This ideograph combines the pictograph of a jar with the verb to rise. The verb to rise in Indus script is equivalent to the Chinese character shān 彡. The level of the contents in a jar rises up as the jar is filled. Hence, this is the Indus noun contents.

Indus inscription H-1727 is found on a damaged pot. Therefore, part of this character is missing. Nonetheless, we can be fairly certain that the character was Mahadevan's sign number 1434. It is especially interesting that the two character inscription reads: 'guard contents.'
