1120 FRUIT GROWING 



M. Louis Chasset carried his scheme into effect. According to his 

 method, the pears are first of all studied as regards the dimensions in 

 height and breadth. 



First class : Fruit of the same bioadth as height . 

 Second class : I'ruits broader than they are high. 



Third class : Fruits higher than they are broad : i/io t(j 2/10, 3/10 to 4/10. 

 Fourth class : Fruits higher than they are broad : 4/10 and more. 

 The first and second categories comprise the following forms : spheriform, short turbini- 

 jorvi, short doliform, short cydonifurm, maliform and flattened tiirbiniform. 



The third class comprises: d«li forms, ovoids, turbiniforms, truncated turbinifurms, piriforms, 

 truncated piriforms arid cydoniforvis . 



The fourth class comprises the last forms adopted : /oui; piriforms, calebassiforms and 

 oblongs. 



In each of these forms, 21 periods of ripening were created : June, 

 June- July, July-August, etc. 



Each of these times of ripening presents a picture in which the colours 

 of the skin of the fruit are noted ; these colours are: dark green, light green, 

 reddish, russet or bronzed ; the yellowish colour put down at first was after- 

 wards struck out as being useless. 



After the colour of the skin the next thing dealt with is the stalk, which 

 is divided from the point of view of dimensions into long, medium or short; 

 and of consistency, into fleshy or not fleshy at the base ; and of position, 

 into straight, oblique or arched. 



Carrying the selected characters still further, the flesh is next examined 

 as to its colour : white, yellowish, greenish, salmon ; then as to its taste : 

 sweet, acid, wine, musk, tart. 



The complete work comprises 5 volumes, the contents of which have 

 been condensed into a single volume which forms a popular edition. Mr. 

 Chasset, in order to facilitate this demonstration to the public, has prepared 

 8 tables, summing up the whole of his work. Thanks to these tables, 

 various fruits were classified with great facility and rapidity by a meeting 

 to which ]\Ir. Chasset submitted his work. 



870 - Pytus calleryana, an Interesting Species of Pear Tree. — Rmmer, f. c, in 



The Monthly Bulletin of State Commission of Horticulture, Vol. V, No. 5, pp. 166-171,

In 1908, Mr. George Compere, during a voyage in China, was struck 

 by the resistance of a species of pear tree to " pear blight " or necrosis of 

 the bark of the branchs {Baallus aniylovonis [Burr.] De Toni); he therefore 

 introduced this sj^jccies into California, believing it to be the " Chinese sand 

 pear", Pyriis sinensis Lindl. The writer has studied this pear tree, and 

 found that it was not P. sinensis but the species Pyrus Calleryana De- 

 caisne. P. Calleryana occurs very widely in China, where it is found both in 

 the south, the ea.st, the centre and the west. It grows at all altitudes up to 

 5000 feet. It is distinguished from P. sinensis by its leaves, which ore rela- 

 tively shorter, wide, with rounded or widened base, and with rounded or 

 crenate teeth along the edges. In addition P. Callctyana generally has
