of the plant, maturity could be hastened. With this object in view, 



three lots of plants were treated accordingly as soon as the heads 



had commenced to form and corresponding - lots were grown as cheeks. 



The results, so far as represented by figures, are tabulated below.

The figures relative to the point in question reveal nothing from 

 which Ave can infer that the operation has any influence upon the 

 maturity of the heads. 



By examining' the table, however, it can readily be seen that the 

 operation was not without its effects. 



In next to the last column is found the percentage of plants from 

 each lot which failed to form heads. Of the first variety, every 

 check plant developed a head, while of the treated plants one-third 

 failed to head; of the second variety, nearly the same proportion 

 failed; while of the third variety, over one-half of the treated plants 

 gave similar results, as did also about 17 per cent, of the check plants, 

 making nearly the same difference between the percentage of plants 

 failing to head in each comparison. 



Again, the size of the head was greatly decreased by the treat- 

 ment. The last column gives the relative weights of average heads. 

 Tn two instances the average weight of the treated plants was less 

 than one-half and in one case but little more than one-half that of 

 the heads from the untreated plants. 



Another result of tying up the outer leaves, which was even more 

 noticeable than any yet mentioned, as the plants were growing in
