Propaganda was organized by the Sicilian La Farina by means of the Societd Nazionale.
There he became a convert from republicanism to monarchism, being convinced that only under the auspices of King Victor Emmanuel could Italy be freed, and together with Giorgio Pallavicini and Giuseppe La Farina he founded the Societd Nazionale Italiana with the object of propagating the idea of unity under the Piedmontese monarchy.
Occasionally acts of chastisement, of which the bombardment of Porto Farina by Blake in 1655 was the most notable, and repeated treaties, extorted by European powers, checked from time to time, but did not put an end to, the habitual piracies, on which indeed the public revenue of Tunis was mainly dependent.
In December 1654 Penn and Venables sailed for the West Indies with orders to attack the Spanish colonies and the French shipping; and for the first time since the Plantagenets an English fleet appeared in the Mediterranean, where Blake upheld the supremacy of the English flag, made a treaty with the dey of Algiers, destroyed the castles and ships of the dey of Tunis at Porto Farina on the 4th of April 1655, and liberated the English prisoners captured by the pirates.
Porto Farina was the naval arsenal of the piratical beys of Tunis and was bombarded by the English under Admiral Blake in 16J5.
In 1703 Samuel Morland, in a paper read before the Royal Society, stated that the farina (pollen) is a congeries of seminal plants, one of which must be conveyed into every ovum or seed before it can become prolific. In this remarkable statement he seems to anticipate in part the discoveries afterwards made as to pollen tubes, and more particularly the peculiar views promulgated by Schleiden.
La Farina was accordingly sent to Palermo to urge the immediate annexation of Sicily to Piedmont.
