PROF. MANEY: Oh, the temperature was up to 100, 103 and 104. MR. WEBER: What kind of paraffin did you use? PROF. MANEY: Just ordinary paraffin. MR. WEBER: Did you notice any bad results? PROF. MANEY: No, apparently no ill effects. MR. WEBER: Paraffin has a tendency when it gets extremely hot to run down and kill the graft. DR. SMITH: What would be the effect of putting in some beeswax? PROF. MANEY: I think that would be all right. MR. WEBER: Paraffin this summer killed two nut grafts for me. DR. ZIMMERMAN: Are you sure it was the paraffin? I have finally come to the conclusion that when the sun gets hot enough to melt the wax it will kill the graft anyway. MR. WEBER: I noticed the heat did not kill another one that I did not use the paraffin on. Previous years it simply scorched the tree. DR. ZIMMERMAN: The heavy coating of wax protects a little from the heat, I thought. MR. HARRINGTON: In very hot weather I put heavy paper around the graft and a handful of dirt. That protects it from the sun. MR. WEBER: I have tried that. THE PRESIDENT: I am very much interested in seeing Professor Maney's spraying apparatus. We also tried to spray and got something like snow. We also found that the wax congealed in the nozzle. Last spring I almost blew my head off. I am now experimenting with a material which acts as an emulsifying agent on waxes and resin. I have developed a formula, paraffin 5 pounds and Pick Up Gum one pound. I dissolve the emulsifying agent and heat the wax. This solution can be sprayed on trees without difficulty when it is warm. When it gets cool, however, we have to heat it again. I hope to have some definite reports to make as to the feasibility of this later on, and possibly on conifers as well. We have been up a tree when it came to spraying wax and we have been at a disadvantage in transplanting conifers. Regarding the comments as to paraffin wax melting, I do have a little difficulty on the south side and sloping to the northeast. The sun's rays would be rather direct. I think the suggestion Mr. Weber made was very good. Two-thirds paraffin and one-third beeswax. Possibly we would have to increase the beeswax where trees are growing on a southern slope. DR. ZIMMERMAN: I found the hottest place 2 inches above the soil. I shade grafts with a piece of shingle. THE PRESIDENT: The principle in grafting trees is to regulate the moisture and the temperature factors. As a means of regulating the moisture I use German peat around the graft. MR. HERSHEY: Have any of you had experience in grafting on the north side of the stock? I found that quite a good scheme, so that the heat doesn't kill the grafts. We grafted on the 15th of June this year.
