An accomplished carpenter and boat builder, Patrick Gass proved to be an invaluable and well-liked member of the Lewis and Clark expedition. Promoted to sergeant after the death of Charles Floyd, Gass was almost certainly responsible for supervising the building of Forts Mandan and Clatsop. His records of those forts and of the earth lodges of the Mandans and Hidatsas are particularly detailed and useful. Gass was the last survivor of the Corps of Discovery, living until 1870 - long enough to see trains cross a continent that he had helped open. His engaging and detailed journal became the first published account of the Lewis and Clark expedition.
This is more of an overview of the entire cartooning profession rather than a how-to-draw book, and as such, is very useful. I especially appreciated the parts that teach how to look at everything in the world, from clothing folds to how people and animals move to vanishing points, with new eyes - it's parallel to what I teach my students about listening. Allowances need to be made for how much technology has changed since the book was published in 2001, but beyond that, most of what the book has to offer still applies today. Potentially useful both to aspiring cartoonists and to those wanting to incorporate cartoons into website or publishing projects.
