 Agate, various, and largely predominating ; rounded and sub- angular, mostly polished or glazed.

No. 2. From Cawoods Hope. See page 6.

Two rolled pieces of fossil Wood.

No. 3. From Pniel. See page 7.

Washed agate gravel *, containing : —

Lydite, rounded (pebbles).

Jasper and Quartzite, subangular and much worn (more than in the gravel from Klip drift).

Fossil Wood, much rolled, one piece.

One fragment of Quartz, off a worn crystal.

Agate, various ; subangular and rounded : largely predominating.

No. 4. From Pniel. See page 7.

Some unwashed ochreous agate gravel. (Not nearly so ochreous as some sent from the Klip-drift diggings by Mr. E. T. Cooper and Dr. G. Grey ; ' Mining Journal,' March 4, 1871.)

No. 5. From Pniel. Page 7.

A small weathered subangular block of light-greenish Amygdaloidal Greenstone, weathering brown.

No. 6. From Pniel. Page 7.

Another, similar, but of a dull-greenish tint. Both are studded with chalcedonic Agates.

No. 7. From Klip drift. See page 7.

A freshly broken piece of a large, rough, angular, yellowish Agate of Chalcedony and Quartz, like that from Hebron.

Nos. 8 & 9. From Klip-drift. Page 7. Washed, coarse, agate gravel†, containing : —

Lydite pebbles, few.

Jasper, some subangular pieces.

Micaceous Haematite, one fragment.

Quartz crystals ; fresh, subangular, and rolled.

Agate, largely predominating ; very various, including much green chalcedony ; subangular and rolled‡. Some of the agate pebbles are very much water-worn, some glazed; and some pebbles have been broken and reglazed.

No. 10. From Hebron. Page 9.

A freshly broken yellowish Agate, like that from Klip-drift (No. 7).

No. 11. From Hebron. Page 9,

Washed, coarse, agate gravel §, containing: —

One small, very round pebble of Lydite ||.


 * One small fragment of Garnet was sent with this parcel.

† One small subangular piece of Garnet was sent in this parcel.

‡ Many of the roundest of the agate pebbles in these gravels of the Vaal are globular agates (chalcedonic nuclei of the amygdaloids) not much rolled.

§ A few subangular and rolled small Garnets accompanied this parcel.

evidence that some of the gravel (and perhaps the Diamond) has been derived from the metamorphic rocks.
 * As in other cases, the Lydite is here much rolled by travel, and bears
