52 PBANTOM FLOWERS. 



weeks to macerate, and has a strong fibre. The leaves 

 of this tree present much variety of shape, and the 

 sizes of those which are matured vary from half an 

 inch to four inches in length. They may be gathered 

 as early as the 1st of June, and generally remain free 

 from spots until September. Avoid the foliage of the 

 suckers, which are frequently found growing vigorously 

 around the parent tree, as the fibres of such leaves 

 are too weak and tender for our purpose. They wiU 

 lose their stems by maceration, but these may be 

 replaced, as directed in a previous chapter. 



Aspen Poplak (^Popuhts tremula). 



The leaf of this tree is larger than that of the pre- 

 ceding, and is also more delicate. It may be gathered 

 in June or July, and will require about a month to 

 macerate. Great care will be necessary in handling 

 them. 



Tulip Poplar {Liriodendron tuUpifera). 

 LoMBABDT PoPLAE (JPopulus pyramidalis) . 



Both these may be gathered early in sunmier, and 

 should be treated like the Aspen Poplar.
