Carpentry and Joinery by Gilbert Townsend

"With all the strides which have been made in steel and concrete construction, and in the face of the developments in mill work and in the manufacture of special building material, no method has ever been devised for dispensing with the services of the skilled worker in wood. His knowledge of lumber and of its behavior under varying conditions; his ability to perform rapidly and in workmanlike manner the many details connected with the frame, the roof, the walls, and the exterior and interior finish ; and his technical knowledge of the simpler elements of construction make him an efficient workman, and give him the ability to rise to higher things". --Introduction.
