INSECTS^ REMARKS THEREON, WITH INSTRUC- 

 TIONS HOW TO PREVENT THEM FROM BEING 

 INJURIOUS. 



Par. 21. Pines, like other plants, are liable 

 to be infested with small insects of several kinds, 

 and are frequently, if not attended to in due 

 time, very injurious, causing them to become 

 sickly, and in such a stunted state that neither 

 the plants or fruit make scarcely any progress ; 

 some only attack the leaves, but others will in- 

 fest the plants all over, even down to the roots ; 

 the insects are generally very diminutive, some 

 appearing like dust, and barely visible, and 

 some resembling small scales, while others ap- 

 pear like small bugs ; if these are not attended 

 to when they first make their appearance, they 

 will increase very fast, and soon spread over the 

 whole of the plants ; it will therefore be neces- 

 sary to use every means possible to destroy them 

 on their first appearance in the pinery. 



Various causes have been assigned for the 

 pinery becoming foul ; some will say the plants 

 were diseased when brought from another house, 

 thereby laying the blame on the former grower;
