Albert L. Hurtado said this quote

“ Before Sutter, native people had heeded the cycle of the seasons, time was infinite, and life's rhythms were unchanging. Now, for at least part of their lives, some Indians were wedded to a concept that proclaimed that time was limited and that it had economic value. The clang of Sutter's bell announced that time was money, that it marched onward, and that it waited for no man, including Indians in the 1840s. ”
