stock. W’e a])pend, herewith, his report of work for the year 
just ended: 
During the past year, there have l>een some changes in onr methods of 
orchard and foreign inspection; that is, we arc now trying to locate such 
pests as .San Jose scale not only in onr nurseries, but in onr orchards. Onr 
appropriation docs not allow for very much of this work, l^nt during tiie 
last season, some little work was accomplished along these lines and the 
coming season we are planning to extend this work so as to (piite thor- 
oughly examine an area of several counties. This work will be reported 
daily to the office of the State Entomologist where all records will he kept 
on permanent file. In onr foreign inspection, we have found the best of 
co-operation in regard to care taken by greenhouse and nursery men. We 
have asked alwa 3 's that all packing l)e carefully collected and burned and 
have met with no opposition to this important ruling. In many cases it 
is expensive and inconvenient to go to a town out of the Twin Cities for 
each box of foreign stock shipped in and we have allowed the shipment to 
be unpacked and packing burned to await the final shipment in that locality 
or until we had more time for work. So far, we feel this is satisfactory for 
greenhouses, but of course for nursery stock wdiich comes in the spring, 
we would not care to try it. Stock from Holland and Belgium and France 
came in even greater abundance than it has in years past. The imported 
stock, as a rule, was in very good condition and but few pests — none of any 
great importance — were found. In several cases we found an abundance 
of aphids and of oyster shell scale; some fev/ other minor pests which were 
destroyed by dipping the dormant stock in tobacco solution. 
The inspection of foreign stock in the spring of the year was accom- 
plished, for the most part, by the Deputy Inspector, l)ut at certain times, 
when large shipments of stock arrived at several places at the same time, 
or an extremely heavy shipment at one place, hel]) was secured from experts 
in the Divisions of Plant Pathology, Horticulture, and Entomology. 
Through the courtesy of these men, we were aide to keep the inspection 
work up to date. 
During the earh^ part of the summer, an extended trip was taken to 
trace some few shipments of mountain ash which originally came frenn 
Michigan and on which we had evidence of the possildlity of San jese 
scale being present. In no case was the scale found on these shipments, 
although many of the trees had died and l)een destroyed, so it was im- 
possible to determine if scale had l)een present. 
The summer inspection of nurseries was hampered to some extent 
by the weather conditions in the early part of the season, 1)ut although 
we had about forty more places to visit this year than last year, the sum- 
mer work was completed so that it did not interfere with the inspection of 
imported foreign stock which came in this fall. The amount of imported 
stock from Euro]:)e is practically the same this year, l)ut it is coming in 
very late — in many cases due to slow transportation after it reached the 
port of New York; that is, on our own railroads. 
The coming year, the imported nursery stock to 1m planted out, of 
course, will be inspected, as in the past, and the summer work, we hope, 
will be greatly helped l)y the fact that provision was made for more ex- 
tensive field records and collections and closer co-operation with the vari- 
ous sections of the Division of Entomology. During the past year, only 
one nursery was found with nursery stock infested with San Jose scale. 
This stock had been imported from New York State and lined out. This 
nursery now has a modern fumigation liouse and fumigates all stock leaving 
the premises, besides thoroughly spraying with concentrated lime sulfur 
all trees near those which were found to be infested. This was the second 
nursery m which San Jose scale has l)een found in the last two seasons 
and provisions have been made in both cases to see that the scale was 
destroyed and all stock fumigated 1)efore leaving the infested nursery. In 
both these cases, the stock came from another state and was lined out in 
the nursery where it was later found. We have been trying to gradually 
build up the inspection work, so as not only to eliminate the possibility of
