Pears, Gathering* of . By Gabriel Lulzet {Pom. Frang., 2, Feb 

 1911). — A long discussion as to the merits and time of gathering j |!y 

 of ' Beurr^ Blanc' The general advice given as to the gathering of 

 Pears with a view to storing is as follows : — 



" The early Pears should be gathered some time before they are 

 apparently ripe. This interval should be gradually shortened as the 

 medium varieties are reached, and the late kinds must be left as long 

 as possible on the tree." This is sound advice, and may be justly i 

 applied to Apples also. — E.A.Bd. ,
