prominent series of veinlets run in a diagonal di- 

 rection, but irregularly, across tlie rough parallels 

 of tissue formed by the branch veins, and the thick, 

 soft substance of the leaf is further traversed, 

 between these prominent veinlets, by a close net- 

 work of venules. 



The normal hue of the foliage of the Wayfaring 

 Tree is a dull, deep green. At the commence-

 orange, yellow and red, but the yellow is ordi- 

 narily of a deep tint approaching orange. Some- 

 times the deep green hue turns uniformly to a

 The autumnal change is sometimes indicated 

 by patches of orange that, bright in the centre, 

 become gradually merged and finally lost in the 

 surrounding green. At other times a reddish 

 orange tint is given to the tissue and, if minutely 

 examined with the aid of a glass, it will be 

 seen that the effect is due to the presence of 

 small spots of red in the midst of slightly larger
