the long version

"This bulletin has been prepared with two purposes in view : First, to outline the conditions which must be considered before attempting to make denatured alcohol, and second, to give in detail the practical methods for the manufacture of alcohol from potatoes. A discussion of general conditions is given in order to answer the many inquiries received at the Department as to the availability of various materials and it is hoped that persons interested, by a careful reading of this section, will be able to decide for themselves as to the value of any proposed material and the possibility of successfully making alcohol from it under their respective local conditions"--Purpose of the bulletin (p.5).
