"_Evening._--A weary day in a hot broiling sun; no air. After the experiments, L---- said the fault might be ten miles ahead; by that time we should be, according to a chart, in about a thousand fathoms of water--rather more than a mile. It was most difficult to decide whether to go on or not. I made preparations for a heavy pull, set small things to rights and went to sleep. About four in the afternoon, Mr. Liddell decided to proceed, and we are now (at seven) grinding in at the rate of a mile and three-quarters per hour, which appears a grand speed to us. If the paying-out only works well. I have just thought of a great improvement in it; I can't apply it this time, however.--The sea is of an oily calm, and a perfect fleet of brigs and ships surrounds us, their sails hardly filling in the lazy breeze. The sun sets behind the dim coast of the Isola San Pietro, the coast of Sardinia high and rugged becomes softer and softer in the distance, while to the westward still the isolated rock of Toro springs from the horizon.--It would amuse you to see how cool (in head) and jolly everybody is. A testy word now and then shows the wires are strained a little, but every one laughs and makes his little jokes as if it were all in fun: yet we are all as much in earnest as the most earnest of the earnest bastard German school or demonstrative of Frenchmen. I enjoy it very much. "_June 12._ "5.30 A.M.--Out of sight of land: about thirty nautical miles in the hold; the wind rising a little; experiments being made for a fault, while the engine slowly revolves to keep us hanging at the same spot: depth supposed about a mile. The machinery has behaved admirably. O that the paying-out were over! The new machinery there is but rough, meant for an experiment in shallow water, and here we are in a mile of water. "6.30.--I have made my calculations and find the new paying-out gear cannot possibly answer at this depth, some portion would give way. Luckily, I have brought the old things with me and am getting them rigged up as fast as may be. Bad news from the cable. Number four has given in some portion of the last ten miles: the fault in number three is still at the bottom of the sea; number two is now the only good wire; and the hold is getting in such a mess, through keeping bad bits out and cutting for splicing and testing, that there will be great risk in paying out. The cable is somewhat strained in its ascent from one mile below us; what it will be when we get to two miles is a problem we may have to determine.
