The next paper, treating of the same insect, was presented by Mr.

THE PRESENT STATUS OF THE SAN JOSE SCALE IN MICHIGAN. 
By WALTER B. Barrows, Agricultural College, Michigan. 
So far as we have any knowledge, the San José scale first came to the 
notice of the State Experiment Station May 14, 1896, when it was found 
on a single fruit tree in Jackson, and the tree was destroyed soon after. 
The origin of the affected tree was not ascertained, and as no other oceur- 
rences were reported from the vicinity it was supposed that no further 
trouble would result. In December following, however, it became evi- 
dent from its invasion of the States adjoining Michigan on the south 
that our own State was in serious danger, and on application to the New 
Jersey nurserymen who were supposed to have sent out infested stock, 
a list of several hundred Michigan addresses was received by the hor- 
ticulturist of the station, and a circular letter describing the scale and 
its work was sent to each address. Comparatively few replies to this 
letter were received, but among them were some which indicated the 
presence of the scale, and further inquiries showed its presence in 
several places. 
During the winter many different parts of the State were visited in 
quest of the pest, but the severe weather, the lack of time, and espe- 
cially the number and extent of the suspected orchards, made anything 
like thorough inspection impossible. The scale was located in greater 
or less abundance at half a dozen widely separated points, and this 
number has been increased by as many more through correspondence 
and the transmission of specimens. At present the scale is positively 
known to have existed in the following counties, and in no case is there 
positive proof that it has,been entirely eradicated:

In Ottawa County the infested stock was received from New Jersey 
in the spring of 1890, and thus had been established almost seven \ciws 
before it came to the knowledge of any entomologist. During this time
