nient station, observed that several small peach trees had just died, 

 and upon further inspection found the trunk and branches of each dead 

 tree well covered by scale insects. Twigs were taken to the laboratory 

 in Xew Haven, where they were given a more thorough examination. 

 The scale was suspected to be the San Jose, or pernicious scale, but 

 as no one at the station had ever seen that species, specimens were 

 submitted to Mr. M. V. Slingerland, of Cornell University, and to Dr. 

 L. O. Howard, of the Department of Agriculture, at Washington. Both 

 pronounced it A.peniiciosus. The writer visited Mr. Baub's orchard on 

 June 25, in company with Dr. Sturgis, and took notes regarding the 

 infested trees and their surroundings. The orchard was badly infested. 

 Fortunately, however, it was the only orchard in the immediate 

 locality, so that the conditions necessary for the rapid spread of the 

 insect were not at hand. Living scales were found upon about half 

 the trees, but there were also many dead scales which were about half 

 grown and had probably been killed the previous winter. Trees of the 

 orchard were obtained from the Pomona nurseries, Parry, N. J., dur- 

 ing the seasons of 1891, 1892, 1893, and 1894. The plantings of 1891 

 and 1892 were badly infested, and it was amongst these that the dead 

 trees were found. The stock of 1893 undoubtedly was infested when 

 planted, but was still vigorous, while the trees planted in the spring of 

 1891 appeared to be free from scale. Previous to this the owners of the 

 above-mentioned nurseries had instituted vigorous measures to rid 

 the stock of insect pests. Mr. Eaub destroyed immediately many of the 

 worst infested trees of his orchard, and applied whale-oil soap solution 

 to the other trees. This treatment was repeated the following April, 

 and gave good results. Early in the. spring of 1896 a bucket of u Den- 

 drolene" was sent to the station by its manufacturers, the Bowker Fer- 

 tilizer Company, of Boston, and Dr. Sturgis forwarded it to Mr. Eaub, 

 with the request that he give it a trial on some of his trees. Through 

 a mistake all trees of the orchard which were infested with scale were 

 coated with the substance about May 1. On June 1 Mr. Eaub wrote 

 that all of his trees were dying. A later examination proved that the 

 trees had been killed by the "Dendrolene," and by killing the trees the 

 scales were destroyed. 



As soon as it was learned that infested nursery stock had been sent 

 into Connecticut from Parry's nurseries, a letter was addressed to Mr. 

 Parry asking for a list of his Connecticut customers during the period 

 between 1890 and 1895, that we might the more readily learn of the 

 extent of the distribution of the scale in the State. Mr. Parry cour- 

 teously complied with our request, and sent us a list containing ninety- 

 two names. 



Circular letters were sent to these addresses calling attention to the 

 presence of the scale in Connecticut, and asking each owner to examine 

 his stock and report, a card for reply accompanying each circular. 

 Forty-three replies were received. Twenty-eight reported no scale, 

 while ten found indications of its presence.
