Leaf tobacco, fumigated at the rate of 32 grams per cubic 

 meter, was made into cigars on different dates, care was taken 

 to prevent reinfestation, and cigars were examined at intervals. 

 The following table gives results of these experiments:

A check, in which samples taken from different lots of treated 

 tobacco were made into cigars and subjected to factory condi- 

 tions, was carried on simultaneously with these experiments, and 

 in all cases, as shown in Table XVII, the cigars became rein- 

 fested. 



The cost of fumigating 1,400 kilograms of leaf tobacco la 

 about 15 centavos per 1,000 cigars, when the carbon bisulphide 

 is purchased at the local price and is used at the rate of 1.25 

 kilograms to 32 cubic meters or 39 grams per cubic meter.
