Gharial is the name of a boat. The boat is pictured on side B of Indus tablet M-1429. The inscription begins on side C of M-1429 with this pictograph. The image can be read literally as an engraving of a gharial catching a fish. However, the 'fish' shape also resembles the Indus symbol for the verb to deliver (Mahadevan's sign number 59). Hence, side C can be read as 'Gharial delivery'.

On side B, we learn, through a picture, that the Gharial is a cormorant fishing boat with three cormorants. Then in the inscription on side A, we are invited to take a look at the catch. Side A might be read as 'Three divers deliver their catch. Take a look at the large consignment'.
