MINUTES SEPT. 



The Midfummer moot and the Midfum- 

 mer barking- time have always .daggered my 

 opinion relative to a uniform motion of the 

 fap, on Dr. Hales' principles ; nor have they, 

 I believe, ever been fairly accounted for ; but 

 remain an unanfwered argument in favour of 

 a circulation of the fap *. 



Being flruck with this year's ample (hoot, 

 I was led into a train of reflection upon this 

 interfiling fubjecl:. 



The fpr'mg run of the bark and the fpring 

 moot are the acknowledged confcquences of 

 the rife of the fap ; but how fimilar 6ffec~ts 

 Ihould take place about Midfummer, when an 

 extraordinary rife of fap cannot eaiily be 

 proved, may fecm difficult to explain. 



If, however, we conceive a regularly afcend- 

 ing ftream to commence on the approach of 

 fpring, and to continue rifing, uniformly, un- 

 til the wane of Autumn; and trace, with 

 clofe attention, the effects which muft neceffa- 

 rily be produced upon the tree by fuch a uni- 

 form rife of fap ; we ihall find them to be 

 exactly thofe which annually occur in nature : 

 namely, a fpring run of the bark, fucceeded 

 by a fpring ihoot, with leaves, &c. a Mid- 

 iummer run, with a fucceedmg fhoct, &rc.
