entire outfit of pumps aud spraying nozzles of the most approved pat- 
tern, and a skilled man was also to be sent there, who should remain 
in Walton County as long as his services are needed. The fruit-growers 
are to furnish materials and men, and a concerted effort will be made 
to go over all the infested trees in the district and make five or six 
applications of resin wash at intervals of about ten days. If these 
sprayings are carried out by an expert as promised, and if the operative 
is fortunate enough to hit upon a period of dry weather, there is every 
reason to suppose that the nuisance will have been abated by the close 
of the season in Florida, although extermination may not be found pos- 
sible. If, however, the spraying is done during a comparatively rainy 
season there will be reason to regret that the kerosene emulsion was 
not used. Mr. Hubbard made further arrangements with Mr. Mellish 
to forward specimens to Washington at intervals of a week, so that the 
rate of development in Florida may be compared with the rate of devel- 
opment at the North, and details of this character I hope to publish at 
the close of the year. 
In March, immediately upon the determination of the insects from 
Eiverside. Md., as the San Jose scale, upon the receipt of the same 
species from Florida, and upon learning that, in the former case at least, 
the stock was in all probability purchased from a large Eastern nursery 
as long ago as 1887, I prepared a circular of warning and distributed 
it the first week in April to all Eastern agricultural newspapers and to 
nearly 12,000 Eastern fruit-growers, whose addresses I obtained through 
the kindness of Mr. S. B. Heiges, pomologist of the Department. The 
circular gave carefully drawn illustrations of the insect in its different 
stages, described its appearance, explained how it spreads, gave the 
known remedies, and urged upon fruit-growers the great importance of 
examining their orchards at once and sending specimens of suspected 
scales to the Department. 
As the result; of this widespread distribution and the wide dissemina- 
tion of the warning by the newspapers, the division was for some weeks 
almost overwhelmed with packages containing scale insects of all kinds, 
from all sorts of plants, and from all parts of the country. Not only 
were scale insects received, but species belonging to many other groups, 
all the senders wishing to know if these were not the San Jose scale. 
The bark lice most abundantly received were the scurfy bark-louse, 
Chionaspis furfurus, and the common oyster-shell bark louse of the apple, 
Mytilaspis pomorum. I had previously supposed that every apple- 
grower knew this latter species, but this experience indicated a greater 
lack of familarity with the commonest forms than I had suspected. 
As a result of issuing the circular, the following new localities for the 
scale were ascertained : 
Neavitt, Talbot County, Md. ; Chestertown, Kent County, Md. ; Bartle, 
Washington County, Ind. ; many points in New Jersey ; Atglen, Chester 
County, Pa. 5 Lewisburg, Union County, Pa. Farther west the scale
