For all his life, Provancher would remain the owner and editor of the journal, as well as its main contributor, although a number of other prominent naturalists of the time also published in it: Dominique-Napoléon Saint-Cyr, Charles-Eusèbe Dionne (who also for a time edited a concurrent journal), François-Xavier Bélanger, Joseph-Alexandre Crevier, James MacPherson Le Moine and Jean-Baptiste Meilleur amongst others. Their combined contribution amount to less than a hundred pages; Provancher providing the vast majority of the journal's content, over 6,000 pages' worth. While many articles treated scientific topics, Provancher also wrote essays on related topics such as public education, the establishment of museums, and a botanical garden project in Quebec City. Soon after it was launched, having reached 500 subscription (a rather high rate when 50% of the population couldn't sign their name), it received a government grant to help with publication.
