Eventually Mr. Haddock appeared at the offices of the Collector of Taxes, and delivered to him a large white cow "of malevolent aspect". On the cow was stencilled in red ink:
- To the
Londonand Literary Bank, Limited
- Pay the Collector of Taxes, who is no gentleman, or Order, the sum of fifty seven pounds £57/0/0 (and may he rot!)
- ALBERT HADDOCK
Mr. Haddock tendered the cow to the Collector in payment of his tax bill and promptly demanded a receipt.
During the "hearing", the fictitious judge, Sir Basil String, enquired whether stamp duty had been paid on the negotiable instrument. The fictitious prosecutor, Sir Joshua Hoot KC confirmed that a two-penny stamp was affixed to the dexter horn of the cow.
The Collector declined the cow, and had objected that it would be impossible to pay the cow into a bank account. Perhaps unhelpfully, Mr Haddock suggested that the Collector could endorse the cow to any third party to whom the Collector might owe money, adding that "there must be many persons in that position".
