Mr. Stoke: I fed them to the chickens. Some said that they would keep the chickens from laying but I found that by mixing about 25% with ordinary mash it worked fine.

Mr. Hershey: Did you find that it made the egg shells hard?

Mr. Stoke: No, the chickens had too much sense.

Question: What percent do you lose in sieving?

Mr. Stoke: When I did my fine sieving, I used a 4-inch screen. The shells were taken out entirely. I lost, maybe, 4%.

Prof. Reed: Do you people in Virginia have local names for different types of walnuts? What is the swamp black walnut?

Mr. Stoke: My own opinion is that there is only one black walnut in the East. We have a butternut that some people call the English walnut and some the white walnut. The Japanese walnut is sometimes called an English walnut. We also have the English or Persian walnut.

Prof. Reed: I believe the botanists recognize only the one black walnut.

Prof. Slate: I do not think there is more than one kind.

Mr. Stoke: It is interesting to know that while the black walnut has been higher in price than the English walnut, so that manufacturers have been substituting the English walnut for the black walnut, this year the black walnut has dropped as much as 10c per pound under the English and is now about 5c, I believe. Consequently the black walnut has come into its own and is now being substituted for the English walnut.

Mr. Frey: I would like to mention alternate years in bearing. If apple trees can be made to give a fair crop each year by good care, feeding and spraying, it is my thought that walnut trees will do the same thing under the same conditions. But we must remember that forming the hard shell is a most difficult thing for a tree to do.

Prof. Neilson: I should like to draw your attention to a drawing sent me by J. U. Gellatly. (The paper was held up for all to see.) Just look at the size of the leaves. That is a tracing of the leaf of a hybrid English walnut and heartnut. He sent it along as evidence of its vigor of growth. This large compound hybrid leaf measured 27 inches from tip of the leaf to the bottom of the last leaflet, exclusive of the stem which was 5 inches long. Many of the larger leaflets measured 5 × 9 inches, shape, oblong ovate, edges of leaf, serrate, total width of compound leaf, 17 inches.

Dr. Smith: I should like to suggest to Mr. Frey that the theory he suggested might be supported if the tree were placed in a particularly favorable location.

Mr. Hershey: I should like to remind the audience of Judge Potter who told me some years ago that on his farm in Southern Illinois he got three doubles of his meadow grove of about 50 hickory trees, by using plenty of good horse manure, phosphoric acid, and potash. The increases were that he doubled the amount of growth and the size of the nut and changed the trees from alternate bearing to yearly bearing.
