Very well, we shall see. My own small experiment in unorthodox ways has the temerity to suggest a new treatment for a species of timber tree which I personally regard as America's very best gift of its kind to the world. For 17 years my modified forest-type planting of black walnut trees has not disappointed me. That is why I now believe that the farmer in the Eastern black walnut's native habitat who fails to set out these nut trees wherever he can is losing a good opportunity.
The McKinster Persian Walnut
P. E. MACHOVINA, Columbus, Ohio
The McKinster Persian walnut first attracted public attention when it received first place in the preliminary Persian walnut contest conducted by the Northern Nut Growers Association in 1949. In the follow-up contest of 1950, the variety was granted third place. The McKinster tree resulted from Crath Carpathian seed secured through the Wisconsin Horticultural Society by Mr. Ray McKinster of Columbus, Ohio. The seed was obtained and planted in the spring of 1938, hence the tree is now 15 years of age. Probably this seed was secured by Rev. Crath during his last trip when, presumably, he made some of his most careful selections.
Altogether, Mr. McKinster planted eleven Crath nuts in the back yard of his small city lot, nine of which germinated. All but two of the resulting seedlings were distributed to friends and relatives living in the countryside. Many of these trees have disappeared due to accidents and lack of care; a few, however, have produced nuts which apparently are not exceptional. One such nut examined was of medium size with a fairly thick shell; the kernel was of good flavor but somewhat bitter. Of the two trees retained by Mr. McKinster, both were permitted to grow where the seed was planted, however one died of an unknown cause when five years of age. Nuts produced by this tree were inferior to those produced by the survivor which later became known as the McKinster variety.

The McKinster tree may be viewed in the accompanying illustrations which show it without foliage and with foliage. The pictures were taken in March and August, respectively, 1953. Since it is a very beautiful and relatively clean tree, the McKinster would be desirable in any yard. From the pictures, it will be noted that the site is unfortunate being restricted by two garages, an alley, and with numerous overhead utility wires. Some effort was made two years ago to keep the tree out of the wires by cutting back top growth. The trimming stimulated the usual vigorous, annual growth to produce terminals as great as 10 feet in one year. Ordinarily, annual growths of 6 feet of husky wood are not unusual. New wood and buds are hardy in appearance and assume a rich brown color upon maturing. With such growth, cutting 1000 feet of scion wood annually would be no problem. The tree is now about 35 feet in height with a like spread.
The bearing record of the McKinster Persian has been excellent. Its first crop of five or six nuts was borne at five years of age and large crops have been consistently set each year since with but one exception. Crop records have been impossible to maintain since the tree is located in a section of the city where squirrels abound. Any nuts saved must be protected by screen-wire cages. The hunger of the squirrels for the nuts is amazing. For example, in 1951, they descended upon the tree during the first week of July and destroyed all nuts of the large crop within two weeks. These nuts could not possibly have been filled and, consequently, could have been of little nutrient value. In their voracity, the squirrels frequently work on the cages and sometimes manage to break through. To facilitate this endeavor, limbs up to one inch in diameter carrying cages are sometimes cut off so the squirrels can attack more conveniently from the ground.
