to be noted that : — 



In the uncobbed plants examined the percentage 

 amount of sucrose in the juice varied to a very great 

 extent as the crop approached maturity. 

 That the sucrose content of the juice was much more 

 uniform in the cobbed plants. 



That the average amount of sucrose in the juice of 

 stalks bearing cobs examined between April 2nd and 

 9th (excluding sweet corn ) was 8.2 per cent., and the 

 average amount in the juice of plants of the same 

 varieties cobbed on April 2nd and examined between 

 April 10th and 12th was 1 1.5 per cent., and that there- 

 fore in those plants from which the cobs had been 

 removed the amount of sucrose increased considerably 

 during the first eight or ten days after cobbing. 

 That the sweet corn variety gave the lowest results 

 per acre for sucrose. 



That in all cobbed plants examined between April 10th 

 and May 23rd (eight to fifty-one days after removal of 

 cobs), sweet corn excluded, the average sucrose content 

 of the juice was 12 per cent.
