Mr. Weber: Are these thornless?
Mr. Moore: These are thornless honeylocusts. The original parent trees of the Millwood and Calhoun had thorns. By vegetative propagation—they went out and cut scionwood on the limbs above the thorns and propagated the thornless twigs on thornless root stock—we now have a thornless honeylocust.
There has been quite a bit of disturbance in Alabama, especially in the northern part of the state, caused by native honeylocust. We have two or three characteristics that I think ought to be brought out about honeylocust. Some of out trees in the northern part of the state of Alabama have triple thorns. It is known as G. triacanthos and the "tri-" part of that particular word, of course, gives us an idea of three thorns, and I have seen thorns at least 12 inches long that you could catch in your hand and use for a dagger, and it would be very dangerous. Now, some of those trees growing in the northern part of the state are very serious pests in pastures. Cows and horses and hogs are very fond of those lucious pods, and they will go around the trees and pick up every pod that falls, and occasionally a horse or cow will get close enough to the trunk of the tree and get speared with those thorns, and when the thorn pierces the skin there is a little tip on the end that breaks off and is left inside. When the usual infection that it carries get started from the part of the thorn that is left in the flesh, you get pus and, of course, later on the amputation of the leg, if it happens to be in the leg, of the horse. With the thornless type that is completely eliminated.
Then this other thing that I think ought to be brought out, the thornless or near-thornless type as a general rule has a better quality of pods than the ones with the long thorns. Now, it is true that the parent seedling trees of the Calhoun and the Millwood both had a small quantity of thorns when they were growing wild. After they were propagated vegetatively the thorns, of course, were eliminated by taking scion wood from above the thorns. But in general in our state, the thornless trees—and we do have a lot of thornless trees growing wild—have a higher sugar content in the pods than do the trees with thorns.
I just wanted to give you a general idea of what we have done with honeylocust in Alabama. In 1938 the TVA sent down some Millwood and Calhoun for test planting. We put those trees in two different types of planting. We had an integrated planting where we were trying to select at that time some good pasture plants, and, of course, we had something like a hundred different species in the one planting. The trees were planted relatively thick, but the larger trees were planted longer distances apart, and the intermediate trees intermediate distances apart, and then we had shrubs coming in under those. It was supposed to have been a three-story type of planting, black walnut in the upper story, honeylocust as an intermediate and shrubs for the ground. We were using different types of plums for the understory; then on the ground we had Lespedeza sericea. But from that we did get several different plant materials that did look promising, and we put the Calhoun honeylocust and the Millwood honeylocust in with that planting for trial, and they did so well that we expanded the honeylocust into another planting. I am very sorry that this latter planting had to be taken out.
Hillculture research went under in June of 1947, and the Horticulture Department took this work over, and they thought they could not support the honeylocust pasture program in Horticulture, and the plot, of course, was pulled out and planted in peaches.
Anyway, we do have some information I'd like to give you. The Dairy Department of the Alabama Experiment Station carried out quite an extensive feeding test over a two-year period to find out the value of these pods in the dairy ration. They substituted the honeylocust pods ground. Professor Eaton of the Dairy Department assures me that none of the seeds in those pods were cracked. They ground the pods with corn in order to take up some of the excess honey that is in the back of these pods so that they'd grind well, and they ground them in a hammermill, and the burrs were running far enough apart so that he assures me that very few of the seeds, if any, were ever cracked.
That has been somewhat of a discussion, among feed producers especially, recently, as to whether or not it would be profitable to grind those seeds in order to get the protein and fats that the seed has. There isn't a very high percentage of food in the seed itself, but you do get a little more protein and a little more fat if you grind the seed itself.
We have found in storage that weevils get in these seeds, but the weevil doesn't destroy the carbohydrates, and the weevil will only pierce the seed and make a hole in it. Then the intestinal juices of a cow will go in through this hole and they can digest the seed. That is something that comes along with storage.
I'd like to give you just something briefly on what the Dairy Department of Alabama Polytechnic found out about the general value of these pods. They found that honeylocust pods could be substituted in a dairy ration for oats, pound for pound. Now, that means that if you can get a high yield of honeylocust pods and substitute it in a dairy ration for oats that you just about have half of the grain problem solved.
