This series is divided into two subseries. Subseries 1: Student drawings consist of 196 drawings made by Alexander M. Welch roughly between 1886 and 1903. Some drawings were made for class assignments when Welch was a student at Columbia. They include drawing exercises, engineering exercises, plans, elevations, renderings and the like. The collection also includes sketches from Welch's travels in Europe and his drawings from when he studied at L'École des Beaux-Arts in Paris. Subseries 2: Student Notebooks includes 14 course notebooks, 1 sketchbook, and 1 journal. The course notebooks include some drawings but are mostly detail notes from lectures given by Columbia School of Mines professors including figures such as William R. Ware, Russell Sturgis, James Greenleaf, John Newberry, and David W. King.
