School Gardens. By F. M. Powell, M.D. {U.S.A Hort. Soc. loioa, 

 Ann. Rep. for 1899, p. 141). — An instructive and interesting paper, dealing 

 with the subject mostly from a historic point of view. The writer starts 

 with Italian cities at the beginning of the 14th century, where there 

 were institutions in which plants were raised for purposes of education 

 and science. Botanical gardens in European countries and the United 

 States at the present day are referred to, and an appeal is made for the 

 establishment of school gardens for the education of children. — V. J. M.

 p. 561, pi. 1,492 ; 1/11/1901). — A coloured plate and short article on this 

 South Brazilian climber belonging to the Asclepiadacece. The flowers 

 are pure white, with a strong odour something like that of Jasmine. The 

 plant requires treatment similar to that needed by Stephanotis florihuiida. 

 A short paragraph on its cultivation by Victor de Coene is given on p. 562

^QQ^S {Wohurn, 2nd Bep. 1900, p. 210). — Experiments made with 

 the germination of seeds from large and small fruits of Apple and Pear 

 trees seem to show that neither the size of the fruit nor the number of 

 seeds per fruit has any certain efiect on the gerimnating power of the 

 seed, and probably not on the vigour of the seedlings. — C. H. H. 



Seeds, Growing* and Saving* Field and Garden. By F. S. White 

 {U.S.A. Hort. Soc. loioa, Ann. Bep. for 1899, p. 435). — A paper dealing 

 with Corn seed and Potato seed principally, and concluding with other 

 seeds. Some valuable advice is given, and the results of experiences in 

 Iowa are described. Some useful hints upon seed storing. The writer 

 when speaking of Potatos seems to have no fear of the old hard-shell 

 Colorado beetle, but deals seriously with the black or brown Potato flea.
