A two-page installment (No. X) of a series on the textile industry at the 1873 Vienna Exhibition, by Dr. H. Grothe. It explains what silk waste is (waste from winding and throwing, defective cocoons, strazza, stami) and its preparatory fermentation, then describes the machines shown by Theodor and Frederic Bell of Kriens, near Lucerne. These are a stamping machine, an opening machine, a comber or drawing frame, and a carding machine. The text covers how each works and gives output and power figures, with an illustrated plate of six machinery figures.
