How to Install Electric Bells, Annunciators, and Alarms

A New American Book on Industrial Alcohol

A Practical Handbook on the Distillation of Alcohol — From Farm Products and De-Naturing Alcohol

By F. B. WRIGHT.

Including the Free Alcohol Law and its Amendment, the Government regulations therefore and a number of U. S. government authorized de-naturing formulas.

In the preparation of this, the second edition, the author has followed his original plan of writing a plain practical handbook on the manufacture of alcohol and de-naturing for industrial purposes. This industry is bound to grow to enormous proportions as it has in Germany where over 100,000,000 gallons were manufactured last year principally in small farm distilleries. This work is not intended as a scientific treatise but as a help to farmers and others wishing to go into this industry on a moderate scale.

The original matter has been carefully revised. Some of the chapters rewritten and a very considerable amount of new information added. The total number of illustrations brought up to 60 including a number of plates giving the layout of distilleries.
