This Bulletin may be considered as a continuation of Bulletin 87; The Improvement of the Western Sand Cherry; and Bulletin 88, Breeding Hardy Fruits. The improvement of the native Dakota sand cherry by selection from many thousands of seedlings is still in progress the fruiting of the fourth generation is awaited this year. Some of the best of the third generation are an inch in diameter and of good quality. Several of these have been sent out for preliminary trial but only one has been named, the Sioux. These have been budded on native plum, (PRUNUS AMERICANA) stock, as it furnished a convenient means of propagation and obviated the risk of mixture of sprouts from the seedling stock which would be the case were the budding done on sand cherry stock. The press of other ·work has prevented extended experiments in cheaper methods of propagation, but limited trials show that they can be propagated from cuttings; and layer easily where the branches are covered in nursery row. With a view to securing a tree of greater vigor then the sand cherry so as to make it an orchard fruit, rather than a small fruit, extensive experiments have been carried on for several years in hybridization of the sand cherry with choicer fruits. Some of these have fruited the past two years and it appears desirable to present a brief report at this time. Today, May 28, 1908, under appointment from Hon. James Wilson, Secretary of Agriculture, I start on my third trip to Siberia as agricultural explorer for the United States Department of Agriculture. It will be my fourth trip to Russia.
