This grower was not alone in his failure to detect evidence of winter injury as was subsequently proven by the negative replies to a general inquiry to growers in many sections sent out in May, together with numerous reports of severe injury received during June and early July. The fact is that winter injury was more or less general in the pecan orchards of much of the South. Had it been possible to observe further, it is highly probable that a direct relation would have been found between this damage and the lightness in the set of the crop of nuts in 1924 over the general pecan district. Other instances of damages to nut trees which have largely escaped notice might be cited, but these will perhaps be sufficient to call similar cases to the minds of other observers. Of particular interest in the northern part of the country are specific instances of the behavior of individual species and their varieties with reference to ability to withstand local climatic conditions. To cite a few: Mr. E. A. Riehl, of Godfrey, Ill., 8 miles from Alton, reports that during his 60 years of residence on a high bluff overlooking the Mississippi, the pecan trees in the river bottoms of the immediate neighborhood have fruited with exceeding irregularity. A correspondent from Evansville, who cleared 200 acres of forest land along the Ohio of all growth other than pecan, reports that the yields have been disappointing. F. W. McReynolds of Washington, D. C. has 50 or more grafted trees now 8 or 10 years old, 10 miles north of the District, which, although in otherwise thrifty condition, have not fruited. T. P. Littlepage of Washington, D. C., has some 30 acres of pecan trees, also grafted, on his farm near Bowie, Md., which have borne some nuts during the last three years, but the product has been undersized, poorly-filled and distinctly inferior. Mr. Littlepage reports that during the past spring, these trees suffered appreciable injury in the freezing back of the fruit spurs and that the nuts which formed were from a second set of spurs. His trees bore in the neighborhood of a bushel of nuts which looked more promising than usual until the middle of October when freezing temperature occurring between the 14th and the 24th, completely destroyed the crop. At Bell Station, near Glenndale, Md., about three miles nearer Washington than Bowie, at Marietta, a colonial plantation, there is a clump of pecan trees dating back to the days of Thomas Jefferson. These are apparently hardy except in the matter of yields. Dr. M. B. Waite, of the Bureau of Plant Industry, who has long known these trees, states that they bore heavily in one year, about 1912, but that since that time, they have borne very little.
