duction of Persian walnuts. Select two varieties whose characteristics you desire to blend and that will pollenize each other, and grow seedlings from the resulting nuts. You can check results in as little as four years by taking buds from the seedlings at two years and placing then on black walnut. Creative work, this. You will get the thrill of your life--if you are that kind of a person--and may produce something well worth while. Persian walnuts are self-pollenizing if pistillate and staminate blossoms occur at the same time, but such usually is not the case. Crath, Breslau, Caesar and King produce their pistillate blossoms some days before their staminate blossoms shed their pollen, while Payne, Lancaster, Broadview, Franquette and Mayette produce their blossoms in reverse order. Of all those I have tested only Bedford can be depended to produce both types of bloom simultaneously and certainly and fully pollenize itself. It is enlightening to keep a record of the blossoming time of each variety relative to others, but dates should all be recorded for the same year. Warm, early spring induces early blooming; late, cool weather delays blossoming. By my records, Payne pistillates were receptive May 3 in 1935, April 28 in 1937 and March 31, in 1945, a variation of over a month. All varieties vary with the season, but the variation is greatest with the early varieties. There has been little disease among my Persian walnuts except that in wet seasons leaves and nut shucks are sometimes attacked by a fungous blight. In the city there has been no insect injury worthy of note. In the country, adjacent to wooded areas, insect injury is sometimes serious. Pests include spittle bugs, stink bugs and other insects that attack young leaves and tender growth. These check the leaders and cause late multiple growths that may fail to mature and hence winterkill. In such locations the butternut curculio also attacks and destroys the young nuts. Avoid wooded areas if choosing a site for a Persian walnut orchard. The most destructive pest with which I have had to contend has been the large black-bird or purple grackle. Oddly enough they are much worse in the city than in the country. As soon as the young are grown, about the middle of June, they appear in flocks and attack the nuts of the Persian walnut. At first, before the shell has hardened, they penetrate the nut apparently for the nectar which is the substance of the i
