THIS book is one of the most usable of the recently published collections of drinker's recipes: in the first place, the pages and cover are waterproofed; then there is a more than adequate system of indices, including both the ordinary type of index and a cut-back page effect; the result is that anyone can locate the best drink of a given base in a minimum of time, and with a minimum of thought. One can, by employing the manual, adjust the drinks to what there is on hand in the way of liquors and mixers with uncanny accuracy; the forthcoming drinks, experiment shows, are more potable than the average shot-in-the-dark concoction.
