Mr. S. Cullingworth, who arrived in Adelaide on Tuesday from the Kangaroo Island gem field, brought with him some fine tourmalines. They are cylindrical and triangular in shape, and of a perfect pea-blue color, and are the first of the kind which have been found on the field. They came from the Aororangi lease. Mr. Cullingworth also brought from the same lease some large black rock crystals. One of these weighs about 50 lb., and is about 20 in. in length. Its formation is curious, as it has a smaller crystal growing in a lateral direction into one of its longitudinal surfaces. Mr. Cullingworth reports hopefully on the prospects of the field.
