You are now in possession of about all the latest and most useful receipts that are in the country; many of which are now being sold, frequently, for from $5 to $10 and $20 each; and if you will now be wise, do that which will be to your own interest, allow no man to see this work, but keep the receipts profoundly secret, except as you sell them. You may dispose of enough of them, written off, every year you have the book, to amount to twenty times the price of it.
