The Ortega family at Rancho Refugio did a brisk business in clandestine trade with visiting ships.
According to Katherine Plummer, in March of 1815, the Forester stopped there and loaded firewood, salted beef, and 11 hogs. That's too much pork to serve at once so perhaps the pigs were salted or caged.
According to Antipatr Baranov's journal, in September (O.S.) of the same year the Russian-American Company's Ilmena came by and "bought one cow for ship's provisions". I presume it was slaughtered immediately. At another rendezvous six days later, Mr. Ortega "brought some cattle for provisions"; the ship needed "no more than six bulls". The transaction never happened because the landing party was arrested.
The Ilmena was a 200-ton brig with a crew of 25. One cow a week for provisions seems reasonable. I wondered if the translation was accurate and checked the original; indeed the word was Быков, bulls. I'm not sure if that word can describe breeding pairs. What was the crew going to do with six bulls?
