Arion was again appointed Public Instruction Minister in 1910, when Carp was named Premier of a Conservative cabinet. He preserved this position after Carp was replaced with Maiorescu, while also serving as head of Internal Affairs and Agriculture and Royal Domains. It fell on Arion to adopt the set of agricultural reforms that National Liberal politicians had been postponing ever since the Peasants' Revolt of 1907. At Public Instruction, he also granted religious and educational privileges to the Albanian-Romanian community. During the interval, he was elected honorary member of the Romanian Academy.
