The first work of the new administration was a general forest survey to ascertain conditions, and especially to determine which of the public forests, under the laws of 1855 and 1859, it was desirable to retain. The investigation showed that there was more forest (defined as in the above classification) than had been supposed, but that it was in even worse condition than had been known. The public forests, i.e., those owned by the State, the communities and public institutions, were divided into three classes according to the species by which formed, which was the easiest way of determining their location as regards altitude, and their public value; namely, the coniferous forest and deciduous oak and chestnut forests, which were declared inalienable; the forests of ash, alder, willow, etc., naturally located in the lower levels, therefore without interest to the state, which were declared salable; and an intermediate third class composed of cork oak and evergreen oak, whose status as to propriety of sale was left in doubt. In 1862, a revision of this classification left out this doubtful class, adding it and the forest areas of the first class which were not at least 250 acres in extent to the salable property. The first class, which was to be reserved, was found to comprise nearly 17 million acres (of which 1.2 million was owned by the State), while the salable property was found to be about half that area. Ever since, a constant wrangle and commotion has been kept up regarding the classification, and repeated attempts, sometimes successful, have been made by one faction, usually led by the Minister of Finance, to reduce the public forest area (_desamortizadoro_), opposed by another faction under the lead of the forest administration, which was forced again and again to re-classify. In 1883, the alienable public forest area was by decree placed under the Minister of Finance, the inalienable part remaining under the Minister of Public Works (_Fomento_); very much the same as it was in the United States until recently. The public debt and immediate financial needs of the corporations gave the incentive for desiring the disposal of forest property, and, to satisfy this demand, it was ordered, in 1878, that all receipts from the State property and 20 per cent. of the receipts from communal forests were to be applied towards the extinguishment of the debt.
