Two different washes were prescribed to keep rabbits and field mice 

 from destroying the bark of trees and shrubs. One is whitewash, the 

 lime thinned with a solution of glue and enough carbolic acid added to 

 make the mixture smell strong. The other is a mixture of lime, sulphur, 

 and Cayenne pepper. The first of these mixtures will also destroy any 

 eggs of insects that may have been laid on the bark. 



To prevent the spread of orchard pests it was strongly advised to 

 collect all fallen apples, or to allow pigs and chickens to run in the 

 orchard and help themselves. The eggs or spores of the blight remain 

 in the rotting apples and are ready for dissemination, according to their 

 kind, in the spring. 



Dust spraying was the subject of one discussion, and the number in 

 its favour, as against liquid spraying, was small. — M. L. H. 



Montanoa mollissima. By J. Hutchinson (Bot. Mag. tab. 8143). — 



Nat. ord. Compositae ; tribe Helianthoideae ; Mexico. A shrub 6 feet 

 high ; leaves sessile, 4-7 inches long ; capitula 1^ inch diameter ; ray 

 flowers white ; disk yellow. — G. H. 



Montbretias, Hybrid. By G. T. Grignan {Rev. Hort. May 1, 

 1907, p. 208 ; coloured plate). — The plate shows four very fine varieties : 

 ' Grand Moulin,' large, petals half-yellow merging into deep orange-red ; 

 ' Bicolor,' three petals deep orange-red and three bright yellow, flowers 

 smaller ; 1 Chrysis,' bold, broad-petalled, bright yellow flowers ; and 

 ' Flamboyant,' very large, rich red. — C. T. D. 



Mulching- Garden Vegetables, Experiments in. By R. A. 



Emerson (Agr. Exp. Stn. Nebraska, Bull. 80). — The results are given 

 of mulching versus thorough cultivation. The experiments were tried 

 with ordinary garden vegetables, and would seem to show that those 

 vegetables benefit most from mulching which require a long season of 

 growth and frequent cultivation, an advantage being that the mulch can 

 be applied before the rush of summer work begins. Tomatos, cucumbers, 

 and cabbage benefited most by mulching. — C. H. L. 



Mutation, Induced (Rev. Hort. March 1, 1907, p. 199; and 

 July 1, 1907, p. 205). — It is stated in the " Journal d'Agriculture 

 Pratique," in a report on experiments by MM. Blaringhem and Bonnier, 

 that by means of transverse or longitudinal stem wounds, or by bending 

 the plant concerned, especially maize, permanent and inherited sports 

 or mutations have arisen possessing agricultural value. See also 

 L. Daniel (Rev. Hort. August 1, 1907, pp. 356-7), similar experiments 

 with roses and results through graft disturbance. — C. T. D. 



Naming Plants. Anon. (Gard. Chron. No. 104G, p. 17, 



January 22, 1907). — A condensed account of the rules, &c, of 

 nomenclature of plants adopted at the International Congress of 

 Botany held at Vienna in 1905 is given. The rules are published 

 in three languages (French, English, and German), bound together in 

 a paper cover : they may be obtained from any foreign-bookseller.
