[Footnote 6: 96-423/1000 Austrian feet = 100 English.] The superficial area of the ship, or the load-water line, amounted to 5685.35 square feet; quantity of water displaced 2107 Austrian, or 2630 English tons. The superficial area of the principal sails amounted to 18,291 square feet. The frigate proved herself to be an excellent sailer, as, of the various vessels which, throughout the voyage, sailed in company with us, only three clippers outstripped her. The question may here be asked, why, in the present state of navigation, a sailing-vessel was preferred to a steamer for this voyage? The principal consideration which decided this selection was the greater disposable area which a sailing-vessel offers in comparison with a steamer of the same dimensions, in which coal and machinery occupy so large a space. On the present occasion, it will be perceived that what was specially wanted was room for as great a number of officers, cadets, and men as possible, who were, as has been stated, to make this voyage for improvement in nautical affairs. Plenty of space was also required for the numerous instruments and bulky collections of objects of natural history; while in most parts of the ocean which we were to traverse, the winds blow so regularly, that, with very rare exceptions, sails form the best motive power. The expense of fuel requisite for a steamer, and the trouble of replacing it during the voyage, are thus saved; whilst, finally, the space occupied by the men employed in the management of the machinery, and that required for the stowage of special stores, would be withdrawn from more important objects. After the frigate had been properly fitted up in the arsenal of Pola, she sailed on the 15th March, 1857, for Trieste, where she cast anchor on the 17th in the Bay of Muggia. H.I.M.'s corvette _Caroline_, likewise fitted out at Pola for a voyage to the coast of South America and Western Africa, followed in her wake, and it was now seen that the frigate was a better sailer than the corvette, a circumstance so much the more satisfactory, that the latter had hitherto been considered the swiftest ship in our navy. The unfavourable state of the weather interfered so much with the works which were to be finished at Trieste, that the embarkation of provisions, swinging the compasses, &c., &c., could only be proceeded with very slowly. At last, the members of the Commission arrived, and the vessel only waited for sailing orders.
