(35) Two rows of many species of nut trees planted in thick glazed earthenware pots. The pots are about four feet in depth and with round perforations. I had these made to order. I sunk them in the ground to the level of the rim and then planted these trees in the pots under the impression that they would remain dwarfed on account of the confinement of the roots, and that I would have a conveniently placed series for experiments in hybridization. The experiment was not a success. I knew that growing trees would move rocks, but had no idea that roots protruding through these holes in heavy glazed earthenware would be able to break the pots. The roots have done just that, and whenever a tree in a pot becomes large enough the protruding roots break the pot to pieces, and the tree marches straight along to its original destiny. (36) One of a group of European chestnuts from seed brought me by Major L. L. Seaman. The parent tree is famous in England for its enormous size and heavy bearing; it is said to be centuries of age and is growing upon the estate of Sir George B. Hingley, Droitwich, Worcestershire, England. My young trees are growing very thriftily. They are showing some blight spots, but this has been controlled by cutting out and painting. (37) A group of vigorous young trees, the result of placing pecan pollen on the pistillate trees of Siebold walnut. They show the Siebold parentage so distinctly that I imagine them to be parthenogens, but we cannot tell to a certainty until they bear fruit. (38) A hillside set out with a large number of common bush chinkapins from the East, tree chinkapins from Missouri and a number of hybrids. The chinkapins and the alder-leaved chestnuts on this side hill have been so blight resistant as to require almost no attention, and for that reason I am making hybrids between the chinkapin and the alder-leaved chestnut and the Chinese chestnut in the hope of making an excellent combination of chinkapin quality and Chinese size. Up to the present time none of my hybrids have been as valuable as either parent, with the exception of two. Two of the hybrids bear nuts about the size of the average American sweet chestnut and of first rate quality. These two hybrid trees have shown no sign of blight as yet.
