John Craig of Cornell University, Dr. Robert T. Morris, Dr. W. C.
Deming, Mr. T. P. Littlepage and others. Craig had previously been at
Iowa State College where he and Budd had shown much interest in nut
trees.

In 1912, Mr. J. F. Jones [1][7], came up from the South where he had
been successful in pecan grafting and started a black walnut nursery at
Lancaster, Penna. He had been in Florida up to 1907. While in Florida he
became acquainted with Mr. John G. Rush, of Willow Run, Penna., and did
some walnut grafting for him. It was Mr. Rush who advised him to go to
Lancaster and start a nursery for northern black walnuts. Jones patented
his patch budder in 1912, and using the hot wax method developed by Mr.
E. A. Riehl was very successful in walnut grafting.

In 1914, Dr. W. C. Deming and President T. P. Littlepage of the N.N.G.A.
and Messrs. C. A. Reed and C. P. Close of the USDA had a conference in
Washington which resulted in the publication of the American Nut
Journal.

Paraffin In Grafting

Dr. Robert T. Morris[10], writing in the American Nut Journal in 1929,
advocates the use of paraffin to cover walnut grafts instead of wax.
Both he and Dr. J. Russell Smith[15] credit Mr. J. Ford Wilkinson with
first using paraffin instead of wax on walnut grafts. Mr. Wilkinson
wrote that he got the idea from seeing a careless workman splash
paraffin on the buds as well as on the union in fruit tree grafting at
the McCoy Nursery about 1914. The author bought apple and plum grafts
about 1922 from the Gurney Nursery which were all covered with paraffin.
It was at conventions of the Northern Nut Growers' Association that new
methods like this were passed along to members.

Bench Grafting

In 1932, on account of the difficulties in outdoor grafting of the
walnut, the author became interested in bench grafting of walnuts in the
greenhouse as a means of supplementing outdoor grafting. However, like
many other so-called new methods, it was discovered when we looked up
the literature in 1937 that William P. Corsa[3] had used methods that
were similar about 1896. He cut off the seedling above the crown instead
of below the crown as we did. The completed graft was packed in layers
of sphagnum and placed in an incubator instead of using a greenhouse.

Notwithstanding all that has been done in black walnut grafting, the
straight grained and brittle wood, the heavy sap flow, the almost
instant oxidation of cut tissues, the liabilit
