XXXIV PREFACE, &C. 



a few bunches were cut and made into sugar at the same time 

 the experiment was made with the white canes. The report 

 made to me of them was, that they yielded a great deal of 

 juice, which seemed richer than that of the others, but the 

 sugar was strongly tinged with the colour of the rind ; and it 

 was observed, that upon the expression of them at the mill, 

 the juice was of a bright purple ; but by the time it had reach- 

 ed through the spout to the clarifier (a very short distance) it 

 became of a dingy iron colour. I am told the Batavia sugar 

 imported into Amsterdam is very fair; so that if those canes 

 should otherwise answer well, means may doubtless be obtain- 

 ed to discharge the purple tinge from their juice."
