XVI.—THE C.\LEDONIA —SAN MIGUEL ROUTE. The numerous early explorations of this route have beenalluded to. After the United States Government com-menced systematic surveys, the Isthmus of Darien wasagain explored, in 1870-71-73, by Captain Thomas O. Self-ndge, U. S. N. With regard to this line, two routes were here consid-ered : one from Caledonia Bay, by way of the SavanaRiver, to the Gulf of San Miguel ; the other by way of theSassardi and Morti rivers. Selfridges surveys showed for the former a lowestdivide of 1,000 ft., with insufficient water for lockage ; forthe latter a line of levels showed that the Morti Riveritself, when first struck, had an elevation of over 300 THE ITALIAN TORPEDO RAM, FIERAMOSCA. and revolving cannon, and six torpedo tubes. The 25-cm.(9,84-in.) guns have been proved on trial to give very goodresults. One of these guns, with a charge of 104 km.( lbs ) of battery and a projectile weighing 204 km.( lbs.), had an initial velocity of 617 m. ( ft.)and a penetration of 666 mm. ( in.) in iron, or 452 mm.( >•) in steel, being nearly as much as the 100-tonguns of the Italian Navy. Both these and the 15-cm.() guns have a very long range. Owing to the excellence of her armament, her speed andease with which she was handled on trial, it is expectedthat this ship will be very formidable in action—more so,perhaps, than some of the very heavy battle-ships for whichthe Italians have shown a preference heretofore.
