G. ROBERTS 247 Ash Street Portland, Oregon Sole Manufacturers: William Cooper & Nephews CHICAGO, ILLINOIS taken up is to find the best pollenizer for the sterile or nearly sterile varieties, such as the Spitzenberg. We have found that a large number of varieties will cross with the Spitzenberg, such as Newtown, Arkansas Black, Jonathan, Baldwin, Ort- ley. Stark, Black Twig, King of Tomp- kins County, York Imperial, Delicious. There were many others, but most of them not of commercial importance in the Northwest. We have been working out whether or not it was feasible to plant Yellow New- towns and Jonathans together to see whether these varieties crossed in any way. Our results show that these can be planted together very nicely. Our next line of work was to take up some self-fertile varieties like the Yellow Newtown and to find if they would be improved by crossing. The first two years we crossed the Yellow Newtown with a large number of varieties, and in both the Hood River district and the Willamette Valley we found the apple was greatly improved by crossing such varieties as Grimes Golden and Ortley. The crossed apples gave a large per- centage of fruit set and also gave a better average size than those self-pollenated with Newtown pollen. The work in the Rogue River Valley seems to show that the Newtown was not as greatly improved by crossing with such varieties as Grimes Golden and Ortley. The last two years, however, we have obtained splendid results not only in the Rogue River Valley but elsewhere by cro
