anists to be the same species. At any rate, the chief 

 points in the life-history and remedial treatment are the 

 same as for the apple disease. Spray with dilute 

 Bordeaux mixture, first as soon as fruit buds open ; 

 second just before blooming; third as soon as blossoms 

 fall, and fourth about three weeks later. 



Care should be taken not to apply the Bordeaux 

 mixture too late in the season. Early varieties should 

 have but one spraying with this mixture after the fruit 

 "sets," and late varieties but two. Where additional 

 applications are needed, use the copper carbonate 

 solution. 



Pear trees, especially older ones in southern lati- 

 tudes, as well as apple trees, are often largely covered 

 with LICHENS of various kinds. Recent experiments 

 by Mr M. B. Waite show that these are destroyed by 

 spraying with the Bordeaux mixture. 



The quince is subject to the leaf -blight above 

 discussed as a pear pest, and to various other diseases. 

 As a general rule, it should receive treatment similar 

 to that given the pear, although a larger number of 

 sprayings seem to be necessary.
