The depth of the water was given them, and they were instructed to shoot their nets so as to keep a fathom and a half above the rocky bottom.
A herring net is simply a wall of meshes twelve feet deep, fifty feet long; it sinks to a vertical position by the weight of net twine, and is kept from sinking to the bottom of the sea by bladders or corks. These nets are tied to one another, and paid out at the stern of the boat. Boat and nets drift with the tide; if, therefore, the nets touched the rocks they would be torn to pieces, and the fisherman ruined.
And this saves the herring—that fish lies hours and hours at the very bottom of the sea like a stone, and the poor fisherman shall drive with his nets a yard or two over a square mile of fish, and not catch a herring tail; on the other hand, if they rise to play for five minutes, in that five minutes they shall fill seven hundred boats.
At nine o'clock all the boats had shot their nets, and Christie went alongside his lordship's cutter; he asked her many questions about herring fishery, to which she gave clear answers, derived from her father, who had always been what the fishermen call a lucky fisherman; that is, he had opened his eyes and judged for himself.
Lord Ipsden then gave her blue lights to distribute among the boats, that the first which caught herring might signal all hands.
This was done, and all was expectation. Eleven o'clock came—no signal from any boat.
Christie became anxious. At last she went round to the boats; found the boys all asleep except the baddish boy; waked them up, and made them all haul in their first net. The nets came in as black as ink, no sign of a herring.
There was but one opinion; there was no herring at Inch Keith; they had not been there this seven years.
At last, Flucker, to whom she came in turn, told her he was going into two fathom water, where he would let out the bladders and drop the nets on their cursed backs.
A strong remonstrance was made by Christie, but the baddish boy insisted that he had an equal right in all her nets, and, setting his sail, he ran into shoal water.
