In the Sea I saw many little things which the Seamen call Carvels; they are like a Jelly or Starch that is made with a cast of Blue in it; they Swim like a small Sheep's Bladder above the Water, downwards there are long Fibrous Strings, some whereof I have found near half a yard long. This I take to be a sort of Sea-Plant, and the strings its Roots growing in the Sea, as Duck-weed does in Ponds. It may be reckon'd among the Potential Cauteries; for when we were one day becalm'd, getting some to make Observations thereof, the sportful People rub'd it on one anothers Hands and Faces, and where it touch'd it would make it look very Red, and make it smart worse than a Nettle. In my return for _England_ we struck a Hauksbill Turtle, in whose Guts I found many of these Carvels; so that it's manifest they feed thereon. 'Tis commonly asserted by the Seamen, that they can smell the Pines at _Virginia_ several Leagues at Sea before they see Land, but I could receive no Satisfaction as to this Point; I could not discern any such thing when at a moderate distance, I fear much of this may be attributed to Fancy; for one Day there came three or four full scent to tell me they were certain they smelt the Pines; but it afterwards prov'd that we were at that time 200 Leagues from the Shoar, so that I was satisfied that was therefore meer Fancy. Indeed we thought, by the general Accounts of the Ship, that we had been just on the Coast, but all were deceived by a Current we met with, that at that time set about South-East, or East South-East, which when once becalmed we tried thus: We hoised out a Boat, and took one of the Scuttles that cover'd one of the Hatches of the Ship, tying thereto a great Weight, and a strong long Rope, we let it sink a considerable depth, and then fastening it to the Boat, it serv'd as an Anchor, that the Boat could not drive; then with the Glass and log Line we found the Current set, as I say, Eastward, at the rate of a Mile and a half an Hour. This Current is of mischievous Consequence, it does not always run one way, but as it sets sometimes as we proved Easterly, so does it, as they say, set at other times Westerly, whereby many Ships have been lost; for then the Ships being before their Accounts, they fall in with the Land before they are aware. Thus one Year many Ships were lost on Cape _Hattarasse_, and thereabouts. _Of the AIR._
