Before you start learning about buying and selling metal you decide to thank Iddin-Sin for helping you on the journey from Sippar. In one of the main squares, you see a scribe sitting cross-legged on a bench. For a small amount of silver he will write a letter for you and have it sent by messenger. He is busy writing something for a tall man and you watch as the scribe quickly uses a sharpened reed to make little wedge-shaped signs in a small cushion of clay he holds in his hand. Soon it is your turn. Iddin-Sin will have the letter read to him by his own scribe. Your letter reads:

'To Iddin-Sin say the following: I have travelled to Uruk and met my cousin. I shall stay here for two months to learn about metal. You should be pleased. May all be well with you, your wife and your child'.
