MR. SILVIS: Due to the fact I have started to mulch with sawdust I have been using nitrate and rock phosphate, so my teeth don't fall out when I chew them.
MR. SLATE: I crack mine with a hand cracker, I don't crack them with my teeth.
DR. COLBY: Mr. Chairman, we can grow filberts. How does the chairman keep the squirrels from eating them?
MR. STOKE: I will tell you that.
MR. SLATE: Mr. Stoke raises his nut trees in the Sunny South, and he has problems down there that we don't have up north. I think he has to worry a lot more about winter killing than we do way up north where we are in Central New York. What's been your experience with some of the varieties and what are your principal cultural problems with the filberts?
MR. STOKE: I wish to answer Dr. Colby's query about squirrels. I find that squirrels are very highly allergic to these BB caps or the CP caps used in a 22 rifle. It works. In my back yard there is a Brixnut filbert, which originated in Oregon. I guess it's been there 15 years. There are four trunks to it, the largest about 16 inches in diameter. One of those I grafted to Giant, as a pollinizer for Brixnut. It's similar in shape, somewhat smaller in spite of its name, but it's pretty effective. Then about ten years ago there was an old gentleman from Halsey, Oregon. I don't know whether any of you have corresponded with him or not. He bought the Breslau Persian walnut—I pretty nearly said the English walnut, and I'd have been disgraced—and furnished me scions and I got a start of it from him. Russ sent me some scions from a filbert he called Jumbo. You will see it out on the table there. It's rather a long nut, little larger than DuChilly and not quite so flat, that I grafted in there. It absolutely is hopeless as a pollinizer for anything, because it loses its staminate blossoms by Christmas. But the Hall's Giant pollinizes them, and it's the best filbert I have, all things considered. This year off that one scion—of course, it's four inches in diameter—I got about 7 quarts of nuts, and they began ripening at least three weeks ago, and the crop is all off now. And the foliage is unusually heavy, almost in clusters, and it drops cleanly and freely from the husks, and I think it is a very nice filbert. Whether it's a recognized variety in the West I have no idea, and I haven't corresponded with the old gentleman for some years, and he probably has passed on by this time, because he was an elderly man and not in good health at the time I had my correspondence with him. I consider that an excellent filbert, and I think anyone wishing to plant filberts should investigate with the Oregon nurseries or Washington nurseries and see if that is a recognized variety. I tried to find out once and failed so far. I do not have it on its own roots. I hope that I will have it rooted in another year.
In my back yard also I have one that I bought in Oregon. That's as tall as up to that beam, maybe almost to the ceiling, very vigorous growth, larger nut than Longfellow, thicker nuts and also longer. But I think the thing he sold me was a graft and the graft died and this came from the root. It bears very sparingly, but it's a very large nut, and I wondered why it was always so spare, and I caught it blooming in December, staminate blossoms in December this year. So that's that.
Ten miles east of my home, east of the Blue Ridge Mountains in the granitic, very heavy clay soil of what we call the Piedmont down there, I have a planting that was made 15 years ago of filberts, some on their own roots and some that I grew on the Turkish tree hazel stocks. Those grew well, and the main advantage was they put up no suckers. You had a nice clean trunk, and you didn't have that problem of getting rid of the sprouts all the time. And it looked very good for a while.
I find where you graft that way, the stocks get old and do not renew themselves, and eventually the life will be shorter than if you had a shrub that might last for a century, when you are renewing your stalks when they reach maturity and cease to grow enough to be productive.
Two years ago I had most of the standard varieties you mentioned here in that planting, about three-quarters or perhaps an acre planted in between chestnut trees. Planted the chestnut trees 40 feet apart and then interplanted with the filberts at 20 feet. Two years ago we had an unusually wet season, and the blight, of which I had had some before, hit hard and virtually ruined the whole planting. And in addition to that, we have leaf miner. It's an insect that lays a tiny egg in the leaf and develops a little larva or worm that eats out the chlorophyll between the two membranes of the leaf, just hollows it out and makes unsightly spots in there and, of course, kills that portion of the leaf. But the blight, known as the eastern filbert blight, according to Mr. Gravatt, has just ruined that planting. Some of the trees have been killed outright, and most of the tops are either dead or dying. This year the blight wasn't apparently active on the living part, because it was very dry up until the first of August, and since then it's been very wet. That's what happened to my filberts there.
