A large amount of information, mainly of a practical character, has been gathered by Mr. _William J. Clark_ in his book on _Commercial Cuba_[39]--information, as Mr. Gould well says in the introduction he has contributed to the work, covering almost the entire field of inquiry regarding Cuba and its resources. The data have been partly gained from the author's personal observation and during his travels on the island, and partly through laborious and painstaking classification of existing material, collected from many and diverse sources. The subject is systematically treated. The first chapter--How to Meet the Resident of Cuba--relates to the behavior of visitors to the island, really a considerably more important matter than it would be in this country, for the Spaniards are strict in their regard for correct etiquette. It is natural that a chapter on the population and its characteristics and occupations should follow this. Even more important than correct behavior--to any one at least but a Spaniard--is the subject of climate and the preservation of health; and whatever is of moment in relation to these subjects is given in the chapter devoted to them. Next the geographical characteristics of Cuba are described, and the facilities and methods of transportation and communication; also social and political matters, including government, banking, and commercial finance, and legal and administrative systems of the past and future. A chapter is given to Animal and Vegetable Life, another to Sugar and Tobacco, and a third to Some General Statistics, after which the several provinces--Pinar del Rio, the city and province of Havana (including the Isle of Pines), and the provinces of Matanzas, Santa Clara, Puerto Principe, and Santiago--are described in detail, with their physical characteristics, their agricultural or mining resources, their various towns, and whatever else in them is of interest to the student of economics. A Cuban Business Directory is given in the appendix.
