Mr. Pomeroy: The husks turn black?
Professor Close: Yes.
Mr. Pomeroy: That is not blight; that is a fly injury
Professor Close: Mr. Killen thinks that this year he partially controlled walnut blight with Bordeaux spray. One particular tree stands near where the spray tank was filled and one side of it was sprayed every time the spray rig passed it. The nuts from the sprayed side were really better than those from the other side.
Just below Dover, Delaware, at Woodside, I was at Mr. Sam Derby's place last Saturday and found something very valuable in the line of Persian walnuts, I think one of the best I have seen at all in the East. One particular tree was purchased for a Franquette but it is not. It probably is a Mayette seedling. Some of the men who tested the samples think this was one of the most desirable they had seen in the East. Mr. Derby bought about a dozen trees eight or nine years ago from some nurseryman. The trees are not alike in shape and size of nuts. They evidently are from the same bunch of seedlings but were sold for Franquette and Mayette. They are probably all Mayette seedlings.
Now, coming back to College Park, four years ago Mr. Littlepage was good enough to give me some pecan scions which I grafted into a seedling tree in a neighbor's chicken yard. The grafts practically all lived and last year, three years from the graft, about a dozen Major nuts were produced. These are probably the first Major pecans produced in Maryland. This year the Busseron and Major grafts bloomed but we had so many late frosts that the blossoms were killed and now there are only two Major nuts on the tree. My own trees are not old enough to bloom except one Mantura which bloomed this year but did not set fruit. I presume it was largely due to the late frosts.
In the fall of 1910 Professor Lake gave me some buds of Persian walnut and I put three buds into a young black walnut tree. During the following February we had a drop in temperature to 25 below zero, something almost unknown in this section of the country, but two of the buds lived through it. After growth started in the spring I cut one out and the other grew into a tree which produced three nuts in 1915. My area for nut trees is small so I am planting pecans, black and Persian walnuts, and hickory twenty feet apart with the idea of keeping them pruned. I have ten varieties of pecans and several of walnuts. Between these I have chinkapins and hazelnuts. There are eight or ten varieties of hazels and about sixty seedlings for grafting later on.
Mr. Littlepage: Did the young pecan trees bloom.
Professor Close: Only the Mantura and it must be about ten years old.
Mr. Littlepage: What kind of bloom?
