Arthashastra
अन्त पालः पण्य सम्पात अनुग्रहेण वर्तयति, वैदेहकास् तु सम्भूय पण्यानाम् उत्कर्ष अपकर्षं कुर्वाणाः पणे पण शतं कुम्भे कुम्भ शतम् इत्य् आजीवन्ति ॥
the superintendent of the boundary increases commercial traffic by welcoming the arrival of merchandise, whereas traders unite in causing rise and fall in the value of articles, and live by making profits cent per cent in panas or kumbhas (measures of grain).
