 surface, and the infested area is not too large for 

 application of this remedial measure, attacks might 

 be perfectly easily kept in check by utilising the habit 

 of the caterpillars of going down for the winter, and 

 l_ying in cocoons beneath the branches they have been 

 stripping of their leaves.
