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

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

 California scale, were traceable to New Jersey nurseries which were, 

 in all probability, still serving as distributing centers for the distri- 

 bution of the pest over nearly all the country, a Circular was pre- 

 pared by Mr. Howard, Chief of the Division of Entomology, U. S. 

 Dapt. Agricul., describing and figuring the scale and warning fruit- 

 growers of its exceeding dangerous character, which was distributed 

 in the first week of April (1894) to all Eastern agricultural news- 

 papers and to nearly 12,000 Eastern fruit-growers whose addresses 

 were obtained from the pomologist of the department. This circu- 

 lar, — with its excellent illustrations*, description of its appearance, 

 explanation of its manner of spreading, 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 the 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 S. Eastern 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 direc- 

 tion 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 few infested pear trees that had 

 been bought from the New Jersey nurseries in 1890, had all been 

 killed 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. Those were taken up and burned, and no more of 

 the insects were discoverable by careful search. (A second infesta- 

 tion has since been discovered at North Madison — See J?ural New 

 Yorker, liv, p. 87.)
