found (as above) in Clover after Wheat. The points of fondness for 
damp localities, and also presence in Couch-grass would conjecturally 
bear on the large numbers seen in the grass at the hedge-sides, and 
the very few (practically the absence) in the permanent grass fit for 
mowings ; and the further point to which Mr. Swan wick draws atten¬ 
tion of it being his practice to sow his grass-seeds with the Wheat, 
and therefore the stubble not being destroyed, would be (as we see 
above) likely to act very strongly in increasing amount of attack. 
The great point of prevention of this Red Maggot is to give it no 
winter shelter, which is naturally at the roots of the Corn crops or of 
Couch (and possibly some other) grasses; artificially in large chaff- 
heaps. The chaff-heaps and the rubbish and dust from the threshing- 
machine can be easily managed; and in the fields a great deal of the 
Red Maggot might be got rid of by taking the cultivator through the 
land, and collecting and burning the stubble-roots. Removal* or 
even rough mowing, or “skinning” of rough grass by hedge-sides 
before flowering time, would also do much good.

The Report on Wireworm contributed in the previous year appears 
to leave little more to be said as to the methods of prevention or 
remedy of attack found to be practically serviceable; but in the 
following observations one or two points are continued then under 
experiment, and they refer, in two places, to the important matter of
