form his habitation. As soon as such leaves are 

 perceived — and every morning the trees should 

 be examined — these glued leaves should be 

 squeezed between finger and thumb so as to crush 

 him effectually, after which the leaf may be cut

There is also the rose gi'ub to be guarded

 caterpillar : he eats into the young and succulent 

 shoot, and must be carefully sought for ; his small 

 entrance perforated in the young summer shoot of 

 the rose may sometimes be seen ; he should be at

 but this, for if the parent moths are prevented 

 laying their eggs in holes, they will find crevices 

 small but convenient. Number four of our ene- 

 mies will make our list complete, at least as far 

 as we know — but there may be hidden foes. 



Our present subject is the larva of the saw-fly ;

 The rose cultivator, if he sees some leaves veined 

 with semi-transparent veins, must at once be on
