280 THE CULTIVATION OF THE 



should be so cultivated, and their habits studied. They 

 should be inoculated into healthy pear trees, such 

 as the Seckel and Duchess, which rarely, if cvjr 

 blight, and then, again, into the Vicar and Clapp's 

 Favorite, which almost always blight, sooner or later. 

 The leaves and fruit, as well as the bark of the trees, 

 should be inoculated, and the results watched and 

 studied, and by these means we might get at once the 

 history, habits and life of the disease-germ and a remedy 

 against its ravages. Who is to do this? Who can, but 

 the State or National Government ? This matter will be 

 referred to further on. This pear tree blight is certainly 

 a local fungus, and may be be developed by any one of a 

 number of causes. As when the wood don't ripen well 

 the previous year, and then, next summer, with high 

 temperature, with the wood-acid and nitrogenous matter 

 present, here will be the soil for the development of the 

 blight fungi, or, of one of them, for I believe there may 

 be a number coming under different circumstances. 

 Stagnant water contains germs and breeds them, that 

 may enter the pear-roots and cause blight, and hence, 

 drainage must be attended to in the pear orchard, and 

 hence, a sandy loam, well drained, is good ground for 

 pears.
