From the same cause arose at this time an important development of the political organization of the island. Nominally, all the provincial capitals were of equal dignity. But the smelting works and assay office were at Santiago, and thither, therefore, all gold miners had to repair at intervals, to have their nuggets, dust and ore refined and its value determined. They came in the spring, just before the beginning of the rainy season. Naturally their coming thither attracted at the same time tradesmen from all parts of the island, and Santiago thus became the business and social metropolis. Moreover, each of the other provincial capitals deemed it profitable to send to Santiago at that time an official representative of its local government. These procuradors, as they were called, came together at Santiago to exchange experiences and advice and to confer for the general welfare of their respective communities. Thus early in Cuban history were the rudiments of a representative insular legislature established; through the influence of which the various provinces were drawn together in sympathy and made uniform in administration, and the foundations of Cuban nationality were laid. Soon, indeed, a regular organization was voluntarily formed, with the Alcalde of Santiago as presiding officer and with rules of order and a programme of procedure. As a result of each annual session of this primitive insular council an address was prepared for transmission to the King of Spain. This consisted of a report upon the condition, progress and prospects of the island, and a request for the supplying of its legislative, administrative or other needs. In the presentation of this address the insular council performed a function practically identical with that of the Spanish Cortes of that time; a body which had no legislative or other authority, but merely the privilege of protest and petition to the King. Usually a procurador representing the council was despatched to Spain, to present the address in person to the King; who was received with something of the attention and honor which were paid to important foreign ambassadors.
