TRY FOR DEEP-SEA SOUNDINGS.
On the 11th an attempt was made to strike deep-sea soundings, but failed from the drawing of a splice used to connect two portions of the spun-yarn employed. On the following day the attempt was repeated by Captain Stanley, unsuccessfully, however, no bottom having been obtained at a depth of 2400 fathoms. Still a record of the experiment may be considered interesting. At three P.M., when nearly becalmed in latitude 1 degree North, and longitude 22 degrees 30 minutes West (a few hours previous to meeting the south-east trade) the second cutter was lowered with 2600 fathoms of line (six yarn spun-yarn) in her, coiled in casks, and a weight consisting of twelve 32 pounds shot--in all, 384 pounds, secured in a net bag of spun yarn. The jolly-boat was in attendance to tow the cutter as fast to whirlwind as she drifted, so as to keep the line during the time it was running out as nearly up and down as possible. The following table shows when each 100 fathoms passed over the stern, the whole 2400 fathoms of line having taken 38 minutes and 40 seconds to run out: COLUMN 1: FATHOM MARK. COLUMN 2: TIME OF PASSING (IN MINUTES AND SECONDS). 100 : 1 0. 200 : 2 5. 300 : 2 30. 400 : 3 35. 500 : 5 0. 600 : 6 15. 700 : 7 35. 800 : 9 0. |
