Now I am going to use the plane on a little larger scion. That is about the slope that I would use ordinarily. We will say this is to be the scion and this the stock. In order to make them fit perfectly I will use a smaller block plane. Now I will pass this about. You see with what absolute perfection those surfaces fit. You can get absolute perfection of fit by trimming a scion with a plane instead of with a knife. Even the best experts, like Mr. Jones, who make beautiful free-hand cuts, will find that with a plane they may make still better ones. That is one of the grafts that I would ordinarily fasten just with raffia, but I will fasten one together with screws to show how it is done. Now we will say that this is the stock and this is the scion. I am going to prepare them to fit each other. Some will ask if I ever use a scion as large as that. Sometimes I use a scion two or three feet long and as large as that in diameter. They are full of vitality and make wonderful growth. In order to do this I trim it down roughly with the knife to the general shape before I use the plane. I will cut as true as possible with the knife in order to simplify my work later.
MR. WEBER: In a large scion don't you have to have a larger exposed surface?
DR. MORRIS: I do not think that really counts.
MR. SMEDLEY: Isn't the tree in the ground when you graft it?
DR. MORRIS: This is supposed to be in the ground.
MR. JONES: You couldn't do a thousand of those a day?
DR. MORRIS: If you have something special, where you want to use up some big scions. But you can use the plane on little grafts just as well. Now this is the stock and Dr. Deming is going to represent Mother Earth.
MR. SMEDLEY: Are the scion and stock necessarily of the same diameter?
DR. MORRIS: Not necessarily, but preferably so. One's sense of nicety might demand that they be just alike, but you will find it doesn't make any difference. It takes a little longer to put in a big scion of his sort but it is very sure to grow. Your tree is already made by the time you have done this.
MR. SMEDLEY: Should you have bark contact all around?
