A little later specimens were received from Jefferson County, Ind., but 
here tbe owner of the affected orchard thinks he has exterminated the 
scale by burning all infested trees. 
Another new locality whicb 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 thorough 
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 
survived the treatment, however, was shown 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 will 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 meaus. He 
has, unaided, applied a rather expensivebut effective whale-oil soap win- 
ter wash to every suspected tree, and expresses himself as willing to 
wash the whole orchard once more if, upon 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 
comx)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 Experiment Station, 
Prof. O. Clute, has taken a lively interest in the matter, and inasmuch
