          The year 1850 may be considered the beginning of a new epoch in America art, with respect to the development of watercolor painting.

In addition to securing an exhibition space in the Library Society building in lower Manhattan, the society founded a small school for the instruction of watercolor painting Periodic exhibitions of the members' paintings also included works by noted English artists of the day, borrowed from embryonic private collections in the city.

No further attempt to formally organize the growing numbers of watercolor painters in New York City was made for more than a decade. During that decade, though, Henry Warren's Painting in Water Color was published in New York City in 1856-the book was a considerable improvement over the only other manual of instruction existing at the time, Elements of Graphic Art, by Archibald Roberson, published in 1802 and by the 1850's long out of print.
