One amusing experience that I had occurred in the Chesapeake Bay in 1898, a few miles below the Potomac River. We were bound from Baltimore to Hampton Roads, and a part of the journey was made on the bottom of the bay. We found this exceedingly interesting, as we could sit in the divers' compartment and view, through the open divers' door, the various kinds of bottom we were passing over, rake up oysters and clams, catch crabs with a crab net, and amuse ourselves in trying to spear fish. The _Argonaut_ at this time had a double pipe mast fifty feet in height, through one of which we got air to run our engines. The other was to provide for the exhaust. We carried a red flag on top of this mast as a warning to surface vessels to keep clear. One afternoon we had been submerged about four hours, running on the bottom in depths varying from twenty-five to forty-five feet; night coming on, we decided to come up and seek a harbor. When we came to the surface we noticed a "bugeye" (a small schooner) "hove to" about fifty yards to the leeward. I blew the centre tank, which brought our conning tower up out of the water, opened the hatch, and hailed the skipper of the bugeye to ask our location and the nearest harbor. He did not wait to answer, but as soon as I yelled he squared away "wing and wing" for the shore. As there was a stiff breeze blowing, it did not take him long to make it, and he ran his vessel right up on the sandy beach, where we saw him and another man--who composed the crew--clamber out over the bow and start to run inland as fast as they could go, leaving their boat without so much as lowering their sails. We finally located ourselves as just north of the mouth of the Rappahannock River, and saw that there was a good harbor very near, so we put in there for the night. After supper, as we were in need of fresh provisions, we went ashore and learned that there was a store a couple of miles down the peninsula. We walked down there and found the store full of natives who were obviously curious as to our identity and business. Finally the storekeeper gathered up his courage and asked us who we were. When he learned that we were down on an experimental cruise in the submarine boat _Argonaut_, he burst into laughter and told us that we had solved a mystery which had stirred up the entire community. He then explained that just about dark one of his neighbors, who never had been known to drink and whose reputation for veracity was excellent, had rushed into the store, followed by his mate. Both were pale from fright, and sank on the porch completely exhausted. They then related a weird tale of seeing a red flag moving down the bay _against the current_ on a buoy. When they went alongside of it they heard a "puff-puff" like a locomotive--that was the exhaust from our engine coming up out of the pipe--and, furthermore, they stated that they had smelt sulphur distinctly. Just then, they claimed, the buoy commenced to rise up and
