The whole list of substitutes used for juniper is a rather long one: coriander, almond, powdered angelica and cayenne pepper are mentioned by Emerson as among the hosts of substances that are found to be cheaper and easier to use than the juniper berry. The kind of gin which is made in England is commonly called "Old Tom." The story which explains the origin of this term also discloses the first account of the "Blind Tiger" which I have been able to find in literature. It is quoted by Emerson from "The Life and Uncommon Adventures of Captain Dudley Bradstreet." When the Captain decided to start the "Blind Tiger" he laid in a stock of 13 pounds worth ($65) of good gin. He had the cargo sent to his house, at the back of which there was a way to go in or out. He had a person to inform a few of the mob that gin would be sold by the old cat at the window next day provided they put the money in his mouth, from which there was a hole which conveyed it to the proper authority. It was over three hours before anybody called, which made the Captain almost despair of his project. At last, however, he heard the clink of money and a voice say, "Puss! give me two pennyworth of gin!" The Captain instantly put his mouth to the tube and bid the buyer receive it from the pipe under her paw, and then measured and poured it out. The first day he took in 6 shillings, the next day 30 shillings, and afterward three or four pounds a day. From all parts of London people came in such numbers that his neighbors could scarcely get in and out of their houses. The Old Tom Cat became an institution and since that time gin has been known as Old Tom.
