After this he published new works regularly. In 1877, he created La Pomme, an association of Bretons and Normans, of which he became president the following year. In 1889, a monthly journal of the same name was created. In 1881 he initiated with Charles Leclerc the publication Collection des Littératures populaires de toutes les nations (Collection of the Popular Literatures of all Nations), to which he contributed La littérature orale de la Haute-Bretagne (Oral Literature of Upper Brittany). In 1882, came the creation of the Société des Traditions populaires, which organized the Dîners de ma Mère l'Oye, meetings of folklorists which gave rise to the journal of the same name. From 1886 he became the general secretary of the association and assumed the direction of the journal.
