considerable difference existed in their relative feeding 

 values in favour of the roots of the untouched plants, as 

 will be seen in the following tabulated statement : 



Another experimental trial, carried on last season by 

 Professor Buckman, 1 gave similar results. In April last 

 two experimental plots were sown with Yellow Globe 

 mangolds, without manure. The after cultivation was 

 carried on in the usual manner ; and in August the one 

 which was apparently the most vigorous lot had the large 

 outer leaves stripped off each plant, which operation was 

 repeated in September, and again in October; the other 

 lot pursued their growth untouched. They were both 

 lifted at the end of October. The roots, trimmed and 

 weighed, gave the following results:
