Note
1. In 1826 was the standard to calculate the cargo capacity of a ship the so-called roggelast (rogge=rye) of 2.075 kilo’s. In 1827 made the Nederlandsche Handels Maatschappij a list of all colonial products with their weights corresponding with the space needed for one roggelast. This became known as the Java last. For instance the weight of a Java last tea was 1.000 kilo, of pepper 1.600, of rice 2.000 and of coffee 1.500 kilo (in the practice in fact 1.800).
