GOOSEBERRY AND CURRANT SAWFLY. 45 
The fact of the eggs being found in the crannies of rough bark 
during winter, and of the mites similarly sheltering during the season 
of their fully-developed presence, points directly to the advantage of 
scraping off and getting rid of rough bark as far as can be managed, 
and also of removing gnarled and rough-barked boughs; also, and very 
particularly, of syringing and running soft-soap washes down the stems 
so as to fill the crannies and angles of the branches, and thus choke 
up the lurking-places, and stifle the mites within them. 
To the above should be added a note of the vital importance, if the 
infestation is to be got rid of, of commencing remedial operations as 
soon as ever it appears in the spring. If a little keg of whatever mix- 
ture the owner prefers is kept at hand on grounds where there is reason 
to suppose the attack may appear, then at the first siyns (it may even 
be as early as the middle of February) the remedy can be applied 
forthwith, and it may be hoped a cure made. But if instead advice 
has to be sought, and the application to be written for, days are lost, 
in which the injurious pest is hatching out by hundreds or thousands, 
and not only doing present mischief, but establishing itself to lay the 
foundation of further presence,

Gooseberry Sawfly needs some reference again for several reasons, 
one of these being the great amount, and also the destructive nature 
of its attacks in various places, notwithstanding the severe cold of the 
latter part of the winter. With some of our injurious insects it may 
be difficult to be certain whether or not especially great cold reached
