The Esparvienne library occupied the whole of the second floor of the old house. The works thought to be of but mediocre interest, such as books of Protestant exegesis of the nineteenth and twentieth centuries, the gift of Monsieur Gaétan, were relegated unbound to the limbo of the upper regions. The catalogue, with its various supplements, ran into no less than eighteen folio volumes. It was quite up to date, and the library was in perfect order. Monsieur Julien Sariette, archivist and palæographer, who, being poor and retiring, used to make his living by teaching, became, in 1895, tutor to young Maurice on the recommendation of the Bishop of Agra, and with scarcely an interval found himself curator of the Bibliothèque Esparvienne. Endowed with business-like energy and dogged patience, Monsieur Sariette himself classified all the members of this vast body. The system he invented and put into practice was so complicated, the labels he put on the books were made up of so many capital letters and small letters, both Latin and Greek, so many Arabic and Roman numerals, asterisks, double asterisks, triple asterisks, and those signs which in arithmetic express powers and roots, that the mere study of it would have involved more time and labour than would have been required for the complete mastery of algebra, and as no one could be found who would give the hours, that might be more profitably employed in discovering the law of numbers, to the solving of these cryptic symbols, Monsieur Sariette remained the only one capable of finding his way among the intricacies of his system, and without his help it had become an utter impossibility to discover, among the three hundred and sixty thousand volumes confided to his care, the particular volume one happened to require. Such was the result of his labours. Far from complaining about it, he experienced on the contrary a lively satisfaction.
