Peaches of the Peen-to Group (U.S.A. Exp. Stn. Florida, Bull. 

 62 ; 7 1902 ; 3 plates). — Peaches of this group are described as being 

 specially adapted for growing in Florida and the coast regions of the 

 Southern States. This Peach was introduced early in the nineteenth 

 century to England under the name of Java Peach (Trans. Hort. Soc. 

 vol. iv., 512-513, pi. xix.), and into America about 1828. It has given 

 rise to about twenty-two varieties, which are described in the present 

 bulletin.— F. J. C. 



Peach Scales, TWO. By H. A. Gossard (U.S.A. Agr. Exp. Stn. 

 Florida, Bull. No. 61, 1902, pp. 473-498).— The species dealt with are- 

 the San Jose (Aspidiotus perniciosus) and Diaspis pentagona ; neither of 

 which is found in Great Britain. 



" Crude petroleum of 43 to 45 degrees specific gravity applied in 20 

 per cent, mechanical mixture with water is an efficient winter remedy 

 for both of the above-named scales. 



"The trees should be banked with earth about the roots to catch the 

 surplus spray, and the application should be made on a bright sunny day. 

 The spray- soaked earth about the roots should be removed within half an 

 hour after the work is completed. 



" One thorough application while the buds are swelling or ready to 

 burst is sufficient and is recommended. 



A Kerowater machine with Vermorel nozzles should be used, or if 

 an ordinary pump is employed an emulsion must be prepared. — B. N. 



Pear Gnat Midge, The. By E. Bartrum, D.D. (Gard. Mag. No. 

 2554, p. 664 ; 11/10/1902). — The writer describes another enemy to the 

 Pear, Diplosis pyrivora, a very small fly not unlike a gnat, the grubs of 

 which attack the young fruits, causing them to turn brown, then black. 

 With characteristic devotion to detail, he gives the life history of this little 

 pest, and suggests remedies against its attacks ; but on this point he is 

 apparently undecided. Probably later on an effectual remedy will be 

 discovered, but at present it seems that science is not superior to insect 

 attack (see p. cxxxvii). — W. G. 



Pear-leaf Blister Mite. Anon. (Gard. Mag. No. 2544, p. 503 ; 

 2 6 1902).— A descriptive note (illustrated) of the insect pest which
