ourculio. I think there are two kinds of curculios — one that at- 

 tacks the peaches and one the plums. 



Mr. Nowlin, of Arkansas — If any country is the home of the 

 AVild Goose plum, Arkansas is, but we are troubled with the curcu- 

 lio also. I have saved the crop, however, by sowing powdered 

 slacked lime upon the trees. 



Mr. Beatty, of Kentucky — I have had considerable experience in 

 this matter, and I find that the use of the sheet in catching curcu- 

 lios will save the fruit. 



Mr. Hullister, of Illinois, spoke of the difference between the cur- 

 culio and the plum gouger. The first makes a crescent-shaped inci- 

 sion in the fruit, and the gouger only makes a simple perforation. 



Mr. Galusha, of Illinois — The curculio does less damage to the 

 Wild Goose plum than to any other variety, because the eggs 

 laid in the plum are killed by the acid juices of the fruit. 



The following paper, by one of the most justly noted scientists of 

 the West, although present at the meeting, in the absence of the 

 author, was not read. The topic, "An Orchard Scourge," seems ap- 

 propriate to come in at this juncture. The name of Prof. T. J. 

 Burrill is, in the opinion of the Secretary, a sufficient passport to 

 position in the body of this report : 



AN ORCHARD SCOURGE. 

 (Fttstdadium deudriticum.) 



BY PROF. T. J. BURRILL, OF ILLINOIS. 



Everyone must have noticed last year (1882) a peculiar shriveling and 

 curling of the leaves of apple trees, beginning, in many cases, soon after the 

 bursting of the buds in springtime and continuing, more or less, during the 

 season. Many trees really never gained full foliage during the summer, but 

 throughout the year looked starved and ragged. On closer examination, 

 the stunted and injured leaves appeared dark-colored, or, perhaps, sooty- 

 black, in spots and irregular lines. The young twigs, too, presented a simi- 

 lar appearance, being blackened, and often distorted in growth. In some 

 localities, especially southward, pear trees suft'ered in the same way, but the 

 leaves more generally attained full size, however much they were discolored 

 and distorted. 



The fruit, too, of both these orchard trees was unusually badly injured by 

 what people call the "scab," The apples have been, in numerous instances,
