is checked by the tar, and they congregate in the holes in large numbers. 

 The holes are then filled in and stamped on, and fresh holes dug.

Romneya Coulteri, Propagation of. By S. (Garden, p. 25, Jan. 13, 

 1912). — This may be effected by seeds or root cuttings. Seed is sown 

 as soon as ripe, but there was found a difficulty in this, for when the 

 plants were large enough to pot off only a few recovered from the 

 disturbance. Root cuttings are made from the suckers or thick fleshy 

 roots, which can be obtained by a trowel from old plants. The plants 

 should not be disturbed, as they cannot be replanted with success. 

 The pieces of root, 2 to 4 inches long, are laid horizontally in pot or pan, 

 and quite covered with soil ; when they push out shoots they may be 

 severed, leaving a piece of root to each shoot. The rooting medium 

 should be loam, leaf-mould, and silver sand in equal parts. — H. R. D. 



Rosa Moyesii. By B. (Garden, p. 326, June 29, 1912). — Three 

 years ago " B." purchased this Rose and planted it in a border facing 

 south and west. It produced only half a dozen flowers each season, 

 and he thought it a bad doer. In the autumn, 191 1, he transplanted 

 it to a border with a south-east aspect. It has since produced a 

 sheet of bloom of some 150 flowers, and is sending up basal shoots 

 5 feet high. 



(The abstractor has just performed the reverse operation for a 

 similar reason. The removal may have increased the flower-bearing 

 capacity of the plant.) — H. R. D. 



Roses for Perfume. By Marcel Bossiere (Jour. Soc. Nat. 

 Hort. Fr., ser. iv., xiii. ; May 1912). — Bulgaria has hitherto been the 

 great centre of Rose production for the manufacture of Essence of 

 Roses. It has been carried on by peasants mostly on small holdings, 

 and the spirit is produced on the spot by the cultivator himself, and 

 any large quantity of it together is liable to an unpleasant smell 

 through faulty methods of distillation. M. Jules Gravereaux has been 

 trying for many years to produce the perfect Rose for the production 

 of Essence. The two kinds mostly cultivated in Bulgaria are R. 

 centifolia and 1 R. damascena, and M. Gravereaux has raised a new 

 hybrid between R. damascena and R. ' Gen. Jacqueminot,' this 

 being again crossed with R. rugosa. The result, which he has called 

 ' Rose a Parfum de l'Hay, ' is, however, said to be inferior in vigour 

 and floriferousness to a production of M. Cochet's ' Roseraie de l'Hay,' 

 which is now being cultivated on a fairly large scale in Provence and 

 Germany for the purpose of distillation and is said to be inaugurating 

 a profitable industry. — M. L. H. 



Rhododendron Smirnowi (Die Gart. p. 147 ; March 16, 1913 ; 

 with illustration). — One of the most distinct and showy of the perfectly 

 hardy species. A native of the Caucasus. It is a handsome evergreen
