influence in winter; or would destroy them by chemical manures 
injurious to insect life but not strong enough to hurt the root-fibres, 
are useful, and lime or (in quite small quantity) gas-lime of course 
suggest themselves, but it might be well to try nitrate of soda. Kainite 
at a rate of over half a ton an acre has been found useful in U.S.A. 
experiment on infested Pear orchard land in destroying Pear Midge 
maggot in the ground, and though the maggot of the Apple Sawfly is 
larger, and also is protected by a cocoon, still experiment as to the 
effect of the kainite would be worth while. 
Many other preventive measures may be serviceably used with 
regard to both of the attacks, such as scalding baskets in which 
infested fruit has been transmitted, hand-picking the Sawflies when 
in reach, as when settling on the blossoms of espalier Apple trees; but 
these will be found in the papers on the respective attacks, to which 
reference is given in the foot-note on page 2. But the above condensed 
notes of the main points of distinction in habits and treatment on 
which preventive measures chiefly rest are given together as shortly 
and plainly as possible in order that growers troubled by ‘‘maggotty”’ 
Apples may be able to have the information at hand without further 
trouble in reference.
