A group of travelers and their horses at rest on the Sacramento River in this undated drawing by A.T. Agate, engraved by J. W. Steel. Plants and flowers indicate a spring-time outing with perhaps the Sutter Buttes in the background? Alfred Agate was one of the first American artists to visit California. He came as part of the United States Exploring Expedition of 1838-1842, generally called the Wilkes' Expedition. This expedition was comprised of not only explorers, but botanists, zoologists, geologists and artists. Title from caption on piece. Engraving done by J.W. Steel, a Philadelphia engraver.
