The materiel of the Italian navy has been completely transformed, especially in Virtue of the bill of the 31st of March 1875.
Not having sufficient materiel for two sieges, he laid siege to San Sebastian only, and blockaded Pampeluna.
On the other hand, the deep sandy soil near its banks made the transport of bridging materiel by land laborious, and almost certain of discovery.
A first-class arsenal, which can renew the materiel and equipment of a large army, embraces a gun factory, carriage factory, laboratory and small-arms ammunition factory, small-arms factory, harness, saddlery and tent factories, and a powder factory; in addition it must possess great store-houses.
When the Committee of Public Safety made an appeal to the savants to assist in producing the materiel required for the defence of the republic, he applied himself wholly to these operations, and, distinguished himself by his indefatigable activity therein; he wrote at this time his Description de fart de fabriquer les canons, and his Avis aux ouvriers fer sur la fabrication de l'acier.
