Trees are reported in twenty-five different counties. Erie County reported, likely, the two largest plantings. Here we have two seedling groves, at least one is a seedling grove. The seedling grove is fourteen years old and contains 250 trees. They are seedling Pomeroy trees and this year show their first real crop of nuts.
Since they are seedlings we naturally find all types and variations among the trees. We see a difference in their foliage, habit of growth, shape and size of nuts. The trees show no effects of ever having been winter-killed. The trees have always been farmed so the owner, Mr. E. A. Silkirk of North East, Pa., has been able to receive returns from his land. Grapes and berries have been grown between the trees as intercrops. The trees are planted on the corners of a 50-foot square and cover about fourteen acres.
In four different counties of the mountain section of the state, bearing trees are to be found. From these trees we hope to find something at least fairly good but above that something hardy. Some of these trees have been winter-killed to a more or less degree, but so have the common peach trees in the same sections.
The southeastern part of the state reports the largest number of trees. From Harrisburg east and south the trees become more common. In this section we find Dauphin, Adams, York, Lancaster, Chester, Philadelphia, Bucks, Lebanon, Lehigh and Berks counties. In these counties the Persian walnut is not at all uncommon. They are often called Dutch nuts as well as English walnuts.
Just north of the above section we find Northampton County reporting a large number of trees, and even in the Wilkes-Barre and Scranton section with a higher elevation the nut is growing and yielding good crops.
I asked nearly all walnut tree owners whether or not they thought the business could be developed, and in most cases they believed it possible.
I have come to more or less of the conclusion from what I have been able to see, that the business will not be developed in our so-called mountain land or upon the waste lands. The better soil should be used for the walnut groves.
As time goes on we are going to find more and more groves of the nuts being planted in our state.
I came here to learn rather than to lecture. If I can answer any question I will be glad to do so. Tonight I will gladly show you a few pictures with the lantern.
I might say that the Experiment Station plans to have a small grove in a few years; with this and co-operative work we hope to be able to give to our growers and interested people some idea of the culture and care of the Persian walnut in Pennsylvania.
