subjects, recommended artificial fertilizatioD. By om- present haphazard 

 system we are only in a position to be sure of the mother plant, and 

 all our good varieties have come by chance. It would be a great 

 advantage if we could also choose the male parent. The first genera- 

 tion often gives a new plant of no interest in itself, but which holds 

 the power of variation, and may possess in a latent condition characters 

 which will sow in successive sowings. Seed should be gathered with- 

 out cross-fertilization, and in successive generations an interesting new 

 plant may result. Unfortunately, this is a long process with pears, 

 as they do not flower until they are eight or nine years old. — M. L. H. 



Pears, New stock for. By J. A. Kleyhonz {Oestr. Gart. Zeit. 

 vol. vi. pt. xii. pp. 4:60-3).— Pyrus sinensis is recommended as a stock 

 for grafting pears. Time will show whether it answers expectations.

Pecan Cigar Case-bearer, The. By H. M. Eussell {U.S.A. 



Dep. Agr,, Bur. Entom., Bull. 64, pt. x. ; Nov. 1910; 3 plates, 

 2 figs.). — The pecan cigar case-bearer (Coleophor coryloefoliella Clem.) 

 is an insect of minor importance and feeds principally on nut-bearing 

 trees, such as the walnut, pecan, and hickory. The larvae feed on 

 the tender buds and unfolding leaves. The larval case resembles a 

 minute cigar. 



Where the insect is abundant enough to be injurious it can be 

 controlled by spraying the trees with arsenate of lead (3 lb. to 50 

 gallons water) when the buds are swelling. 



Lime-sulphur mixture applied during the dormant season would 

 give good results. Where trees are sprayed in spring for the bud- worm 

 [Proteopteryx deludana Olem.) no further treatm^ent will be required 

 for the case-bearer.— y. G. J. 



Pelarg-onium grrandiflorum. By E. Foucard (Rev. Hort. 

 pp. 523-4; Nov. 16, 1911; coloured plate).— The plate represents 

 three very handsome forms, viz. ' Madame Ed. Mace,' pale mauve 

 with radiating crimson centre ; ' Caprice de Nini, ' white suffused 

 with pink and striped centrally and radially with carmine and ' F. de 

 Lesseps,' intense crimson with light rose edges. Flowers bold, in 

 good clusters. These represent the choicest of those shown in the 

 Cours-la-Eeine Exhibition. A descriptive list of others is given.

Peony, * Souvenir du Professeur Maxime Cornu.' By D. 



Bois (Rev. Hort. p. 472-3; Oct. 16, 1911; coloured plate).— The plate 

 represents an extremely fine double form of Peony, a cross between 

 * Madame Louis Henry ' (P. Delavayi lutca) and * Elizabeth ' (P. Mou- 

 tan). The flowers are very large, about 8 inches across, are perfectly 

 double, and of a bright canary yellow, with the edges of most of the 

 petals, especially in the centre of the flower, irregularly margined with 

 crimson. Other very handsome liybrids of similar class are men-
