 Bellow color and the ocior of the fresh leaves. It

 standing. 



It was impossible to make a satisfactory, deter- 

 mination of the yield owing to several circumstances. 

 The first of these was a delay of a week--ten days 

 after cutting--bef ore the still was available. The 

 first run was interrupted "by a leak in the still
