The blocking up the harbor at this time appears to have been more effective than convenient. Twenty boats or rafts filled with earth and stone were sunk with a purpose of destroying the harbor. De Saint Luc, the governor, succeeded in removing only four or five. The entrance for vessels afterward remained difficult except at high tide. Subsequently Cardinal de Richelieu expended a hundred thousand francs to remove the rest, but did not succeed in removing one of them.--_Vide Histoire de La Rochelle_, par Arcere, Tom I. p. 121. 7. The Prince of Condé. "Leaving Monsieur de St. Mesmes with the Infantry and Artillery at the Siege of Brouage, and giving order that the Fleet should continue to block it up by sea, he departed upon the eight of October to relieve the Castle of Angiers with 800 Gentlemen and 1400 Harquebuziers on horseback."--_Davila_, p. 583.

"_St. Luc_ sallying out of Brouage, and following those that were scattered severall wayes, made a great slaughter of them in many places; whereupon the Commander, despairing to rally the Army any more, got away as well as they could possibly, to secure their own strong holds."-- _His. Civ. Warres of France_, by Henrico Caterino Davila, London, 1647, p 588. 9. An old writer gives us some idea of the vast quantities of salt exported from France by the amount sent to a single country. "Important denique sexies mille vel circiter centenarios salis, quorum singuli constant centenis modiis, ducentenas ut minimum & vicenas quinas, vel & tricenas, pro salis ipsius candore puritateque, libras pondo pendentibus, sena igitur libras centenariorum millia, computatis in singulos aureis nummis tricenis, centum & octoginta reserunt aureorum millia."--_Belguae Descrtptio_, a Lud. Gvicciardino, Amstelodami, 1652, p. 244. TRANSLATION.--They import in fine 6000 centenarii of salt, each one of which contains 100 bushels, weighing at least 225 or 230 pounds, according to the purity and whiteness of the salt; therefore six thousand centenarii, computing each at thirty golden nummi, amount to 180,000 aurei. It may not be easy to determine the value of this importation in money, since the value of gold is constantly changing, but the quantity imported may be readily determined, which was according to the above statement, 67,500 tons. A treaty of April 30, 1527, between Francis I. of France and Henry VIII. of England, provided as follows:--"And, besides, should furnish unto the said _Henry_, as long as hee lived, yearly, of the Salt of _Brouage_, the value of fifteene thousand Crownes."--_Life and Raigne of Henry VIII._, by Lord Herbert of Cherbury, London, 1649, p. 206.
