ISO HORTICULTURAL TOUE. 



particularly turned his attention to the structure of the 

 buds of fruit-trees, and has drawn some conclusions consi- 

 derably at variance with received opinions. He denies the 

 propriety of the distinction usually made of wood-buds and 

 flower-buds; but states, that, in the peach-tree, for exam- 

 ple, each leaf produces a bud at its axilla or base ; this bud 

 soon becomes triple, the two outer proving flower-buds, and 

 the middle one a leaf or wood bud. When this central 

 bud happens to be favourably placed, it sometimes de- 

 velopes itself indefinitely, and produces the anomaly of a 

 gourmand or robber. He has also announced, that the 

 embryo flowers of peaches, apricots, pears and apples are 

 palpably formed as early as midsummer of the year pre- 

 ceding that in which they are unfolded and produce fruit. 

 He asserts, that the branches of a mature tree produce re- 

 gularly every season an equal average quantity of embryo 

 flower-buds ; and that if these fail to be duly developed, it 

 must be owing to the low temperature to which they are 

 subsequently exposed, during the winter, or early in the 

 following spring. If he be correct in these observations 

 (and I am not aware of their having been controverted by 

 any accurate observer), the affording protection to such 

 fruit-trees, in the early spring months, acquires additional 

 importance. 



In the Nursery', there are a good many beds or lines of 

 seedling forest-trees ; considerable collections of young fruit- 

 trees, budded or grafted ; and a few of these, raised from 

 seed. Some large trees deserve notice, as remarkably fine 

 specimens of their respective kinds. Fraxinus simplicifo- 

 lia (here called monophylla), which originated in England, 

 hi , attained a large size. Ulmus fulva and crenata are 

 li.uidsome healthy trees. The Black Walnut of Ame- 

 rica, Juglans nigra, forms a lofty spreading tree. Gledit- 

 < hfa triacantlvos is about 30 feet high; and the newly in-
