DIVISION OF PLANT INSPECTION 
ANNUAL REPORT FOR CALENDAR YEAR 1921 
December 31, 1921. 
Board of Commissioners of Agriculture and Forestry, 
Honolulu, T. H. 
Gentlemen: I herewith submit for your kind consideration a brief 
report covering the activities of the Division of Plant Inspection during 
the calendar year 1921. 
The work performed by the Statf consisted of the usual work at- 
tendant on inspection of, plants and plant products from outside this 
Territory as well as the inspection of domestic produce for inter island 
shipments. 
The staff of the office consisted of the same personnel as reported on 
December 31, 1920. 
EQUIPMENT 
The equipment remains the same as last year except for a few small 
improvements. We have added a safety door or screened entrance to 
the quarantine room. This was found necessary as we found from ex- 
perience that some shipments of seeds and plants arriving in cases, when 
opened, had insects on the wing ready to escape. With the safety door 
all such escapes cannot reach the open and the whole quarantine room 
can be tightly closed and fumigated. We have also equipped a small 
developing room out of one of the old fumigating units which we had 
on Pier No. 10. We find it very useful and a good addition to our plant 
as it enables us to photograph many interesting captures thus adding 
valuable collections not only in specimens but in photos which exempli- 
fy the important work we are doing. 
HILO PLANT FUMIGATION BUILDING 
On September 1, the fumigation unit w^hich was to have been built 
at Hilo in 1920, was completed. It consists of a concrete fumigation 
vault, 20 X 20 floor space and 10 feet ceiling height, a 10 x 10 foot 
office of T. and G. lumber and a 10 x 10 shed in the rear office under 
which is stored a 6 x; 8 x 8 fumigating box and which will be used 
for small infested shipments as in the past. Into the large concrete 
vault can be placed from 1600 to 1800 bags of rice or other cereals. 
This Division is now in a position to handle any infested shipments ar- 
riving at Hilo and will give greater protection to the big island.
