result of his efforts, numerous American species of tumble 
bugs have been received and liberated on the large ranches, 
and several species of internal parasites, as well as several 
species of predators upon mealy bugs have also been received 
and liberated, or colonized for future liberation, as the cir- 
cumstances required. The following are noted under the sec- 
ond heading. All requests for advice or assistance in the con- 
trol of injurious insects have been attended to as far as pos- 
sible, and in doing so occasion has been taken to study the 
applicability of the spraying and dusting of various mixtures 
and compounds to the control of insect pests. Considerable 
data of value has thus been secured. Likewise, a study of 
the insect pests and diseases of the pineapple plant has been 
made, and in connection therewith an experiment has been 
conducted to determine the most suitable insecticide for the 
control of the pineapple mealy bug, scale, and red spider. A 
move has been made also, to secure relief from the worst in- 
festations by the introduction of parasitic and predaceosis 
insects. Scientific or popular articles based upon the studies 
mentioned have been published, or are in course of publication, 
and the insect collections and entomological library of the 
Board have been maintained and greatly added to. 
Plant Inspection. — The work performed by the Chief Plant 
Inspector and his assistants during the year consisted of: 
(1) The inspection of all fruits, plants and vegetables shipped 
from Honolulu to all ports of the other islands for the purpose 
of preventing the spread of any pest existing on Oahu to the 
adjacent islands ; (2) the inspection of all fruits, plants and 
vegetables coming into the Territory by mail, freight or bag- 
gage from foreign countries and the mainland of the United 
States, to prevent the introduction of pests and diseases liable 
to become injurious to the various agricultural industries of 
these islands ; and (3) the identification, tabulation, and pres- 
ervation of all pests and plant diseases intercepted in inspec- 
tion, and the care of all collections of injurious pests which 
vre taken in inspection, as well as material acquired by ex- 
change from foreign countries showing various pests to be 
guarded against. During the past fiscal year there arrived 
at Honolulu, Hilo and Kahului, the only ports of the Territory 
where fruits or vegetables enter directly and at which places 
local inspectors are stationed, 616 vessels. Of these, 391 car- 
ried vegetable matter consisting of 325,600 packages of fruits 
and vegetables and 3,524 packages of plants and seeds. Of 
this amount, 302 packages were fumigated on account of in- 
festation of various kinds or as a precaution ; 1 ,296 packages 
were burned on account of infestation or as contraband; and 
716 packages were returned to the original shipt>er as contra- 
band or unmailable. In addition to the regalar steamer^;, ^.11 
vessels calling for supplies and fuel are boarded on arrival at
