Aside from the pecan there are no named Pomological varieties of any native nut now being propagated, with very few exceptions. So far as these exceptions are concerned, it is probable that fewer than one hundred budded or grafted trees of such varieties are yet of bearing age, and of such as have attained the age at which fruit might be expected, exceedingly few have borne in paying quantities for any number of consecutive years. Therefore, with reference to the planting of native nut species for profit, the truth of the situation is simply this: In the ordinary course of events, with the exception of the pecan, years of experimentation in the testing of varieties and in a study of their cultural requirements must be gone through before any native species of nut-bearing trees can be planted in any of the northern states with a certainty of commercial return from nuts alone which would be comparable with that of many other crops which already are upon a well established commercial basis in this part of the country.
With reference to two of the foreign species of nuts which have been introduced, the situation is quite different. In order of commercial importance of the nuts now grown in this country, two foreign species, the Persian (English) walnut and the almond, stand second and third, respectively, the pecan, which is an American species only, being first. With these exceptions, the foreign introductions are all in the experimental or test stage, and while possibly the European hazel (filbert) may now be making a strong bid for commercial recognition in the northwest, and the pistache in parts of California, neither species can yet be recommended for commercial planting.
With the exception of a few hardshell varieties of almonds, which are practically as hardy as the peach and which are suitable only for home planting, as they are in no way to be compared with the almond of commerce, there is now no indication that this species is destined ever to be come of commercial importance east of the Rocky Mountains.
The Persian or so-called English walnut is of commercial importance in this county only in the far Western States. In the South, it has thus far failed altogether. In the North and East it has held out gleams of hope, first bright, then dull, for more than a century. There is no way of telling the number of trees of this species which have been planted in the northeastern section of the country, but let us imagine it to have been sixty thousand. Of these fully fifty per cent have succumbed to climatic conditions; twenty-five per cent have been but semi-hardy, and possibly twenty-five per cent have attained the bearing age. A part of each of the last two classes have borne crops of commercial size for a number of years. Some have produced nuts of good size and quality. A great many of all those surviving are now proving susceptible to a walnut blight upon which Mr. McMurran is to report tomorrow. A liberal estimate of the present number of bearing Persian walnut trees in this part of the country would be ten per cent of the original supposed sixty thousand or six thousand trees. Of these, the writer has positive knowledge of none which are now bearing crops of nuts in such quantity, and of such size, and quality and with such regularity and which have so borne for such length of time as to encourage commercial planting. Few of the eastern grown nuts are so free from tannin as to be really pleasing to the taste, or favorably comparable with the best nuts of the market. The writer is now closely watching the best known varieties which the nurserymen are putting out, but at the present time there is no variety which, in his judgment, should be commercially planted without further testing.
