Taking the bundle, now somewhat larger than a football, he climbed the steep path at the end of the bank, and started for the woods. "I'll be home before supper," he flung back as he disappeared beyond the crest of the bluff. In less than an hour he was back, bringing the sweater minus the rockweed. His face was flushed, and streaked with lines where the perspiration had run down it, and he was breathing hard. Evidently he had been through some sort of strenuous physical exercise. "It's all right, boys," he said, in response to their chaffing. "Just a little secret between me and myself. No, I'm not trying to reduce the size of my head. Later on you'll know all about it." And with that they had to be content. XIII FOG-BOUND Dog-Days began about the 20th of July. Before that the dwellers in Camp Spurling had experienced occasional spells of fog, but nothing very dense or long-continued. Now they got a taste of the real thing. They were dressing fish on the _Barracouta_ one afternoon when a cold wind struck from the southeast. Spurling held up his hand. "We're in for it!" said he. "Feel that? Right off the Banks! In less than an hour we'll need a compass to get ashore in the dory." He was so nearly right that there was no fun in it. The wind hauled more to the east, and in its wake came driving a gray, impenetrable wall. The ocean vanished. The points on each side of the cove were swallowed up. Quickly disappeared the cove itself, the beach, the camp and fish-house, and the bank beyond them. The sloop was blanketed close in heavy mist. Jim made a pretense of scooping a handful out of the air and shaping it like a snowball. "Here you go, Budge!" he exclaimed. "Straight to third! Put it on him! Fresh from the factory in the Bay of Fundy! If this holds on until midnight, we won't be able to see outside our eyelids when we start trawling; there's no moon." "Will you go, if it's thick as it is now?" inquired Lane. "Sure! Here's where the compass comes in. If we stayed ashore for every little fog-mull, we wouldn't catch many hake the next six weeks. This isn't a circumstance to what it is sometimes. I've known it to hang on for two weeks at a stretch. Ever hear the story of the Penobscot Bay captain who started out on a voyage round the world? Just as he got outside of Matinicus Rock he shaved the edge of a fog-bank, straight up and down as a wall. He pulled out his jack-knife and pushed it into the fog, clean to the handle. When he came back, two and a half years later, there was his knife, sticking in the same spot. He tried to pull it out, but the blade was so badly rusted that it broke, and he had to leave half of it stuck in the hole." "Must have had some fog in those days!" was Lane's comment. "Did you say this all comes from the Bay of Fundy?"
