The first grafting of black walnuts thus comes down to the beginning of
the 20th century.
William P. Corsa[3] with the USDA gave much information from replies to
a questionnaire sent out in 1890, on nut culture and grafting, including
bench grafting, in 1896. Mr. G. W. Oliver[13] in 1901, describes a
method followed by Corsa in bench grafting walnuts and hickories. He
used an incubator. Mr. Jackson Dawson[15] previously, working with
hickories, had success in the greenhouse.
Andrew S. Fuller[4] in his Nut Culturist, published in 1896, advises
that the South had not yet perfected pecan grafting. This seems to have
been a challenge to Mr. J. F. Jones[1 & 7], for we find he moved from
Missouri to Monticello, Fla., about 1899, and specialized in pecan
grafting. He developed the slanting cut he later advocated in walnut
grafting. However, again showing "there is nothing new under the sun"
the author's uncle, Owen Albright, is credited by Corsa[3] with
suggesting it in 1894, and it is also suggested by Mortillet[11] in
1863.
