by Loudon " The White Beam-tree-leaved Sph^aea " on account of a 

 fancied resemblance to Pyrus Aria. The flowers are cream-coloured 

 and borne in terminal panicles in July. It grows in any ordinary 

 garden soil, and may be increased by cuttings in summer or by seeds. 

 It has been known as S. ariaefolia, and there is a dwarf variety, 

 S. discolor diimosa. — H. R. D. 



Sports," The Production of. By G. T. Grignan {Rev. 



Hort., Feb. 16, pp. 86-87).— A consideration of the theory that 

 " sports " in such flowers as the Eose and Chrysanthemum are induced 

 by propagation to an extreme extent by cuttings. Eesearch, however, 

 demonstrates by the very diverse evidence obtained that it is rather 

 due to an innate tendency which asserts its potency very waywardly, 

 and cannot so far be imputed to any definite influence. Nature does 

 as she pleases," and man can only profit by the chances she gives him.

Spraying'. By W. J. Allen and J. G. E. Bryant (Agr. Gaz. 

 'N.S.W. March 1910, pp. 251-255).— Spraying with fungicides should 

 be carried on at regular intervals of about two weeks during spring and 

 early summer. They are preventives, and must be used before the 

 disease is prevalent. Two kinds of insecticides are used — a poison for 

 leaf-eaters and an irritant for sucking insects such as plant lice. A 

 nozzle of the Vermorel type is best for general use. A good pump and 

 nozzle are essential for successful spraying.— >S'. E. W . 



Spraying* Fruit Trees and Bees {Agr. Gaz. N.S.W. March 

 1910, p. 196). — To avoid injury to bees do not spray trees in bloom; 

 wait till the petals have fallen. — S. E. W . 



Spraying": Information concerning* Orchard Insects. By 



A. L. Quaintance {U.S.A. Dept. Agr. Year Book, 1908; 11 pp.; 

 5 plates).— ^A discussion of spraying in general. As a winter wash the 

 lime-sulphur mixture is strongly recommended, and is stated to destroy 

 eggs of Psylla and the Pear-leaf blister mite, Eriophyes pyri. A list of 

 chemicals used in various sprays and a discussion of their qualities is 

 given. The plates depict various spraying outfits, most of which are 

 known in this country. — E. A. Bd. 



Stenog'lottis long'ifolia. By U. Dammer {Orchis, vol. iv. 

 pt. iii. pp. 43-44). — A description of the flower of Stenoglottis longi- 

 folia which bloomed at Dahlem in October 1909.—^. E. W. 



Storagfe of Pears. By G. Marunteaun {Pom. Frang. pp. 5). — 

 An important paper on certain methods adopted by the writer in storing 

 his pears. The years most favourable to this fruit are those when rains 

 fall during swelling of the fruit. A register of temperature (in shade) 

 is kept, and certain varieties are found to require a longer exposure to 

 heat than others for perfect ripening and conservation. Fruits well 

 exposed are gathered first, e.g. Duchesse d'Angouleme. Fully exposed
