A little later specimens were received from Jeftersoii County, Ind., but 

 here the owner of the aftected orchard thinks he has exterminated tbe 

 scale by burning all infested trees. 



Another new locality which has been given us by Prof. W. B, Alwood, 

 is City Point, Prince George's County, Va. We have not seen speci- 

 mens from this locality, but Professor Alwood's determination must be 

 considered authoritative. 



The last new locality is Bristol, Pa. At this point the scale was 

 introduced upon a dozen Japan plum trees purchased three years ago 

 from a New Jersey nurseryman. It has spread to a short row of pears 

 on the one side and to a row of plums on the other — perhaps thirty trees 

 in all. The owner has washed with whale oil soap and kerosene emul- 

 sion, but has been advised, in view of the small number of trees 

 affected, to cut them all down and burn them. 



WORK WHICH HAS BEEN DONE IN THE OLDER LOCALITIES. 



We have already reported the apparent success of the thorongh 

 treatment with hydrocyanic acid gas, which was given to the orchard 

 of Dr. C. H. Hedges, at Charlottesville, Va., in March last, under the 

 immediate and skilled supervision of Mr. D. W. Coquillett. The opera- 

 tion was as thorough as it could be made. That a few of the insects 

 snrvived the treatment, however, was sho\yn by the receipt of living 

 specimens late in the fall from Dr. Hedges, The State Board of Agri- 

 culture is informed concerning this condition of affairs, and we learn 

 from Hon. Thomas Whitehead, Commissioner of Agriculture, that the 

 Board has made an appropriation for the purpose of conducting a final 

 campaign, which Avill be instituted before spring. Moreover, the ento- 

 mologist of the State Agricultural Station, Prof. W. B. Alwood, is 

 greatly interested in the matter, and is giving it his earnest attention. 



At the old locality in Kent county, Md., it is most fortunate for the 

 neighboring fruit-growers that the owner of the infested orchard is an 

 exceptionally able and energetic man, as well as a man of means. He 

 has, unaided, applied a rather expensive but effective whale-oil soap win- 

 ter wash to every suspected tree, and expresses himself as willing to 

 wash the whole orchard once more if, u])on expert examination, it is 

 found that any scales remain alive. 



In late October we visited personally the infested locality in Union 

 county, Pa., and found the scale restricted to a very small orchard of 

 comi)aratively young trees, with no other orchards within several miles. 

 The owner is Dr. Geo. G. Groff, of Bucknell College, who is not only 

 willing but anxious to exterminate the insect, at no matter how great 

 trouble and expense. He has been washing his trees with undiluted 

 kerosene emulsion. 



The Florida outbreak, it will be remembered, was a very extensive 

 and dangerous one. The Director of the State Exi>eriment Station, 

 Prof. O. Clute, has taken a lively interest in the matter, and inasmuch
