Mr. McCoy: I have no set speech to make I thought maybe there were some things I might say to be a help to some of you; some things that would have been lots of help to me a year or two ago from some one, because nut trees are more difficult than any other nursery stock to propagate, and for another reason it is more difficult in the North than in the South. Mr. Paul White and Mr. Ford Wilkinson have both worked in the North and in the South, and after coming back home these boys say that anybody can propagate pecans in the South, but with us it is different. We have kept at it, though, and our president has been our good friend and has always helped us out. There have been three of us incessantly at the work. Mr. Littlepage would come down home and get us together and ginger us up, and we would go back and go to work and try again. It has been one continuous line of failures, but every year we have learned some things, or at least learned how not to do it. This spring we were fortunate in having an expert from the South who came to my nursery and stayed there until midsummer, and we saw our own work compared with his. We all had great respect for him and he is able, too. I don't think he had much respect for us when he got here but he had a whole lot when he went away for he made a miserable failure like the rest of us. Mr. Jones, you know, is an authority on grafting. He is the man that introduced it to the nut world, at least in the East. I think it had been tried in California before. We have tried his methods and everything else that government experts or any other expert told us about, and we have read all the magazines that were published from the South to the North. Everything seemed to be a failure and finally I got disgusted and said "We will do it to suit ourselves." After we had tried all the hard ways in Christendom I think we have at last found an easy way to do it. Like everything else it is easy when you know how. I believe it is a fact—and I am saying nothing but what I believe—I don't believe you will ever successfully graft pecan trees in the North, unless you equalize your sap flow by pruning your roots. I tried it and failed. It is possible you may be able to side graft under most favorable conditions. You may make a side graft take if you leave the top on to take care of the extra sap flow. You take off the top of a pecan tree, or any other nut tree in this country, and you ruin your root system because your sap comes with such vengeance—and it comes! One day there is no show of sap and the next day it comes with vengeance. Differences in the soil, of course, makes some difference. At Mr. Littlepage's place, Paul had the sap a week before I did and Mr. Wilkinson had it four days before. A great many of our top works are going to the bad because we ruined the root system when we cut the tree. And I want to say it again, I don't believe we can make a success of it in the North. You may do it in Oregon where you have a distributed sap flow. The Oregon fellows say you can't bud, because they don't know how. They say the only way you can produce trees is to graft. That may be true out there but you can't graft in Indiana, I know, especially on my place. Of course the soil of each particular farm has something to do with it. To illustrate my point, the first year I was in the state of Wisconsin, on the 20th of June, I was out in the country and saw a man setting tobacco. I knew him and I said, "Won't that tobacco get frost bit?" and he said, "I reckon not. It might but it never did." I thought it would, but I went that way in two weeks again and I changed my mind. I had been used to seeing tobacco growing in the Ohio valley where it does its growing in the latter part of the season. In the South the sap flow is much better distributed than it is in the North.
Now, then, I have brought a board along with these young trees stuck in it, because I thought some of the members would like to see a demonstration. The tools I have here are not adequate, hardly, for the job. For a tree that size we take a saw to it.
(Here Mr. McCoy makes a demonstration of cleft grafting.)
Mr. Potter: Would you have a scion as long as that in actual work?
Mr. McCoy: Many of them are, but it would be better smaller, probably. That is a matter I don't think there is much to, whether the scion has one bud or ten. I think three is perhaps about right.
Mr. Potter: They come together right there?
Mr. McCoy: Exactly on the front side. Now you understand this grafting is done when the sap is flowing, or about the time the sap flow begins. Usually at our latitude here you will commence grafting anywhere from the 6th of April to about that time in May. Of course when you are cutting trees at that time you have got an immense flow of sap. Mr. Jones tried this method without drainage, that is the way they do out in Louisiana, but he only got ten per cent to stick, so we had to work out a drainage for ourselves. Take a piece of heavy wrapping paper, rather good quality such as you can get at any paper store, and put it right over your graft, and a little bit below the cut on your stock. Then simply take a piece of raffia and wrap. Then make the ordinary tie that anyone knows how to make with the cotton or twine, or sometimes with the raffia, and you have the drainage of this paper. The tie, of course, is simply to re-enforce the strain on the graft and hold it. Then you apply the grafting wax. The one we use is three of resin, one of beeswax, and lampblack and a little bit of linseed oil. Cover up the graft entirely, except don't cover over the lower end of this paper because there is the drainage where the sap flows out. Then you put an ordinary paper sack right over it, and leave it on for about three weeks.
A Member: You don't tie the paper below the raffia?
Mr. McCoy: That does not make any difference.
A Member: At what time do you cut a hole in the bag to give it air, or do you do that?
