Rostiezer, "best." Tatnall's Harvest, scarcely good. Beurre d'Amanlis, 

 fine specimens. Limon, "very good." 



From Robert Buist — Twelve varieties of pears and two of apples. The 

 specimens were beautiful, but not sufficiently mature to test their quality. 

 They comprised the following kinds : Pears — Andrews, Bartlett, Belle de 

 Bruxelles, Beurr6 Goubault, Capiaumont, Collins, Crassane, Doyenn6 

 Defais, Flemish Beauty, Julienne, and two unknown. Apples — Irish Cod- 

 lin and Rambour d'Ete. 



From Samuel Ott — Two varieties of plums and three of pears : — 



1. A Seedling Plum, raised by John Cope, of Southwark. Large ; an 

 inch and three-quarters long by one and a half broad ; long oval ; dark 

 purple ; stem three-fourths of an inch long, slender ; flesh not very juicy, 

 free from the stone ; flavor acid ; quality " good " for culinary purposes. 



2. A cling variety of the Red Magnum Bonum : very large ; oval ; purple ; 

 stem five-eighths of an inch long by one-twelfth thick ; quality " good." 



3. The Julienne Pear. — Fine specimens. 



4. The Tyson. — Handsome specimens ; quality " best." 



5. The Ott. — This is the fifth consecutive year that we have had an op- 

 portunity of testing the quality of this fine Pennsylvania fruit, which we 

 regard as the most delicious of all summer pears. 



Special Report of the Entomological Committee. August 15th, 

 1853. To the President of the Penna. Hort. Society : — 



The committee on entomology respectfully report, that their attention 

 has recently been directed to several insects, of which specimens, in various 

 stages of transformation, were received from members of the society. 



1. A species of coccus, or scale insect, of the apple tree; a noxious 

 bark louse, which injures the tree by sucking the juices from the branches 

 to which it is permanently attached. They are of a brown color, about 

 one-tenth of an inch in length, of an oblong oval form, and gregarious in 

 their habits. Where they are crowded together in great numbers, on the 

 limbs and branches, as is often the case, the growth of the tree is materially 

 impaired, and its life endangered. Dr. T. W. Harris, in his able " Report 

 on the Insects of Massachusetts injurious to vegetation," recommends, as 

 the best remedy for its destruction, " a wash made of two parts of soft soap 

 and eight of water, with which is to be mixed lime enough to bring it to the 

 consistence of thick whitewash." This application is to be put on with a 

 brush, to the limbs aflfected, " in the early part of June, when the insects 

 are young and tender." We have also used, with entire sucess, in the 

 winter, the whale oil soap, applied with a hard brush. 



2. Carpocapsa Pomonella, or apple moth. This is the insect which dis- 

 figures so many of our apples, and causes such numbers of them to fall 

 prematurely from the tree. Mr. Ewens, a member of our society, in passing 

 through his orchard, pulled up a sod of grass and laid it in tlie crotch of an 

 apple tree. Subsequently, he found it to be full of cocoons, which proved 

 to belong to the insect in question. In this case, the apple worms, as is 

 usual with them, had left the fruit, after they had attained their full larval 

 growth, (some of them whilst it was on the tree, and others after it had 

 fallen,) to take refuge in the crevices of the trunk. But finding a con-
