PLATE 30. 



Blighted quince-shoots and pear-fruits. 



velve inoculations were made arid all were successful — 8 quince-shoots and 4 pear-fruits. None of ihe checks contracted the disease. The organism was 

 introduced by delicate needle-pricks. The subculture used was derived from a poured-plate colony obtained from the mterior of one of the pears shown in 

 plate 29. Owing, no doubl. to the riper and therefore less susceptible condition of the tissues, and jxjssibly also to somewhat cooler weather, the disintegration 

 of the deeper tissues of the huits had not proceeded as far as in the pears inoculated on the same tree 10 days earlier ; in those fruits first inoculated the decay 

 was from 5 to 10 times as e.Ktensive on the 8th day as in the second inoculations on the 1 1th day. Inoculated July 20, 1905. Photographed July 31
