Diffusion versus Double Crushing. 231 



sufficient for measuring any improvement in the recovery 

 of juice from cane, and therefore becomes fatal if it is 

 applied for such a purpose. 



I have twice in my life experienced a change of stan- 

 dard measures in public life, and therefore know the 

 difficulty which almost everybody has to encounter in 

 getting accustomed to a new standard. Indeed there 

 were people who would stick 1;o their old modes of 

 measuring until the end of their lives in spite of the 

 laws and Police Ordinances which do not allow of being 

 joked at within the fatherland, This was on the occasion 

 of the introdu6lion of the metric system and the new 

 coinage in 1873. 



Nor need this surprise us. We all very likely have a 

 precise idea in our minds about, say, the area of 100 

 acres, or about the size of a building, the length or width 

 of which are expressed to us in feet, but I doubt whether 

 there are not a few among us who would be puzzled if the 

 same dimensions were given them in square metres and 

 millimetres. Still it would be easy enough for them 

 to transfer the given measure into their own mode of 

 reckoning. 



This is not the same with the appreciation of diffusion, 

 It is not merely a matter of turning one standard into 

 the other, but the old standard has to be abandoned 

 completely, and an entirely new one has to be adopted. 



According to the usual manner of reckoning in this 

 colony the differences of crushing would be 



with single crushing, 62 tons juice, losing 26 tons juice by megasse: 

 with double crushing, 72 tons juice, losing 16 tons juice by megasse : 

 with diffusion, 85 tons juice, losing 3 tons juice by megasse. 



You can therefore see that by diffusion you gain 13 tons 

 original juice on every 100 tons of cane worked up.
