The need of hardier varieties of raspberries for the prairie Northwest is well known. Briefly stated, in an immense region ranging from Wisconsin westward to the Rocky Mountains, north of the line passing through northern Illinois, Iowa and Nebraska, our present standard varieties of raspberries· must, for the best results, be laid down and covered with earth for winter protection. From the farmer's standpoint, at least, this is expensive and unsatisfactory. The following photographs will give an idea of the work in raspberry-breeding at this Station which was undertaken in order to meet this great need.
