126. Number 126 was obtained from the same tree ami 

 at the same time as number 125. but from a fresh tap-hole. The 

 sirup contained 94.46% sucrose and 0.31% invert sugar. The 

 color was 6, flavor 5. and score 475 : depreciation from first 

 run control, color 3, flavor 3, and score 425. 



127. Number 127 was made from sour sap obtained April 



27. The sirup contained 87.41 '< sucrose and 4-59 r ^ invert 

 sugar. The color was 15, flavor 6. and score 150: depreciation 

 from control (number 128), color 11. flavor I, and score 375: 

 depreciation from first run control, color 12, flavor 4, and score 



750- 



128. Number 128 was made from sap obtained from the 



same tree at the same time a- that for 127 but from a fresh 

 tap-hole. The sirup contained 94.21' , sucrose and 0.31$ invert 

 sugar. The color was 4. flavor 5. and score 525: depreciation 

 from first run control, color 1. flavor 3, and score 375. 



129. Number 129 was obtained from a fresh tap-hole April 



28. It contained 95.34' < sucrose and 0.12', invert sugar. The 

 color was 5. flavor 5. and -core 500: depreciation from first 

 run control, color 2, flavor 3. and score 400. 



130. Number 130 was made from sap obtained from the 

 same tree and at the same time as that for 129, but from the 

 sour tap-hole. It contained 93.80', sucrose and 1.34'' invert 

 sugar. The color was 12, flavor 6, and score 225: depreciation 

 from control (number 129), color 7, flavor 1. and score 2jy. 

 depreciation from first run control, color g, flavor 4. and score 



The results of this series of experiments confirm those 

 obtained the previous year, indicating that, accompanying the 

 resumption of vegetative activity in the tree, there is a change 

 in sap which makes it impossible thereafter to produce sirups 

 of superior flavor.
