intercepted, its whole organization thereby deranged, and decay 

 and death soon follows. The sap ascends from the roots to the 

 leaves, and is there elaborated and descends through similar 

 channels, and in its descent after elaboration, a portion of it is 

 assimilated with the tree, and increases its wood and growth, and 

 preserves its life. The eleven or seventeen ingredients which it 

 is said all, or most plants require to make them live and grow, 

 would not help the peach tree thus afflicted ; they would not any 

 of them touch the seat of the disease. Perhaps these or some of 

 them might have assisted ia producing the cause, that is, too sud- 

 den and rapid a growth of the tree, occasioning a superabund- 

 ance of juices, and thereby surcharging its sap vessels and mak- 

 ing them explode. It is not unlikely that every disease to which 

 the tree is subject, arises from some such eause, some maltreat- 

 ment in its culture, it may produce the yellows. We do know 

 that the tree in the middle and eastern states is and has been 

 forty or fifty years, short-lived, where it did not use to be so. 

 If any one could discover a remedy for this grievance he would 

 be conferring a great benefit on his fellow citizens, in increasing 

 largely their health and happiness, profit and comfort. 



Mr. Manice, of Long Island. — I know that the early harvest 

 apple which is accustomed to bear a crop only every second 

 year, is now made to bear fine crops every year. In some fruits 

 this constant production of fruit is found, and not at all with any 

 injury to the trees. An orange tree will give three crops a year. 



A member asks : How is it in forest trees ? 



Another replied : Hickory gives nuts only every second year. 



Professsor Mapes. — When they are mulched they bear every 

 year. Their own leaves covering the ground all about them, 

 does this. Single trees, where the leaves are blown away from 

 them, bear biennially. 



The Chairman gave an invitation to all the members to bring at 

 next meeting some of their best seeds, grafts and cuttings for ex- 

 change. Each may bring but one, but he may carry many away. 

 And besides, when brought by honorable citizens they are far 

 more reliable for quality.
