THE amateur's GREENHOUSE 



SPECIMEN PYRAMID POMPON 



About the middle of 

 June stop them all 

 over. At the end of 

 September put them 

 in 4S's and shut them 

 up in a close warm 

 house and keep them 

 well syriuged. After 

 a week of this treat- 

 ment give them air 

 by degrees, and as 

 they come into flower 

 take them to the 

 conservatory. They 

 ought to be compact, 

 round-headed bushes, 

 completely covered 

 with flowers. 



The only insect 

 that seriously injures 

 the chrysanthemum 

 is the celery fly (Te- 

 pJiritis onojjordinis). 

 The maggot of this 

 fly burrows within 

 the leaf of the . plaut 

 and causes, first, a 

 pellucid pellicle, and 

 subsequently the 

 death of the leaf The 

 cultivator must occa- 

 sionally make search 

 for the maggot and 

 destroy it by pressing 

 the pellicle between 

 finger and thumb. To 

 remove it from the 

 leaf is impossible, as 

 it occupies the sub- 

 stance between the 

 upper and under sur- 

 faces.
