Editor,  Rose Mermaid.
Since the introduction of this Rose last year, many doubts have been expressed as to the hardiness of this charming variety.
I think this feeling was largely due to the fact that one of its parents was the Macartney Rose, and that numbers of stocks that were budded last year, from some reason or other, failed. I must confess that I too, had my doubts, but they were entirely dispelled one fine morning in September, when visiting Messrs. Wm. Paul and Son's Nurseries at Waltham Cross, accompanied by Mr. Samuel McGredy, of Portadown.
Mr. Arthur Paul very kindly conducted us round the extensive nursery, where we saw many of the firm's new seedlings, making one especial note, by the way, of a new bicoloured Rose named Toreador. Unexpectedly we came upon a large breadth of cutbacks of Mermaid, and what a sight it was! The sun had only recently broken through the autumn mist, and the beautiful shining foliage was still wet with dew. There were blooms by the thousand, enormous ones, too, many being five or six inches across. We stood admiring them for some considerable time, when suddenly Mr. McGredy turned to Mr. Paul and said, " I have seen the sight of my life, it's simply magnificent. I would not have missed it on any account." Surely a very graceful tribute from one raiser to another! Mr. A. Paul very kindly gave me a few notes of the history of this handsome addition to the single flowered Roses. This variety was obtained from a species that has hitherto been seldom hybridised, flowers of Rosa bracteata (the single white Macartney Rose) having been fertilised with the pollen of a double yellow Tea Rose. He told me that about a dozen seedlings were obtained, most of which produced single pale yellow flowers which varied in size and regularity of petals, although two or three of the progeny gave double blossoms. The former were tested side by side and Mermaid was selected as being the finest, both for its colour and the unusual size of its flowers and also for the beauty of its foliage, the bright glossy green of its large leaves and the ruddy tinge of the young shoots contrasting beautifully with the pale waxen sulphur-yellow tint of the petals, the effect of the latter being heightened by large clusters of amber coloured stamens. It also differs from Rosa bracteata in its longer season of flowering, its: more vigorous growth and its hardiness, plants standing quite unprotected in the open ground at Waltham Cross having withstood 28 and 29 degrees of frost last winter, which was one of the wettest on record for the Lea Valley, without sustaining any injury, which was clearly proved by the plants we saw. In the Rose garden it will prove most valuable for climbing and for forming large single bushes and clumps, as it throws up strong shoots from the base 6 to 8 feet long in a season, whilst as an ornamental shrub. it will be unique, and to my mind the best way to grow it, producing its huge star-like blossoms (often measuring four to five inches in diameter) continuously from early in July until stopped by frost in the autumn. Visitors to the Drill Hall have seen the fine stands exhibited throughout the year, and it has received a Gold Medal from the National Rose Society and has also been awarded the Cory Сup.  
The double flowered seedlings which resulted from the same cross were found to produce milk-white blossoms of good size and substance, opening well, together with handsome bronzy foliage, and the flowers are also produced over a longer period than those of Rosa bracteata. The best of them has been propagated and placed in commerce under the name of "Seafoam," a handsome variety with small double milk-white flowers, very striking, which received  an Award of Merit from the Royal exhibited last summer.
