DR. MORRIS: I have tried many but the one I use the most is the commonest one. You can buy parawax in all groceries. If you wish to make the parawax harder for the southern sun put in stearic acid. It may be bought at any drugstore. Melt it with the paraffin and that will harden it very much.
QUESTION: What proportion do you use?
DR. MORRIS: It would depend on the degree of heat to be resisted. I suppose you might use it in the proportion of one to four of parawax, but very little stearic acid will harden it.
QUESTION: Isn't there a tendency to melt under the high temperature of the sun?
DR. MORRIS: As a matter of fact I pay no attention to that in the North. Although we have very hot days and the paraffin does soften, it does not seem to interfere with the repair on the part of the tree.
QUESTION: In the case of smaller grafts, what would be your objection to the use of the ordinary whip graft?
DR. MORRIS: It makes one more motion.
QUESTION: It seems to me that it is more quickly done?
DR. MORRIS: It may be; that is a matter of individual technic. My idea is to do the thing the quickest way. If a man has found that he can put on one graft more quickly, that he has a technic that gives him speed, which is one of the essentials of grafting, if you can put on the whip graft quicker than I can put the other on, do it.
QUESTION: Do you have any trouble with the oxidizing of the cambium?
