Rock-garden making. By F. W. Meyer {Garden, No. 1695, p. 335 ; 

 14/5/1904). — This is an article, of a series, dealing with water in the 

 rock garden. Picturesque vegetation, blended with rocks and running 

 water, is the most fascinating picture Nature can produce. Hence, in the 

 rock garden, where we try to follow Nature's laws in the arrangement of 

 everything, the addition of water is a most important factor. Without 

 the presence of any water whatever very interesting and even picturesque 

 rock gardens might be constructed ; but so great are the additional ad- 

 vantages of water that whenever the chance occurs to have it introduced 

 into the rock garden it would be foolish not to take full advantage of such 

 a chance. Nor is it from a picturesque point of view only that water is 

 so desirable, but it is most useful as well. Since mountain plants from 

 high alpine regions require a moisture-laden atmosphere to flourish in, 

 this can be supplied in the rock garden through the constant evaporation 

 from ponds or streams. — E. T. C.

Rosa polyantha and Varieties. By Philomel (Garden No. 1703, 

 p. 25 ; 9/7/1904). — Botanists make R. polyantha a variety of R. multiflora. 

 There is, however, a great difference, so far at least as gardens are con- 

 cerned. Many of the varieties of R. multiflora, such as ' de la Grifferaie,' 

 1 Laure Davoust,' and ' Crimson Rambler,' are double. The true R. poly- 

 antha has immense and dense clusters of white single Blackberry-like 

 blossoms that are so abundantly produced as to give the plant a marvellous 

 decorative character for a few weeks. To see this fine Rose in its glory 

 one should plant it where its branches may fall outward and overhang 

 a rockery or some old roots or stumps of trees. It is also a beautiful 

 plant for the wild garden. — E. T. C.

 Norbert Levavasseur ' {Rev. Hort. p. 325, July 16, 1904).— If the 



latter be grafted on the former, a successive flowering on very similar 

 lines is secured. — C. T. I). 



Roses, Own-root. By Practitioner (Garden No. 1703, p. 24; 

 9/7/1904). — No one who has seen the luxuriant growth- of an own-root 

 Rambling Rose can ever desire any other. How freeiy the new growths 

 break from the base, compelling the cultivator to cut away the old wood to 

 make way for the new, and by so doing keeping the plant in a youthful 

 flowering condition ! In this way should be grown more especially the 

 bedding or massing Roses, also those for hedges, and all that are grown 

 in the free rambling way, for draping and garlanding trees, pillars, and 

 arches with their wreaths of blossom. — E. T. C. 



Roses, White Bedding {Garden, No. 1715, p. 220; 1/10/1904).— 



It is astonishing how many Roses, when seen from a short distance, 

 are white in effect, though on close inspection there are subtle charms and
