Read the following excerpt from Margaret Frink's J​ ournal of the Adventures of a Party of California Gold-seekers.​ Mr. Wand and his company have left their wagons here and made pack-saddles, intending to pack their clothing, blankets, provisions, and cooking utensils on their animals, in order to travel faster. They stopped here two days for that purpose, and are now ready to start. Mr. Johnson, of Morgan County, Indiana, had been with Mr. Wand's party up to this time, but preferring not to pack through, made arrangements with Mr. Frink to travel with us. His horse, a good animal, was harnessed to our wagon and proved quite useful.
