only slightly cloudy and had all run the day it was concentrated. 

 The sirup contained 95.27% sucrose and 2.76% invert sugar. 

 The color was 8, flavor 3, and score 700; depreciation from con- 

 trol (number 21), color 5, flavor 2, and score 250. Deprecia- 

 tion from first run control, color 2, flavor 2, and score 175. 



23. Number 23 was made from sour sap obtained April 

 12 and held 24 hours. The sirup contained 92.56% sucrose 

 and 3-55% invert sugar. The color was 14, flavor 3, and score 

 550; depreciation from control (number 24), color 7, flavor 2. 

 and score 300. Depreciation from first run control, color 8, 

 flavor 2, and score 325. 



24. Number 24 was made from sap obtained at the same 

 time and from the same tree as that for number 23. It was 

 drawn from a fresh tap, but was held for twenty-four hours 

 before concentration. The sirup contained 96.02%' sucrose and 

 0.61% invert sugar. The color was 7, flavor 1. and score 850.

25. Number 25 was made from sour sap which flowed 



April 16. The sirup contained 94.05' r sucrose and 3.13'- 

 invert sugar. The color was 14, flavor 3, and score 550: de- 

 preciation from control (number 26), color 9, flavor 2, and score 

 350. Depreciation from first run control, color 8, flavor 2, and 

 score 325. 



26. Number 26 was obtained from the same tree as number 

 25 and at the same time, but from a fresh tap-hole. The samples 

 were concentrated the same day they flowed. The sirup con- 

 tained 96.42% sucrose and 0.5 \' < invert sugar. The color was 

 5, flavor 1, and score 900. The color was one grade superior to 

 the first run control, the flavor equal, and the total score 2^ 

 points higher. 



The results of this single season's experiments taken alone 

 would seem to indicate that the color and flavor of sirup are 

 not impaired by physiological changes in the tree occurring dur- 

 ing the sugar season. It is important to note, however, that
