I have given last year cuttings of following Northland-roses to the Society's Garden in Sangerhausen: Freya, Griseldis, Siwa, Wachhilde. These are not Elite-Roses, but still well double, vigorous, repeating richly until winter, and good seed-bearers, therefore quite sufficient for breeding of new varieties. Let us hope that they will find acclaim. Karpona, 18. February 1910, Rudolf Geschwind
