The sea rose in mountainous waves; the wind blew from all points of the compass; the control over the ship was lost, and she pitched frightfully, all on board expecting every moment to be their last.

Typhoons seldom appear without giving notice of their approach, and some indications may almost be relied on as being sure messengers of warning. Among the principal of these is the barometer. Not unfrequently upon the approach of a typhoon, the barometer seems restless and the mercury keeps oscillating in the tube:—often, when on the borders of a typhoon, the barometer rises suddenly one or two tenths; and Col. Reid gives an instance where two barometers on board the same ship rose half an inch above their usual level.

Mr. Peddington relates the case of the “Earl of Hardwicke”, Captain Neller, as follows:—

“In the Southern Indian Ocean, when near the borders of a typhoon, she was standing off and on to keep out of
