Foreword

This volume is going to press somewhat later than was anticipated, and in order to expedite its publication, a few papers which were contributed in 1951 are being held over for the 1952 Report. Two of these will incorporate new data to be presented at the 1952 meeting, Mr. E. A. Curl's discussion on the status of the oak wilt disease and Mr. W. W. Magill's talk on top working of native pecans in southwestern Kentucky. Also deferred are Mr. L. Walter Sherman's "Final Selections in the Five-Year Ohio Black Walnut Contest", the vice-presidents' round table discussion led by Mr. H. F. Stoke, on "What Black Walnut Varieties Shall We Recommend for Planting?" and two short papers from the Ohio section.

"Bunch Disease of Black Walnut" by Drs. McKay and Crane in this volume was read at the 1950 Pleasant Valley Meeting, and the discussion on it will be found in last year's Report. Other "Extras" are the propagation papers by Mr H. P. Burgart and Mr. Gilbert L. Smith, Dr. J. Russell Smith's and Mr Carl Weschcke's papers on pecans, and the reprinted article on Colby Persian walnut by the secretary. (The original tree has a big crop of nuts now maturing.)
