What was advertised in a colonial American newspaper 250 years ago today?

“Some evil minded Person or Persons have wickedly and falsely spread a Report, that I put Soap Suds and Pot-Ash in my Bread.”
As summer turned to fall in 1769, Christopher Smieller took to the pages of New-London Gazette to defend his reputation and mitigate damage already done to his business. The baker had become aware of a vicious rumor about his bread. In a lengthy nota bene at the conclusion of even lengthier advertisement, he expressed his outrage that “some evil minded Person or Persons have wickedly and falsely spread a Report, that I put Soap Suds and Pot-Ash in my Bread.” Smellier could not let this slander pass unremarked. Instead, he offered “a Reward of Two Dollars to any Person who will inform me of such Defamers that they may be prosecuted according to law.” In order to rehabilitate his standing in the community, he also made provision for witnesses to observe him as he went about his business: “I will permit any two or three honest Men to stay with me 24 Hours, who may inspect every Article put into my Bread.”
Combatting gossip circulating about unsavory additions to his bread may have prompted Smieller to insert other aspects of his lengthy advertisement. It opened like many other advertisements for consumer goods, listing his wares. Smieller also advanced an appeal to price, stating that he sold loaf and ship bread, gingerbread, cakes, and pies “as cheap as in any of the neighbouring Governments.” In other words, his prices in New London were as good as prospective customers could find in Massachusetts, New York, or Rhode Island. He doubled down on this assertion later in the advertisement, proclaiming the he baked ship bread “as good and as cheap as in any Part of America.”
Smieller tied the prices he charged for bread to the prevailing prices for flour. He made allusion to “sundry Persons who call themselves Bakers” who had been overcharging the residents of New London and making it unaffordable for them to buy bread. To demonstrate that he charged fair prices, Smieller specified how much a loaf of bread weighed and the corresponding price at the current price for flour. He explained that he would adjust the price per loaf as his own costs for flour fluctuated, but that he would hold his profit consistent. He hoped current and prospective customers would patronize his business out of appreciation for his commitment to keeping prices low by earning “so very small” profits on his bread. Smieller might not otherwise have outlined the expenditures and profits for his business, but defending himself against the rumor that he put soap and potash in his bread may have motivated him to devise other methods of convincing the people of New London to purchase from him.
