NEW PEARS. CLASS II. WINTER. 157 



in honor of Dr. Augustus Frederick Adrian Diel. Its 

 great merit, independent of its excellence, is its fertility. 

 It is of the first rank among dessert pears. The tree is of 

 vigorous growth. The fruit, when in perfection, is four 

 inches long, and three inches broad ; it is much swollen a 

 little above the middle, going off to the eye either abruptly 

 or gradually, and tapering straight to the stalk, without any 

 contraction of the figure, which is much like the Bon Chre- 

 tien, but without the protuberances. The skin at maturity 

 is bright orange, with little trace of russet ; its dots sur- 

 rounded with red ; the eye in a deep cavity, surrounded by 

 knobs ; the stalk strong, one and a half inches long, in a 

 deep, narrow cavity ; the flesh clear white, a little gritty 

 towards the core, but perfectly tender, melting, juicy, with 

 a delicious, rich, saccharine, aromatic flavor, without any 

 perceptible acid ; the core small, the seeds usually abortive. 

 The Sylvanche Verte, first sent by Mr. Knight to the 

 late Mr. Lowell, proved to be the Diel. With us the tree 

 bears abundantly, and in many situations this fruit is ex- 

 ceedingly fine, and without fault. I regret to add, how- 

 ever, that, with Col. Wilder, and some others near Boston, 

 this most noble winter fruit is liable to crack badly. 



153. BEURRE FORTUNE. Bon Jard. 



Large, roundish, gray; flesh beurree, melting. It keeps 

 till July. This new fruit was produced by M. Parmen- 

 tier, of Enghein. in 1828. Its character has probably been 

 too highly extolled, and is yet doubtful, and has not justi- 

 fied expectation, as M. Poiteau has informed us. 



154. BEURRE GRIS D'HIVER NOUVEAU. [J.J 

 Very excellent ; a new and valuable fruit, of medium 



size, melting and perfumed. It keeps till the end of winter, 

 or till spring. 



v 156. BEURRE DE NOIRCHAIN. [J.J 



A new and very superior fruit, very melting and per- 

 fumed ; of medium size. This valuable fruit keeps till 

 spring. This fruit and the following are designated as 

 very extraordinary. 

 157. BEURRE PICQUERY. [J.] [D.] 



New and very superior ; of medium size ; very melting 

 and perfumed. This fruit keeps till into winter, and is 

 stated to be the best of all pears known, and of unrivalled 

 excellence.
