A presentiment of success may have inspired him; but he was ignorant alike of submarine cables and the deep sea. Was it possible to submerge the cable in the Atlantic, and would it be safe at the bottom? Again, would the messages travel through the line fast enough to make it pay! On the first question he consulted Lieutenant Maury, the great authority on mareography. Maury told him that according to recent soundings by Lieutenant Berryman, of the United States brig Dolphin, the bottom between Ireland and Newfoundland was a plateau covered with microscopic shells at a depth not over 2000 fathoms, and seemed to have been made for the very purpose of receiving the cable. He left the question of finding a time calm enough, the sea smooth enough, a wire long enough, and a ship big enough,' to lay a line some sixteen hundred miles in length to other minds. As to the line itself, Mr. Field consulted Professor Morse, who assured him that it was quite possible to make and lay a cable of that length. He at once adopted the scheme of Gisborne as a preliminary step to the vaster undertaking, and promoted the New York, Newfoundland, and London Telegraph Company, to establish a line of telegraph between America and Europe. Professor Morse was appointed electrician to the company. The first thing to be done was to finish the line between St. John's and Nova Scotia, and in 1855 an attempt was made to lay a cable across the Gulf of the St. Lawrence, It was payed out from a barque in tow of a steamer; but when half was laid a gale rose, and to keep the barque from sinking the line was cut away. Next summer a steamboat was fitted out for the purpose, and the cable was submerged. St. John's was now connected with New York by a thousand miles of land and submarine telegraph.
