From this hill, which he called the Magnetic Hill (Mount Arrowsmith), because on it the north point of the compass deviated to within 3 degrees of the south point, he saw high ranges to the north and north-east; a hill they had already ascended bore 157 degrees 30 minutes, and the flat-topped hill 118 degrees 30 minutes.

From the Magnetic Hill, Mr.Poole went to the latter, and ascended the highest part of it.

The range was rugged, and composed of indurated quartz, and there was a quantity of gypsum in round flat pieces scattered over the slopes of the hills.

The country to the W.and W.N.W.appeared to be very barren.

The range on which they were was perfectly flat at the top, and covered with the same vegetation as the plains below.
