PREFACE. 
qualified hands of Dr. W. Dream, the course of instruction was 
throughout based on scientific principles, yet the practical appli¬ 
cations of the subject were constantly kept in view. The requisite 
broad generalisations not being brought forward at first, but 
gradually worked up to and placed clearly before the agricultural 
students as the facts on which they were based accumulated, a 
trustworthy foundation was thus thoroughly impressed on the 
hearers for future work. 
As in former reports it is my duty to offer my grateful thanks 
for important help afforded me in the past year’s work. To our 
own agricultural press I have always to offer my thanks for 
valuable co-operation, and I have likewise gratefully to acknow¬ 
ledge the liberal and unceasing donations of successive publi¬ 
cations with which I am favoured from Canada and various of 
our own Colonies, and likewise from the Dept, of Agriculture and 
Experimental Stations of the United States of America, which 
thus enable me to have at hand notes of the very latest advance 
in details bearing on prevention of insect crop and fruit pests. 
To some of my kind and skilled fellow-workers my thanks are 
most especially due. Amongst them to Mr. J. Fletcher, the 
Dominion Entomologist of Canada, for great help given by his 
sound and experienced advice regarding application of insecticides 
for orchard use, and especially of Paris-green. To Dr. J. Ritzema 
Bos, Prof, of Zoology at the State Agricultural College, Wagen- 
ingen, Netherlands, I am always indebted for his assistance with 
regard to identification, and also many other serviceable points 
regarding the history of nematoid worms, popularly known as 
Eelworms, which play an important part amongst the microscopic 
pests of some of our chief crops. 
To Mr. Frazer S. Crawford, of Adelaide, S. Australia, whose 
sound and well-skilled work was so serviceable in his own Colony 
and so well and so widely known, my tribute of yearly thanks is 
now (with the regret for his loss shared by his many friends) a 
tribute also of respect to the memory of an earnest and thoroughly 
true worker who has passed to his rest. His careful observations, 
the zeal for the public good with which he w T as ever on the alert 
to prevent establishment of dangerous infestations in the Colony, 
the hearty courtesy and open-mindedness with which all points 
under discussion were conducted with the co-operators with 
whom he was in correspondence at home or abroad, make 
his loss cause of great regret to his colleagues and friends; 
and with a grateful remembrance of many years’ unfailing 
assistance and co-operation, I desire to add my tribute of deep 
respect to his memory. 
In the following Report, I have as far as possible mentioned 
the names of my co-operators with the subjects under con¬ 
sideration, but I have especially to acknowledge with many
