The other, polished rices on the contrary, were found to 

 be little if anything affected in these 5 months. Most of 

 the weevils appeared in the rice intended for the army; 

 then followed the white rice (sosok); while in the highly 

 polished rice (sikat) scarcely a single insect was to be found. 



This connection between the amount of silver-skin and 

 the damage done, is the more remarkable because the 

 various kinds of rice were stored in each others' immediate 

 vicinity. The amount of powderformation kept pace with 

 the number of insects. 



Although the results of these observations pretty well 

 practically answered the questions as to how long unpolished 

 rice could be stored without special precautions, — for the 

 measures then taken might be considered as the most normal, 

 or at least the most generally used, — it was still desirable 

 to specially examine the influence of storage under somewhat 

 different conditions, and thus to gain an impression as to 

 the influence of such factors as light, rest and ventilation. 



For this purpose proofs were taken with storing in glass 

 stoppered-bottles of different colours and parcels of variously 

 coloured paper. Some of these paper parcels, which were 

 suspended quite free in the air, were inspected at least 

 once a week, and the others only once a month. 



The standard for judging the deterioration could scarcely 

 be any other than the time when insects appeared and 

 especially their relative number. It was practically not 

 possible to take into account the grade of infection through 

 insect-germs during the treatment which it had undergone, 

 and this is an other reason for not going into less speaking 

 details in the following description. 



The experience with the polished kinds of rice can be 

 very briefly described : the least milled kinds began to show 

 a few insects at the and of about 4 months: even in the 

 samples packed in paper the number of these insects was 

 very small and their increase was very limited. Finished 

 white rice showed no weevils in 4 months so that the fact
