Pineapple Culture. By K. K. Miller and A. W. Blair (U.S.A. 

 Exp. Stn. Florida, Bull. 83-84 ; 1906 ; figs.).— These bulletins give the 

 results of fertiliser experiments on pineapples, with recommendations 

 for the use of certain manures based on these results, particulars as to 

 packing-houses, field equipment, packing, grading, and everything con- 

 nected with the marketing of the fruit. — C. II. H. 



Pineapple, Fungus Diseases of. By F. A. Stockdale, B.A. 



(Journ. Imp. Dep. Agr. W.I. 1907, 2). 



Tangle Root, not traced to any fungus as its cause, but probably due 

 to poor preparation of the land. 



Blight. The fungus that accompanies the discoloration and softening 

 of the roots has not been identified. 



Black Heart, or Core Rot. The fungus causing this disease is 

 attributed to the Mucedines, but has not yet been identified. 



Disease of Stored Pineapples. The commonest fungus in this 

 connection is the fungus of the sugar-cane, Trichosphaeria sacchari, 

 together with a species of Diylodia and some moulds of the genera 

 Penicillium and Aspergillus. 



A subsequent note on pineapple disease in Hawaii determines that 

 disease to be caused by Thielaviopsis ethaceticus. 



Cane cuttings can be protected from this disease by the application of 

 Bordeaux mixture to the ends. — M. C. C.

 July 5, 1907). — Part I. of an interesting historical article on pinks in 

 general. — F. A. W. 



Plant Breeding- in its Relation to American Pomology. By 



W. M. Munson (U.S.A. Exp. Stn. Maine, Ann. Rep. 1906; pp. 149- 

 176). — A very interesting account of the methods of work heretofore 

 used in the raising of new varieties, beginning with that of Van Mons with 

 pears, begun in 1785, and Thomas Andrew Knight, and later in America, 

 where Russian, Chinese, Japanese, and native fruits have been freSly 

 crossed with European, giving varieties suited to the various special 

 conditions obtaining in that country. The various common fruits are 

 then dealt with individually. — F. J. C.
