Looking back on the whole adventure (now twenty years ago) it would be only fair that I mention the names of three other men for the work they did to make the expedition a success. The late Professor James Neilson whose research in nut growing in Ontario and the United States was already well known should be mentioned. It was he who really "sparked" the expedition. To the late George H. Corsan whose nut growing experiment at Echo Valley was something unique in Ontario, credit is due for his enthusiasm and support of the late Reverend Crath. The American nut growers who were fortunate to obtain walnut seeds at the time through Wisconsin Horticultural Society can thank Mr. H. J. Rhamlow, then secretary. He took over the task of distributing the walnut seeds through the affiliated societies. He insisted that the seeds be tested for germination, kept in proper storage, and did everything possible to ensure success. However none of these men as I knew them then, and including myself, would want any credit, but we give full recognition to Reverend Crath for his work. During the years spent in Poland Reverend Crath must have given the idea of growing hardy walnuts in Ontario and the Northern States considerable thought. He examined trees and nuts wherever he went; and continued gathering information each year. When I first met him I could see he had given walnut growing a great deal of study. He had great faith in his idea, and when leaving on his expedition 1934 he felt he was on a great mission. It should be remembered he made this arduous trip without pay and that he made very little money from the sale of walnut seeds or trees. No one did for that matter. It is also significant that in bringing these Carpathian walnuts out of Poland at that time, 1934, he did something that could never be done again. The trees he saw then probably went into rifle butts for use in World War II. The introduction of these walnuts into Ontario, met with varied success. Many bought them on a trial basis and were eventually rewarded; some looked on with skepticism and ridicule and a few thought that the growing of walnuts in Ontario was impossible. The intervening years, however, have brought forth a different picture. These seedling walnut trees are now bearing in Ontario and as late Reverend Crath predicted more than half of them are producing fair to good quality nuts. This is also true in the United States. In Ontario they grow well in the commercial apple districts and with variations mature nuts fully in 90 to 120 days (between Sept. 15 to October 15.) All of the best varieties should now be propagated by grafting to produce hundreds of hardy Crath Carpathian walnut trees. This project should always be one of the foremost with the members of the Northern Nut Growers Association. Twenty years from now and later, the number of hardy walnut trees producing nuts (Crath strain) should make a living monument to this obscure missionary--Rev. Paul C. Crath.
