The specially or incompletely de-natured alcohol can only be used by special permission, for which the manufacturer must apply, at the same time giving full details as to business, plant, premises, the special de-naturants desired to be used, and the reason therefor, etc. (Section 81). Section 82 recites the necessary requirements as to storerooms, etc., and Sections 83 to 87 relate to the form of application and the inspection of the plant. Section 88 recites the form of bond necessary to be given by the manufacturer, and Sections 89 to 104 relate to the general requirements as to records, books, affidavits, etc. Sections 105 and 106 rule that the alcohol must be used just as received, and as called for in the permit, and that a manufacturer quitting business may dispose of his specially de-natured alcohol to other manufacturers. PROVISIONS APPLICABLE TO MANUFACTURERS USING EITHER SPECIALLY OR GENERALLY DE-NATURED ALCOHOL. "SEC. 107. Under no circumstances will de-naturers, manufacturers, or dealers, or any other persons, in any manner treat either specially or completely de-natured alcohol by adding anything to it or taking anything from it until it is ready for the use for which it is to be employed. It must go into manufacture or consumption in exactly the same condition that it was when it left the de-naturer. Diluting completely de-natured alcohol will be held to be such manipulation as is forbidden by law. "SEC. 108. Manufacturers using either specially or completely de-natured alcohol must store it in the storeroom set apart for that purpose, the place for deposit named in the bond and application, and nowhere else. Likewise they must deposit recovered alcohol in said storeroom as fast as it is recovered. It will be held to be a breach of the bond and a violation of the law if any alcohol of any kind, character, or description should be found stored at any other place on the premises." The question of special de-naturants is one of great importance to the manufacturer, and should be carefully studied. The distiller who succeeds on a large scale will be he who is most expert in preparing alcohol specially de-natured to suit the requirements of the various arts. Germany has done most in this line, and the German practice should be carefully studied. Parts IV and V of the Rules relate to that portion of the De-Naturing Act, referred to in Section 2 thereof--the recovering, restoring and re-de-naturing of alcohol used by manufacturers employing processes in which the formerly de-natured spirits are? expressed, or evaporated. This not being within the plan of this book, the rules relating thereto are not quoted.
