest. It is thin enough to pour out.
Dr. Zimmerman said that he had tried pine gum with paraffine and it would not mix.
Prof. Hume said that beeswax can be had in various shades up to pure white.
Dr. Morris said that black grafting wax attracts heat and excludes actinic rays. He prefers a translucent wax.
Prof. Hume stated that in the country where Jacksonville, Florida, is there are 100 miles of roadway under construction which will be planted with nut trees where possible. He added that once when he was ill for a long time the doctor finally ordered a glassful of milk and a handful of pecan kernels for his diet. He tried it and it worked.
Dr. Zimmerman said that for grafting wax he had used equal parts of paraffin, stearic acid and beeswax with good results.
Dr. Morris stated his belief that the simple splice graft is the strongest kind.
