"The air does take it up the form of vapor," said Webb, "and that is why we have such a chilly snow atmosphere. Rapidly melting snow tends to lower the temperature proportionately, just as ice around a form of cream, when made to melt quickly the addition of salt, absorbs all heat in its vicinity so fast that the cream is congealed. But this accumulation of vapor in the air must come down again, perhaps in the form of snow, and so there will be no apparent gain."
"If no apparent gain, could there be a real gain by another fall of snow?" Amy asked; for to inexperienced eyes there certainly seemed more than could be disposed of in time for April flowers.
"Yes," he replied, "a fall of snow might make this whole section warmer for a time, and so hasten spring materially. Do not worry. We shall have plenty of snowstorms yet, and still spring will be here practically on time."
But instead of snow the vapor-burdened air relieved itself by a rain of several hours' duration, and in the morning the river that had been so white looked icy and glistening, and by the aid of a glass was seen to be covered with water, which rippled under the rising breeze. The following night was clear and cold, and the surface of the bay became a comparatively smooth glare of ice. At dinner next day Webb remarked:
"I hear that they are catching a good many striped bass through the ice, and I learned that the tide would be right for them to raise the nets this afternoon. I propose, Amy, that we go down and see the process, and get some of the fish direct from the water for supper."
Burt groaned, and was almost jealous that during his enforced confinement so many opportunities to take Amy out fell naturally to Webb. The latter, however, was so entirely fraternal in his manner toward the young girl that Burt was ever able to convince himself that his misgivings were absurd.
Webb was soon ready, and had provided himself with his skates and a small sleigh with a back. When they arrived at the landing he tied his horse, and said:
"The ice is too poor to drive on any longer, I am informed, but perfectly safe still for foot-passengers. As a precaution we will follow the tracks of the fishermen, and I will give you a swift ride on this little sledge, in which I can wrap you up well."
Like most young men brought up in the vicinity, he was a good and powerful skater, and Amy was soon enjoying the exhilarating sense of rapid motion over the smooth ice, with a superb view of the grand mountains rising on either side of the river a little to the south. They soon reached the nets, which stretched across the river through narrow longitudinal cuts so as to be at right angles to each tide, with which the fish usually swim. These nets are such in shape as were formerly suspended between the old-fashioned shad-poles, and are sunk perpendicularly in the water by weights at each end, so that the meshes are expanded nearly to their full extent. The fish swim into these precisely as do the shad, and in their attempts to back out their gills catch, and there they hang.
The nests are about twelve feet square, and the meshes of different nets are from to and a half to five and a quarter inches in size. A bass of nine pounds' weight can be "gilled" in the ordinary manner; but in one instance a fish weighing one hundred and two pounds was caught, and during the present season they were informed that a lucky fisherman at Marlborough had secured "a 52-pounder." These heavy fellows, it was explained, "would go through a net like a cannon-ball" if they came "head on," and with ordinary speed; but if they are playing around gently, the swift tide carries them sidewise into the "slack of the net," from which they seem unable to escape. There are usually about forty-five feet between the surface of the water and the top of the nets, therefore the fish are caught at an average depth of fifty feet. The best winter fishing is from December to March, and as many as one hundred and seventy pounds, or about two hundred bass, have been taken in twenty-four hours from one line of nets; at other times the luck is very bad, for the fish seem to run in streaks.
