The Japanese walnuts generally grow fast but usually do not attain a large size. In most cases the trees rarely grow more than 35 feet tall with a spread of 30 to 50 feet, but occasionally specimens attain much larger size. The writer saw a heartnut tree on Mr. Kratz's farm near Jordan Station, Ontario, which had a trunk diameter of 2 ft., a height of 35 ft., and a spread of 64 ft. Near St. Thomas, Ontario, there is a large sieboldiana tree which is 75 ft. across the top and is about 45 ft. tall. Mr. Ricks reports a huge tree near Olney, Pennsylvania, that is 80 ft. across the top and 60 ft. tall and Dr. Deming reports a tree with a spread of 100 ft. _Varieties_ Through the efforts of the Northern Nut Growers Association members several good varieties have been found and propagated. These varieties have been widely distributed but have not been extensively planted. The results are variable as might be expected, but generally the reports are satisfactory. In the eastern states the following varieties seem to do reasonably well: Faust, Bates, Ritchie and Stranger. In British Columbia, Messrs. J. U. and David Gellatly have located several very good strains such as Gellatly, O. K., Calendar, Walters and Rosefield. These newer varieties from the West have several good characters and are worthy of a wider trial in the East. _Diseases and Insect Pests_ In common with most other forms of plant life the trees are susceptible to some insects and diseases. Reports of injury by the walnut weevil, Conotrachelus juglandis, and also by codling moth larvae have been received. In some cases the foliage is attacked by rust fungi and some injury is also done by leaf spot. Prof. Reed reports witches broom attacking some trees in the South and one case of this disease was observed by the writer in Ontario on a Siebold-butternut hybrid. Notwithstanding these defects it is believed that the Japanese walnut is less attacked by disease and insects than most other species of nut trees. _Opinion of Observers_ The opinion of a group of people on the merits or defects of a tree species or project is worthy of consideration. In order to get an expression of opinion as to the merits of the Japanese walnut the following question was asked: Do you consider the better strains of Japanese walnut worthy of more extended planting? The answers to this inquiry were numerous and varied. The great majority were in favor of increased plantings but a few were somewhat dubious. Nearly every one agreed that the species possessed marked beauty and was worthy of more extended planting as an ornamental. Some gave preference to the nuts over the black and English but the majority thought the quality was not quite up to the standard of these two species. Some observers reported favorably on the heartnut for culinary purposes and as an ingredient of ice cream and candy. With these latter comments I have had personal experience and can heartily agree. _Summary_
