Van Gaasbeek Richard. A practical course in wooden boat and ship building

Chicago, Frederick J. Drake & Company publishers, 1919, 250 p.The text is the outgrowth and development of a pioneer course organized early in the war by Pratt Institute, Brooklyn, N.Y., in response to the demand caused by shortage of skilled labor in these industries.
It was a study to know how to organize the work effectively, to select only those problems that otherwise might take years of labor in the industry for these men to solve, and to present the problems progressively and in such a way that the men would grasp the basic principles in the shortest possible time.
