proved that cedars may affect quinces, or other amenable plants, at 

 a distance of eight miles. Evidently, the first thing to be done is 

 to destroy the cedar trees, if rust is feared. The next thing to do 

 is to destroy all affected portions of quinces, hawthorns, apples 

 and other plants upon which the rust stage appears. There is 

 some question as to how long the fungus persists in the quince 

 wood. It has been thought that the mycelium or vegetative por- 

 tion is perennial in the tissues of its host, but this is doubtful. I 

 believe that the rust can be kept off the quince by thorough spray-

ing with Bordeaux mixture. The disease was certainly less prev- 

 alent in the sprayed portion of Col. Bowen's orchard than in the 

 unsprayed part. If the leaves, fruits and twigs of the quince tree 

 are covered with the fungicide, the spores will find small chance 

 of making successful germination when they arrive from the cedar 

 trees. But this rust is rarely very serious, and if the grower has 

 sprayed dutifully for the leaf-blight, he will have little to fear. 



Pear-blight or fire-blight is undoubtedly the most serious dis- 

 ease with which the quince grower has to contend. It is the same 

 disease which is so destructive to pear orchards in certain years, 

 and which attacks various sorts of apples, particularly the crabs. 

 This is known from all other diseases by the death of the entire
