A408 QUEENSLAND AGRICULTURAL JOURNAL. [1 Dec., 1902. 
Questions arising in the administration of the Act have, however, from time 
been referred to me for consideration and report. Moreover, at the instance of 
individual inspectors, much time has been bestowed on the identification of injurious 
insects and in the ascertamment of the nature of plant disease. Also, on the action 
on both of specific disinfection processes. 
As a member of the Board of Advice regular attendance, when in Brisbane, has 
been bestowed on its periodical meetings, and an active part taken in its deliberations 
and in the formulation of its suggestions. 
In the report for 1909-1901 important experiments that had been conducted 
with reference to the disinfection of fruit by hydrocyanic acid gas were referred to, 
and the anticipation expressed therein, that there were grounds for concluding that in 
the near future the findings would find expression in the issue of amended regu- 
lations having reference to the fumigation of fruit for export, has been since 
realised in the issue of regulations of such a nature as is alluded to. And it is 
gratifying to learn that no complaint has come under notice respecting the condition of 
fruit that has undergone the fumigation treatment in accordance with their 
requirements, except in the case of some parcels treated at Maryborough during the 
early portion of the citrus harvest. And at Brisbane alone no less than 10,479 cases 
of fruit passed through the Departmental Chambers during the months of May and 
June alone. This fortunate issue is, however. no doubt principally due, not to a 
lessening in the amount of re-agents used, but to the rivaled meteorological 
conditions to which the fruit had been already subject prior to pein submitted to 
treatment: a conclusion borne out by the history of the Maryborough consignments 
that were reported to have experienced manifest injury. At the same time it bespeaks 
the care bestowed on the work by Mr. Inspector Liversee, on whom it devolved. 
Lisrary.—The additions to the library have been exclusively confined to a few 
works of periodical issue that have been purchased; and donations received from 
correspondents of the office, transmitting their gifts from almost all parts of the 
world. * * * * * * * * * % * %

CottEctions.—These have been augmented by a few purchases. 
Posuicarions.—The following is a list of the publications that have emanated 
from this office during the year, viz. :-— 
(1) “Some Obstacles to successful Sugar-cane Cultivation.” Queensland 
Agricultural Journal, Vol. LX, pp. 85-89, July, 1901. 
(2) “Entomology, Miscellaneous Notes.” | Op. cit. Vol. X., pp. 62-63, 
January, 1902. 
(3) “Vegetable Pathology. Grape Vine Anthracnose (Sphalacoloma ampelinum) 
and Grape Vine Coulure.” Op. cit. pp. 63, January, 1902. 
(4) “A Parasite of Sugar-cane Beetle Grubs ” (Dielis formosus, Guerin). Op. 
cit.. pp. 130-140, pl. [X. February, 1902. ; 
(5) “Grape Fruit-rots fa) Sun-scald and Bees; and, (b) Dematium fungus-

(6) “Maize Blight.” Op. cit. pp. 334-338. May, 1902. 
(7) “Foreign Insectivorous Birds: Importations effected and proposed.”

Norr.—The briefness of this enumeration is accounted for by the exactions on my time made 
by the ordinary duties of office as already set forth. 
ACKNOWLEDGMENTS.—That this office may have enriched to some slight degree 
the important sciences to which it ministers, and which direct its activities, may be 
inferred from the fact that in the most recent Annual Report (Jahresbericht tiber 
die, Neuerungen und Leistungen auf dem Crebiete des Planzenschutzes) of Dr. 
‘Hollrung, of Berlin, on current, investigations relating to plant diseases, no less than 
six distinct references were made to memoirs that have emanated therefrom. 
Again, this may aiso be inferred from the fact that in May, 1902, issue the 
famous Zeitschrift fur Pflanzen-Krankheiten, of Stuttgart, edited by the veteran 
yegetable-pathologist, Dr. Sorauer, an article of four pages, entitled “Schadigungen der 
Kultarpflanzen in Queensland,’ from the pen of Dr. L. Reh, is also devoted 
exclusively to references to them.
