On the first line, the date of the crop is filled in ; on 

 the second, the number of the field showing- at the same 

 time, the gang responsible for the rubber. The third line 

 specifies the quality of the rubber. "No. i". means first- 

 class rubber prepared from latex. "Lump" is the rubber, 

 which coagulated in the cups, strained out before the 

 fluid latex is dealt with. "Skimmings" means the rubber 

 obtained from the scum taken off the pails, strainers etc. 

 These three qualities produce a rubber of about the 

 same market value. "Scrap" was gathered by the tappers 

 daily ; separate gangs of women and children being 

 employed on the alternate day system. The shavings 

 are always gathered by women ; the earth rubber by a 

 separate gang going through the whole estate, and 

 therefore not allocated to specified fields. "Number of 

 lengths" means the number of the strips of crepe 

 obtained from the different qualities, and, on the last 

 line, the weight is filled in. All these figures are

again entered in the Ledger, and on each parcel, the 

 percentage which the different qualities bear to the bulk 

 is calculated. 



With such a complex system, it is often possible to 

 discover mistakes which otherwise would not be observed. 

 An example of this is the following; It was remarked 

 that with gangs which worked every day and collected 

 their own scrap, the percentage of this was lower and 

 that of the bark rubber was higher than with gangs where 

 the collection of scrap and latex was made by different 

 labourers. On close investigation, it appeared that the 

 former gathered their scrap with less care and left a 

 great part on the trees, which was therefore brought in 

 with the shavings.
