originated in Michigan alone (largely as a result of the work of Prof.
James A. Neilson of East Lansing) to preclude any obvious need, at
present at least, of bringing varieties from farther south into this
zone. In addition to these, a number of other varieties have been
recognized from equal latitudes, as in New York and, west of Lake
Michigan, in Wisconsin, southeastern Minnesota and northern Iowa.

ADAMS--The Adams black walnut is a rather small variety with an
approximate size range of from 34 to 48 nuts per pound, and an average
of 39. In a cracking test of the 1930 crop, conducted after the kernels
had become too dry for most satisfactory cracking, the yield of quarters
was 16.75 per cent; that of small pieces 7.81 per cent, and the total
24.56 per cent. The nuts are much elongated in form, being sharply
pointed at each end. Many are quite symmetrical, thin-shelled and, when
not too dry, of excellent cracking quality. The kernels examined have
been notably bright in color, firm in texture, very sweet and highly
pleasing to the palate. The quarters are long and slender.

The Adams was first called to public attention in 1920, when the late
Henry Adams of Scotts, Kalamazoo County, Michigan, was awarded first
prize for an entry of nuts from the original tree which he made in a
contest held that year by the Northern Nut Growers Association. In an
article published in the Michigan farmer of Detroit, on July 7, 1922, he
stated that this tree grew as a sprout in a corn row on land which he
cleared in the spring of 1869. When the tree was seen by the writer in
1929, and again in 1932, it gave the impression of having been a
moderate or slow grower. Such facts as have been obtainable from time to
time indicate that it is but a moderate bearer. However, the character
of the soil in which it stands is not of the best, although it is far
from being poor. In better soil it would doubtless produce heavier and
more uniform crops.

As nearly as it can be ascertained, the Adams was first propagated by
the late W. G. Bixby of Baldwin, Long Island, who procured scions in
1922. It was again grafted six years later by J. F. Wilkinson of
Rockport, Ind., with scions procured by the U. S. Department of
Agriculture. In April, 1930, one of the resulting trees was shipped by
the Department to the Kellogg Experimental and Demonstration Farm,
Augusta, Mich. Trees are now growing on the grounds of the United States
Department of Agr
