Mole, The Common. By Theo. H. Scheffer {U.S.A. Exp. Stn. 

 Kansas, Bull. 168; illustrated). — An interesting account of the life 

 and habits of the common mole {Scalops aquaticus). The author 

 recommends trapping as the surest means of getting rid of moles, 

 although poisoning with strychnia sulphate is frequently practised with 

 good results. Eaisins poisoned by removing the seeds and inserting 

 crystals of strychnia have also proved effective when placed in the 

 runways. — V. G. J. 



Mosquitoes, Preventive and Remedial Work against. By 



L. 0. Howard, Ph.D., {U.S.A. Dep. Agr. Bur. Entom., Bull. 88; 

 June 20, 1910). — An interesting account of the crusade against mos- 

 quitos and malaria, which is being carried on vigorously in many parts 

 of the world. 



The chief methods of extermination and prevention are: (1) the 

 draining of all marsh lands, especially salt marshes (the land thus 

 drained and reclaimed can in most cases be made agriculturally useful) , 



(2) abolition of accidental breeding places, such as surface water, rub- 

 bish heaps where water may accumulate, and catch basins in sewers ; 



(3) encouragement of certain natural enemies of the mosquito, i.e., 

 gold-fish, minnows, stickle backs, and dragon-flies; (4) the application 

 of a surface film of low-grade fuel oil, kerosene, or petroleum on tanks, 

 ponds, or any water that is known or suspected as a breeding place. 

 The writer considerately includes in the bulletin remedies for those 

 who are unfortunately bitten; these are glycerine, soap, naphthaline 

 moth-balls, and a liniment composed of 30 grains of iodine to 1 oz. 

 of saponated petroleum, all of which have proved efflcacious. — V. G. J. 



Nectarine 'President Viger,' By Pierre Passy {Rev. Hort. 

 October 16, 1910; p. 76; coloured plate). — Eaised by M. A. Chevreau, 

 Montreuil, from a stone of a clingstone nectarine received from the 

 Cape, and sown owing to the brilliant colouring of the fruit. The 

 result is a much improved freestone nectarine of robust character and 

 easy culture and very handsome. — C. T. D.

Nicotiana, hybrid (Tafcaca x sylvestris var. ' Madame Maurice | 

 Granel.') By D. Bois {Rev. Hort. September 1, 1910; p. 397; one 

 illustration). — As a result of crossing these two species one plant of the 

 second generation has assumed a remarkably robust growth, about 

 7 feet high, with huge leaves and large white flow^ers, and has stood 

 several winters in the open, merely mulched with leaves. The photo-
