54 THE CANADIAN HORTICULTURIST. 



takes the disease, and finally perishes ; and that the seeds of the dis- 

 eased trees produce young trees in which the yellows sooner or later 

 breaks out." 



There are two or three infallible indications of the existence of the 

 yellows in a peach tree, and among these may be mentioned, 



(1) Tha 2)Te')aature ripening of the fruit. This will be the first 

 observable symptom, and should the tree survive for two or three years, 

 eiich recurring season will witness a still earlier time of maturity. This 

 sympton may be to a certain extent counterfeited by the work of the 

 larva of JEgeria exitiosa, which girdles the tree just below the surface 

 of the ground, and which also may prove the death of it. But to the 

 experienced cultivator the next symptom will be unmistakable, viz : 



(2) The spotted fruit. Whether naturally yellow or purple, the 

 fruit of such trees as are affected with the yellows is invariably dotted 

 with purplish red spots ; while the flesh is highly colored about the 

 pit. Such fruit is sometimes shipped into our country in large 

 quantities to be sold to the uninitiated, and the people of our towns 

 and cities should be on their guard against it, for it is insipid and 

 worthless. There is one more symptom which may be depended upon 

 as unfailing, and that is 



(3) The appearance along the 'branches of long slender shoots, 

 hearing small narrow leaves. These leaves are usually of a yellowish 

 color, from which characteristic we have the name of the disease. 



Among the measures to be adopted by peach growers to prevent 

 the spread of the yellows, we may mention, (1) the use of the greatest 

 caution in the purchase of hoth pits and trees. Not only sliould the ' 

 pits of natural trees be chosen for propagating,* as possessing most 

 health and vitality, but they should be gathered from trees that are 

 themselves vigorous and healthy, lest a deterioration be setting in 

 which may prove to be the beginning of troubles. By all means should 

 pijbs be avoided by the planter that have been grown in districts where 

 the yellows are known to prevail; and surely the ominous words 

 sometimes seen in advertisements of pits for sale, viz, "Warranted free 

 from the yellows," should be warning enough to lead the buyer to 

 make sure in this matter. 



As for the trees themselves, since they do not exhibit any indi- 

 cation of disease until sometime planted, the buyer needs to enquire 

 carefully into their nativity, and he must not buy from those sections
