The subject for experiment then, for members of this audience, is that of finding some substance that may be added to give elasticity, but which will not change the melting point. In the South we may require in addition something to whiten our paraffin. Some men in Southern California wrote me that they had fastened white paper about each graft and put a rubber band over it. I suggested this plan to one or two men in Australia and in Ceylon, who had complained about the melting of the Parowax, and I have not yet received their replies. I have been trying, however, to simplify things in the way of grafting. In addition to the elasticity that we need, we must have whitening, and for this purpose we must add something that will not be poisonous to the tree but will mix with the paraffin readily and give a white paraffin, which will interfere somewhat with the actinic light. I have found that carbonate of lead will mix well with paraffin. Carbonate of zinc will also mix well. They are both heavy, so heavy that they need a certain amount of stirring. A lighter substance is citrate of zinc, which will give elasticity, and which will probably also give a white effect. It melts with the paraffin and, being neutral, it will do no harm to the tree. I have given you an outline on which I wish discussion, for I hope to get from this audience the information and suggestions that will enable me to make my experiments in the right way so that by next spring we may have no further need for discussing the question as to the correct paraffin method in grafting. MR. BIXBY: There is another wax that is not so crystalline as the Parowax, and that is Candelilla, which is produced in Texas and New Mexico. It may be obtained from the wax importers in New York City, not from the Standard Oil Co., but the importers. I will find out just where it is from. I can easily get samples. Its melting point is not so high as Parowax, but it is much higher than any of the other waxes. DR. MORRIS: Then by mixing it with the high-melting point waxes, those of about 138 degrees, we might get good results. 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.
