loojv, but it soon recovers its beauty and 

 fruits finely. 



Next comes R. alba, of doubtful origin 

 but of unusual beauty. Tile bush is 

 covered with single pure white dowers, 

 eaeb two and one-half inches in diameter 

 and borne in clusters, the stamens form- 

 ing a dense mass an inch broad, yellow 

 at first, but turning brown later on. It 

 requires protection with me. Paul's 

 Carmine Pillar rose when in full flower is 

 worth a long journey to see It is not 

 over hardy and in protecting it tor its 

 winter's rest I prefer to lay it down, 

 covering the branches with evergreen 

 boughs and a water proof box. Its sin- 

 gle carmine flowers arc three inches in 

 diameter and freely produced. Caul's 

 Single White, a bush form, rather dwarf. 

 has paper-white flowers p oduced quite 

 freely, and very closely resembles the 

 white form of R luciila. I protect it 

 slightly. Cooling's Single Bedder prom- 

 ises well. I know nothing of its parent- 

 age or hardiness. Its flowers are much 

 like those of Paul's Carmine Pdlar, being 

 of the same size, but the plant is very 

 dwarf. 



Classed among the single roses may be 

 placed the hybrid sweetbriars, the grand- 

 est acquisitions our gardens have been 

 favored with for years. 01 the seven 

 varieties grown here 1 am the most im- 

 pressed with Meg Merrilees in its rampant 

 growth and large rich crimson flowers. 

 All of these hybrids possess the leaf fra- 

 grance of the sweetbriar to some degree 

 and are fairly hardy. A. Wichuraiana the 

 Japanese trailing rose whose habit, when 

 established, of sending out prostrate 

 shoots ten to twenty feet long, enables it 

 to be trained to posts, arches, or arbors 

 with effect. The clusters of large pure 

 white flowers in July followed by bright 

 persistent fruits, both well set off by the 

 dark green, glossy leafage, evergreen 

 under some conditions, are very decora- 

 tive. Manda's hybrids of this are well 

 worth growing. It is hard to decide 

 which is the best. Those who like any 

 color so long as it is red, will prefer the 

 Pink Koamer, which is perhaps the best 

 for trellis work as it is the strongest 

 grower. It is supposed to have sweet- 

 briar blood in it as the flowers somewhat 

 resemble that species, but thev are of a 

 much brighter pink than the general run 

 of briars we see. 



Universal Favorite is less vigorous, 

 bears light pink double flowers, two 

 inches in diameter, somewhat fragrant. 

 Manda's Triumph is a still more moder- 

 ate grower but extremely floriferous. The 

 flowers are wtiite, very double, imbri- 

 cated, and sweet scented. They are a 

 little less than two inches in diameter 

 and very much like an enlarged bloom of 

 the polyantba rose White Pet. All of 

 these hybrids possess beautiful glossy 

 foliage a little larger than that of R. 

 Wichuraiana. I have not grown South 

 ( Irange Perfection. Mr. Jackson I fawson 

 has hybrids of A'. Wichuraiana not yet 

 introduced to the general public that 

 possess unusual merit. W. C. Egan. 



ROSES AT THE ARNOLD ARBORETUM. 



Hybrid roses are not reliably hardy in 

 the United .States. True, there are sonic 

 localities where they succeed tolerably 

 well, but in most places their culture is 

 continued under discouraging conditions. 

 A large number of plants never get strong 

 enough to bloom well and those that do 

 are short lived. The question of estab- 

 lishing or creating a new breed better 

 suited to our climate has engaged the 

 attention of specialists for a long time. 



SPRAY OF NEW ROSE EVERGREEN GEM 



Among others Mr. Jackson Dawson, of 

 the Arnold Arboretum, Boston, has given 

 much time and thought to the subject. 

 At first he believed it was a question of- 

 stock for grafting, and he has experi- 

 mented largely with native and other 

 reliably hardy species. A'. multiBora has 

 been tried with most satisfactory results, 

 so far as concerns vigor. At fust stem 

 grafting was practiced, but this has 

 proved unsatisfactory on account of suck- 

 ers; roots alone are nowused. Someeves 

 of Paul's Carmine Pillar on roots have 

 grown four feet this season. Florists 

 complain that tea roses are too rank on 

 the niultillora stock and that the flowers 

 are Soft. So much for stocks. 



The idea that hybrid roses could be 

 made hardy by grafting on a hardystock 

 has been abandoned. Mr. Dawson now 

 considers a new type necessary. This he 

 is working for, and showing what cross 

 breeding and selection will do, we need 

 only look at Mr. Manda's hybrids and 

 Mr. Dawson's with A'. Wichuraiana. In 

 choosing A'. Wichuraiana and General 

 Jacqueminot, two very distinct roses are 

 brought together. Only an innate love 

 for experiment could suggest such a 

 proceeding. Some curious breaks, and 

 some valuable ones, havecome from these 

 crosses. The indications are plain that 

 by following them up, infusing hybrid 

 blood, and reverting occasionally for
