 the roots are said to be scahled ; because, at their 

 shallow position, they are unable to obtain sufficient 

 moisture for tlie supply of the leaves, which, by their 

 abundant evaporation, lower the temperature of the 

 sap — vapor being so perfect a conductor of heat. The 

 frozen sap-blight has not, within the memory of man, 

 been known to visit the localities above-mentioned,
