of the circulars sent out by them was secured. Nearly 1,000 letters 
were mailed, each inclosing a circular, each separately written on the 
typewriter, and signed by myself, in order to avoid any ••circular" 
look. A large number of replies was received, and guided by them I 
visited nearly 100 orchards, spending twenty-one days in the field, and 
examined many thousands of trees, covering very completely all the 
central and southern portion of the State. 
It is worthy of note that in not a single point north of New Bruns- 
wick has the scale spread, though I believe scaly trees have been set 
out; in fact, so far as I have been able to ascertain, it has jjropagated 
only south of the red shale which extends diagonally across the State 
from a point a little north of Perth Amboy in the east to Trenton in 
the west. That it will maintain itself north of this point, for a time at 
least, is proved by the fact that an orchard in Columbia County, N. Y.. 
is very thoroughly infested. Throughout New Jersey, south of the red 
shale, the scale is distributed here and there, but nowhere in sufficient 
numbers to spread from the orchard into which they were originally 
introduced. In fact, in many cases the trees are yet so small and the 
scales are comparatively so few that extermination will be an easy task. 
On the other hand, a considerable number of trees were found so badly 
infested that they were decidedly dangerous, and they were in all cases 
cut out and burned at my suggestion. 
I feel positive that no spread has yet been made in Xew Jersey except 
by means of nursery stock. I feel safe in saying that no further infested 
stock will be sent out from our nurseries. I am reasonably sure that 
all the growers that I have seen will adopt any measures suggested by 
me, and will get rid of the scales — in fact, I will make it my business 
to follow them up until they do it — and. finally. I see no reason vrhy it 
can not with us be completely stamped out. 
The history of the importation of the scale into Xew Jersey is the 
same for the two nurseries from which it has been distributed. In 
either 1886 or 1887, in their search for a Curculio-proof plum, their 
owners were advised that the Kelsey,' 1 an improved Japanese variety, 
grown in California, filled all requirements, and a lot of Kelsey trees 
was ordered from the San Jose district. In both cases the trees looked 
bad, grew very little, and after remaining in the ground for two years 
were, most of them, taken out and burned. Other trees had been 
grafted and budded from them, however, and from the appearance of 
the few remaining trees it is certain that this importation brought in 
the infection. Idaho pears have also been imported from the Pacific 
coast for several years past, and it is certain that many of them were 
also infested. At all events, a start was soon made, and in 1891 and 
1892 several blocks of young apple trees were badly infested — so badly, 
indeed, that many were not considered up to the standard, and were 
destroyed. Since that time few apples have been grown at these 
nurseries, and no distribution of the scale has been made on them.
