ing of the buds; while other buds have the stipules of 

 the leaves as bud-scales j these remain on the twigs for 

 a time in the Tulip-tree, and drop immediately in the 

 Magnolia. 



FORMS OF BUDS. The size of buds varies greatly, as 

 before stated, but this difference in size is no more marked 

 than the difference in form. There is no better way to rec- 



ognize a Beech at 

 any time of the 

 year than by its 

 very long, slen- 

 der, and sharp- 

 pom ted buds. The 

 obovate and al- 

 most stalked buds 

 of the Alders are 

 also very conspic- 

 uous and pecu- 

 liar. IntheBalsam 

 Poplar the buds 

 are large, sharp- 

 pointed, and gum- 

 my ; in the Ailan- 

 thus they cannot 

 be seen. 



All the things 

 that might be 

 learned from a 

 small winter twig cannot be shown in an engraving, but 

 the figures here given illustrate some of the facts easily 

 determined from such specimens. The first twig (Ash) 

 had opposite leaves and is 3 years old (the end of each 

 year's growth is marked by dotted lines on all the figures) 5 

 the year before last it had 6 leaves on the middle portion ; 

 last year it had 8 leaves on the end portion and 12 on the 

 side shoots of the middle portion. The buds near the
