A similar experiment was carried out in February 1912. Four 

 new pots were used for collecting juice without previous smoking. 

 The following morning two of these were smoked by the native 

 process. That evening a quantity (900 c.c.) of juice was collected 

 and analysed. 225 c.c. was then put into each of the four pots, 

 and these were hung on trees overnight. 



The table shows the result : 



All the juices used in February 1911 for this experiment were 

 faintly acid. The juice used in 1912 was distinctly alkaline. 



In every case we see that the juice kept in the smoked pots 

 has not deteriorated so much as that in the unsmoked ones. We 

 must conclude that smoking has a beneficial effect.
