SUMMARY OF DISTRIBUTION BY STATES. 25 
Jersey trees Mr. Emory had noticed their diseased condition, and had an 
employee go over the ones most affected with a -thick whale-oil soap 
of the consistency of molasses." This treatment was perfectly effectual. 
Examination of one of these trees showed that it was perfectly clean 
nearly three years after treatment. The owner of the orchard was 
rather prejudiced in favor of the whale oil-soap treatment, and a very 
strong wash was then given a young pear tree to further substantiate 
its efficacy. The good results shown by the old treatment and obtained 
in this new experiment led to the more careful work with soaps con- 
ducted by the Department at .Riverside, which ultimately established 
the superior merits of soap washes of proper strength as winter 
remedies. 
Riverside. — At Riverside the infested orchard is on the bank of the 
Potomac River, in Charles County, Md., on the place of Mr. E. Dows. 
and the fact of its infestation, as already described, came to our knowl- 
edge in March, 1894. The orchard covers about 20 acres, and consists 
chiefly of peach trees, with which, however, are intermixed some apple 
trees. The infested stock was received in 1887 from Xew Jersey, 
planted in the spring of 1888, and from this practically the entire orchard 
has been infested, many of the trees having already perished, including 
most of the original infested stock. 
When this point of occurrence was first discovered, the neighboring 
orchards were, as far as could be determined, entirely free from scale. 
In October of this year (1895), however, it was found that two vigorous 
young peach orchards a mile to the south, belonging respectively to Mr. 
Robert Marbury and Mr. Swan, were also infested in spots with the 
scale, together with a few peach trees on the river intermediate between 
the Dows farm and the orchards last mentioned. The stock of the 
latter orchards was obtained from a Virginia nursery, and the trees 
were unquestionably healthy when first received. The scale has evi- 
dently been carried to them by birds or insects from the Dows orchard. 
West River. — It was learned April 25, 1895, that some Japanese 
quinces received from a Xew Jersey nursery, and growing on the place 
of Mr. X. S. Chew, at West River. Anne Arundel County, were infested 
with the scale. 
Sharj)sburg. — This locality was brought to our notice by Mr. Joseph 
H. Cox, who sent specimens of diseased peach trees to Professor Rob- 
inson, of the Maryland Experiment Station, who submitted them to 
this office for determination December 2, is«>4. Mr. Coqnillett was 
sent to this locality March 15, 1895. The orchard was found to be 
situated 3 miles northwest of Sharpsburg. on the Potomac- River, and 
to contain 9£ acres of 4-year-old peach trees obtained from a nursery 
near Frederick, Md. The scale seems to have been introduced with 
a particular variety, which was planted in the center of the orchard, 
and from this point had spread more or less outward. 
An additional locality at Sharpsburg was brought to our attention
