And Jeffrey's Ledge evidently acts in the same way, for though it leaves an open entrance on the north to the trough west of it, the fact that the salinity was the same at eighty fathoms in the trough as at forty fathoms east of the Ledge, shows that little if any salt water flows in across the latter.

Desert Island (Sta- tion 10099) to the eastern basin of the Gulf of Maine (Stations 10100, 10092). (Station 10091), the salinity curves all dip shoreward between the surface and forty fathoms. This is true for the whole column of water between Jeffrey's Bank (Station 10091) and the mouth of the Bay Station 10102). But between Station 10090 and the Bank, the re- verse is the case below forty fathoms. The curve of is espe-.
