Reports of the Honorary Consultivg Entomologist. 325 
The very large numbers of the daddy longlegs which have 
been about during the autumn make it probable that great 
mischief will be done by the leather-jackets next spring, and 
it would be very desirable to point out that all the measures

which have been found practically useful to clear wireworm — 
in breaking up pastures and clover ley — would be as useful in 
getting rid of the daddy longlegs grub (that is, the " leather 
jacket," or "black grub"). These consist of heavy dressings 
of lime, gas-!ime, lime and salt, or alkali waste, to kill the 
surface insects and sheltering weeds, oi in gaining the same object 
by feeding cattle or sheep on the ground. 
Beet- and mangold-fly attack has been bad, and the only remedy 
when it is present appears to be

the application of dressings 
which will act at once to stimu- 
late growth ; but when attacks 
occur in drought, there is the 
difRculty of these not acting. I 
would submit that in the case 
of this attack, as with turnip- 
fly, autumn preparation, or such 
preparation of the land as would 
preserve the moisture of the soil, 
as well as give a rich ground and good tilth, is an important 
preventive, so as to run the plant rapidly on to a size of leaf, 
wiiich the maggot has less effect on.
