The book presents data and a number of unique photographs in a near-pamphlet published in 1930 to attract investors and tourists to the fledgling French colony of Laos. The book also includes an assessment of development work done there and challenges for the future by staunch colonialist Pierre Deloncle. Especially early mining successes are discussed as an example of successful private initiative. The book is based on the travels of novelist Jean Renaud, in the company of Albert Sarraut, another scholar of Laos and Indochina and on published sources. Special attention is given to various proposed access roads to link Laos with the rest of Indochina and to access the wealth of the Plain of Jars. Besides a number of polemic arguments in favor of the colony, there are some salient facts of its natural setting, history, geography and various highland tribes. The great importance and significance of religious superstitions and customary ceremonies are also discussed.
