or j)ieces of bark concave below, where tlie ciirculio will gather to 

 avoid the cold, removing them daily. 



From these facts, somfe recommend the hanging of open ves- 

 sels containing a liquid, in the branches of the trees, having burn- 

 ing lamps over tubs, or building small fires about the grounds — 

 the insects being attracted by the light, fly into the flames and 

 vessels and perish. 



The peach borer (geria exilisa) does his work by girdling 

 the bark of the tree, just below the surface of the ground. Its 

 presence can always be discovered by the exuding of the sap or gum 

 at that particular point. 



The perfect insect is a four-winged moth, of a bluish color — 

 depositing during the summer its eggs at the base of tiie trunk, its 

 larvae enters the bark and wood — the transformation requiring 

 about a year. 



As soon as their appearance is made they should be cut with a 

 knife, or punctured in their recesses by a sharp instrument, re- 

 moving the soil from about the tree ; in the cavity thus made, a 

 half peck of our slacked lime and ashes should be heaped around 

 the trunk, this removed and worked into the soil in autumn. 



Other remedies are recommended, but the foregoing, if per- 

 formed annually, will be found perfectly effectual.* 



Mildew sometimes aj^pears on the ends of young twigs — the 

 nectarine and peach trees with serrated leaves are more subject to 

 its attacks than others. This is not a serious malady ; checks 

 the growth and deforms the appearance of the tree ; this is over- 

 come by cutting away such branches that have been injured; dust- 

 ing with sulphur and syraying with water impregnated with nitre, 

 in a mixture of an ounce of the latter to a gallon of water, are 

 remedies ; the latter while destroying disease, will add new health 

 and vigor to the tree. 



The curl is developed on tlie first leaves in spring. They 

 become red, brown and seared, swelling into odd shajjes, and in two 

 or three weeks fall. This is caused by the punctures of a small 

 plant louse (the aphis persica), ujjon the under side of the leaves. 

 Applications with a syringe of a mixture of strong soapsuds and 

 tobacco-water has been found a good remedy to exterminate the 

 aphis. 



Barry regards the curl of the leaf induced by sudden changes 

 of weather. The young leaves caused to expand by warm days, 

 followed by cold and rainy ; the more severe and protracted the 

 cold, the more fatal and severe the curl.
