Scrapbook of newspaper clippings on mechanical engineering topics. Many of the articles focus on the investigation following the explosion of the Westfield, including testimony and reports of various engineers, including a report by Thurston himself. Several other articles describe the exhibits at the Vienna International Exhibition of 1873. In creating the scrapbook, Thurston reused a ledger from the firm R.L. Thurston & Co. (1842-1844), which did engine repairs and related work for its customers. About half of the original ledger remains visible; the rest is hidden beneath the glued-in newspaper articles of the later scrapbook.
