afcending at the under feclion of the branch, was greatly fu- 

 perior to its force in defcending at the upper fedion. 



MARCH 30. 



Thermometer, at noon, 50. j at midnight, 43. 

 THE eighth incifion bled ; but the ninth continued dry. The 



inverted branch (till bled freely at E. The under fections of 



the feven incifions on the branch B bled j but their upper fec- 



tions were as yet dry. 



OBS. 25. The ninth incifion ftill refufed to bleed, though the 

 heat of this day appeared fufficient to elevate the fap to that 

 height ; but between the eighth and ninth incilions, there 

 were two large young branches, which feem to have led off 

 the fap fafter than the old wood of the trunk. 



OBS. 26. From what has been noticed of the branches D and 

 B, we find, that a young branch bleeds fooner than an inci- 

 fion in the trunk, placed even below the infertion of the 

 branch. This evidently arifes from a quicker and more eafy 

 flow of the fap in young than in old wood; by which means, 

 the branch comes to be fooner replete with fap than the ad- 

 joining part of the ftem. 



MARC H 31. 

 Thermometer, at noon, 62. ; at midnight, 40. 



THE feventh incifion upon the trunk bled ; but thofe above 

 it were dry. The fedion of the inverted branch at E continued 

 to bleed. All the feven incifions upon the branch B were 

 dry. 



OBS. 27. When I found the thermometer fo much higher this 

 day than it had been at any time during the feafon, I went 

 out, expecting to find the tree bleeding at a greater height 

 than it had hitherto done : But in this I was difappointed ; 

 for all the incifions above the feventh, even the eighth and 

 ninth, which had formerly bled, were perfectly dry. This 



was
