PREFACE. 
-- 
Before submitting the observations of the past season to 
the contributors to whose kind assistance I am indebted for the 
information, I beg to offer my best thanks for their courteous 
co-operation, and to request its continuance. I wish also to 
offer my thanks for the assistance cordially rendered by the 
press. 
It will be noticed that the observations have now been 
extended in some degree to insects affecting cattle and farm 
stock, and a slight corresponding alteration has been made in 
the title of the Beport. 
During the eight years in which our crop insects have been 
reported on, such full observation has been sent in of some of 
the regular yearly attacks that it seems to leave but little more 
to say with regard to these ; but there are some points which are 
shown constantly and plainly still to want attention as the very 
starting-points of a large part of our yearly attacks, and one of 
these is treatment of grass and clover-lea before breaking up. 
Half or more of the ravages of the Wireworm and Daddy Long- 
legs grubs arise from these being in the land before the new 
crop is put in, and any notes of treatment to prevent egg-laying, 
or of applications or treatment to destroy the grubs in breaking 
up the land, would be very acceptable, as tending to lessen one 
great source of loss. 
Warble Fly injury to our cattle, and Liver Fluke to our sheep, 
are two other important subjects. On the first I should be 
greatly obliged for any information and specimens; on the 
second, though I am not qualified to offer any advice relatively 
to the Fluke when in the liver of the sheep, yet as much might 
be done to lessen the amount of this disease by lessening the 
amount of the Marsh or Pond Snails, in which the Fluke spends 
the first part of its life, I should esteem it a favour to receive any
