Paper Birch in the North-East. By S. T. Dana {U.S.A. Dep. 

 Agr. Forest Service, Circ. 163, July 1909). — In addition to several 

 important uses to which the timber of the paper birch (Be tula papyrifera) 

 — a tree which, by the way, does well in this country — is applied, it is 

 largely used in the making of toothpicks and for shoe-pegs, no fewer 

 than 3000 cords being annually consumed in the manufacture of the 

 former alone. — A. D. W. 



Peach, *Theophile Sueur.' By Pierre Passy [Rev. Hort. 

 Dec. 16, 1909, pp. 574-575; col. plate). — Eaised from ' Grosse 

 Mignonne Latue.' According to the plate, this is an extremely hand- 

 some fruit of a deep rich crimson colour, which tint surrounds the 

 stone star fashion, as shown by section. — C. T. D. 



Peach-tree Bark Beetle. By F. F. Wilson (U.S.A. Dep. Agr., 

 Bur. of Entom., Bull. 69, part 9; Feb. 1909; figs.).— This beetle 

 bores into the bark of peaches and often causes the death of the trees. 

 The tunnels are not unlike those of Scolytus rugulosus, which also 

 occurs in peaches and in other tress in Great Britain as well as in 

 America. The life history of the pest (Phlaeotrihus liminaris, Harris) 

 is described and the various stages are figured. The methods recom- 

 mended for dealing with it are applicable to several other boring beetles 

 and are as follows: — 



For Trees seriously Injured. — Severely trim back the trees and apply 

 barn-yard manure or commercial fertilizers ; then apply a thick coat of 

 whitewash three times a season, the first application to be made the 

 last week in March, the second during the second week in July, and 

 the third about the 1st of October. 



For Trees apparently Healthy hut slightly Attacked. — Paint the trees 

 with a thick coat of whitewash three times each season, as in the 

 previous treatment, applying it to the trunks and larger limbs. The 

 whitewash applied at the times specified will act as a repellent, the 

 emergence of the beetles being slightly later than the dates given for 

 the different applications. Add ^ lb. table salt to each pail of white- 

 wash, thus making the latter more adhesive. All the dead or nearly 

 dead limbs and trees should be removed and burned as fast as they 

 appear in an orchard, as this will destroy the breeding-places. 



These suggestions are made as the result of experiments, and if 

 they were followed for similar pests they would need to be modified to 

 some extent, according to their life-histories. — F. J. C. 



Peanuts. By W. R. Beattie (U.S.A. Dep. Agr. Farmers' Bull. 

 356, May 1909 ; illus.). — Peanuts constitute an important crop in 

 the States, but should be still more grown in the waste lands of the 

 Southern States, . and so avoid the necessity for buying peanut oil 

 abroad. The fodder is also good. The peanut requires a long season of
