According to the Casati Law, that between 1859, when it was issued within the Kingdom of Sardinia, and 1923 regulated the education system in the whole Kingdom of Italy, the first two classes of the elementary school, especially due to another decree, the Coppino Law of 1877, were to be compulsory and free for every Italian citizen, but who had to fund schools and education were the various Italian municipalities. Nonetheless, albeit elementary schools and education were supposed to be entirely provided by Arbus municipality, the commune could economically contribute very little to citizens' education, so much so that, according to Lord Brassey, while he used to pay about 15,000 lire to the commune for the purpose of offering education options to citizens, the commune contributed only with the unarguably low sum of 600 lire. Nevertheless, Lord Brassey also agreed that, when education was provided to adult or young workmen, it was fair that it was solely at the expense of the company. For the purpose of partly overcoming this issue, the mining company also tried to offer evening classes for workmen.
