season in Florida, although extermination [from the pecuHar condition

Discovered in other States. — In consideration of the discovery that 

 some at least of the above-noticed infestations of this pernicious Califor- 

 nia scale, were traceable to New Jersey nurseries which were, in all 

 probability, still serving as distributing centers for the distribution of the 

 pest over nearly all the country, a circular was prepared by Mr. 

 Howard, describing and figuring the scale and warning fruit-growers 

 of its exceeding dangerous character, which was distributed m the first 

 week of April (1894) to all eastern agricultural newspapers and to nearly 

 12,000 eastern fruit-growers whose addresses were obtained from the 

 pomologist of the Department. This circular — with its excellent illustra- 

 tions,* description of its appearance, explanation of the manner of spread- 

 ing of the insect, and the best remedies for it — as might naturally be 

 expected, excited much interest and alarm. Scale insects of many kinds 

 -as well as insects belonging to other groups, were sent to the Department 

 with the inquiry if they were the San Jose scale. 



As a result of the distribution of this circular, the following additional 

 localities were ascertained : 



Neavitt and Chestertown in Maryland ; Bartle, Indiana ; many points 

 in New Jersey; Atglen and Lewisburg, in Southeastern and Central 

 Pennsylvania. It was also received from Middletown, Idaho, and from 

 British Columbia. 



Referring to the above attacks, Mr. Howard gives encouraging 

 reports: The orchard of 7,000 trees in Atglen, Pa., under direction of 

 Dr. J. B. Smith, Entomologist at Rutgers College, New Jersey, had been 

 treated three times at intervals of ten days, with kerosene emulsion, with 

 absolute success. 



At the Lewisburg locality, the i&'N infested pear trees that had been 

 bought of the New Jersey nurseries in 1890, had all been kiiJed but 

 one. Other trees to which the scale had .spread were being treated by 

 the owner with every prospect of extermination. 



At Bartle, Indiana, two young apple trees from New Jersey were 

 infested. These were taken up and burned, and no more of the insects 

 were discoverable by careful search. (A second infestation has since 

 been discovered at North Madison — see Rural New Yorker, liv, p. 87). 



At Neavnt, Md., a lo-acre orchard of peach trees was b.idly infested 

 — nearly every tree was languishing from the attack. Many had been
