In a letter written to Secretary Hatton on August 16, 1939, Mr. Horvath, who had in the meantime looked up his old records, wrote thus:

"It was not in New Jersey where I was employed by the firm of Pitcher & Manda (also known as United States Nurseries) but after leaving P. & M., from where I went to Newport, R. I., that the birth of the Wichuraiana hybrids occurred. It was while I was absent from Newport, leaving my plants in charge of V. Vanicek, a friend of W. A. Manda, that the original hybrid plants were given to him, thus finding their way into commerce. Corrections may now be made, because I have found the record of the missing pollinate parent of the two pink hybrids. R. Wichuraiana X Agrippina gave two crosses, including Pink Roamer and South Orange Perfection. Two others, Manda's Triumph and Universal Favorite, resulted from crossing R. Wichuraiana X Paquerette, a small imbricate-petaled dwarf white Polyantha.
