afterwards. Hand-picking seems the best method of 

 destroying the worms affecting the buds, and frequent 

 drenchings with the hose abolish the other enemies. 

 In the fall the canes are bent down and fastened to the 

 base of their neighbors, and remain procumbent until 

 the spring cutting-in, which is delayed as late as possi- 

 ble in order not to incite too early a start and to force 

 the buds to "break" low down. After the leaves used 

 in the winter protection have been removed, and the 

 board roof also, the sides of the "box" are allowed to 

 remain a short time in order to shield from the winds. 



The winter of 1898-9 was unusually severe and did 

 more damage to the Roses and other material than any 

 other winter which the writer has experienced at 

 Highland Park. Following is a list of the so-called Hy- 

 brid Remontants (H. R.) that wintered then under pro- 

 tection and came out in good condition. These varie- 

 ties may therefore be considered the most suitable for 

 this and kindred climates: Prince Camille de Rohan, 

 H. R. ; Magna Charta, H. Ch. ; Mrs. R. G. Sharman Craw- 

 ford, H. R. ; General Jacqueminot (Rousselet), H. R. ; 

 Captain Christy, H. T. (Hybrid Tea); La Rosiere, 

 H. R. ; Captain Hayward, H. R.; Mrs. Paul, Bour. ; Gar- 

 den Favorite, H. R. ; Louis Van Houtte, H. R. ; Paul 

 Neyron, H. R. (Fig. 2109); John Hopper, H. R. 



The following dozen were in fair condition after the 

 winter and recovered their form during the season: 

 Mme. Victor Verdier, H. R. ; Pierre Netting, H. R. ; 

 Anne de Diesbach, H. R. ; Ulrich Brunner, H. R. ; Bar- 

 onne Prevost, H. R. : Eugene Furst, H.R.; Prince of 

 Wales, H. R. ; Alfred Colomb, H. R. ; Lyonnaise, H. R.; 

 Mme. Gabriel Luizet, H. R. ; Countess of Oxford, H. R. 



The list of those that winter-killed is too numerous to 

 give, but it is a singular fact that the first list contains 

 forms classed among the Teas and Bourbons. Of the 

 climbing forms that were unprotected, Rosa setigera 

 and its offspring, Prairie Queen, were somewhat injured ; 

 but Greville (Seven Sisters), Crimson Rambler, Thalia, 

 Paul's Carmine Pillar, Multiflora and the Dawson Rose 

 were in fairly good condition when wintered under 

 protection. The failures even when protected were 

 Aglaia, Alister Stella Gray, Euphrosyne, Russell's 

 Cottage, Baltimore Belle, Tennessee Belle. The typical 

 Sweetbriers proved hardy unprotected, but the hybrids 

 of them were killed. Protected JR. Wichuraiana and 

 its hybrids killed back to the roots ; R. rugosa and 

 most of its hybrids, especially those of Jackson Daw-

 grown m the open air in the eastern and southern, 

 states can be grown only by systematic pruning and 

 winter covering. Of well-known old varieties hardy 

 enough to winter without protection, the list is short. 

 Madame Plantier, White Harison, and Rosa rugosa 

 with some of its hybrids, are hardy between the 40th 

 and 44th parallel, and still farther north the East Eu- 

 ropean R. rugosa and such of its hybrids as Snow- 

 light, Empress of the North and Rosa majalis ft. pi 

 are grown successfully. Figs. 2181 and 2182 show forms 

 or Rosa rugosa; also Figs. 2162-04. 



Of the newer hybrids of R. rugosa now quite widely 

 tested, the most desirable are I. A. C. (Fig. 2183), Ames, 

 Madame Georges Bruant (Fig. 2184), Madame Charles. 

 Frederick Worth, and Thusnelda. Kaiserin (Fig. 2185) is 

 also to be commended. It is suggestive that these have 

 come from crossed seeds of what is known in Europe as 

 Rosa rugosa,v&r. Regeliana (p. 1556), and which we know 

 as the Russian Rosa rugosa. The first two named came 

 from seeds of Rosa Regeliana introduced by the writer 

 in 1883 crossed with pollen of General Jacqueminot, and 

 the last three were developed from seeds of R. Regeliana 

 in Germany as stated by L. Spath, of Rixdorf near 

 Berlin. They are all fine double Roses of the class 

 shown in Fig. 2183, of the two produced at Ames, and 

 all have retained to a large extent the foliage and habit 

 of blooming of R. rugosa. The Russian R. rugosa as 

 introduced from Russia by the writer is divided into two 

 very distinct classes. The one from the Amur valley in.

North Central Asia is a very strong, upright grower- 

 with lighter colored bark, stronger thorns, thicker and 

 more rugose leaves, and larger flowers than the Japan 

 type, but its hips are smaller. The one from Russia in 

 Europe is spreading and pendent in habit. When 4 ft. 

 in height it has a spread of top of fully 6 ft. Its leaves.
